Using the Machine
These control operations (reported below) are performed to check if the machine works properly and should be performed when the machine installation is completed.
1) Open the tap that supplies water to the machine.
WARNING! The water should NOT flow into the chamber; otherwise the water loading solenoid valves are dirty or blocked due to long storage in the warehouse and therefore they must be cleaned.
WARNING! Check that there are no water leaks in the pipe fittings.
2) Check that the suction tubes (located in the lower part of the machine) within the corresponding tanks containing the liquids provided (detergent, neutralizer, and/or others), are correctly inserted.
3) Using the main circuit breaker, supply power to the machine.
4) Check that the water supply flexible hoses are properly connected.
5) At the beginning of the first cycle check the level probes of the liquid suction tubes (detergent, neutralizer and/or others): pull one tube at a time out of the container and check if the corresponding alarm flashes on the display, indicating the need for liquid refilling.
6) After running 3-4 washing tests, clean the water filters placed in the lower compartment of the machine (Fig. 11).
7) Check that the drain trap does not show water leaks and is firmly secured to both the machine and the drain.
8) Check if the pumps correctly suck washing liquids. To do this, check that the liquid rises along the tube connected to them.
Loading the Chemicals
When changing the tanks chemicals, it is required to perform the manual filling of the hydraulic circuit. This phase is important because it prevents any air bubbles present in the pipes from causing an interruption of the cycle following an incorrect reading of the flow meters.
To fill the pipes after changing or refilling the chemicals, proceed as follows:
1) Open the door using the “DOOR” button on the touch screen (4), if the door is already open, leave it opened;
2) Remove the rack if inserted, in order to have full visibility of the washing chamber;
3) Press and hold the button corresponding to the dosing pump you wish to activate to manually load the hydraulic system: key P1 (1) on the touch screen for pump DOS1; key P2 (2) on the touch screen for pump DOS2; key P3 (3) on the touch screen for pump DOS3; key P+ (4) on the touch screen for pump DOS4.
4) Wait a few seconds to see in the lower right part, the area where the chemical inlet holes are present, a constant flow free from air bubbles.
5) Release the button and repeat the sequence from 3 to 4 for the other dosing pumps that need to recharge the hydraulic circuit.
CAUTION! This phase must be performed at the first installation of the machine, in this case, let the liquid flow for a few more seconds to ensure the correct and full loading of the hydraulic system.
Before Use
The glass-washer can be used for cleaning and rinsing glassware and laboratory utensils such as:
- containers, test tubes, beakers, bottles and ampoules; – graduated containers: flasks, graduated cylinders;
- small glassware: lids, spatulas, magnetic laboratory stirrers, stoppers;
- other glassware such as petri dishes, funnels, pieces of tubing/cable, etc…
Emergency Door Release
In the event of a blackout, or any other need in which it becomes difficult to open the glass-washer door, there is a manual emergency release that can only be activated if the door cannot be opened normally.
HAZARD! If the emergency release is used while a program is running, very hot water and chemicals may leak. Therefore, there is a danger of burns, scalding and irritation.
HAZARD! In the case of an emergency release of the door, the load might be contaminated. Be careful while handling it.
Release the door:
1) Push the key supplied in the pack horizontally into the gap between the door and the lid or worktop (1 Fig. 14.1), to position the key correctly, follow the position indicated on the label (1 Fig. 14.2) on the door handle.
2) Upon the door unlock take out the key.
In case of program interruption, proceed with a new treatment of the load.
Preparing the Load
WARNING! The maximum weight that the open door can withstand is 66 lbs (30 kg). The maximum volume of the wash chamber is 44 US gal (165 l).
The glassware to be washed must be placed on the relative racks, making sure that they do not overlap one another.
IMPORTANT NOTE! The cleaning quality depends on the correct loading of the glassware.
Empty any residual liquids from the instruments and containers before inserting them in the chamber, washing all residues well (e.g. disinfectant solutions) in cold water.
Remove non-water soluble residues such as paint, adhesives and polymer compounds using appropriate solvents.
Scoop nutrient media (Agar) out of petri dishes.
Shake out any blood residues and remove any clots.
If necessary rinse the wash load briefly with water to avoid introducing coarse soiling into the machine.
Remove all stoppers, corks, labels, sealing wax residue, etc
Glassware wetted with solutions containing chloride or hydrochloric acid should first be rinsed in cold water and then placed in the drawers for washing. After use, they= should be placed on a settling tank for the time necessary to bring them to the rinse area.
HAZARD! The amount of residual solvents and acids on items going into the chamber should be minimal. There should be no more than a trace of any solvents with a flash point of below 70°F (21°C). Chloride solutions, in particular hydrochloric acid, are corrosive for iron materials.
Make sure that the glassware do not fall off the racks and inserts and do not hang from the grid bars.
Check that injector nozzles and connectors are securely held in position in the baskets or inserts.
Insert the glassware into the appropriate nozzles.
Position container-shaped objects so that liquids can flow easily and, if possible, place tall and heavy tools in the centre of the rack.
Place pointed or sharp objects in such a way as to prevent anyone from being injured by them.
Do not treat broken glass instruments with the glass-washer.
WARNING! Broken glass can result in serious injury when loading or unloading
Components with special geometries must be arranged so as to allow the water to flow out.
Introduce only suitable steel instruments, resistant to corrosion.
Objects made completely or partially of plastic must be resistant to high temperatures.
Nickel-plated and chrome-plated and/or aluminum instruments and tools may not always be suitable for machine treatment. They require special process conditions.
If possible, disassemble the modular instruments following the manufacturer’s instructions and treat the individual parts separately.
Treat small glassware and parts in special inserts.
Before the automatic treatment, check that the lumen and hollow body glassware can be treated internally and remove any obstructions.
Carefully place the load in the supports.
Objects must not be put inside each other nor cover each other. Do not place objects so close to each other that they cannot be washed properly.
Arrange the load so that all surfaces can be reached by the washing liquid. Otherwise they will not be cleaned!
Place the objects so that the liquids can flow out without hindrance.
Tall, narrow, hollow and heavy items should be placed in the centre of the rack. This will ensure better water coverage.
HAZARD! Be very careful when inserting pointed or sharp glassware. Always insert the glassware starting from the bottom, and possibly wearing protective gloves.
When arranging the load, make sure that the spray arms are not blocked by the load itself.
After treatment, the transmission instruments must be cleaned according to the manufacturer’s instructions. After treatment, before reusing the transmission instruments, check that they are working properly, e.g. by spraying liquids into the sink.
Summary of the Rack Loading Operations
Depending on the load, special nozzles or adapters may be required for proper internal cleaning.
Sequence for loading the rack:
1) Fill the rack by arranging the glassware so that all surfaces are reached during washing.
2) Insert the rack into the chamber.
3) Close the door and start the washing program.
Wide-Necked Glassware
Wide-necked glassware (such as beakers, Erlenmeyer flasks and Petri dishes) or cylindrical glassware (such as test tubes) must be washed and rinsed both internally and externally. For this purpose, they should be placed in appropriate inserts and placed in an empty lower or upper rack.
Narrow-Necked Glassware
Narrow-necked glassware (such as narrow-necked Erlenmeyer flasks, flasks and graduated flasks) require the use of racks with special injection nozzles.
Treatment of Glassware
WARNING! Insert only glassware suitable for automatic treatment in glasswasher, according to the manufacturer’s instructions. In particular, follow the information provided by the same manufacturer. Despite compliance with the manufacturer’s instructions, in case of damage or alteration of the glassware, the responsibility will be borne by the glassware manufacturer.
Before starting the treatment, check that:
The external surface of the glassware is clean of material residues (E.g. chloride, hydrochloric acid etc).
The air and spray channels must be clean.
Finally, carry out a test.
Use the recommended liquids (see “Using and Storing Chemicals” in our installation guide).
Programs
The machine leaves the factory with presetting washing programs already entered in the settings menu.
For programs details see the Washing Program booklet.
Suggested Programs vs. Configuration
For a good result, it’s important to choose the right program together with the right load/configuration. To select the programs available, use key P1, P2 or P3 depending on the most suitable program for the level of dirt of the load.
Program Structure
- Drain: It is used to empty the washing chamber.
- Pre-wash: Pre-wash is necessary to eliminate coarse dirt and foamy substances.
- Wash: Depending on the load, washing normally takes place at 113°F- 149°F (45°C- 65°C), adding the appropriate detergent.
- Rinse: The rinsing operation eliminates and neutralizes the chemicals of previous washes.
- Drying: Sufficient drying reduces the risk of corrosion caused by the residual humidity on the load (not available for models without drying system).
Starting the Machine
After checking the integrity and full efficiency of the machine, proceed with start-up:
Power the machine using the main circuit breaker.
Open the door (key 5) to introduce the racks.
Before Starting the Program
Before starting each program, check:
That the filters, positioned on the bottom of the chamber (Fig. 11) are perfectly clean. Clean them, if necessary.
The nozzles of the upper and lower spray arms must be free and clean.
Products must be arranged correctly.
The spray arms must be able to rotate freely. The machine constantly monitors the rotation speed during the program (optional).
Liquid containers must be sufficiently filled. Check for any messages on the display before starting the program.
Closing the Door
Load the glassware and introduce the racks.
Close the door and push it until the lock is activated. The door can be unlocked and opened at any time before the program starts, by pressing the Door key (5)
Selecting the program
To select the programs available, use key P1, P2, P3 or the key P+ (to select programs from 4 to 40) on the control panel (shown above).
Starting the Program
WARNING! Always follow the indicated procedures. Inattentive and frivolous use of electrical devices may lead to risks for the operator.
The manufacturer is not liable for possible damage caused by uncontrolled use of the device.
After selecting the program with relative key, the display shows the selected program and the operating time and temperature.
To start a program, press the START key (7, shown above). Time counter use the first cycle to self calculate the time for each cycle.
Program Execution
WARNING! The program can be interrupted at any time. However, it must be remembered that once interrupted, it must restart from the beginning. Only if it is interrupted in the drying phase can the cycle be considered completed successfully. The glassware must be dried.
HAZARD! In case of contact with the fluids inside the chamber after the cycle has been interrupted before the end of the rinse phase and consequent opening of the door, immediately contact the nearest health center.
Pre-Wash
Pre-wash is carried out with cold water (optional softened water) and without liquids. It mechanically dissolves encrusted organic materials and all proteins on the surface of the glassware. Avoid too high water temperatures.
Wash
It is the actual cleaning cycle. The cleaning chamber heats up until it reaches the specific temperature for the selected program, a temperature that remains stable for the holding time. The cleaning liquid is automatically introduced before the start of the holding time.
Rinsing
Rinsing is carried out with cold water, the machine is standard equipped with the second pump with which it is possible to carry out the neutralization cycle by introducing neutralizing liquid which is designed to reduce the alkalinity and clean the glassware from residues soluble in acid, e.g. limestone and rust.
Dry
The glassware are dried internally and externally with filtered hot air. Good drying reduces the risk of corrosion caused by the residual humidity on the load. Glassware with a very small internal diameter must be dried further.
HAZARD! If the drying phase is disabled, the machine will interrupt the cycle at the end of the rinse phase. It is the responsibility of the user to dry the glassware that have just been washed, using suitable cloths and following the instructions contained in the instruction manual for each individual glassware washed.
HAZARD! If the drying phase is disabled, the glassware must NOT be left inside the machine, at the end of the cycle, wet, for longer than 5 minutes. This is to prevent the proliferation of bacteria and microorganisms. The manufacturer declines any liability for contamination of the glassware during the manual drying stage.
Program End
The message «Finish» with a green background on the display indicates that the program has been carried out correctly. Unlock the door by pressing the Door key (5 in the panel picture from “Programs” section) and open it.
IMPORTANT NOTE! Open the door immediately after the end of the program to avoid condensation forming.
Check the results at the end of the cleaning process. The glassware must be completely clean and dry.
IMPORTANT NOTE! it is the responsibility of the user to ensure that all instruments are dry. If the instruments are still wet: check that the correct washing program has been selected according to the load configuration and that the drying filters have been regularly checked.
- Check hollow glass ware and retreat them if necessary. The hole (lumen) of hollow glassware must be free.
- The injectors must be correctly placed on the connection tube in the cleaning chamber.
- The nozzles and connections to the base grid must be firmly fixed.
If these checks are positive and the program has been carried out without interruptions or malfunctions, the load has been successfully cleaned.
Extracting the Load
At the end of the program and when extracting the load:
Do not force the door open to avoid damaging the device or creating a hazardous condition.
