Miele A620, A621, A622 Injector Module

Miele-A620,-A621,-A622-Injector-Module

Product Information
The product is an injector module that comes in three models: A 620, A 621, and A 622. It is used for a specific application and is accompanied by an operating manual in multiple languages.

The product is designed to be used with a specific cart/wagon,as described in the manual. It has a display for easy operation and troubleshooting. The product also includes different accessories such as hold grids for specific models.
The product has specific capacity limits for different types of containers, including laboratory bottles, round flasks, Erlenmeyer flasks, and measuring flasks. The maximum volumes allowed vary depending on the model.
The product also has a specific assembly process, including attaching and detaching hold grids.

Product Usage Instructions

Refer to the user manual of the cart/wagon for instructions on how to insert and remove the injector module.
Prior to loading and starting any program, check the laboratory bottles and different types of flasks for proper attachment and secure fastening of rinsing devices such as sleeves and nozzles.
For each model (A 620, A 621, A 622), refer to the respective section in the user manual for the maximum volume limits for different types of containers (laboratory bottles, round flasks, Erlenmeyer flasks, measuring flasks).
When assembling the hold grid, follow the steps provided in the user manual. Place the struts of the hold grid onto the module and rotate the brackets on the struts. Ensure that the locking hooks on the brackets are engaged. Repeat this process for the other three struts. Then, slightly pull down the locking hooks on the brackets and rotate the brackets. Repeat this process for the other three struts. Finally, lift the hold grid off the module when needed.

Appropriate use

This module can be used to reprocess machine-processable laboratory glassware and utensils in a Miele washer-disinfector for laboratory glassware and utensils. Follow the operating instructions for your washer-disinfector as well as the instructions of the glassware and utensil manufacturer on how to reprocess their items by machine.
The A 620, A 621 and A 622 injector modules are suitable for reprocessing narrow-necked laboratory glassware.
The modules are to be used in an A 503 mobile unit.
The washer-disinfector is generally referred to as “the machine” in these operating instructions. Reprocessable laboratory glassware and utensils are referred to as “items” if they are not more closely defined.

Queries and technical problems
If you have any queries or technical problems that you would like to discuss please contact Miele. Contact details can be found at the back of the Operating Instructions for your washer-disinfector or go to www.miele- professional.com.

Warning and Safety instructions

Read the operating instructions carefully before using this load carrier.
This will help protect users from personal injury, and help protect the load carrier from damage.
Keep these operating instructions in a safe place.

Please also read the operating instructions for your washer-disinfector and pay particular attention to the Warning and Safety instructions.

The module is approved solely for the applications specified in the operating instructions. Components such as nozzles may only be replaced with Miele accessories or genuine Miele original spare parts.
Alterations or conversion of the machine, or using it for purposes other than those for which it was intended, are not permitted and could be dangerous.
New load carriers must be cleaned in the washer-disinfector without a load prior to first use.
Inspect all load carriers as described in the “Maintenance” section in the operating instructions for the cleaning machine.
Only items which have been declared by their manufacturer as suitable for machine reprocessing may be processed. The manufacturer’s specific reprocessing instructions must be observed.
Broken glass can result in serious injury when loading or unloading.
Damaged glass items must not be reprocessed in the machine.
Only ever place empty, unloaded modules in the mobile unit.
Check that they are correctly engaged before loading them.
Modules must be completely emptied before removing them.
Placing loaded modules in mobile units or removing them can cause damage to the wash load and cause injury should glassware be broken.
The reprocessing result must be checked as necessary using a suitable test method and not just by a visual check.
Miele cannot be held liable for damage caused by non-compliance with these Warning and Safety Instructions.

Areas of application

The operating instructions for the loading carriage describe how to insert and remove the modules.
To check before loading the machine and before starting a programme

Check that fittings such as irrigation sleeves and injector nozzles are securely screwed into position.
- Make sure that all screw connectors are fitted with injector nozzles, adapters, irrigation sleeves or blind stoppers to ensure that all fittings in use are supplied with sufficient standardised pressure.
  Damaged fittings such as injector nozzles, adapters and irrigation sleeves must not be used.

Fittings not equipped with wash items do not have to be replaced blind stoppers.

Is the module correctly docked to the water supply in the injector unit?

Preparing the load

Ideally, a gap should be left between neighboring items when they are reprocessed.

An additional frame can be mounted when reprocessing particularly fragile items. This prevents them from touching each other if they are moved by the force of water during reprocessing.

If bulbous items are loaded in neighboring positions in the module, the items may touch each other.
If the cleaning and rinsing requirements are particularly high, a different position must be selected on the module for these items.

Damage to the items.

If items touch each other during reprocessing, damage can occur at the points of contact, for example, the items may become scratched or the glass may break.

If the items are fragile:

Select a different position on the module
Use a frame
Select a module with a greater distance between the nozzles

Damage to the items.
The rims of the items should rest fully on the support of the injector nozzle. If items dislodge neighbouring nozzles, damage can occur during reprocessing, for example, the items may become scratched or the glass may break.

Use:

A different position on the module
A module with a greater distance between the nozzles

The tip of the nozzle is designed so that it can touch the bottom of a piece of glassware during reprocessing. The shape of the protective cap ensures that water can flow out of the nozzle during repro-cessing.

Damage to the items.

If items are reprocessed frequently, their surfaces may be damaged at the point where the nozzle touches them, for example, the items may become scratched.
If the items are fragile, select a shorter nozzle to prevent the nozzle from coming into contact with the item.

If the cleaning and rinsing requirements are particularly high, a shorter nozzle must be selected.

Glassware must not extend beyond the sides of the load carrier.

Installation

Tools required:
– 9 mm Spanner (WAF 9)

Installation

Screwing the injector nozzle onto the module

Lift up the support on the injector nozzle and screw the injector nozzles into the required position 1.
Use the spanner to tighten the injector nozzle 2.
Slide the support on the injector nozzle downwards until it rests on the water supply pipe 3.
Screw the other injector nozzles into the required positions.

Securing the frame

Position the rods for the frame on the module 1.
Turn the supports on the rods of the frame 2.
The locking retainers on the supports lock into place 3.
Repeat the process for the other 3 rods.

Removing the frame
