Section 9
Maintenance
WARNING
Potential Electrical Shock and Fire hazards. Only qualified personnel should
conduct the tasks described in this section of the manual. Always disconnect
power to the sampler before performing any maintenance or service.
WARNING
Fire Hazard. Models of AWR Samplers with cabinet heaters may ignite flammable
materials and cleaning solvents. DO NOT use any flammable liquids or materials to
clean or disinfect either the Sampler or any other component under the cabinet
hood of the AWR Samplers. Before performing any cleaning operation, disconnect
the AWR Sampler from its power source. If cleaning of the Sampler controller and
pump cannot be done with water, the Sampler must be disconnected and moved to
a location outside of the cabinet for cleaning. Allow sufficient time for the Sampler
controller/pump to dry before reinstalling and putting it back into service.
CAUTION
Biological sample hazard. Follow safe handling protocols during contact with
sample bottles and sampler components. Disconnect the sampler from power to
disable the pump before handling.
Danger
Potential Electrical Shock and Fire Hazard
Do not attempt to clean the controller compartment heater by spraying it with
liquids of any kind. The heater should be protected from moisture such as ice and
snow.
9.1 Cleaning the sampler
9.1.1 Cleaning the refrigerator
Clean the condenser fins and coils with a brush or vacuum every 6 to 8 months to
maintain efficient heat transfer.
9.1.2 Cleaning the sampler cabinet
Clean the interior and exterior of the sampler cabinet with a damp sponge and mild
detergent. Do not use abrasive cleaners or solvents.
9.1.3 Cleaning the sample bottles
Clean the bottles using a brush and water with a mild detergent, followed by a fresh water
rinse and a distilled water rinse. Glass bottles may also be autoclaved.
9.1.4 No lubrication required
The sampler
does not
require routine lubrication. Do not lubricate the pump tube with
petroleum jelly, silicone grease, oil, or any other lubricant, as this will substantially reduce
the life of the pump tube and roller assembly.
9.2 Adjusting the refrigeration compartment door (AWRS only)
Since the door gasket may compress slightly over time, an adjustment screw is provided
to allow the door to be tightened.
Procedure:
1.
Loosen the lock nut (
).
2.
Rotate the tension adjustment screw until the door shuts tightly.
