Section 8 Maintenance

8.2.2 Controller When necessary, clean the controller with warm soapy water. To
prevent moisture damage, always cap the connectors at the back
of the controller tightly. Keep the controller power cable con-
nected, or replace the protective cap (shipped with the sampler)
over the power source connector.
Make sure the two pump drain holes (located on the bottom
right-hand side of the pump, beneath the pump band) are open
and free of debris or buildup.
8.2.3 Sample Bottles The sample bottles have a wide mouth to facilitate cleaning.
Wash them with a brush and soapy water, or use a dishwasher.
You can autoclave the glass bottles.
8.2.4 Suction Line, Pump
Tube, and Discharge
Tube
Clean the suction line, pump tube, and discharge tube by placing
the end of the suction line in a cleaning solution and pumping it
through the delivery system. Rinse with clean water. If these
items are severely contaminated, discard them. For critical sam-
pling applications, refer to Section 8.3, Cleaning Protocols for
Priority Pollutants.
8.2.5 Strainer Clean the strainer with a brush and soapy water.
8.2.6 Air Filter The air filter prevents dust, lint, and other debris from circu-
lating around the cooling system. Clean the filter about every 3
months; more frequently under severe operating conditions.
To remove the filter:
1. Disconnect power from the refrigerator.
2. Remove the screws securing the refrigerator’s grille. (See
Appendix D Replacement Parts.)
3. Remove the grille and filter.
4. Steam clean the filter or wash it in hot, soapy water. After
washing, treat the filter with a standard filter coat.
8.2.7 Condenser Clean the condenser and surrounding areas annually; more fre-
quently under severe operating conditions.
1. Disconnect power from the refrigerator.
2. Remove refrigerator’s back panel. (See Appendix D,
Replacement Parts).
3. Vacuum the fan, compressor, and surrounding areas.
4. Check the fan for freedom of movement. If the fan and fan
motor do not rotate freely, replace the motor. (You cannot
oil the sealed fan motor bearings.)
5. Remove the front grille and filter. Vacuum the condenser
coil and surrounding areas.
6. Clean the filter before replacing it.
7. Replace the back panel and front grille.
