cleaner which may be harmful to the metering chamber cover. Do not use
solvents such as acetone, benzene, carbon tetrachloride or lacquer thinners.
Grease and oil may be removed with kerosene or aliphatic naphtha (non-
aromatic).
4. Check and clean O-rings in metering chamber cover.
Replace if damaged, worn or brittle.
5. Clean metering chamber using mild detergent.
Do not use any cleaner which may be harmful to the clear acrylic (for
example, petrochemical solvents, as noted above). Do not use abrasives or
“scouring” compounds.
6. Check discharge tubing for wear and replace as necessary.
7. Check pinch valve to ensure free movement.
8. If possible, run sampler through several sampling sequences in clean
water.
9.2 Maintenance of Refrigerator
9.2.1 Cleaning
Never use acids, chemical thinner, gasoline, benzene, or
the like for cleaning ANY part of the refrigerator. Boiling
water and benzene may deform or damage the plastic
parts. CAUTION
1. Turn off power.
2. Remove containers and trays.
3. Wash interior liner with a warm solution of two tablespoons of baking
powder per quart of water. Rinse and wipe dry. Do not use soaps,
detergents, scouring powder, spray cleaners or the like on the interior liner
as it may cause odors in the refrigerator compartment.
4. Wipe the exterior surface with a soft cloth dampened with soapy water and
then dry with another soft cloth. Common appliance spray cleaner may be
used for exterior only. Use only mild soapy water to clean door gaskets.
9.2.2 Temperature Control
Refrigerator temperature can be regulated by adjusting the cold control. The
closer to “MAX” position, the lower the temperature. Recommended setting is
between “3 – 4”. However, refrigerator temperature will vary depending on the
ambient air temperature and on the frequency with which the door is opened.
This refrigerator may cycle on and off more frequently than regular size
refrigerators. This is normal because of its compactness.
