Mechanical Controller Instructions
OFF: shut the compressor off.
Temperature range from 7 (coldest) to 1 (warmest).
CAUTION:
Setting the temperature control to the coldest setting may cause the
evaporator coil to freeze and ice up. This will eventually result in a warmer cabinet
temperature.
Cleaning and Maintenance
Condensers accumulate dirt and dust and require cleaning every 30 days. Dirty condensers result in
compressor failure, product loss, and lost sales -- which are not covered by warranty.
Air is pulled through the condenser continuously along with dust, lint, grease, etc. If you keep the condenser
clean you will minimize your service expense and lower your electrical costs. The condenser requires
scheduled cleaning every days or as needed. A dirty condenser can result in non-warranted part and
compressor failures and product loss.
Proper cleaning involves removing debris from the condenser by using a soft brush or vacuuming the
condenser with a shop vac or using Co2, nitrogen or pressurized air.
If you cannot remove the debris adequately please call you refrigeration service company.
On most of the reach-in units the condenser is accessible at the rear of the unit. You must remove the cabinet
grill to expose the condenser. The condenser looks like a group of vertical fins. You need to be able to see
through the condenser for the unit to function at maximum capacity. Do not place filter material in front of
condensing coil. This material blocks air flow to the coil which is similar to having a dirty coil.
CLEANING THE CONDENSER COIL
Required Tools:
• Phillips screwdriver.
• Stiff bristle brush.
