Using the Condensate Removal System
Stores without floor drains use the condensate removal system with a condensate evaporation pan. This is a tray located under the kickplate
with a pump that will pump the water to the top of the case and into a condensate evaporation pan. The condensate evaporation pan has a float
switch that will power its heater when the water rises. These need regular monthly cleaning.
If there is water on the floor at the front of the case, the condensate system will need to be checked.
Cleaning the Condensate Removal System
Both the condensate pump pan and the condensate evaporation pan should be cleaned
regularly with soap and water. A dirty pump pan and evaporation pan are not covered
by warranty service.
Avoid flooding inside the case when cleaning. The condensate removal system
holds 2 gallons of liquid (except for 1-door cases, which only hold 1 gallon of liquid).
Do not use more than this amount of liquid.
Water dumped down the case drain will flow into the pump pan, which will slowly
move the water to the evaporation pan. Block the case drain when you wash out the
case (unless you plan to clean the pump pan at the same time).
The pump or plastic tubing leading to the evaporation pan may become clogged
with debris and must be cleaned.
Note: Anything spilled inside the case will end up in the pump pan and go into
the evaporation pan where it will be heated and may cause an odor. When liquids
are spilled into the pump, the pump pan and evaporation pan should be cleaned
immediately.
Preventative Maintenance for Condensing Units
& Evaporator Coils
Condensing units and evaporator coils should be maintained by licensed, trained, and authorized personnel only.
Vacuum the condenser coil surface every 3 months.
ANNUAL MAINTENANCE
1. Check and tighten all electrical connections.
2. Check all wiring and insulators.
3. Check contactors for proper operation and for worn contact points.
4. Check all fan motors. Tighten motor mount bolts/nuts and tighten fan set screws.
5. Check the refrigerant and oil level in the system.
6. Check the operation of the control system. Ensure all safety controls are operating properly.
7. Check that all defrost controls are functioning properly.
8. Clean the evaporator coil surface.
9. Clean the evaporator drain pan and check the drain pan and the drain line for proper drainage.
10.
Check and tighten all flare connections.
