IMPORTANT WARRANTY  INFORMATION 

Condensers accumulate dirt and require cleaning every 30 days. 
Dirty condensers result in compressor failure, product loss, and lost 
sales, which are not covered by warranty.

If you keep the Condenser clean you will minimize your service 
expense and lower your electrical costs. The Condenser requires 
scheduled cleaning every thirty days or as needed.

Air is pulled through the Condenser continuously, along with dust, 
lint, grease, etc.

A dirty Condenser can result in NON-WARRANTEED part & 
Compressor Failures, Product Loss, and Lost Sales. 

Proper cleaning involves removing dust 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 dirt adequately, please call your refrigera-
tion service company. 

On most of the reach-in units the condenser is accessible in 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 similar to having a dirty coil.

THE CLEANING OF THE CONDENSER IS NOT 
COVERED  BY THE WARRANTY!

HOW TO  CLEAN THE  CONDENSER:

1.   Disconnect the 

electrical power to 
the unit.

2.   Remove the louvered 

grill.

3.   Vacuum or brush the 

dirt, lint, or debris 
from the finned 
condenser coil.

4.   If you have a significant dirt build up you can blow out the 

condenser with compressed air.  

 

(CAUTION MUST BE USED TO AVOID EYE INJURY. 
EYE PROTECTION IS RECOMMENDED.)

5.   When finished be sure to replace the louvered grill. The grill 

protects the condenser.

6.   Reconnect the electrical power to the unit.

If you have any questions, please call TRUE Manufacturing at 636-240-
2400 or 800-325-6152 and ask for the Service Department. Direct 
to Service Department 1(855)372-1368. Service Department 
Availability Monday-Thursday 7:00 a.m. to 7:00  p.m., Friday 7:00 a.m.
