Monthly PM Procedures:

4. Cleaning of all condenser coils on a monthly basis. Condenser coils are a

critical component in the life of the compressor and must remain clean to assure

proper air flow and heat transfer. Failure to maintain this heat transfer will affect

unit performance and eventually destroy the compressor. Clean the condenser

coils with coil cleaner and/or a vacuum, cleaner and brush. Proper care of the filter

will reduce the need for this task. See item #1.

4A. Open lower louver ventilation door for the compressor compartment

and remove mesh filter to view the condenser coil. Use brush attachment

for vacuum in this area to vacuum all particles out of this area.

NOTE: Brush coil in direction of fins, normally vertically as to not damage or

restrict air from passing through condenser.

4B. Remove 8 phillips screws on right exterior side of compressor

compartment to gain access to condensing unit. Vacuum all loose particles

that can be seen being careful not to damage any wires or copper lines.

Accessing the Mechanical Housing

Step 1: Remove 8 screws. Step 2: Pull off side panel. Step 3: Access components.

5. Clean and disinfect rail drains with a solution of warm water and mild detergent

on a monthly basis. It is recommended to open and close the drain valve as the

hot water is flowing through to clean any debris from the internal valve

components.

6. Clean and disinfect drain lines and evaporator pan with a solution of warm water

and mild detergent on a monthly basis. Remove right side access panel on right

end of table. Remove clear plastic drain line from plastic tray of condensing unit

and place pan under end of drain tube. Discard waste water from pan when

cleaning is complete. Re-insert plastic drain tube into position on condensing unit.

7. Inspect all silicone seams at interior of the rail and refrigerated base cabinet on

a monthly basis. Re-apply food grade silicone sealant as needed to any seams

where silicone has peeled away or cracked.

Semi-Annual PM Procedures:

8. For units built after August 28, 2009 with direct pull drain valve. Clean rubber o-

ring seals within drain valve assembly every 6 months by washing with warm

water and mild detergent.

8A. Loosen and remove 4 bolts in drain valve with 5/16” wrench while

holding the nut with 3/8” wrench. Valve will separate into 3 pieces. Carefully

remove o-ring gasket seals for cleaning. Wipe around sealing area of valve to

remove any debris.
