F.3. Maintenance And Cleaning
Warnings:
1. Read all the instructions before you attempt to operate the equipment.
2. Always disconnect the unit from the power source before attempting any service or maintenance.
3. Repairs should be performed by a qualified service agency approved by American Panel Corporation.
4. Any changes made to the equipment without the written authorization from the factory will void the warranty.
Daily Cleaning:
1. Before starting, remove the plug from the wall. If the unit is directly hard wired to the power source, shut off the
main power switch or breaker.
Caution: To avoid scratching the stainless steel, DO NOT use scouring pads or any other type of abrasive
material.
2. Wipe down exterior surfaces with a cellulose sponge or a cloth using mild detergent and warm water. Rinse with
cloth or sponge moistened with water to remove traces of detergent, then wipe down with a sanitizing solution.
3. Dry the exterior with a clean, soft cloth. Then, if desired, polish the exterior with a commercial stainless steel
polish.
4. Spaces around the unit must be kept free of debris and soil build-up.
Quarterly:
Remove the clamps that hold the filter screen in place. Carefully remove the filter screen and wash it with warm
hose water or run it (weighted down with a dish rack) through a dishwasher. Shake out excess moisture, and then
remount it in the chiller.
With assistance from the maintenance department, remove the drain pan from underneath the evaporator coil.
Have the plumber open the pipe union outside the chiller which is connected to the floor waste pipe. Rinse out the drain
pan to remove any food particles or water that may have accumulated. Wipe it with a sanitizing solution and return it to its
location under the coil section. Have the plumber reconnect the union.
Semi-Annually:
With assistance from the maintenance department, shut off the main power switch to the chiller. Remove the four
screws that hold each fan cover in place. Remove and clean the covers. Wipe the fan blade surfaces facing the cooling
chamber with a non-caustic cleaning agent and sanitizing agent. Replace the covers and screws, then return the main
switch to the on position.
Preventive Maintenance
As needed:
1. Clean and sanitize the food probe(s) after each use.
2. If dropped or damaged, the probe(s) should be checked for accuracy.
3. Replace the interior light when required.
Monthly:
1. Check and clean the door gasket in jamb.
2. Check that the drain line is open.
Semi-Annually:
1. Check the probe’s accuracy by comparing them with a known accurate thermometer.
2. Check probe cord’s end connector to make sure it is not frayed or damaged.
3. Have a qualified refrigeration service person check the refrigeration charge, control settings, overall operation of
the refrigeration system and the door heater for proper operation.
Note: Never use a high-pressure hose on any part of the blast chiller.
When the UV Sanitizing option is included, the sanitizing recommendations above should be modified.
