8-3 Condenser Maintenance
Dirty condenser heat exchange surfaces reduce system capacity.
Air-Cooled Chillers
Brush or vacuum light dirt accumulations. Avoid bending or damaging the fins. Heavy soil
accumulations on the coil require professional steam cleaning, so attempting to wash the
condenser from the outside will only make matters worse.
Water-Cooled
Remove dirt in the condenser tubes with a nylon tube brush. Remove mineral deposits by
circulating AEC Liquid De-Scaling Solution (AEC Part No. A0502600) through the water side
of the condenser. Follow the directions on the container.
The refrigerant side is sealed and requires no routine maintenance.
8-4 Preventive Maintenance Service
A systematic preventive maintenance program helps avoid costly down time. Call the AEC/
Application Engineering Service Department to arrange a schedule of inspections. This service,
described in Bulletin No. 10-106.3, can be tailored to fit your maintenance requirements. These
inspections include:
; Checking refrigerant suction and discharge pressures
; Checking safety and operating conditions
; Checking voltage and amperage of all motors
; Checking all electrical connections
; Checking quantity of refrigerant
; Checking compressor oil level
; Checking lubrication of motor and pump bearings.
; Checking circulating pump operation
; Checking flow through heat exchangers
; Checking compressor efficiency
; Checking noise levels
; Checking cleanliness of equipment area
