Daily, or as often as needed
Ì
Checking process fluid level in the pump tank
Check the process fluid level in the water level gauge on the back of the
chiller. If low, see Filling the Chiller, in the Installation section.
Ì
Verifying pump discharge pressure
While the pump is running, check that the pump pressure gauges are within
range. To change the pressure open or close the To Process valve.
Ì
Inspecting piping for leaks
Check to see that pipes are not leaking. Look for standing water on the floor
or inside the chiller cabinet.
Ì
Inspecting the condenser coil for debris
(air-cooled models only). Remove the wire mesh side panel and filter in front
of the condenser coil. Remove any debris from the coils.
IMPORTANT: We recommend wire terminations being tightened during any servicing of the chiller.
Weekly, or as often as needed
Ì
Checking temperature and pressure readings
Check that the temperature displays on the control screen, and that the
pressure gauge indicates normal operation.
Ì
Checking efficiency
Review the performance data on the Maintenance Log found in the
Appendix. If you notice a decrease in efficiency over time, check all heat
transfer surfaces of the evaporator and condenser for fouling. Clean as needed.
Ì
Checking refrigerant site glass
There should not be any bubbles. See Checking Refrigerant Charge, in the
Maintenance section.
Ì
Checking reservoir level
Check the water level gauge on the back of the chiller. If fluid level is low,
fill. See Checking Reservoir Level, in the Maintenance section.
