PREVENTATIVE

MAINTENANCE

SCHEDULE

To maintain the best perfor- mance, follow the mainte- nance schedule and record information in the Maintenance Log in the Appendix.

●Daily, or as often as needed

❒Checking electrical connections

Make sure electrical connections are properly seated. See Checking Electrical Connections, in the Maintenance section.

❒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.

❒Verifying pump discharge pressure

While the pump is running, check that the pump pres- sure gauges are within range. To change the pressure open or close the From Process valve.

❒Inspecting piping for leaks

Check to see that pipes are not leaking. Look for standing water on the floor or inside the chiller cabi- net.

❒Inspecting the condenser coil for debris

(air-cooled models only) Remove the wire mesh side panel in front of the condenser coil. Remove any debris from the coils.

●Weekly, or as often as needed

❒Checking temperature and pressure readings Check that the temperature and pressure display on the control screen, and that the pressure gauge indicates normal operation.

❒Checking efficiency

Review the performance data on the Maintenance Log found in the Appendix. If you notice a decrease in effi- ciency over time, check all heat transfer surfaces of the evaporator and condenser for fouling. Clean as needed.

❒Checking refrigerant site glass

There should not be any bubbles. See Checking Refrigerant Charge, in the Maintenance section.

❒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.
