Daily, or as often as needed

❒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 Maintenance section entitled, Checking the Reservoir Level.

❒Verifying pump discharge pressure

While the pump is running, check to ensure that the pump pressure gauge (located on the front of the chiller) is within range. To change the pressure, open or close the “To Process” valve (factory optional).

❒Inspecting piping for leaks

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

❒Inspecting the condenser coil for debris

Check the condenser for adequate air flow. Check the condenser face for dirt and clogging. If dirt or clogs are present, clean the condenser, see Maintenance section entitled, Cleaning the Air-cooled Condenser. Check, clean, and/or replace the filter at the air inlet of the air-cooled condenser coil, as needed.

Weekly, or as often as needed

❒Checking temperature and pressure readings

Check that the temperature displays on the control screen and the reading on the pressure gauge (located on the front of the chiller) indicates normal operation. See Description section entitled, Pump Curve: EarthSmart ECM Series Chillers.

❒Inspecting the filter

Check, clean and/or replace the filter at the air inlet of the air-cooled con- denser coil, as needed. see Maintenance section entitled, Cleaning the Air- cooled Condenser.

❒Checking refrigerant site glass

There should not be any bubbles. See Maintenance section entitled, Checking the Refrigerant Charge and Quality.

❒Checking reservoir level

Check the water level gauge on the back of the chiller. If fluid level is low, fill, see Maintenance section entitled, Checking Reservoir Level.
