START-UP PROCEDURES

INSTALLATION INSPECTION:

The chilled water supply and return connection are 1-½” NPT. The piping should be

copper or PVC and should be insulated. Verify that all connections are made and that all

required valves are open.

Verify that the main breaker or disconnect is on (disconnect for branch circuit to the

chiller, not the chiller disconnect), and check the fuse or breaker size. Compare with the

installation requirements.

Check the incoming voltage and make sure it matches with the indicated nameplate

voltage.

Check input phase gauges by visual inspecting the phase monitor. If correct phase is

supplied, there should be a yellow LED light on the phase monitor.

EQUIPMENT INSPECTION:

Electrical:

Wth the chiller disconnect off, inspect the main control panel (high and low voltage

sections) and check for loose connections. Tighten any loose connections.

Verify that the remote terminal cable is connected to the controller.

Plumbing:

Check water/glycol level in sight glass.

Make sure all valves are OPEN:

• This includes tank shut off valves between pump suction and reservoir

Make sure the strainer blow down vales is CLOSED.

Refrigeration System:

Install refrigeration gauge on high and low side for each system. There is an available

Schrader valve access port and an access port on the suction valve for low side

connections. There are access ports on the compressor discharge valve and one on the

receiver drain valve for high side access. The compressor discharge valve is more easily

accessed.
