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.
