Schreiber Chillers 1055 New - Manual (Page 20)

1055 Startup
Initial Startup Procedure
INSTALLATION INSPECTION
Visually inspect the chilled water piping system. There should be two pipe loops; 1” and 1⁄2”.
The piping should be copper or PVC. 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 the nameplate voltage.
Check installation of remote terminal
EQUIPMENT INSPECTION
Electrical
With 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 the following valves are OPEN:
• Tank shut off valves between pump suction and reservoir
• GCHE pump (centrifugal) bypass valve.
• Evaporator isolation valves
Make sure the strainer blow down valve is CLOSED.
Refrigeration System
Install manifold 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 the receiver drain valve for high side access. The
compressor discharge valve is more easily accessed.
