Pre-Start-up Checklist

Before energizing the unit, the following system devices must be checked:

____ Is the high voltage power supply correct and in accordance with the nameplate ratings?

____ Is the field wiring and circuit protection the correct size?

____ Is the low voltage control circuit wiring correct per the unit wiring diagram?

____ Is the piping system clean/complete and correct? (A recommendation of all system flushing of debris from the water-

to-refrigerant heat exchanger, along with air purging from the water-to-refrigerant heat exchanger be done in accor- dance with the Closed-Loop/Ground Source Heat Pump Systems Installation Guide).

____ Is vibration isolation provided? (i.e. unit isolation pad, hosekits)

____ Is unit serviceable? (See clearance specifications on page 6).

____ Are the low/high-side pressure temperature caps secure and in place?

____ Are all the unit access panels secure and in place?

____ Is the thermostat in the OFF position?

____ Is the water flow established and circulating through all the units?

____ Is the zone sensor correctly wired and in a good location?

____ Has all work been done in accordance with applicable local and national codes?

____ Has heat transfer fluid been added in the proper mix to prevent freezing in closed system application?
