UNIT Checklist
1
Ensure Voltage is within an acceptable range for the unit and wiring and fuses/breakers are
properly sized. Check low voltage wiring is complete
2
Ensure transformer has properly selected control voltage tap. 208-230V units are factory
wired for 230V operation unless specified otherwise.
3
Ensure entering water temperatures are within operating limits of Performance Table.
4
Verify low water temperature cut-out is properly set. Check flow switch is operating
5
Verify inlet and outlet water temperatures on both Load and source are recorded for each
heat pump upon startup. This check can eliminate nuisance trip outs and high velocity
water flows that can erode heat exchangers.
SYSTEM Checklist
1
Check load and source water temperature for proper range and also verify heating and
cooling set points for proper operation.
2
System water pH is 7.5 - 8.5. Proper pH promotes longevity of hoses and fittings.
3
Verify all hoses are connected end to end when flushing to ensure debris bypasses unit
heat exchanger and water valves etc. Water used in the system must be potable quality
initially and clean of dirt, piping slag, and strong chemical cleaning agents. Verify all air
is purged from the system. Air in the system can cause poor operation or system corrosion.
