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 accordance with the Closed-Loop/Ground Source
Heat Pump Systems Installation Guide).
____ Is vibration isolation provided? (i.e. unit isolation pad,
hose kits)
____ Is unit serviceable? (See
“Unit Location and Clearances,”
____ 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 duct work (if required) correctly sized, run, taped,
insulated and weather proofed with proper unit arrangement?
____ Is the condensate line properly sized, run, trapped and
pitched?
____ Does the indoor blower turn freely without rubbing?
____ 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?
____ Are the compressor bolts removed from the chassis?
____ Have the chassis isolation rails been released?
____ Is there a good seal between the front air panel and the
coil?
Initial Unit Start-up
Start-up with deluxe controls is included below:
Notes:
•
Reference WSHP-IOP-2 for Tracer® ZN510 start-up.
•
Reference BAS-SVX065*-EN for Tracer
®
UC400, UC400-
B start-up.
•
Reference BAS-SVX40*-EN for Trane
®
Air-Fi® start-up.
1. Set the thermostat to the highest position.
Set the thermostat system switch to COOL with the fan
control to AUTO.
The compressor should NOT run
.
2. Reduce the temperature control setting until the
compressor, reversing valve, solenoid valve, and loop
pump are energized.
Adjust water flow utilizing pressure/
temperature plugs and comparing to tables contained in
specification sheet data. Water leaving the heat exchanger
should be warmer than the entering water temperature
(approximately 9
°
F - 12
°
F); blower operation should be
smooth; compressor and blower amps should be within
data plate ratings; the suction line should be cool with no
frost observed in the refrigerant circuit.
3. Check the cooling refrigerant pressures against values in
4. Turn the thermostat switch to the OFF position.
Unit should
stop running and the reversing valve should de-energize.
5. Leave unit off for approximately FIVE minutes to allow for
pressure equalization.
6. Turn the thermostat to the lowest setting. Set the
thermostat system switch to the HEAT position.
7. Adjust the temperature setting upward until the unit is
energized.
Warm air should blow from the register.
A water
temperature decrease of approximately 5
°
F - 9
°
F leaving
the heat exchanger should be noted. The blower and
compressor operation should be smooth with no frost
observed in the refrigeration circuit.
8. Check the heating refrigerant pressures against values in
9. Set the thermostat to maintain the desired space
temperature.
10. Instruct the owner on system operation.
