Unit Start-up Procedure
1. Ensure all valves are adjusted to their full open position.
Ensure line power to the heat pump is on.
2. Room temperature should be within the minimum-
maximum ranges of listed in the unit IOM. During start-
up checks, loop water temperature entering the heat
pump should be between 30°F [-1°C] and 95°F [35°C].
3. It is recommended that Trilogy units be first started in
the heating mode, when possible. This will allow liquid
refrigerant to flow through the filter-drier before entering
the EEV, allowing the filter-drier to catch any debris that
might be in the system before it reaches the EEV.
4. Place the unit in Manual Operation mode with the
myUplink Pro app or Service Tool.
5. While in the manual operation mode, turn on the blower
by setting the ECM Target Airflow to a nominal amount.
a. Verify the blower is running and that air is moving
appropriately through the duct system.
b. Verify that the loop pump is running.
c. Set the unit operating mode to Heating
NOTE: The compressor will not start if the blower
and pump are not operating at appropriate levels.
d. Check for vibration, noise, and water leaks
e. Check for warm air delivery at the supply air grilles
within a few minutes after the unit has begun to
operate and that the loop water temperature drop is
within normal range.
f. Allow unit to run 15 minutes so that it reaches a
semi-steady state.
NOTE: Allow three (3) minutes between tests for pressure to
equalize before beginning cooling test.
6. Finally, set the unit to the Cooling Mode
a. Verify that the compressor is on and that the water
temperature rise (cooling mode) is within normal
range.
b. Check for cool air delivery at the supply air grilles
within a few minutes after the unit has begun to
operate.
c. Check the elevation and cleanliness of the
condensate lines. Dripping may be a sign of a
blocked line. Check that the condensate trap is filled
to provide a water seal.
7. If unit fails to operate properly, perform troubleshooting
analysis (see troubleshooting section in this manual).
If the check described fails to reveal the problem and
the unit still does not operate, contact a trained service
technician to insure proper diagnosis and repair of the
equipment.
8. When testing is complete, exit the Manual Operation
Menu and set thermostat to maintain desired comfort
level for normal operation.
9. BE CERTAIN TO FILL OUT AND RETURN ALL
WARRANTY REGISTRATION PAPERWORK.
NOTE: To obtain maximum performance, the air coil should
be cleaned before start-up. A 10% solution of dishwasher
detergent and water is recommended.
