Greenheck RV Series Quick Start Manual

®
This quick start document is intended to help with getting the initial unit startup completed, but does not replace the
IOM. Please read the IOM for all safety information and precautions before performing any work on the equipment.
Complete pre-start checks and blower start-up prior to this procedure.
Fans (*See Model RV/RVE Installation, Operation and Maintenance Manual)
1. Verify discharge air sensor installation at least three duct diameters downstream of the unit discharge.
(Field install)
2. Verify proper phasing of incoming power. See Figure 1 and Figure 2

3. Energize the unit supply and optional exhaust fan:

a. Connect terminal R to terminal G, R to W1 (if applicable), R to Y1 (if applicable) , and R to Y2 (if applicable).

4. Verify blower operation:

a. Check rotation: To reverse the rotation, disconnect and lockout the power, then interchange any two power
leads going to the motor.
b. Check motor amp draw: Compare to motor nameplate FLA - record reading in the *Start-up Report and reduce
airflow. If amp draw is greater than FLA, record any changes you make as well.
c. Check for excessive noise and vibration. If present, check fasteners between motor and impeller, motor and
frame, frame and unit block-off, and make sure they are tight. Check for contact between impeller and inlet
cone.
Energy Wheel (If Present,*see Model RV/RVE Installation, Operation and Maintenance Manual)
1. Verify energy wheel rotation direction (speed may vary depending on wheel model).
2. Check energy wheel motor amp draw, and compare to motor nameplate FLA and record in *Start-up Report.
Cooling (Requires minimum 55°F outdoor air temperature) (Repeat for each circuit)
1. Place a refrigeration manifold gauge set onto each refrigeration circuit.
a. Note: For the high side connection utilize the liquid line service valve.
2. Press the program key on the Carel controller.
3. Scroll down to Ctrl Variables, press the
4. Scroll down to Advanced, press the enter key.

13. Scroll to Cooling Ramp 1 in the Manual Overrides menu. (Note: Be careful, DO NOT do this on either
Compressor Override screen).
14. Set the Override option to Manual and the Demand option to 100%.
15. If hot gas reheat is present in unit, scroll to Hot Gas Reheat Ramp in Manual Overrides menu, and set Override
to Manual and Value to 0%.
16. Restrict the condensing coil until the high side pressure = 450 psig, not to exceed 525 psig.
