The Whalen Company Heat Pump Startup Instructions
The Whalen Company’s heat pumps feature innovative design and energy efficiency, making them valuable climate control solutions for high-rise residential and commercial buildings. Although operating these units is fairly straightforward, it’s important to check for safety and functionality after installation. To help ensure your unit is ready for use, this set of Whalen Company heat pump startup instructions walks you through the process from start to finish.
This guide covers water-source units from the Closetline, such as the CASH/V006-060, as well as models from the Whisperline series, including the VP-A-020x–VP-A-120x and WR 006-060. Any testing or repairs discussed in this article will need to be completed by an authorized technician.
Starting the Unit
- Step 1. Turn on the blower - Turn the thermostat fan to the “on” position to start the blower.
- Step 2. Balance airflow (if needed) - Locate the diffusers and adjust the dampers to redirect air as needed throughout the building.
- Step 3. Open all valves - Turn all valves to the fully-open position.
- Step 4. Turn on line power - Power on the rest of the unit by switching on all electrical circuit breakers connected to the machine.
- Step 5. Check the initial voltage - Make sure the starting voltage is within the range given on the unit’s data plate.
Activating the Compressor
- Step 1. Initiate a cooling call - Set the thermostat to its highest setting, switch to cool mode and then gradually lower the temperature.
- Step 2. Wait for the compressor to activate - Continue lowering the thermostat setting until the compressor turns on. Note that some units have a built-in five-minute time delay before the compressor starts.
- Step 3. Verify cool air at the supply grille - Confirm that cool air is flowing from the supply grille once the compressor starts; if not, contact an authorized technician for further assistance.
Verifying System Operation
- Step 1. Select an operating mode - Set the machine to either heating or cooling mode after checking the compressor.
- Step 2. Verify loop circulation - Check for proper water flow using the pressure/temperature (P/T) ports on the “In” and “Out” loop connections.
- Step 3. Run the unit for 10-15 minutes - Let the machine operate for 10-15 minutes before continuing with additional checks.
- Step 4. Inspect the condensate line - Ensure the condensate line is elevated, clean and clear. Additionally, make sure the trap is filled with water.
- Step 5. Confirm proper operating voltage - Recheck the voltage to verify it's still within the acceptable range listed in the unit’s electrical data table.
- Step 6. Measure “In” and “Out” loop temperature differential - Use the P/T ports to assess the temperature difference between the loop's inlet and outlet.
- Step 7. Monitor return and supply air temperature differential - Check the temperature difference between the return air and supply air registers.
- Step 8. Listen for the reversing valve - Turn the thermostat to “OFF” and wait for a hissing sound. If you hear it, the reversing valve is functioning; if not, contact a licensed technician.
- Step 9. Check system operation in the other mode - Switch the unit to heating or cooling, depending on which setting was tested first, and repeat the steps above to verify proper function.
Initiating Normal Operation
- Step 1. Install open access panels - Secure any remaining access panels in their proper place on the machine.
- Step 2. Select the desired mode - Choose either heating or cooling based on current climate control needs.
- Step 3. Set the thermostat temperature - Adjust the thermostat to your preferred temperature setting.
- Step 4. Begin normal operation - You may now use the unit normally.
