Heat Recovery Package | 11

Initial Start-Up

Make sure all valves in heat recovery water piping system are open. NEVER OPERATE

HR PUMP DRY.

1. Turn on the heat pump. The HR pump should not run if the compressor is not running.

2. Turn HR switch to the “ON” position. The pump will operate if entering water temperature to

HR is below 120° F.

3. The temperature difference between the water entering and leaving the heat recovery should be 5° to 15° F.

4. Allow the unit to operate for 20 to 30 minutes to ensure it is functioning properly. The pump should shut off when the water temperature entering the heat recovery reaches 120°F.

6. Before restoring the power or fuel supply to the water heater, adjust the temperature setting on the tank thermostat(s) to ensure maximum utilization of the heat available from the refrigeration system and conserve the most energy. On tanks with both upper and lower elements and thermostats, the lower element should be turned down to 100° F, while the upper element should be adjusted to 120° F.

Depending upon the specific needs of the customer, you may need to adjust the upper element differently. On tanks with a single thermostat lower the thermostat setting to

120° F or the “LOW” position. After thermostat adjustments are completed, replace access cover and restore electrical or fuel supply to water heater.
