Water Tank Refill

1. Open the cold water supply to the tank.

2. Open a hot water faucet to vent air from the system until

water flows from the faucet, then close.

3. Depress the hot water tank pressure relief valve handle to

ensure there is no air remaining in the tank.

4. Carefully inspect all plumbing for water leaks. Correct as

required.

5. Purge all air from HRP by depressing the Schrader valve on

the HR unit. Allow all air to bleed out until water appears at

the valve.

6. Before restoring the power or fuel supply to the water

heater, adjust the temperature setting on the tank thermo-

stat(s) to ensure maximum utilization of heat available from

the refrigeration system and to conserve the most energy.

On tanks with thermostats and both upper and lower ele-

ments, the lower element should be turned down to 100_F,

while the upper element should be adjusted to 120_F. De-

pending 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 set-

ting to 120_F or the "LOW" position. After thermostat ad-

justments are completed, replace access cover and restore

electrical or fuel supply to water heater.

IMPORTANT: Copper should be used for piping from HRP to

domestic water tank(s).

Use 5/8" (16mm) O.D. copper or

larger. Refer to local codes for hot water piping. Insulate the

water lines between the GHP and the water heater with a

minimum of 3/8" (10mm) closed cell insulation.

Initial Start- -Up

UNIT DAMAGE AND/OR OPERATION HAZARD

Failure to follow this caution may result in unit damage

and/or improper equipment operation.

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 oper-

ate 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_F 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.
