HOT WATER GENERATOR

WARNING!

WARNING! The HWG pump Is fully wired from the factory. Use extreme caution when working around the microprocessor control as it contains line voltage connections that presents a shock hazard that can cause severe injury or death!

The heat pump, water piping, pump, and hot water tank should be located where the ambient temperature does not fall below 50°F [10°C]. Keep water piping lengths at a minimum. DO NOT use a one way length greater than 50 ft. (one way) [15 m]. See Table 4 for recommended piping sizes and maximum lengths.

All installations must be in accordance with local codes. The installer is responsible for knowing the local requirements, and for performing the installation accordingly. DO NOT activate the HWG (turn DIP 3-4 to the ON position) until “Initial Start-Up” section, below is completed. Powering the pump before all installation steps are completed will damage the pump.

Water Tank Preparation

1.Turn off power or fuel supply to the hot water tank.

2.Connect a hose to the drain valve on the water tank.

3.Shut off the cold water supply to the water tank.

4.Open the drain valve and open the pressure relief valve or a hot water faucet to drain tank.

5.When using an existing tank, it should be flushed with cold water after it is drained until the water leaving the drain hose is clear and free of sediment.

6.Close all valves and remove the drain hose.

7.Install HWG water piping.

HWG Water Piping

1.Using at least 1/2” [12.7mm] I.D. copper, route and install the water piping and valves as shown in Figures 20 or

21. Install an approved anti-scald valve if the 150°F HWG setpoint is or will be selected. An appropriate method must be employed to purge air from the HWG piping. This may be accomplished by flushing water through the HWG (as in Figures 20 and 21) or by installing an air vent at the high point of the HWG piping system.

2.Insulate all HWG water piping with no less than 3/8” [10mm] wall closed cell insulation.

3.Open both shut off valves and make sure the tank drain valve is closed.

Water Tank Refill

1.Close valve #4. Ensure that the HWG valves (valves #2 and #3) are open. Open the cold water supply (valve #1) to fill the tank through the HWG piping. This will force water flow through the HWG and purge air from the HWG piping.

2.Open a hot water faucet to vent air from the system until water flows from faucet; turn off faucet. Open valve #4.

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

ensure that there is no air remaining in the tank.

4.Inspect all work for leaks.

5.Before restoring power or fuel supply to the water heater, adjust the temperature setting on the tank thermostat(s) to insure 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 [38°C] or the lowest setting; the upper element should be adjusted to 120-130°F [49-54°C]. Depending upon the specific needs of the customer, you may want to adjust the upper element differently. On tanks with a single thermostat, a preheat tank should be used (Fig 21).

6.Replace access cover(s) and restore power or fuel supply.

Initial Start-Up

1.Make sure all valves in the HWG water circuit are fully open.

2.Turn on the heat pump and allow it to run for 10-15 minutes.

3.Set S3-4 to the “ON” position (enabled) to engage the HWG. See Figure *.

4.The HWG pump should not run if the compressor is not running.

5.The temperature difference between the water entering and leaving the HWG coil should be approximately 5-10°F [3-6°C].

6.Allow the unit to operate for 20 to 30 minutes to insure that it is functioning properly.
