7 SERIES 700A11 INSTALLATION MANUAL

To maximize the benefits of the hot water generator a

minimum 50-gallon water heater is recommended for

higher demand applications, use an 80-gallon water

heater or two 50-gallon water heaters connected in a

series as shown below. Two tanks plumbed in a series

is recommended to maximize the hot water generator

capability. Electric water heaters are recommended. Make

sure all local electrical and plumbing codes are met for

installing a hot water generator. Residential units with hot

water generators contain an internal circulator and fittings.

A water softener is recommended with hard water (greater

than 10 grains or 170 total hardness).

NOTES:

1) Using a preheat tank, as shown in Figure 12, will

maximize hot water generator capabilities. 2) The hot water

generator coil is constructed of vented double wall copper

suitable for potable water.

Water Tank Preparation

To install a unit with a hot water generator, follow these

installation guidelines.

1. Turn off the power to the water heater.

2. Attach a water hose to the water tank drain

connection and run the other end of the hose to an open

drain or outdoors.

3. Close the cold water inlet valve to the water heater tank.

4. Drain the tank by opening the valve on the bottom

of the tank, then open the pressure relief valve or hot

water faucet.

5. Flush the tank by opening the cold water inlet valve to

the water heater to free the tank of sediments. Close

when draining water is clear.

6. Disconnect the garden hose and remove the drain valve

from the water heater.

7. Refer to Plumbing Installation and Hot Water

Generator Startup.

NOTE:

This configuration maximizes hot water

generator capability.
