Installing the water heater.

NOTICE: This section does not apply if this system is installed as a pre- heater to an existing water heater.

!CAUTION: Do not connect the electricity to the main circuit breaker until the tank is full of water.

NOTICE: Ensure the plumbing is installed to allow for the removal of the storage tank end cover for the maintenance procedures.

See Key to Stub - Out Details Below:

All plumbing and wiring Stub-Outs to be a minimum of 18" above roof frame.

(E)Electrical service (240V, 20-amp required only if using auxiliary electrical backup in tank)

(R) 3/4" Relief Line

(H) Hot Supply to House

(C)3/4" Cold Supply to Rheem thermosiphon tank

NOTICE: Mixing valves should be installed to reduce the point of use water temperature by mixing hot and cold water in branch water lines. Contact a licensed installer or the local plumbing authority for further information.

Install hot and a cold water shut-off valves next to the existing water heater in a convenient location.

Electrical Installation

1.See “Connect the Storage Tank to the Electrical Supply Section” on page 29 for electrical requirements.

2.Install according to Figures on page 15, electrical schematic, and optional electrical connections.

Install Roof - Jack Panel

1.Remove the necessary roofing material,

2.Place the panel over the plumbing and electrical stub-outs and install it with nails or screws,

3.Flash and seal all roof penetrations.

4.Replace the roofing material.

Connect the Plumbing to the Storage Tank, (see the Figure at the top of page 25.)

1.Connect the cold water supply line to the storage tank.

2.Connect the solar hot water line to the Tee Adapter.

3.Connect the drain line to T/P Valve.

To Fill the Water Heater

!CAUTION: On new construction, Do Not fill storage tank and/or charge the closed loop system until the water heater is ready for use. Cover the collectors until the system is filled and charged. Place a tag on the system if it s not filled and charged.

Make certain the drain valve is completely closed.

Open the shut-off valve in the cold water supply line.

Open each hot water faucet slowly to allow the air to vent from the water heater and piping.

As the water heater fills, air will be pushed from the open outlet faucet. A steady flow of water from the hot water

faucet(s) indicates a full water heater.

Check the tank and cold water lines for leaks and repair any found.

Ensure that the storage tank is completely free of air by opening the T/P Valve until it discharges a steady stream of water.

Then close the valve.

The system is now ready to Test and Fill the closed loop as described in the next section of this manual.
