NOTE

For Quick Connect Multi-System

installation only use the Quick

Connect Cord (sold separately).

Connecting the Quick Connect Cord to the two

Water Heaters

1. Check the electrical power is disconnected from

the Water Heater.

2. Remove the front cover (4 screws).

3. Pass the Quick Connect Cord through the wiring

throughway and into the Water Heater.

4. Plug the connector on the Quick Connect Cord

to the connector inside the Water Heater.

5. Connect the ground wire (gray color wire) to the

screw at the base of the Water Heater.

6. Secure the Quick Connect Cord with a clamp.

7. Reattach the front cover (4 screws).

NOTE

If the ground wire is not attached,

electrical noise may cause problems.

NOTE

Do not connect the Remote Controller

to both Water Heaters.

If the Remote Controller is connected

to both Water Heaters, disconnect

unnecessary Remote Controller prior

to installing the Quick Connect Cord.

• The Remote Controller can be connected to

either Water Heater A or B only.

PUMP

Recirculation

Pump

Use a relay when connecting larger pumps

(greater than 100 W)

1. Locate and prepare the pump control wires

as step 1 - 3 for “Connecting the pump control

wire”.

2. Choose a suitable installation location for the

relay where it will be protected from moisture.

3. Connect the pump control wires from the

heater to the signal input on the relay.

4. Cut one of the electrical supply leads and wire it

across the open terminals of the relay.

5. Secure all connections and reattach the front

cover.
