If you lack the necessary skills required to properly install

the electrical wiring to this solar storage tank water heater,

do not proceed but have a qualiﬁ ed electrician perform the

installation.

When making the electrical connections, always make sure:

• The electrical supply has the proper overload fuse or

breaker protection.

• Wire sizes and connections comply with all applicable

codes.

• Wiring is enclosed in approved conduit (if required by local

codes).

• The solar storage tank water heater and electrical supply

are properly grounded.

Important: Do not use an extension cord to supply power

to this solar storage tank water heater. Be sure the power

supply is completely grounded before making connections.

Figures 4, 5, and 6 are provided as reference drawings

for the 120/240v 2-wire models only. Always reference the

wiring diagram located on the solar storage tank water

heater for the correct electrical connections and connect

the electrical supply to the solar storage tank water heater

in accordance with local utility requirements and codes.

When installing the electrical wiring to the solar storage

tank water heater:

1. Be sure tank is completely filled with water before

making any electrical connections. (See Figure 2)

Notice: Applying electrical power to elements that are not

submerged in water will destroy them. The manufacturer

will not warranty any elements damaged in this manner.
