Section 6, Wiring the Electrical System
6-2 POLAR™ HD Heating Module
6.3 120 VAC
• The POLAR™ HD Heating Module is equipped with two 1500
watt, 120 VAC immersion elements (other voltages and
frequencies are available). The connections for the electrical
supply are on the top left side of the POLAR™ HD Heating
Module, under a cover, labeled AC power.
• The power wires for the AC immersion elements are three 14
gauge stranded copper leads that use standard AC color code
(black-hot, white–neutral, green-ground). These are to be
connected using standard 120 VAC electrical connectors and
terminals.
• There are two sets of power wires, one set with black heat
shrink (primary) and one set without heat shrink (secondary).
Each individual set must be connected to a separate AC circuit
breaker. The primary set is connected to the single AC element
side of the POLAR™ HD Heating Module. The secondary set of
wires is connected to the other AC element. If only one AC
circuit breaker is available, you must connect to the primary
wire set only. Once the connections are completed, the wires
are to be inserted back into their compartment and the cover
secured.
• The ground wire (green) is shared between the two connections.
Do not operate the electric immersion elements until water is added
to the POLAR™ HD Heating Module and Distribution Module, and all
trapped air has been removed.
6.4 Remote Operating Panel Cable
• One connection on top of the POLAR™ HD Heating Module is a
multi- wire, sheathed cable with a 9 pin connector. This
connects to a matching connector on a short adapter cable. The
other side of the cable has a 10 pin connector that connects to a
25’ remote cord. This remote cord then plugs directly into the
Remote Operating Panel. Refer to Figure 6-1: System Wiring.
• If the Distribution Module is used, refer to Section 9, Installing
the Distribution Module.
