Installation Location
When choosing the location for the control, consider the
following:
Keep dry. Avoid potential leakage onto the control.
RH 90% to 122°F (50°C).
Non-condensing environment.
Do not expose to operating temperatures beyond 32-
122°F (0-50°C).
Provide adequate ventilation.
Keep away from equipment, appliances or other sources
of electrical interference. •
•
•
•
•
Locate the control near pumps if possible.
Provide easy access for wiring and viewing the
control.
Mount approximately 5 ft. (1.5 m) off the finished floor.
Install the electrical junction box to a wall using #10 x
1” wood screws. Wall anchors are recommended when
mounting to sheet rock, wallboard or masonry. •

Rough-In Wiring
Line Voltage Wiring----------------------------------------------------------------------------------- -----------------------------------------------------------------------------------
The control may be mounted to a 4” x 4” electrical junction
box so that the high voltage electrical connections for the
transformer are safely contained.
For ease of service, the circuit breaker or power disconnect
should be located in reasonably close proximity to the
equipment.
All line voltage wire connections are recommended to
be pulled inside a flexible or solid conduit. Always follow
proper wiring practices, building and electrical codes for
your jurisdiction.
Each cable must be pulled to the electrical junction box. It
is recommended to label each cable for easy identification.
All line voltage wires should be stripped to a length of 1/2”
(13 mm).
Pull a three conductor 14 AWG cable for the following
equipment:
Circuit Breaker or Power Disconnect (if applicable)
