SAFETY & WARNINGS
1. Even when the heat tapes are disconnected, as long
as the circuit breaker is on and power is running to
the unit, voltage is still being applied to the yellow
heat tape leads. Therefore, never touch the ends of
the yellow leads or let the two leads touch each other.
Do not let the two yellow heat tape leads contact any
component inside the unit.
2. Any installation involving electric heater wiring must
be grounded to earth to protect against shock and
fire hazard. Suitable ground fault detection and
interrupting systems must be in use at all times to
reduce shock and fire hazard and to protect personnel
and equipment.
3. Electric wiring to heating elements must be installed
in accordance with National Electrical Code (NEC)
requirements, as well as other local and applicable
electrical codes and third party standards.
4. Only UL listed, 4X, raintight conduit hubs and cable
glands are to be used. The hub is to be connected to
the conduit of a rigid conduit system before the hub
is connected to the enclosure.
5. Ensure a sealed, watertight installation. Waterproof all
cable runs, seal all box joints, and properly terminate
wiring.
6. Shut off system circuit breaker prior to beginning
installation.
PRIOR TO INSTALLATION
1. Installation and service of this device should be
perfomed by a qualified electrician.
2. Refer to page 8 of the GF Pro Instruction Manual to
learn about optional equipment available for the GF
Pro system which might be of interest to you.
3. Before beginning installation, lay out the system
components in their approximate location on the site
to help you visualize the system and evaluate exact
component and junction box placement, as well as
required cable and conduit lengths.
4. It is recommended to read these installation instruc-
tions prior to beginning installation.
INSTALLATION
1. Install the control box. Locate and install the control
box on a wall using the box itself as a template to
determine the mounting hole footprint. Install the
box to a solid, stable surface capable of supporting
four times the weight of the box, or about 20 pounds.
Use all four mounting holes. Install the control box
to the wall using heavy-duty mounting hardware
long enough to fasten the box securely. Do not fully
tighten the mounting hardware at this time. Leave the
mounting hardware loose enough to work the conduit
into place. Hardware will be fully tightened following
installation of the conduit.
2. Once the control box is installed but with the
mounting hardware not yet fully tightened, with the
circuit breaker off, install the sensor(s) and sensor
cables. Refer to the installation instructions provided
with each sensor. For greater system flexibility, it is
recommended to route the sensor cables through
conduit. If installing an extension onto the sensor
cable(s), a junction box is required in accordance with
applicable codes. Feed the sensor cable through the
weather-tight connection ports on the right side of
the control box, then connect the leads to the circuit
board terminals labeled RED, WHT, and BLK. If using
more than one sensor, it does not matter which sensor
goes to which set of terminals.
3. With the circuit breaker off, install the heat tape
(heater cables). Install the heat tape in accordance
with National Electrical Code (NEC) and heat tape
manufacturer’s specifications and requirements,
as well as other local and applicable building and
electrical codes and standards. If using a SIT–6E
pavement-mounted sensor, run the heat tape so it
doesn’t touch the SIT–6E cable. Refer to the schematic
diagram on this Installation Sheet. Route the heat
tape through conduit as directed by the heat tape
