Kit COntEntS

This product is designed for use as a heater on air conditioning and refrigeration metal compressors up to 107 cm (42 in) in
circumference in ordinary (non-hazardous) locations. The product is intended to warm the compressor casing to facilitate
"cold start-up" conditions.
The cable consists of a heating section and a non-heating cold lead for connection to power supply in a junction box.
Read the entire instruction sheet before starting the installation. The cable must be installed by a qualified HVAC/refrigeration technician
and/or an electrician.

WARninGS!

Heating cables must be installed in compliance with all national, state, provincial, and local electrical codes.
a
These instructions must be retained and made available to the user and transferred to future users.
It is recommended that the circuit supplying the heating cable have ground fault protection; this is mandatory by electrical code
for some applications in many regions. Consult an electrical inspector to determine the specific ground fault requirements for your
application prior to installation. If you are unsure that your circuit has ground fault protection, consult an electrician.
Do not alter the length of the heating cable – the cable is factory sealed and alteration will result in risk of fire or electrical shock.
Post warning labels supplied with the cable to the power supply disconnect switch and in the area of installation.
Due to the cable's oval shape and flexibility, it is intended to be coiled only with the flat side of the cable against the compressor to
provide appropriate heat transfer. Do not bend tighter than a 8 cm (3 in) diameter as this will damage the heating cable and result in
reduced heat output.
Do not expose the cable to temperatures above 66°C (150°F): Degradation of the heating cable will result. Minimum installation
temperature for the heating cable set is 0°C (32°F) – installation at lower temperatures will damage the cable and result in fire or
shock hazard.
Do not use this cable for other applications, such as pipe freeze protection or roof de-icing; the cable is not designed for these
applications and fire, shock, injury or death may occur.

inStALLAtiOn

Before installing the heating cable, ensure the compressor surface is clean and free of any sharp edges that may damage the heating cable.
For best heating, the heating cable must be installed with the printing visible to the outside. Spiral the heating cable flat in good contact
against the compressor around the bottom-to-lower third of the compressor at a uniform spacing such that it does not overlap itself (to
facilitate optimum heat transfer). If necessary, however, the cable may touch or overlap itself without being damaged.
Insert the cable tie into its clip and in a secure and snug manner. Do not tighten more than 6.8 kilograms-force (15 pounds-force) or
else the cable tie will come away from cable and result in poor securement. (Once the cable tie engages the ribs, the tie will securely
hold the cable in place.) The cable tie may overlap the heating cable (see Figure 1 on page 2).
