Automatic Pipe Freeze Protection Ca-
ble Installation and Operating
Instructions
For Metal and Plastic Pipes
This pipe freeze protection cable is
comprised of a heating cable, thermostat
and power cord and may only be used for
freeze protection of metal or plastic water
pipes up to 76 mm diameter.
Read carefully and follow these instruc-
tions for an efficient, economical and safe
installation. We recommend you retain
these instructions for future reference.
CAUTION
C1. The heating cable must not touch,
cross or overlap itself at any point.
This will cause the heating cable to
overheat.
C2. The heating cable cannot be altered in
length. If made shorter, it will overhe-
at and if made longer, it will produce
insufficient heat. Any attempt to phy-
sically alter the heating cable will void
the warranty. Once cut, the heating
cable cannot be repaired.
C3. If the heating cable is stiff (due to
cold), FIRST UNCOIL IT and then plug
it in for a few minutes until it is warm
and pliable before applying it to the
pipe. NEVER PLUG IN THE HEATING
CABLE WHILE IT IS COILED; this will
cause the cable to overheat where it
touches itself, and the outer jacketing
will melt and then fuse together upon
cooling.
C4. Do not install on pipes that are heated
to above 66°C (155°F) such as steam
lines; these high temperatures will da-
mage the cable.
C5. The heating cable must be spaced at
least 13 mm from any combustible
materials (including combustible insu-
lation) to ensure the prevention of
fire.
C6. NEVER use more then 13 mm of fib-
reglass or polyethylene foam insulati-
on. Overinsulating the heating cable
will cause it to overheat. Ensure that
insulation is flame retardant type.

C7. The heating cable must be protected
from physical abuse if it is installed in
locations where it may get damaged
(e.g. chewing by animals, debris from
lawnmowers, snow shovelling, falling
ice, etc.).
C8. Do not spiral heating cable; keep the
cable straight along the entire length
of pipe.
C9. The heating cable must not be im-
mersed in any liquid.
CABLE AND INSULATION SELECTION
S1. Measure pipe length and diameter
S2. Select the cable closest in size to the
pipe length. The cable must be no less
then 600 mm shorter than the pipe,
and must not be any longer. It is pos-
sible to use two cables for one pipe
length and these cables may overlap
up to 600 mm if placed on opposite
sides of the pipe.
S3. Select the insulation to be applied
over the heating cable/pipe. Am maxi-
mum of 13 mm of insulation may be
used. Either foamed or mineral wool
insulation may be used. Ensure that
foam insulation is flame retardant ty-
pe.
INSTALLATION
I1. Prepare the pipe
Before applying the heating cable, en-
sure that the area on and around the
pipe is free and clear of sharp edges
and combustible materials (to mini-
mize the risk of damage to the cable
and adjacent areas).
I2. Apply aluminium foil to plastic pi-
pe
If you are applying the heating cable
to a plastic pipe, we recommend that
you first wrap the pipe with aluminum
foil before applying the heating cable.
The aluminum foil distributes the heat
from the heating cable uniformly
around the pipe, as aluminium is a
better heat conductor than plastic.
I3. Prepare power supply
Ensure that a properly earthed electri-
