Emerson EASYHEAT PSR1006 Installation Instructions

PSR
Pipe and Roof Deicing Heating Cable

Installation Instructions

General Information

• PSR heating cable may be used to help prevent water pipes
from freezing or to help prevent the formation of ice dams
on roofs.
• PSR heating cable is suitable for use on metal and plastic
pipes (such as PVC or polybutylene) but not on flexible vinyl
tubing (such as garden hose).
• PSR heating cable is suitable for use in metallic and
nonmetallic gutters and downspouts.
• PSR heating cable is a self-regulating heating cable designed
to change its heat output as the surrounding temperature
changes. As the surrounding temperature increases, the
output of the PSR cable decreases.
• PSR heating cables feature a pilot light in the plug (120V
models only) to indicate when power is applied to the cable.
• PSR cable is suitable for shingle, slate, metal, wood and flat
roofs with either plastic or metal gutters/downspouts.
Precautions
1. Heating cables must be installed in compliance with all
national, state, provincial and local electrical codes. Check

with your local inspector for specific details.
2. These instructions must be retained and made available to the
user and transferred to future users.
3. Heating cables must not be energized in summer conditions; ensure
that all heating cables are de-energized during the summer.
4. 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.
5. Do not alter the length of the heating cable - cable is factory
sealed and alteration will result in risk of electrical fire or shock.
6. Post warning labels (supplied with cable) to power supply disconnect
switch, circuit breaker panel, outdoor receptacle and any other
appropriate locations, as applicable. Also post labels along any pipe
(on outside of insulation) on which the cable is installed.
7. Do not bend cable to a diameter less than 5 times the cable
diameter.
8. Installing cable on a roof below 32°F (0°C) may damage the
shingle if it is brittle.
9. Minimum installation temperature for the heating cable set is
-30°C (-22°F).

Planning
• Exposure to temperatures above 150°F (66°C) will shorten the
life of your cable. Before installing on hot water pipes, set the
water heater thermostat below 150°F (66°C).
• Remove any old heating tapes or insulation before installing
the new cable.
• Do not alter the length of the cable.
• Do not use thin 1/8" (3.18 mm) foil-backed foam insulation.
• If more than one heating cable is used on a single electrical
circuit please refer to the maximum heater length per circuit
breaker size chart. Check to make sure the total heating
cable length does not exceed the length specified in this
table.
Selection of heating cable. Select the appropriate cable length
from one of the two charts on next page. Cable may be up to
2 feet (60.96 cm) shorter than the pipe. Lengths assume lowest
ambient temperature is -20°F (-29°C), with a minimum of 1/2"
(12.7 mm) fiberglass insulation or equivalent. For protection to
-40°F (-40°C), use 1" (25.4 mm) fiberglass insulation. Note: Allow an
extra foot (30.48 cm) of heating cable for each valve.
