Frost Protection Heat Tapes
INSTALLATION AND OPERATING INSTRUCTIONS
IMPORTANT: BEFORE UNPACKING
THIS PRODUCT ENSURE THAT THE INTENDED USEAGE IS FOR FROST
PROTECTION PURPOSES ONLY.
YOU RETAIN THE INSTRUCTIONS FOR THE CUSTOMER'S/OPERATOR'S
1) Before applying
the heat tape, make sure that the area on and around the pipe
is free and clear of sharp edges and combustible materials.
2) Apply the heat
tape to your pipe, either straight along or spiralled as necessary
according to the table. Secure the heat tape with electrical
tape (PVC) at intervals of not more than 200mm (8 inch).
3) For plastic pipes
apply a layer of aluminium tape (AL50) between the pipe and
the tape, including the thermostat to improve heat transfer.
4) When spiralled
around the pipe the heat tape must be evenly spaced over the
length of the pipe and the ENTIRE HEAT TAPE MUST BE USED:
EXCESS HEAT TAPE CANNOT BE CROSSED BACK OVER ITSELF, BE LEFT
COILED, OR BE LEFT HANGING OFF THE PIPE. SPIRALS MUST NOT
BE CLOSER THAN 25mm (I inch). DO NOT CUT THE HEATING TAPE.
5) Make sure that
electrical connections are made in accordance with the appropriate
regulations by a qualified electrician. Usually a suitable
fused spur connection is employed.
Ensure the heat tape is connected to the correct voltage
supply following the colour code Green or Green/Yellow to
the terminal marked with the letter E and/or the earth symbol
Blue wire to terminal marked with the letter N or coloured
Black. Brown wire to the terminal marked with letter L or
coloured Red. In some cases with the 110 volt cables the White
is neutral and the Black live.
6) The thermostat (the black cap in the moulded block)
must be placed tightly against the pipe and secured with electrical
tape. The thermostat should be placed on the coldest end of
the pipe. The thermostat will sense the temperature of the
pipe and turn the cable on and off to provide economical operation.
7) MAXIMUM 25mm (I inch) insulation should be used
over the heat tape. IT MUST ALSO BE APPLIED OVER THE THERMOSTAT.
Insulation must be protected with an additional waterproof
overwrap if the pipe is exposed to the weather.
8) The thermostat turns the heat tape on when exposed
to temperatures below 3ºC. It will shut the heat tape off
when the pipe has been heated to a temperature several degrees
9) For multiple tape installation an over-riding froststat
is recommended to switch off the complete installation as
the air temperature rises, thus conserving energy. FST-IN
or FST-EX is recommended.
1) The heat tape must not touch, cross or overlap
itself at any point. This will cause the heat tape to overheat.
2) The heat tape cannot be altered in length. Any
attempt to physically alter the heat tape will void the warranty.
Once cut, the heat tape cannot be repaired.
3) If the heat tape is stiff (due to the cold), first
UNCOIL it then connect it to the rated supply until it is
warm and pliable before applying it to the pipe. NEVER
CONNECT THE HEAT TAPE WHEN IT IS COILED.
4) Do not install on pipes that are heated above 66
C (155 F), such as steam lines.
5) The heat tape MUST
be spaced at least 13mm (½ inch) from any combustible materials.
6) NEVER use more than 20mm of fibreglass or polyurethane
foam insulation. Over insulating can cause the heat tape itself
to overheat, even with a properly installed thermostat.
7) The heat tape must protected from physical abuse,
if it is applied in locations where it is likely to be damaged
(e.g. chewing by animals, debris thrown from lawn mowers etc.).
If insulation is fitted to current water bye law requirements,
PGE Frost Protection Heat Tapes can be installed straight
along the pipe to frost protect up to a 100mm (4 inch) pipe
to -20 C. For lower temperatures or larger pipes consult factory.
The length of tape selected must therefore be equivalent
to or greater than the length of pipe to be protected. Excess
length is lost by evenly spiralling along the pipe.
1) To frost protect a 25mm pipe 18 metres long, fully
insulated with 25mm of insulation to -10.C use PGE-18, 18
2) To frost protect a 50mm pipe 32 metres long, fully
insulated with 25mm of insulation to -20.C use PGE-36, spiralled
to approx 0.8 turn per metre.
Use table 1 to determine the required watts per
metre (note PGE tapes will not provide adequeate pipe
freeze protection without insulation). Select a tape from
tables 2,3 and 4 with an output greater than or equal to that
required and suited to the length of the pipe and voltage
PGE tapes are generally applied
in a straight line along the length of the pipe. However,
if an output greater than 17 or 23 watts per metre is required,
this can be achieved by evenly spiralling the tape along the
length of the pipe. Use the following formula to determine
the required number of turns.
|Approx turns per metre=
||320 x (Tape length (m) - Pipe length
|Pipe length (m) x Pipe diameter (mm)

For plastic pipes apply aluminium
tape between pipe and heat tape Part No. TL AL50 (50m roll).
For multiple tape installations, an overriding frost-stat
is recommended to switch off the complete installation as
the air temperature rises, thus conserving energy. Internal
and external units available (FST-IN, TS WS10).
