General Introduction

Drexma heating cable was designed and manufactured only for the purpose of preventing water pipes tram freezing. lmproper or wrong installation, use and/or maintenance of electrical heating cable will cause fire, electric shock and/or freezing of pipe,

• These instructions must be saved and transferred to the owner and any future owner. Before starting, be sure you have selected the correct length heating cab le for the pipe to be protected, see 2.Gable Length Recommendation.
• Ater reading the following instructions, if you still have questions regarding installation or operation of the heating cable, please contact your d istributor.
• Heating cables must be installed in compliance with all National, State or Provincial and Local Codes. Check with your local electrical inspector for the specific details.

General Installation Instructions

Impotant: Tools and materials required Materlals:

• 1/2-in. fiberglas or equivalent non-lammable pipe insulation with vapor seal

Tools:
Scissors·Tape measure·File·Making•pencil·EYe protection
Electric Pipe Heating Cable on Metal Water Pipe

WARNING: During installation always wear safety

• Before applying the heating cable, make sure that the area and around the pipe is free and clear of sharp edges and combustible mate rials.
  Remove old heat tapes before proceeding and use a file to remove any sharp edges.
  Make sure there is a properly grounded electrical receptacle close enough to plug in the cable. We strongly recommend the use of a GFCI protected circuit. Use on 120 volts and make sure the electrical oullet is not overloaded.

• Choose the right length of freeze protection cable before installation and plan the routing of the heating cable on the pipe. The thermostat (the splice or end of the heating cable) must be placed tightly against the pipe and secured with good quality electrical tape.

• The thermostat should be placed on coldest end of the pipe to turn the cable on or off, for an energy saving operation.

• Apply good quality electrical tape at 15 cm intervals to secure the heating cable straight along the pipe. Minimum heating cable bend radius is 1 inch.

• The lowest installation temperature of this heating cable is -10°C. Never install the heating cable when the cable is lower than this temperature. If heating cable is stiff(due to cold), first uncoil it and then plug it into the rated voltage(120V) outlet until it is warm and pliable before unplugging it and applying it to the pipe.

WARNING: Never install heaing cable on plastic pipe unless pipe is filled with water an the lime. Use plastic(including PEX tubing) piping material suitable for residential water applications. ln order to obtain even heat distribution, we recommend wrapping plastic pipes with aluminum foil before applying the heallng cable.

• Attach the cable ta pipe in straight, spiraling or multiple tracing. If there is any excess cable remaining at the end of the pipe, you can double back along the pipe.
• Use the minimum 1/2″(12.7mm) thick fiberglass insulation or equivalent thermal insulation materials to caver the whole pipe, connections, valves, joins, wall penetrations and so on.

WARNING: If the ambient temperature is lower than -20°F(-29°C), please use 1″ thick insulation material. The thermal insulation must be waterproofed(with polyethylene or other vapor barriers) in areas where water may come in and contact with the insulation materials. Please use the fire- resistant materials such as preformed foam or fiberglass.

WARNING: Always use good quality electrical tape with a minimum of 176°F(80°C) temperature rating. Other adhesive tapes may allow the cable to move or shift at normal cable operating temperatures and could result in overheating, fire or electrical shock.
Based on diameter and length of standard pipes, we recommend cable lengths according to the following table.

CABLE LENGTH CALCULATION AND RECOMMENDATION

Based on the diameter and length of standard pipes, we recommend cable lengths according to the following table.

You can use the number in the above chart to multiply the length of your pipe to pickup the right products. For example, if your pipe is metal, the length is 20ft, the diameter of your pipe is 1″ anl the lowest ambient temperature is -20°F in your area, you will find the “1.3”based on the chart. Vou can use 20ft x 1.3 = 26ft. You can choose our 30ft JHSF preassemble heating cable (Pick the length wich is close to the number which you calculatel).
JHSF can be installed straight along the pipe for some small pipes. At lower temperatures, for longer pipes, the cable needs to be installed by spiral to ensure the pipe can get the adequate heat from the cable to avoil the freezing.

NOTE: For each valve or spigot on pipe an additional foot of the cable is needed. When the cab le is longer than the pipe, spiral the excess cable around the pipe length evenly.

• Check the length of the cable and the pipe. If they are the same, run il straight along the bottom of horizontal pipes and “weather side” of vertical pipes(including valves).
• When using 2 cables, put them in 4 o’clock and 8 o’clock positions. If three heating cables are needed, put them in the 11 o’clock or 1 o’clock position and 4 o’clock and 8 o’clock positions. Vou can check the figure 1. for the details.
•  If the cable is longer than the pipe and less than double the pipe length. Vou can spiral he cable over the length of the pipe. Vou can suspend a loop by every 1 0 feet as in Figure 2. Vou can define the loop length (divide the Drexma cable length by your pipe lengh and multiply by 10). Here is an example: The length of the cable you will use is 60ft and the pipe length is 40ft. Vou can leave a 15-foot loop of heating cable at evey 10-foot section of the pipe. Hold the center position of the loop and wrap the loop around the pipe. Vou can slide the wraps along the pipe to make the loop distances even. Secure the center of the loop to the pipe by he glass tapes. Vou can check the figure 2 for the details.
• If there is any excess cable remaining al the end of the pipe, you can double back along the pipe.
• Cable will protect pipes up to 1-112 in. in diameter.

WARNING: Please strictly follow he below nine poins. Failure cou Id cause overheating and result in serious tire hazard or electrical shock.

•  Never install to avoid external heat sources which might overheat installation. Do not use heating cable on pipes heated above 140°F(60 °C) , such as steam lin es.

• Never alter or eut the length of the heating cable in any way.
  Any alteration may result in electrical shock or fire.

• The thermostat and the entire heating cab le has to be in contact with the pipe.

• Never use matai binding to secure heaing cable to pipe.

• Never use with indoor pipes. Gable should not run through the building walls, ceilings or floors.

• Cable are intended for freeze protection of water pipes only. Never use with oher liquids or hazardous materials.

• For installation in accessible areas only.

• Not for use with an extension cord.

• Never use on flei<ible vinyl tubing(such as garden hases).

MAINTENANCE

• At the beginning of the heaing season and monthly during operation, inspect the eating cable and ils connection to the electric power source.
  llscontlnue use and remove any unit tnat has leen eut, damaged, lmmersed ln water, shows any evldence of charrlng or crac.lng, or has deterloratel for any reason. Other condiions to look for are chewing by animais, debris thrown from lawnmower or any physical abuse. This cable does not contain anv serviceable pats.

• Heating cable may remain on he pipe year round, but we suggest always turning of or disconnecing the power at the end of the season (when air tempe ratures remain above 10 °C). The thermosat turns the heating cable on when exposed to temperatures below 3 °C. lt will shut the heating cable off when the pipe has been heated to a temperature of approximately 10 °c.
