HEATING CABLE INSTALLATION

1.

Determine the total amount of heating cable needed for the heating system. Refer to Table 1. Add heating cable for leads, gutters, downspouts, etc. Typical lead allowance is 3 ft per power connection.

2.

Determine the total power needed for the heating system by multiplying the total amount of heating cable by the design load (Amp/ft). See Table 2.

3.

Determine the maximum circuit lengths, based on the circuit breaker size, start-up temperature of 0°F, cable type, and voltage (see Table 2). Based on the maximum circuit length, lay out the heating cable into circuits.

5.

From the RIM2 System Layout drawings, if provided, review circuit routing and locate end seals. Install the heating cable end seal per the included end seal kit installation instructions.

6.

Beginning at the end seal location, position the GM heating cable into the RIM2 bases (2 runs in RIM2-E base; 2 runs in RIM2-LPE, RIM-S and RIM2-V bases; 1 run for gutters and downspouts) unless otherwise specified in the RIM2 System Layout drawings.

7.

Allow enough heating cable to make the connection to the junction box. If cable splices are needed, allow sufficient cable at splice locations and complete using the splice kit installation instructions. Splices are best located in gutters and at eave ends, not at valleys or in cable cover brackets.

Caution:

WARNING: Be careful not to permeate the cable jacket with staples or nails, or to route the heating cable over sharp edges that could damage the heating cable jacket over time.

10. To complete the power connection, refer to the power connection kit installation instructions.

11. Verify heating cable is not connected to power source. Prior to installing RIM2 cover panels, test the electrical insulation resistance of the heating cable. Use an appropriate megohmmeter set at 500, 1000, and 2500 Vdc. Record results on Log Sheet.




Phone: +1.916.933.5666 / Fax: +1.916.933.5959

INSULATION RESISTANCE TEST (MEGOHMMETER) TEST

Frequency

Insulation resistance testing is recommended at four stages during the installation process and as part of regularly scheduled maintenance.

• When received

• After the cables have been installed

• Prior to initial start-up (commissioning)

• As part of the regular system inspection

• After any maintenance or repair work

* Under adverse weather conditions, or when the tails or terminal connections have evidence of moisture, lower insulation resistances may be encountered. Wipe tails, face of pot, and all terminal connections with a clean dry rag to eliminate moisture and retest.

Test Criteria

The minimum insulation resistance for a clean, dry, properly installed circuit should reflect the values shown above, regardless of the heating cable length. The insulation resistance test is critical to ensure the safety and reliability of the heating cable system. This test should be performed as part of the installation of the system, and is useful for troubleshooting an installed system.

WARNING: Shock or Fire Hazard. Disconnect power to all circuits prior to testing.

Using a megohmmeter, test insulation resistance at three voltages—500, 1000, and 2500 Vdc.

Significant problems may not be detected if the insulation resistance is tested only at 500 or

1000 volts. First, measure the resistance between the heating cable bus wires and the

Grounding braid; then, if the heating cable is installed on a metal gutter, downspout, and/or metal roof, measure the insulation resistance between the braid and the metal surface.

Procedure

1. Disconnect all power to the heating cable, thermostat, and contactor.

2. Set test voltage at 0 Vdc.

3. Connect the negative lead (–) to the heating cable metallic braid.




Phone: +1.916.933.5666 / Fax: +1.916.933.5959

4. Connect the positive lead (+) to both heating cable bus wires.

5. Turn on the megohmmeter and set the voltage to 500 Vdc; apply the voltage for 1 minute.

Record the resistance.

6. Repeat step 5 at 1000 Vdc and 2500 Vdc.

7. Turn off the megohmmeter.

8. If the megohmmeter does not self-discharge, discharge phase connection to ground with a suitable grounding rod. Disconnect the megohmmeter.

9. If the heating cable is installed on a metal roof, metal gutter, or metal downspout, repeat these steps with the negative lead (–) connected to the grounding braid and the positive lead

(+) connected to the metal roof, gutter, and/or downspout.

10. Reconnect the thermostat or contactor and reenergize the circuit.

Insulation Resistance Criteria

A clean, dry, properly installed circuit should measure thousands of megohms, regardless of the heating cable length or measuring voltage (0–2500 Vdc). The following criteria are provided to assist in determining the acceptability of an installation where optimum conditions may not apply:

• All three insulation resistance values should be greater than 100 megohms.

• Insulation resistance values for any particular circuit should not vary more than 25 percent as a function of measuring voltage.

• Reading must be steady at measuring voltage.

• If any of the above conditions are not met, consult the “Troubleshooting” instructions.

RIM2 SYSTEM OPERATION PROCEDURES

General Description

The Raychem Roof Ice Melt System is designed to prevent ice dams at eaves and in valleys and to prevent icicle formation at the eaves. The system accomplishes this by providing heated eave panels that keep melted snow from refreezing as it drains off the eave, and by providing heated valley panels that ensure a continuous water drain path down the valley.

Fall Testing

Some time prior to the winter season, test each circuit by turning on each circuit breaker, one at a time, and leaving them on for 10-15 minutes. Should any of the circuit breakers trip, reset the circuit breaker for a second test. If the circuit breaker trips again, refer to the “RIM System Troubleshooting” section of this manual.

If the heaters are controlled with an AS-Digital or Manual/Auto Control System (MACS) it is not necessary to wait until the ambient temperature is below freezing. Set the Heater-On set point several degrees above the currently sensed ambient temperature to energize any control zone that is set to

Auto via its 3-position switch. Or, use the 3-position switch to set the control zone to Hand (On). Once testing is complete, reset the Heater-On set point back to its original value or the switch to its original position.

If the heaters are controlled with a High-Efficiency Control System (HECS) it is not necessary to wait until the ambient temperature is below freezing. Set the controller's Heater-On set point several degrees above the currently sensed ambient temperature so that the Control Zone temperature controllers will be energized. Once the Control Zone temperature controllers are energized the RIM panel maintain temperature (lower number on the controller) can be raised above the current RIM panel temperature

(upper number on the controller) in order to energize the heaters (see High-Efficiency Control System

Setup and Operation). Once testing is complete reset the panel maintain temperature back to its original value (factory default setting is 42°F).

Winter Startup

At the onset of snow accumulation on the roof surface, energize the RIM panels by turning on the circuit breakers (typically in November/December). RIM systems controlled with an AS-Digital or Manual/Auto

Control System (MACS) will be energized when the ambient temperature falls below the Heater-On set point on the ambient sensing controller AND the 3-position switch is set to Auto, or when the 3-position switch is set to Hand (On). RIM systems controlled with a High-Efficiency Control System (HECS) will be energized when the ambient temperature falls below the Heater-On set point AND the RIM panel temperature (upper number on the Control Zone temperature controllers) is below the specified RIM panel maintain temperature (lower number on the Control Zone temperature controllers).

Unusual Winter Conditions

Most winters start up with gradual snow accumulation on the roof in November/December and the snow accumulation remains until March/April. Sometimes, however, the snow either melts or slides off roof sections and those sections remain without snow until the next snowstorm. The owner, at his option, may choose to de-energize those sections.

For RIM systems controlled with an AS-Digital Controller or Manual/Auto Control System (MACS), set the controller’s 3-position control zone switch to Off only for those sections without snow (the owner must remember to set the ambient controller’s Run/Stop Mode back to RUN or to turn the 3-position control zone switches back to Hand (On) or Auto when the next snowfall occurs).

For RIM systems controlled with a High-Efficiency Control System (HECS), set the 3-position control zone switch to Off only for those sections without snow (the owner must remember to set the ambient controller’s Run/Stop Mode back to RUN, or to turn the 3-position control zone switches back to Hand

(On) or Auto when the next snowfall occurs).

Spring Shutdown

In the spring when the snow has melted off the roof surface, the owner should de-energize (turn circuit breakers off) the RIM System for the summer. As mentioned above, some roof sections (primarily south facing) can be de-energized before the balance of the roof sections (north facing and shaded areas).

Circuit breaker or ground fault protection device continues tripping.

Possible Cause

a. Circuit breaker and / or ground fault protection device turned off or tripped.

b. Interconnect wiring has open circuit.

c. Control system (by others) off or

Heater-On set point too low.

a. Short circuit in heating cable or wiring has occurred.

a. Turn on / reset.

b. Check continuity of wiring and all connections.

Check all splices in junction boxes.

c. Turn system on, adjust Heater-On set point. If problem persists, check with manufacturer.

Disconnect the power wires from circuit breaker and perform 1000V insulation (megger) test of the wiring at the circuit breaker

Bylin drawing S-MGR-001, Heating Cable

Insulation Test. If the megger test passes, proceed to Step “b”.

If insulation test fails at the power wiring, perform test on heating cable at local junction box by disconnecting power wires from heating cable (for multiple heater cable runs on same circuit, test each run separately).

If insulation test passes for each heating cable run, test power wiring. If insulation test fails for power wiring, fix or replace wiring until wiring passes test.

If insulation test fails for a run of heating cable, check for moisture in junction box, damage to the heating cable, or improper power connection, splice or end seal installation.

Repair or replace heating cable and components using Bylin approved materials. Retest.

Properly installed end seal will show a narrowing at the end b. Ground fault protection device rating is too low (e.g., 5mA).

c. Defective ground fault protection device.


End Seal b. Replace with 30mA EPD (Equipment Protection

Device) ground fault protection device.

c. Replace ground fault protection device as required.
