SRCCH-1 and SRCCH-2

Self Regulating Crankcase Heaters

GENERAL

SRCCH-1 and SRCCH-2 Self-Regulating Crankcase Heaters are supplied with flexible lock-strap and pre-stripped 28” cold leads for easy connection and hardwiring. These heaters are only to be used on up to 40” diameter compressors located in non-hazardous areas.

ELECTRIC SHOCK/FIRE HAZARD. Do not expose heater to temperatures above 150˚F.

INSTALLATION

Before installing the SRCCH-1 or SRCCH-2 heater, a megger test should be performed to check integrity of electrical insulation jacket of the heating cable.

To use the SRCCH-1 and SRCCH-2 heaters, wrap cable around crankcase and tighten the flexible lock-strap. Make certain to have good contact between the heater and the surface of the crankcase. Connect leads to GFCI protected circuit.

Use SRCCH-1 for 120V operation and SRCCH-2 for 208-277V operation.

MEGGER TESTING:

Megger testing should be performed before first use and periodi- cally thereafter. Unplug assembly. Using a 2500 Vdc megohmmeter (500 Vdc minimum), check the insulation resistance between the power leads (black and white clamped simultaneously) and the green ground lead. Reading should be at least 20 meg-ohms regardless of cable length.

ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing heating cable and accessories. A qualified person must perform installation and service of heating cable and accessories. Heating cable must be effectively grounded in accordance with the National Electrical Code. Failure to comply can result in personal injury or property damage.

If low reading occurs, cable and insulation should be inspected for signs of damage. DO NOT attempt to repair damaged heating cable. If physical damage is found, the entire unit should be replaced.
