CONTRACTOR SHALL PROVIDE A COMPLETE PIPE HEAT TRACE SYSTEM FOR ALL DESIGNATED PIPING AS SHOWN ON MECHANICAL DRAWINGS AND IN HEAT TRACE TABLE (THIS SHEET). CHILLED WATER, TOWER WATER, EQUALIZER PIPING, AND NPCW HEAT TRACE SYSTEMS SHALL BE A SELF REGULATING HEAT TRACE CABLE. EACH CIRCUIT SHALL BE CONNECTED TO A 20A-1P BREAKER (SEE ELECTRICAL DRAWINGS). HEAT TRACE CABLE SHALL PREVENT FREEZING OF PIPES DOWN TO A MINIMUM AMBIENT TEMPERATURE OF -20°F. ALL CABLE SHALL BE RATED AT 277V. CHILLED WATER, TOWER WATER, EQUALIZER, AND NPCW CABLE SHALL BE CONTROLLED BY AN EXTERIOR THERMOSTAT WITH A 40°F ACTIVATION TEMPERATURE. CONTROL PANEL SHALL HAVE INTEGRAL GROUND FAULT EQUIPMENT PROTECTION FOR HEAT TRACE CIRCUITS. INSTALL ALL HEAT TRACE CABLE IN ACCORDANCE WITH MANUFACTURER'S INSTALLATION

INSTRUCTIONS. HEAT TRACE SHALL BE TESTED AT THE FOLLOWING TIMES:

1. UPON RECEIPT OF HEAT TRACE COMPONENTS, PRIOR TO INSTALLATION.

2. UPON COMPLETION OF INSTALLATION ON PIPE, PRIOR TO INSULATION.

3. UPON COMPLETION OF PIPE INSULATION.

HEAT TRACE TABLE

THE FOLLOWING IS PROVIDED AS GENERAL GUIDELINES, CONTRACTOR SHALL ALSO REFER TO

MANUFACTURER'S INSTALLATION REQUIREMENTS.

1. INSTALL HEAT TRACE CABLE AT EITHER 8 O'CLOCK OR 4 O'CLOCK ON THE PIPE SURFACE.

2. FOR PIPE ELBOWS INSTALL HEAT TRACE CABLE ON THE OUTER RADIUS.

3. AT PIPE COUPLINGS, HEAT TRACE CABLE SHALL BE INSTALLED BENEATH THE COUPLING BOLT AND

SHALL NOT BE INSTALLED ON THE OUTSIDE OF PIPE COUPLING BOLT.

4. HEAT TRACE CABLE SHALL BE SECURED TO PIPING AND FITTINGS WITH HIGH TEMPERATURE ADHESIVE TAPE TO ENSURE HEAT TRACE CABLE IS IN CONTINUOUS CONTACT WITH PIPING AND

FITTINGS.

5. CONTRACTOR SHALL TEST HEAT TRACE PRIOR TO FILLING EACH SYSTEM.

6. CONTRACTOR SHALL WORK WITH VA COR TO SCHEDULE INSPECTION OF HEAT TRACE

CABLE INSTALLATION WITH ENGINEER AND MANUFACTURER'S REPRESENTATIVE. ALL HEAT

TRACE SHALL BE INSPECTED DURING ONE SITE VISIT.
