INTRODUCTION The information contained in these instructions has been prepared to assist in the proper installation and operation of the auxiliary electric heaters. Improper installations, or installations not made in accordance with these instructions, can result in unsatisfactory operation and/or dangerous conditions, and are not covered by the unit warranty. READ these instructions prior to installation or operation of auxiliary electric heaters. CHECKING PRODUCT RECEIVED Upon receiving heaters, inspect them for any damage from shipment. Claims for damage should be filed immediately with the shipping company. CHECK heater kit model number to determine if it is the cor - rect one for your unit and is the model desired. WARNING: ONLY ELECTRIC HEATER KITS SUPPLIED BY THIS MANUFACTURER AS DESCRIBED IN THIS PUBLICA - TION HAVE BEEN DESIGNED, TESTED, AND HAVE NECES - SARY APPROVALS INCLUDING UNDERWRITERS LABORA - TORY (U.L.) AND CSA FOR USE WITH THIS UNIT. USE OF ANY OTHER MANUFACTURED ELECTRIC HEATERS IN - STALLED ON THE UNIT MAY CAUSE HAZARDOUS CONDI - TIONS RESULTING IN PROPERTY DAMAGE, FIRE, OR BODI - LY INJURY. POWER SUPPLY AND CONTROL CIRCUITS POWER SUPPLY CAUTION: When heaters are installed in a previously in - stalled basic unit, field supply conductors, supply circuit fuses or disconnects may need replacement due to the larger load requirements. All wiring should conform to the National Electrical Code as well as applicable local codes. The power supply wiring can be connected through one side of the heater control box. A conduit opening is supplied for the maximum wire size to be used with any unit. Use reducing washers for smaller conduit sizes. See the wiring diagram and the name plate on the heater for internal or supply circuit overcurrent protection. Either fuses or HACR circuit breakers may be used in the supply circuit. Only copper supply wiring may be used. WARNING: THE UNIT MUST BE ELECTRICALLY GROUNDED IN ACCORDANCE WITH LOCAL CODES OR THE NATIONAL ELECTRICAL CODE, ANSI/NFPA 70-1987. (C.E.C. in Canada) CONTROL SUPPLY The low voltage control supply is furnished from the con - densing unit low voltage terminal block. Factory provided #18 AWG pigtail leads are provided to be interconnected with the remote condensing unit and thermostat. Reference heater wiring diagram. THERMOSTAT Some thermostats, whether single or two-stage, have an ad - justable heat anticipator. For proper adjustment, add the current draw in amperes of all components controlled by the particular stage. Set the anticipator to this total. See the in - structions packed with the thermostat for specific information. Heat anticipator settings for heaters in this series should be.4 amperes for each stage on heaters rated 40 KW and less. APPLICATION The auxiliary electric resistance heater kits are designed for installation directly on the air handler discharge flange. All kits are installed in the blower discharge air flow. The clearance to combustible material of the heater is 1 inch and the first three (3) feet of duct is 1 inch. OPERATION The heater kits have an instant on/instant off control system. For heater kit capacity, see Table A. MOUNTING INSTRUCTIONS 1. WARNING: IF AIR HANDLER UNIT IS ALREADY INSTALLED, DISCONNECT ELECTRICAL POWER BEFORE HEATER KIT INSTALLATION. 2. Remove blower/motor access door (left hand door fac - ing blower discharge) which gives access to the blower motor J box. 3. An electrical knockout is provided on the blower discharge panel approximately 2 1 2 to the left side of the discharge duct flange. Remove this knockout and cut out the thermal insulation on the inside of the cabinet around the opening. 4. Mount the heater kit on the air handler duct flange with the heater control compartment located on the left hand side facing the blower discharge opening. Do not at - tempt to orient the heater in any other position.. Install the 3 long by 1 1 2 conduit nipple between the heater control compartment and the air handler through the hole noted in step No. 3. 6. Install two conduit lock nuts on the inside of both cabinets and the other two on the outside of both cabinets. Install the two plastic bushings on both ends of the conduit nipple. 7. Route the three blower motor leads from the blower motor contactor inside the heater kit through the conduit nipple to the blower motor J box inside the air handler. 8. Connect low voltage pigtail leads to appropriate thermostat terminals reference wiring diagram. 2

single leads of adequate size colored wire from ther - mostat subbase terminals through to heater kit low voltage pigtail leads. Do not short thermostat wires since this may blow fuse in control transformer. FIELD POWER SUPPLY CONNECTIONS TABLE SL FIELD 24 VOLT CONTROL WIRING CONNECTIONS FIGURE 2. WIRING GROUNDING WARNING: THE UNIT MUST BE ELECTRICALLY GROUND- ED IN ACCORDANCE WITH LOCAL CODES OR THE NA - TIONAL ELECTRIC CODE. ANSI/NFPA 70-1987. (C.E.C. in Canada) A grounding lug is provided near the power terminal block for a ground wire. Grounding may be accomplished by grounding the power line conduit to the heater kit and connecting the factory furnished conduit nipple between the heater kit and air handler. Make sure the conduit nut locking teeth have pierced the insulating paint film of the blower panel. CONTROL WIRING (CLASS II) Low voltage control wiring should not be run in conduit with power wiring, unless Class 1 wire of proper voltage rating is used. Route thermostat cable or equivalent THERMOSTAT A two-stage heating thermostat with matching switching sub-base may be ordered as an accessory. Thermostats are available in either automatic or manual changeover. The ther - mostat should be mounted on an inside wall about five feet above the floor in a location where it will not be affected by the sun, or drafts from open doors or other sources. Install level; and after installation, check the thermostat calibration and recalibrate if necessary. ELECTRIC HEAT Heat anticipator settings on heaters should be.4 amps for each stage. WARNING: AFTER COMPLETION OF WIRING, CHECK ALL ELECTRICAL CONNECTIONS, INCLUDING FACTORY WIRING WITHIN THE UNIT, AND MAKE SURE ALL CONNECTIONS ARE TIGHT. REPLACE AND SECURE ALL ELECTRICAL BOX COVERS AND ACCESS DOORS BEFORE LEAVING UNIT OR TURNING ON POWER TO CIRCUIT SUPPLYING UNIT. WARNING: ONLY ELECTRIC HEATER KITS SUPPLIED BY THIS MANUFACTURER AS DESCRIBED IN THIS PUBLICATION HAVE BEEN DESIGNED, TESTED, AND EVALUATED BY A NATIONAL- LY RECOGNIZED SAFETY TESTING AGENCY FOR USE WITH THIS UNIT. USE OF ANY OTHER MANUFACTURED ELECTRIC HEATERS INSTALLED WITHIN THE UNIT MAY CAUSE HAZAR - DOUS CONDITIONS RESULTING IN PROPERTY DAMAGE, FIRE, OR BODILY INJURY. 8
SERVICE HEATER CONTACTOR (HC) The contactors are magnetic type. They have low voltage (24V) coils and are controlled directly by the thermostat. LIMIT CONTROL Limit controls are located in the element mounting plate of the elements. These controls are automatic reset types which prevent the unit from overheating in case of a malfunction. If replace- ment becomes necessary, they must be replaced with the same type and same temperature specification. LINE LIMITS (LL) The line limits are wired into the beginning of each element as a back up protection to a malfunction of the low voltage limit control. These controls are non-resettable and must be replaced if they should ever function. Replacements must be the same type and temperature ratings as originally supplied by the factory. FIGURE 3.
