NOTE: Read the entire instruction manual before starting the installation. This symbol indicates a change since the last issue. SAFETY CONSIDERATIONS Installing and servicing air conditioning equipment can be hazardous due to system pressures, electrical components, and fuel gases. Only trained and qualified personnel should install, service, or repair air conditioning equipment. Untrained personnel can perform basic maintenance functions such as cleaning coils, or cleaning and replacing filters. All other operations should be performed by trained service personnel. When working on air conditioning equipment, observe precautions in the literature, on tags, and on labels attached to the unit. Recognize safety information. This is the safety-alert symbol. When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury. Understand the signal words DANGER, WARNING, and CAU- TION. These words are used with the safety-alert symbol. DAN- GER identifies the most serious hazards which will result in serious injury or death. WARNING signifies a hazard which could result in serious injury or death. CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation. Follow all safety codes. Wear safety glasses and work gloves. Have a fire extinguisher available. Before proceeding with heater installation, inspect thoroughly for shipping damage. Notify shipper immediately if any damage is found. Clean all dirt, dust and moisture from heater package. Check for proper clearances of live parts, between phases and to ground. Make sure that all required barriers are in place. Check conductors run in multiple to insure that they are properly wired. Refer to unit installation instructions for complete unit installation details. The minimum air quantity for safe electric heater operation is shown in Table. Before performing installation, service or maintenance operations on this system turn off all main power switches and/or disconnects. There may be more than one switch or disconnect. Turn off accessory heater power switch if applicable. Electrical shock can cause serious injury or death. TAG DISCONNECT SWITCH(S) WITH A SUITABLE WARNING LABEL. INTRODUCTION This electric heater series is engineered, designed and listed to be installed only in the models shown in Table 1. Before proceeding, verify the heater label for correct voltage and kw requirements. Small Packaged Products 1-1/ to 5 Tons Accessory Electric Heaters Installation Instructions Electric Heaters 5 0 kw Cancels: New DESCRIPTION AND USAGE These SPP Electric heaters are to be used per Table 1 in SPP Electric Cooling & Electric Heat Pump units.

Open all electrical disconnects and install lock-out tag before beginning any installation or service work.. Verify that unit duct work is installed per base unit instructions. 3. Remove top cover of the unit to access heater compartment (See Fig. 1). 4. Check proper equipment model number from list. 5. Locate and remove the heater knockout plate in the indoor blower housing (See Fig. 1). 6. Remove electric heater from the packaging. Route control and heater high voltage wire through knockout as shown in Fig. 1. 7. Install heater, sliding assembly carefully into heater area in the blower housing (See Fig. 1). Ensure that mounting holes of heater align with mounting holes on the unit. Secure heater assembly with screws provided. 8. Dress wires with wire ties provided. Route heater wires along existing unit wire bundles behind and away from capacitors. 9. Fused Units: Remove fuse links of the fuse block, attach fuse block with screws () on mounting holes provided and re-install the fuse links. Attach lid to unit panel with (4) screws provided. Align with existing mounting holes (See Fig. 1). 10. Non-Fused Units: Adhere schematic in lieu of fused block inside unit panel (See Fig. ). 11. Install ground lug in mounting hole provided adjacent to -v. compartment (See Fig. ). ELECTRICAL CONNECTION 1. Open all electrical disconnects and install lock-out tag before beginning any installation or service work.. All electrical connections, wire sizes and type of conduit shall meet the National Electric Code and State and Local Codes. Main power supply, minimum wire sizes, circuits, fusing, etc. is shown on schematic wiring diagrams. NOTE: Use minimum 75 C copper wire only. 3. Refer to base unit instructions for recommended wiring procedures. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Connect low voltage wires as shown in heater schematic diagrams (See Figs. 5-). These connections must be made in the -v. barrier section inside the unit panel (See Fig. ). 5. Connect field power wiring as shown in heater wiring diagram. All connections should be made inside the unit and comply with the National Electric Code and State and Local Codes. Heaters with factory installed fuses may be installed on a branch circuit protected by either a fuse or circuit breaker. For all other heaters, the branch circuit must be protected by a fuse or a circuit breaker supplied by others. 6. Make all high voltage wire splice connections inside the unit control box (See Figs. 5-). Use splice connectors provided. Properly insulate connectors. Separate all wires from incoming power leads. 7. Be sure that all electrical terminal connections, clamps, screws, etc. are tight before proceeding. 8. Check wiring diagram supplied with heater for specific connections and information. 9. Check operation as described in Start-Up section. Before performing installation, service or maintenance operations on this system turn off all main power switches and/or disconnects. There may be more than one switch or disconnect. Turn off accessory heater power switch if applicable. Electrical shock can cause serious injury or death. TAG DISCONNECT SWITCH(S) WITH A SUITABLE WARNING LABEL. START-UP Before proceeding, verify that all wiring is correct per factory approved schematic. Notify factory immediately of any discrepancies. 1. Refer to base unit installation instructions as required.. Check for loose terminal connections. 3. Check that all fuse and circuit breaker short circuit interrupting ratings are adequate. 4. Turn on unit and heater power. 5. Set thermostat to call for heat. 6. Check operation of heater. 7. Check that airflow across the heater is at or above the minimum recommended CFM requirement (See Table ). Adjust indoor blower heat speed as required. 8. Any modifications or repairs to this equipment without written permission from the factory will be done at the installer s own risk and expense. TROUBLESHOOTING 1. Fuses -Malfunction will interrupt power to the unit. Check for cause of failure, replace fuses.
