SM Series Electric Heat INTRODUCTION | 3 INTRODUCTION The SM series HK Series Heater package is designed for installation in the heat pump model published in this document. Do not install this heater kit in a heat pump not specified in this manual. Installation and servicing of this equipment can be hazardous due to system pressure and electrical components. Only trained and qualified personnel should install, repair, or service the equipment.
| Electric Heat Kit • • SM Series Electric Heat Adhesive back electrical data label Clear hardware accessory bag containing: • Heater element mounting 3/8 Philip-Hex screws (4 for each element bank) • Four Heater element cover mounting 3/8 Philip-Hex screws • Two electrical box mounting 3/8 Philip-Hex screws • Push in wire-ties • This installation manual For technical assistance contact your local distributor or Bosch Technical Support: Figure # 3 (954) 776-5471 or Bosch.Fhp.TechSupport@us.bosch.com.
SM Series Electric Heat Installation - Hardware | 5 5. Remove the heater collar cover plate(s). (Figure#8) Figure # 8 Figure # 6 [1] Heating element cover [2] Electric Heat control box INSTALLATION - HARDWARE 1. At Thermostat Turn system to “OFF” 2. Turn the main power to the heat pump to “OFF” at the unit’s disconnect switch or breaker panel. 6. In preparation for heater element installation orient the heating elements with thermal overloads (cutouts) are on the right side for VT & CF and top for HZ.
| Installation - Wiring SM Series Electric Heat Figure # 10 If only one heating element is being installed, install in into the position closest to the blower wheel. Remaining opening to be covered using (1) of the cover plates removed in step 5. Figure # 12 5kW-10kW (HK050-100) Control Box 8. Secure each insert(s) with four of the supplied sheet metal screws (Figure#11).
SM Series Electric Heat Installation - Wiring | 7 Ensure no wires are pinched between the metal parts 3. Connect red and black high voltage wires originating from Electric Heater control box to the Electric Heater elements as shown in Figure#18. Terminate Black wires labeled HLS at the thermal limits (cutouts) and Red wires labeled HT at the heater element connections.(Figure#17 ) Each wire is labeled for ease of identification. Reference wiring diagram on Pg13. Figure # 15 1.
| Installation - Wiring SM Series Electric Heat 6. On the wiring harness supplied with this kit identify J39 plug. (Figure#19) Figure # 19 7. Route J39 plug through the hole in the divider panel and mate the plug to the receiving connector P39 on the side of the electric heat control box. 8. Re-apply cork tape to the divider panel hole. 9. Route the other end of the harness (3 connector end) along the already installed blower harness, and terminate it at the unit electrical box (E-Box).
SM Series Electric Heat 11. Mate J19 plug originating from the electric heat control box (red and black wires) with P19 plug originating from blower harness at EBox.(Figure#24) When mating plugs, push both connectors together until they snap with a click. Installation - Wiring | 9 13. Route the two line voltage wires that derived from the P19 plug, these wires should be routed under the contactor along the bottom of the electrical box.
| Installation - Wiring SM Series Electric Heat 16. There should now be one plug left labeled P12 on the electric heat harness. Mate this plug to its counterpart plug already available on the left hand side of the e-box labeled J12.(Figure#29 & #30) Figure # 31 18. Remove (2) screws as shown. (Figure#32) Figure # 29 Figure # 32 19. Mount Heater Element cover to blower collar using (4) 3/8 Philip-Hex screws. (Figure#33) Figure # 30 17.
SM Series Electric Heat 20. Use push in wire ties to secure cables to cover and blower bracket.(Figure#34) Figure # 34 THERMOSTAT WIRE CONNECTIONS 1. Assure that two low voltage wires are available from the thermostat to make the “W1” and “EM” connections. If these wires are not located, they will need to be pulled and routed from the back of the thermostat to main thermostat connections on the electrical box or to the motor control board. 2.
