2 Motor and Blower Preparation Module HK HV to HE onversion (2/10) This document will show you step by step instructions on converting a HV fancoil with a multi-speed motor to the HE style with a variable speed motor. The HE ontrol Board is programmed with multiple speeds and air flows controlled by the thermostat and dip set ranges for each style of blower. The ontrol Board converts the supplied single phase power of 100v-240v and converts the power to 3 phase motor and sends 3 phase power to the motor. The Heavy Duty 3 Phase Motor provides years of reliable service, as the heavy duty construction and power limiting function of the EP controller minimizes motor stress and wear. The new inverter drive technology offered by the EP Motor and ontroller reduces power consumption by up to 70%, with an average overall yearly reduction of 50% over standard PS motors. oise related to excess power input is eliminated.

3 Module HK HV to HE onversion (3/10) 1. Shut off electric power to the unit. HV Fan oil Preparation 2. Make note of the pump timer setting. abel all wires before disconnecting when servicing controls. Wiring errors can cause improper and dangerous operation. 3. Disconnect electrical power from the circuit board. 4. Disconnect motor connection and all thermostat wires, condensing unit, freeze stat, circulator, zone valve etc. It is not necessary to remove wires completely from the fan coil, it may be necessary to bring the wires into the new HE Electrical box before sliding the electrical box into place. 5. Remove existing HV ircuit Board Electrical box. 6. Remove mounted motor and blower. 7. arefully remove center plate trying not to damage the insulation lining in the unit. Depending on the clearance on the outside of the fan coil, it may be easier to cut the screws from inside, depending on the clearances around the unit.

4 Module HK HV to HE onversion (4/10) HE omponent Installation 8. Bend down the HV ontrol Box mounting metal tabs flat if located in fan coil. 9.Install new center plate, careful not to damage the insulation lining in the unit. 10. Replace screws. Depending on the clearance on the outside of the fan coil, it may be easier to replace the screws from the inside to out. 11. Install EP mounted motor and blower. 12. Install EP Electrical box and connect motor. (See next page) 12 Replace Screws Module HK - HV to HE onversion Kit Installation (4/10) Energy Saving Products td.

5 HE Electrical Box Installation Module HK HV to HE onversion (5/10) 13. Slide ontrol Box into fan coil allow the metal flange to clip onto the fan coil cabinet while the other side simply rests on the Fan oil cabinet. 14. Bring motor wires into control box, insert wires into plastic clip and insert plastic clip to protect the motor wires. Reconnect motor to the control board onnect motor ground to the electric board box Reconnect all thermostat wires, condensing unit, freeze stat, circulator, zone valve etc. hange pump timer setting and dip switch settings for the new board assembly. Reconnect electrical power to the board. 17. Replace door covers on fan coil and replace wiring sticker on the door. Write down on provided sticker the Model and Serial umber of the fan coil and stick to the bottom of old control box. Return to supplier.

9 The extended pin settings show how to increase or decrease the required FM on the Hi-Velocity-HE fan coil for fine tuning. The chart illustrates the FM difference achieved changing pins 6, 7, and 8. Only these three pins are modified to increase or decrease the FM based upon the selected tonnage of pins 1 through EP Dip Ranges & Extended Air Flow Adjustments EP Dip Ranges Module HK HV to HE onversion (9/10) FM output tons / 5.3 kw 2 tons / 7.0 kw 2.5 tons / 8.8 kw 3 tons / 10.6 kw 3.5 tons / 12.3 kw 4 tons / 14.1 kw 5 tons / 17.6 kw dip setting Extended Air Flow Adjustments The extended pin setting applies to all HE fancoils and can be used to lower or raise FM output.
