When used with the HE-Z Series, the system modulates refrigerant flow and indoor air flow to precisely match output capacity to load. The ability to match output capacity to load results in superior energy performance not just at the ANSI/AHRI Standard test conditions but right through the entire operational range. Fixed speed and 2-staged condensing units are not well suited for constantly changing load requirements and multizone applications due to their inability to reduce capacity below 70%. These systems overcome the problem by running the indoor fan at high flow rates and dumping or bypassing excess air. This strategy wastes energy, reduces efficiencies and sacrifices comfort in exchange for a properly functioning system. The HVS Variable Speed Heat Pump in conjunction with the HE-Z Series Air Handler solves this ongoing issue. The outdoor unit (inverter) monitors indoor coil (evaporator) conditions to maintain a steady air off temperature. No matter the load or number of zones open, the Variable Speed Heat Pump will adjust refrigerant flow or capacity to match these everchanging conditions. HVS Location Selection · The outdoor unit must be installed level, in a properly supported outdoor location that is adequately ventilated. Avoid installing outdoor unit on walkways and patios. · Outdoor unit should be installed using the rubber vibration isolation feet that were supplied with the outdoor unit. · It is good practice to secure the outdoor unit to its footings or base. If unit is to sit on an equipment riser, stand or hanger, it must be properly secured. · Locate the outdoor unit as close as possible to the indoor unit. Ensure minimum and maximum lineset lengths meet the min/max length specifications on page 4. · Outdoor unit should be installed in a location that can maintain the clearances specified on page 3 to ensure proper airflow/heat exchange and maintenance space. · Must be elevated above the Annual Snow Accumulation Level or average snow fall depths. · Make sure the piping/lineset vertical height drops do not exceed the allowable value specified on page 4. · Locate the outdoor unit where the noise, vibration and outlet air does not disturb residence, occupants or neighbors. · Ensure the air inlet or outlet is not impeded and does not face strong/prevailing winds. 2 -2- © 1995-2024 Energy Saving Products Ltd. www.hi-velocity.com Module HVS Variable Speed Heat Pump Installation HVS Location Selection Cont'd · Avoid locating the outdoor unit in a location that is severely dirty, polluted, or contaminated (e.g. close to a dryer vent or under a tree) to avoid blockage of the heat exchanger. If it is, maintenance or cleaning may be needed more than bi-annually. · If the outdoor unit is installed under an overhang or in an encloser to protect it from direct sunlight, rain exposure, snow, or strong winds, ensure it still maintains the needed clearances and avoid roof driplines.

Ensure insulation covers the entire line set, including flare fittings & penetrations. · The Electronic Expansion Valve is internal to the HVS Variable Speed Heat Pump, therefore a TXV at the evaporator (indoor unit) is not needed. · Maximum pipe length for the HVS-24 is 164.5' (50 m), for the HVS-36 and HVS-60 is 213 ft (65 m). Lines must be sized correctly to ensure that pressure drops within the system are minimized. HVAC mechanics should refer to the pipe sizing table below prior to installation. · Minimum refrigerant pipe length is 16 ft (5 m). If going less than 16 ft, coil the additional copper pipe up in horizontal loops to ensure proper oil return. · Refrigeration grade copper tubing is the only tubing to be used. Fittings used for bends, elbow, `P' trap, `Y' piece, etc., must be of the wrought copper type and clean from dust, burrs, oil, etc. It is recommended that the tube is cut with a tube cutter and the entire ID is made the correct size with an expanding device after cutting. All joints in the piping must be clean and free from dust, burrs, oil, etc. · All joints must be silver soldered with at least 10% silver content.

IMPORTANT For the HVS-24 It is critical to use unshielded communication cable (14 AWG / 4 Conductor, stranded) when running the 1, 2 and 3 communication wires between the '24v Interface Kit' and the HVS-24 outdoor unit. For the HVS-36 & HVS-60 It is critical to use shielded cable (18 AWG / 4 Conductor) when running the S1 and S2 communication wires between the '24v Interface Kit' and the outdoor unit. See wiring diagrams for further details. · Ground shielding of cable at the condenser side and cap off opposite end with a wire nut or equivalent. · Use provided EMC magnetic ring. Wrap the communication wires around the ring twice at the `24v Interface Kit' side of the communication wires: EMC Magnetic Ring - HVS-24 Wrap the electric wires 1, 2 and 3 around the magnetic ring twice EMC Magnetic Ring - HVS-36 & HVS-60 Wrap the electric wires S1 and S2 ( P & Q & E ) around the magnetic ring twice · The outdoor unit and the interface panel both require 240v supply power and require surge protection in locations with power fluctuations or inconsistencies. NOTE: For HVS-24 the interface panel is provided with 240v via the outdoor unit. In this case, only the outdoor unit requires surge protection. For HVS-36 and HVS-60 the interface panel and outdoor unit require separate power supplies. In this case, both need to be surge protected. · The interface requires 24v from indoor unit (R & C). · One temperature sensor is supplied with the interface panel which connects to T1 on the interface panel. This temperature sensor will need to be installed for the unit to operate properly and should be securely installed in the return air ductwork. 6 -6- © 1995-2024 Energy Saving Products Ltd. www.hi-velocity.com Return Air Temperature Sensor Module HVS Variable Speed Heat Pump Installation · For the HVS variable speed heat pump to modulate correctly, the provided return air temperature sensor must be installed in the return air ductwork, just upstream from the evaporator. · A small hole must be drilled into the return air ductwork to fit the temperature sensor in. · This sensor should be secured using tie straps/nylon cable ties or screw mount cable ties. · The hole drilled must be sealed back up after the sensor is screwed in the R/A ductwork. · This T1 temperature sensor must not exceed 23' (7m) in length. This means that the interface panel must be placed within reach of the R/A ductwork just upstream from the evaporator. Drain Fitting Installation (not provided w/ all models) 1.
