Installation General Installation Checks The checklist below is a summary of the steps required to successfully install a commercial unit. This checklist is intended to acquaint the installing personnel with what is required in the installation process. It does not replace the detailed instructions called out in the applicable sections of this manual. 1 Remove packaging and inspect the unit.
Installation Supply-Air Ductwork Install the 1" (25.4 mm) supply-air duct flange to the vertical and horizontal equipment with the (8) 5/16" (7.94 mm) factory supplied Torx head screws.
Installation Dual Filtration (GEH 1/2 to 5 ton) The horizontal, GEH model, allows the installer flexibility in design applications such as a dual filtration option. With the dual filtration design, the unit will contain a lower static which translates into a decrease in filter maintenance. For installation of a dual filtration accessory for the GEH model, verify that an extra set of return-air filter racks and filter have been ordered from the factory.
Installation Sound Attenuation Pad For sound sensitive installations, a vibration pad (field provided) should be placed beneath the horizontal or vertical equipment. For the horizontal unit, the pad should be approximately twice the size of the unit foot print. For the vertical unit, the pad should be 1/2" (12.7 mm) thick, and equal to the overall unit foot print.
Installation Supply/Return Pipe Connections Connect the supply and return hoses to the water-inlet (from supply) and water-outlet (to return) of the unit. For vibration isolation, it is recommended that flexible steel braided hoses be installed instead of hard piping the equipment to the main loop system. Figure 7 shows connection of a Hays Measurflo balancing hose kit to the water-in and water-out of a vertical unit.
Installation Types of Hose Connections (3) A circuit setter provides a means of manually balancing the water flow to the heat pump. This manual in-line balancing method is accurate up to ±20%. In order to determine flow rate, the user must record both handle position, and differential pressure drop. Then, the user must consult a chart containing both pieces of information and make the necessary adjustments to the circuit setter.
Installation Connecting a Water Regulating Valve The water regulating valve assembly is shipped as a separate item. Connections from the valve assembly to the unit must be made by the installing contractor. IMPORTANT: These valves are not positive shut-off devices. Use a slowclosing solenoid valve in the heat pump’s leaving water line to assure positive shut-off in variable-pumping applications.
Installation Power Wiring Field Installed Power Wiring Power wiring to the equipment must conform to National and Local Electric Codes (NEC) by a professional electrician. WARNING Live Electrical Components! During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks.
Installation Low Voltage Wiring Thermostat Location Location of the thermostat or zone sensor is an important element of effective room control. Areas where the thermostat or zone sensor should not be located include: Behind doors or corners; Near hot or cold air ducts; Near radiant heat (heat emitted from appliances or the sun); Near concealed pipes or chimneys; On outside walls or other non conditioned surfaces; In air-flows from adjacent zones or other units. See Figure 9 for thermostat/sensor location.
Installation Low Voltage Wiring Controls Using 24 VAC There are two factory thermostat options for the dual circuited (6 through 25 ton) equipment. Low voltage connection diagrams for deluxe 24 volt control packages for these thermostats mounted on 6 through 25 ton equipment sizes are shown in Figure 11. For controls using DC analog input/ outputs, see appropriate installation, operation and diagnostic manuals for connection. WSHP-IOP-2 (ZN510) and WSHP-PRB002-EN (ZN524).
Installation Air Flow Adjustment Blower Motor Speed-Tap Retrofit (for 1/2 Through 5 Ton Units ONLY) Motors installed in the unit include 4-speed and 3-speed configurations. All voltages include a 4-speed configuration, with the exception of 380V, 415V, 460V which contain a 3-speed arrangement and 575V which contains a 2-speed arrangement. To modify the rpm of the motor, the following steps may be followed.
Installation Air Flow Adjustment Air Flow Adjustment (6 through 25 ton units ONLY) To increase CFM, loosen the turns open set screw on the sheave, and turn the sheave clockwise. To decrease CFM, Loosen the turns open set screw on the sheave, and turn the sheave counterclockwise. To increase belt tension, loosen the adjustment bolt and pull motor mounting plate back until the belt is tight. Tighten the adjustment bolt after the belt has reached the desired tension.
Installation Waterside Economizer WARNING Hazardous Voltage! Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury. The following steps were sequenced to aid in the installation and mating of a water side economizer to a watersource heat pump (GEH 1/2 to 5 ton).
Installation Waterside Economizer 8 Thread the bulb and wire through the low voltage hole of the watersource heat pump. 11 Thread the valve’s wire lead through the low voltage hole of the heat pump. 14 Install control side service panel. 15 Install the six hanging isolation grommets into the hanging brackets The unit isolators were located in the return-air section of the unit. See Step 2. Isolators for the economizing package are located with the economizer.
Installation Waterside Economizer 19 Field pipe the drain lines of the waterside economizer and water-source heat pump together prior to installing a condensate trap. See page 51 for proper trapping of condensation.
Installation Waterside Economizer WARNING Hazardous Voltage! Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury. The following steps were sequenced to aid in the installation and mating of a waterside economizer to a watersource heat pump (GEV and GEH 6 through 25 ton models).
Installation Waterside Economizer Start-up Sequence 1 Set the thermostat to the highest position. 2 Set the thermostat system switch to COOL with the fan control to AUTO. The compressor should NOT run. 3 Reduce the thermostat setting until the compressor, reversing valve, solenoid valve, and loop pump are energized. Adjust water flow utilizing pressure/temperature plugs and comparing to tables contained in specification sheet data.
