Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 General Information Inspection Upon receipt of the equipment, carefully check the shipment against the bill of lading. Make sure all units have been received. Inspect the packaging of each unit, and inspect each unit for damage. Insure that the carrier makes proper notation of any shortages or damage on all copies of the freight bill and completes a common carrier inspection report.
Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 Horizontal Installation NOTICE! Failure to remove shipping brackets from springmounted compressors will cause excessive noise, and could cause component failure due to added vibration. Horizontal Unit Location Units are not designed for outdoor installation. Locate the unit in an INDOOR area that allows enough space for service personnel to perform typical maintenance or repairs without removing unit from the ceiling.

Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 Field Conversion of Air Discharge Overview Horizontal units can be field converted between side (straight) and back (end) discharge using the instructions below. Figure 4: Left Return Side to Back Remove Screws Water Connection End Return Air Note: It is not possible to field convert return air between left or right return models due to the necessity of refrigeration copper piping changes.
Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 Horizontal Installation Condensate Piping – Horizontal Units Pitch the unit toward the drain as shown in Figure 2 to improve the condensate drainage. On small units (less than 2.5 tons/8.8 kW), insure that unit pitch does not cause condensate leaks inside the cabinet. Install condensate trap at each unit with the top of the trap positioned below the unit condensate drain connection as shown in Figure 6.
Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 Vertical Installation Vertical Unit Location Units are not designed for outdoor installation. Locate the unit in an INDOOR area that allows enough space for service personnel to perform typical maintenance or repairs without removing unit from the mechanical room/closet. Vertical units are typically installed in a mechanical room or closet.
Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 Vertical Installation Sound Attenuation for Vertical Units Sound attenuation is achieved by enclosing the unit within a small mechanical room or a closet. Additional measures for sound control include the following: 1. Mount the unit so that the return air inlet is 90° to the return air grille. Refer to Figure 9. Install a sound baffle as illustrated to reduce line-of sight sound transmitted through return air grilles. 2.
Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 Water Connection Installation External Flow Controller Mounting The Flow Controller can be mounted beside the unit as shown in Figure 12. Review the Flow Controller installation manual for more details. Water Connections-Residential (Distributor) Models Residential models utilize swivel piping fittings for water connections that are rated for 450 psi (3101 kPa) operating pressure.
Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 Ground-Loop Heat Pump Applications from the system, the level will drop only 1-2 inches (2.5 - 5 cm) in a 10” (25 cm) diameter PVC flush tank (about a half gallon [2.3 liters]), since liquids are incompressible. If the level drops more than this, flushing should continue since air is still being compressed in the loop fluid. Perform the “dead head” procedure a number of times.

Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 Hot Water Generator The HWG (Hot Water Generator) or desuperheater option provides considerable operating cost savings by utilizing excess heat energy from the heat pump to help satisfy domestic hot water requirements. The HWG is active throughout the year, providing virtually free hot water when the heat pump operates in the cooling mode or hot water at the COP of the heat pump during operation in the heating mode.
Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 Hot Water Generator Installation The HWG high limit temperature switch is set at 125°F [52°C] and is located on the HWG heat exchanger “Water In” line. If the HWG is connected incorrectly or if circulation is reversed, the aquastat will sense leaving water temperature and prevent HWG operation.

Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 CXM Controls Safety Features – CXM Control The safety features below are provided to protect the compressor, heat exchangers, wiring and other components from damage caused by operation outside of design conditions. Anti-short cycle protection: The control features a 5 minute anti-short cycle protection for the compressor. Note: The 5 minute anti-short cycle also occurs at power up.
Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 CXM Controls CXM Control Start-up Operation The control will not operate until all inputs and safety controls are checked for normal conditions. The compressor will have a 5 minute anti-short cycle delay at power-up. The first time after power-up that there is a call for compressor, the compressor will follow a 5 to 80 second random start delay. After the random start delay and anti-short cycle delay, the compressor relay will be energized.

Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 Unit Starting And Operating Conditions Determination of operating limits is dependent primarily upon three factors: 1) return air temperature. 2) water temperature, and 3) ambient temperature. When any one of these factors is at minimum or maximum levels, the other two factors should be at normal levels to insure proper unit operation. Consult product catalog for operating temperature limits.
Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 Unit Starting and Operating Conditions Unit and System Checkout BEFORE POWERING SYSTEM, please check the following: UNIT CHECKOUT Balancing/shutoff valves: Insure that all isolation valves are open and water control valves are wired. Line voltage and wiring: Verify that voltage is within an acceptable range for the unit and wiring and fuses/ breakers are properly sized. Verify that low voltage wiring is complete.
Residential H&V - 60Hz R22 &R410A R e v. : 2 2 D e c , 2 0 0 8 Unit Start-Up Procedure c. Verify that the compressor is on and that the water flow rate is correct by measuring pressure drop through the heat exchanger using the P/T plugs and comparing to Tables 9a through 9c. d. Check the elevation and cleanliness of the condensate lines. Dripping may be a sign of a blocked line. Check that the condensate trap is filled to provide a water seal. e. Refer to Table 10.
