7a—Installation with Conventional Electric Water Heater 7. Insulate all water pipes with closed-cell foam type insulation with a minimum wall thickness of 3/8 in. 8. If shut off valves have been installed in the water lines between the tank and compressor section, slowly open all valves. Bleed air from the heat pump water circuit and circulating pump. First loosen the threaded union on the pump outlet until water flows out and no air is present. Retighten union. Repeat process with union on pump inlet. Then loosen air bleed screw in the center of the circulating pump. The air bleed screw should only be loosened, not totally removed, enough to allow air to bleed. Retighten screw after system has been bled. A CAUTION Failure to bleed air from the water pump before energizing will cause immediate pump failure. The pump employs water-cooled and lubricated bearings; and if air is left in the vicinity of the bearing, insufficient cooling and lubrication will be available and bearing failure will result. ELECTRICAL CONNECTIONS NOTE: This equipment generates and uses radio frequency energy. If not installed properly in strict accordance with these installation instructions, it may cause interference with televisions and/or radio reception. It has been tested and found to comply with the limits for a Class B computing device in accordance with the specifications in Subpart J of Part 15 of FCC rules (which are designed to provide protection against such interference in a residential installation). However, there is no guarantee that there will not be interference in a particular installation. If this equipment does cause interference to television and/or radio reception, which can be determined by turning the equipment off and on, the installer or serviceman should refer to “38QE Startup, Troubleshooting and Service Guide.” Fig. 7b—Installation with Gas Water Heater and Preheat Tank Tank Water Temperature Thermostat Adjust the lower electric heater thermostat to the minimum setting. Water Piping Installation 1. Shut off all electrical power to domestic water heater. 2. Shut off water supply to domestic water heater and drain tank. Remove drain valve from bottom of tank which requires sensor (Fig. 7a or 7b). Install pipe nipples and tee and install tank water temperature sensor as shown in Fig. 8. Bend sensor up to avoid hitting water tanks that have dome shaped bottoms. Install second tee into tank sensor tee as shown in Fig. 8. Install drain valve and connect water piping between second pipe tee and hot water outlet connection on the compressor section. 5. Install a tee fitting on the cold city water supply as shown in Fig. 7. Install the water piping between the tee fitting and the cold water inlet connection on the compressor section. 6. Refill the hot water pipes and tank, purge air, and check all water connections for leaks. HOT WATER FROM 38QE COMPRESSOR SECTION 3. 4.

IMPORTANT: The use of aluminum wire for any power or control wiring is not allowed, all electrical wiring must be copper; and all wiring specifications pertaining to the 38QE system are specified as copper wire using American Wire Gauge (AWG) sizing system Step 11 —Install Control and Sensor Wiring The control wiring consists of connections between the compressor section, water heater control box, indoor fan coil and the thermostat. Sensor wiring is connected between the outdoor fan coil and the compressor section. Sensor wiring is also connected between the water heater tank and the domestic water heating control box. Control and sensor wiring requires standard "thermostat type and gauge of wire. The plenum cable listed in Table 2 is recommended. Compressor Section to Indoor Fan Coil Section Run one length of 3 conductor wire. See Fig. 9 for connection schematic. These...
