OUTDOOR UNIT INSTALLATION Ground Pad or Wall Hangers Installation 1. 2. 3. 4. Determine proper location for outdoor unit. Follow all instructions provided by manufacturer for installing wall hangers or ground pad. Verify the wall hangers or ground pad can safely support the weight of the outdoor unit. Verify the wall hangers or ground pad is level and meets all outdoor dimensional clearances.
PIPING INSTALLATION Refrigerant Piping Drill Hole in Wall If indoor unit refrigerant piping is going to exit from the rear: 1. It is recommended that the refrigerant pipe flare connectors extend through the wall to the outside. In some situations field-fabricated piping extensions will be required to extend the indoor unit refrigerant flare connections to the outside of the wall. 2. Use mounting bracket diagrams and dimensions to find and mark the proper location for the wall hole.
PIPING INSTALLATION Refrigerant Piping CAUTION Use refrigeration grade piping ONLY. Uses of other piping will void the Manufacturer’s Warranty. Piping Preparation: 1. Do not open service valves or remove protective caps on pipes until all connections are made. 2. Keep tubing free of dirt, sand, moisture and contaminants. 3. Insulate each refrigerant pipe and condensate hose with minimum 3/8” (10 mm) wall thermal pipe insulation. 4.
PIPING INSTALLATION Refrigerant Piping Piping Connections to Indoor Unit (con’t): 4. Properly align piping and tighten flare nut using a standard wrench and a torque wrench as shown in figure to the below. Carefully tighten flare nuts to correct torque level referring to the Torque Table on page 15. NOTE: Over tightening may damage flare connections and cause leaks. 5. Individually insulate each refrigerant line to prevent sweating. Insulate pipes Piping Connections to Outdoor Unit: 1.
PIPING INSTALLATION How to Relocate Drain Hose from Left to Right Side (if required) 1. Locate drain plug on right side of the drain tray. Firmly grab it and remove from drain tray. Left Right 2. Locate drain tube on the left side of drain tray. Twist drain tube counter-clockwise and gently pull to remove from the drain tray. Rubber Plug Drain 3. Position drain tube on the right side over the drain fitting. Push drain tube onto fitting and rotate clockwise to lock.

POWER AND WIRING INSTALLATION Indoor Unit Wire Connections WARNING Disconnect all electrical power to indoor and outdoor units including disconnects, fuses and circuit breakers. Lockout and tag all disconnect switches. 1. Open front cover of indoor unit and remove field wiring terminal block cover. 2. Pull interconnecting wires up from back of indoor unit and position in close to the terminal block on indoor unit.
POWER AND WIRING INSTALLATION Outdoor Unit Wire Connections WARNING Disconnect all electrical power to unit including disconnects, fuses and circuit breakers. Lockout and tag all disconnect switches. 1. Remove the service panel on right side of the outdoor unit. 2. Insert interconnecting wires and main power wires through the wire holes on conduit mounting bracket. Cable Cross Board 3. Secure main power conduit (and interconnecting wire conduit, if required) with locking nuts to conduit mounting bracket.
TESTING AND INSPECTION Leaking Test 1. Connect regulated nitrogen to manifold. Attach hose to service port. 2. Open manifold valve to add nitrogen to a pressure of 500 lbs. 3. Maintain applied pressure for 30 minutes, leak-test flare fittings with soap bubbles. If no leak is detected, release nitrogen. CAUTION Use vacuum pump, rather than refrigerant, to discharge air when installing the unit. Vacuum Procedure Important: Use a quality Micron Gauge to measure and validate the system vacuum achieved.
TESTING AND INSPECTION Vacuum Procedure (con’t) 7. Confirm that manifold valves are closed and disconnect the vacuum pump. 8. Open the service valves to the fully ‘back-seat’ position to let the refrigerant flow to the indoor unit and balance the pressure in system. Important: Do not allow air to enter the connection pipe when removing the hose. 9. Replace service valve caps and tighten.
TESTING AND INSPECTION Outdoor Oil Return Bend Oil return bend 20 ft. When the outdoor unit is more than 30 feet above the indoor unit, an oil return bend must be added for every 20 feet of connection pipe. Indoor Condensate Drain Pipe Testing Oil return bend Carefully and slowly add 8-10 ounces of water to the indoor unit drain pan. • Verify the water drains easily out the condensate drain hose.
TROUBLESHOOTING PROBLEM CAUSE/SOLUTION System does not restart. Cause: The system has a built-in three-minute delay to prevent short and/or rapid cycling of the compressor. Solution: Wait three minutes for the protection delay to expire. Indoor unit emits unpleasant odor when started Cause: Typically unpleasant odors are the result of mold or mildew forming on the coil surfaces or the air filter. Solution: Wash indoor air filter in warm water with mild cleaner.
TROUBLESHOOTING PROBLEM CAUSE/SOLUTION Water leaking from the indoor unit into the room. Cause: While it is normal for the system to generate condensate water in cooling mode, it is designed to drain this water via a condensate drain system to a safe location. Solution: If water is leaking into the room, it may indicate one of the following. • The indoor unit is not level right to left. Level indoor unit. • The condensate drain pipe is restricted or plugged.
