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 WARNING Refrigerant Piping CAUTION WARNING 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 at bottom of page. 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 Indoor Drain Piping The Crown indoor wall unit uses a gravity drain system. There is no internal condensate pump. The drain hose must slope downward with no kinks, raises or fluctuations. NOTE: The drain tube cannot be field re-located from the Left to the Right side of the indoor unit. 1. Connect the field supplied drain hose to the outlet pipe of indoor wall unit. A field supplied transition or adapter may be required. Outlet pipe Drain hose Drain hose 2.

POWER AND WIRING INSTALLATION IndoorWARNING Unit Wire Connections CAUTION WARNING 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 WARNING Outdoor Unit Wire Connections CAUTION WARNING 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.
TESTING AND INSPECTION Leaking Test 1. Connect the charging hose of the manifold valve to charge the end of the low-pressure valve. 2. Add dry nitrogen to a pressure of 200 lbs. Tightly close both high- and low-pressure valves. WARNING 3. Leak-test flare fittings with soap bubbles. If no leak is detected, release nitrogen. CAUTION WARNING CAUTION Use vacuum pump, rather than refrigerant, to discharge air when installing the unit.
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 Start-up Checklist □ Turn on main power to indoor and outdoor units. • Verify the system is not displaying an error code on the indoor unit display. □ Match Remote controller to indoor unit. The Crown models require the wireless remote controller to be matched to the indoor wall unit before beginning any operations, otherwise the Crown indoor wall unit will not accept commands from the remote controller.
TESTING AND INSPECTION □ Press the Mode button to Cooling. Adjust the room setpoint to bring the system on in cooling mode. The system should start cooling mode within 3-5 minutes. • Verify the outdoor fan and compressor are operating. • Verify the indoor fan is operating. • Verify the indoor discharge air is cooling the room. □ Press the Mode button to Heating. Adjust the room setpoint to bring the system on in heating mode. The system should start heating mode within 3-5 minutes.
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.
