PIPING INSTALLATION Refrigerant Piping Drill Hole in Wall Indoor 1. Locate and mark proper location for the wall hole. 2. Cut the 2 3/4” wall hole with a 5° to 10° downward slant to the outdoors. Outdoor Wall Hole Sleeve Seal Hole 3. Insert a wall sleeve (field supplied) into hole to to prevent damage to refrigerant pipes, insulation, condensate drain hose and wiring. Hole Size Wall Hole Diagram 4.
PIPING INSTALLATION Indoor Unit Pipe Connections 1. Feed refrigerant pipes, drain hose and interconnecting wires assembly through wall hole from outdoor to the indoor unit. 2. Pull the piping assembly to the indoor unit. Carefully bend refrigerant pipes to meet indoor unit connection ports. Use proper tools to avoid kinks. Copper Oil applied (to reduce friction piping 3. Add a small amount of refrigerant oil to with the flare nut) both ends of the flare fittings. 4.
PIPING INSTALLATION Outdoor Unit Pipe Connections Carefully bend and adjust length of refrigerant pipes to meet outdoor unit port connections. See installation instructions shipped with the outdoor unit for further instructions.. Indoor Condensate Drain Piping WARNING Observe all local sanitary codes when installing condensate drains. It is recommended to install the condensate drain system with hard polyvinyl chloride (PVC) pipe and matching connectors.
PIPING INSTALLATION Multiple Units with Common Drain (Gravity Drain Configuration) The following is the recommended condensate drainage system for multiple units that share a common drain line. Connecting multiple units to one trap allows air to be pulled through one or more of the units, bypassing the trap. An alternate method is having individual drains and traps for each unit. Vertical Lift Drainage System (Internal Condensate Pump) If a gradual 2.
DUCTWORK INSTALLATION Design and Layout of Ductwork The ductwork configuration should be based on the conditions of the building and maintenance etc., as shown below.
DUCTWORK INSTALLATION Design and Layout of Ductwork The ductwork configuration should be based on the conditions of the building and maintenance etc., as shown below.
DUCTWORK INSTALLATION Duct Sizing Suggestions Correct ductwork design is critical to insure proper system performance. The total length of the ductwork is the length from the return air duct register to the supply air register. It is recommended that the ductwork and register selection should follow ACCA manual D duct design to insure proper velocity and air flow. MAX. EXT.

POWER AND WIRING INSTALLATION WARNING 1. Before obtaining access to electrical box and terminals, all electrical supply circuits must be disconnected. 2. Use a circuit breaker with adequate capacity to meet the requirements of the total system. 3. A circuit breaker or fuse should be installed per the National Electric Code (NEC) and local regulations. 4. Electrical wiring must be completed in accordance with NEC, local laws, and regulations of the electric company so that the system will operate properly.

Indoor Unit Electrical Wiring Locate and remove the electrical box cover to access wire terminals.
POWER AND WIRING INSTALLATION Electrical Connections to Concealed Duct WARNING Disconnect all electrical power to indoor and outdoor units including disconnects, fuses and circuit breakers. Lockout and tag all disconnect switches. 1. Adjust the length of the interconnecting wires so that it can easily reach the indoor unit electrical control box. 2. Open electrical control box cover and route the interconnecting wires to field wiring terminal block.
CONTROLLER INSTALLATION AND SETUP (Optional) The following is a brief overview of the Wired Tether Controller installation. See Tether Controller Owner's Manual for more detailed instructions for setup and operation. Preparation for Installation Select a proper location on the wall for mounting the Tether Controller. Install switch box, if required by code. The maximum wire length between indoor unit and Tether Controller is 26 ft (8m).
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 or Tether Controller display. Press the ON button on the Tether Controller. • Verify the Tether Controller display turns ON. 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.
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 leakage from the outdoor unit. Cause: It is normal for the outdoor unit to generate condensate water in the reverse cycle heating and defrost mode. Solution: This is normal. No action is required. 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.
DIAGNOSTIC CODES Troubleshooting The unit has onboard diagnostics. The outdoor unit will provide status indicators. The indoor wall unit and remote controller will display error codes.
