INSTALLATION OF INDOOR UNIT Step 3 Drill Hole in Wall for Interconnecting Piping, Drain & Wiring 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.
OUTDOOR UNIT PREPARATION Step 4 Install Ground Pad or Wall Hangers 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.
INSTALLATION OF REFRIGERANT PIPING Step 5 Piping Connections to Outdoor Unit CAUTION Use refrigeration grade tubing ONLY. No other type of tubing may be used. Use of other types of tubing will void manufacturer’s warranty. Make sure there is enough piping to cover the required length between the outdoor and indoor unit. Piping Preparation • Do not open service valves or remove protective caps from tubing ends until all connections are made. • Keep tubing free of dirt, sand, moisture and contaminants.
INSTALLATION OF REFRIGERANT PIPING 4. Open front cover of indoor unit and remove field wiring terminal block cover. Route the interconnecting wires to terminal block in control box. Field Wiring Cover 5. Allow interconnecting wires to hang free. Wire connections will be handled later in these instructions. 6. Adjust the length of condensate drain hose to easily meet the drain pipe of the indoor unit. Make connection and secure with a hose clamp.
INSTALLATION OF REFRIGERANT PIPING Step 6 Piping Connections to Outdoor Unit 1. Remove service valve cover (if provided) to access the service valves and refrigerant ports. 2. Carefully bend and adjust length of refrigerant pipes to meet outdoor unit service valves connections with proper tools to avoid kinks. Service Valve Cover NOTE: Use proper techniques to cut and re-flare refrigerant pipes, if required. An R410A Flaring Tool is required for re-flaring refrigerant pipes. 3.
INSTALLATION OF POWER AND WIRING Step 7 Indoor Unit Interconnecting Wire Connections WARNING Disconnect all electrical power to unit including disconnects, fuses and circuit breakers. 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.
INSTALLATION OF POWER AND WIRING Step 8 Outdoor Unit Wire Connections WARNING Disconnect all electrical power to unit including disconnects, fuses and circuit breakers. 1. Remove the service panel on right side of the outdoor unit. Cable Cross Board 2. Insert interconnecting wires and main power wires through the wire holes on conduit mounting bracket. 3. Secure main power conduit (and interconnecting wire conduit, if required) with locking nuts to conduit mounting bracket. Wire Hole 4.
INSTALLATION OF POWER AND WIRING 5. Following the same wire colors and terminal references from the indoor unit, tightly connect interconnecting wires to the outdoor unit terminal block per wiring diagram above. NOTE: Crossing interconnecting wires will cause system malfunction and possible damage. 6. Tightly connect main power wires to outdoor unit terminal block per wiring diagram above. 7. Secure all wires inside wire clamp/strain relief.
VACUUM TESTING Step 9 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. 3. Leak-test flare fittings with soap bubbles. If no leak is detected, release nitrogen. Step 10 System Vacuum and Charge CAUTION UNIT DAMAGE HAZARD Never use the system compressor as a vacuum pump. It may result in equipment damage or improper system operation.
VACUUM TESTING 5. Evacuate using either deep vacuum or triple evacuation method. 6. After evacuation is complete, fully close the low side of manifold gage and stop operation of vacuum pump. 7. The factory charge contained in the outdoor unit is good for up to 25 ft. (8 m) of line length. NOTE: For refrigerant lines longer than 25 ft (8 m), add add’l refrigerant per foot of extra piping up to the maximum allowable length. See System Requirement section on page 4 for more info 8.
