SAFETY CONSIDERATIONS Installing, starting up, and servicing air-conditioning equipment can be hazardous due to system pressures, electrical components, and equipment location (roofs, elevated structures, etc.). Only trained, qualified installers and service mechanics should install, start-up, and service this equipment. Untrained personnel can perform basic maintenance functions such as coil cleaning. All other operations should be performed by trained service personnel only.

WIRING All wires must be sized per NEC (National Electrical Code) or CEC (Canadian Electrical Code) and local codes. See the rating plate and/or the installation instructions of the compatible outdoor unit for MCA (minimum circuit amps) and MOCP (maximum over current protection) to correctly size the wires and the disconnect fuse or breakers respectively. Recommended Connection Method for Power and Communication Wiring: The main power is supplied to the outdoor unit.

INSTALLATION GUIDE INSTALLATION TIPS Before installing the outdoor unit, choose an appropriate location. Ideal installation locations include: Special Considerations for Extreme Weather If the unit is exposed to heavy wind, install the unit so the air outlet fan is at a 90° angle to the direction of the wind. If needed, build a barrier in front of the unit to protect it from extremely heavy winds.

Step 3 - Anchor the Outdoor Unit The outdoor unit can be anchored to the ground or to a wall-mounted bracket with bolt (M10). Table 7 provides a list of different outdoor unit sizes and the distance between their mounting feet. Prepare the unit’s installation base according to the dimensions in Table 7. Table 7 — Unit Mounting Dimensions SYSTEM SIZE DISTANCE A IN (MM) DISTANCE B IN (MM) 24K (HP & CO) 26.1” (663) 13.9” (354) A WARNING Use the Right Cable B D Air outlet Fig.

NOTE: If the cable clamp resembles Figure 14, select the appropriate hole according to the diameter of the wire. Buckle Three size hole: Small, Large, Medium Step 5 - Refrigerant Piping When connecting refrigerant piping, do not allow substances or gases other than the specified refrigerant to enter the unit. The presence of other gases or substances will lower the unit’s capacity and can cause abnormally high pressure in the refrigeration cycle. This can cause explosion and injury.

Unscrew the cover from the packed valve on the side of the outdoor unit. 2. Remove the protective caps from the valve ends. 3. Align the flared pipe end with each valve, and tighten the flare nut as tightly as possible by hand. 4. Using a spanner, grip the body of the valve. Do not grip the nut that seals the service valve. f.

Step 6 - Evacuate Coil and Tubing System Evacuation of the system will remove air or nitrogen (non-condensables) as well as moisture. A proper vacuum assures a tight, dry system before charging with refrigerant. The two methods used to evacuate a system are the deep vacuum method and the triple vacuum method. UNIT DAMAGE HAZARD Failure to follow this caution may result in equipment damage or improper operation. Never use the system compressor as a vacuum pump.

WIRING Step 7 - Electrical And Gas Leak Checks Size all wires per the NEC (National Electrical Code) or CEC (Canadian Electrical Code) and local codes. Use the electrical data from the outdoor unit (MCA - minimum circuit amps and MOCP - maximum over current protection), to correctly size the wires and the disconnect fuse or breakers respectively. SIZES 9-24 RECOMMENDED CONNECTION METHOD FOR POWER AND COMMUNICATION WIRING Power and Communication Wiring: The main power is supplied to the outdoor unit.
PAGE 13
MAKE REFRIGERANT PIPING CONNECTIONS (OUTDOOR UNIT) IMPORTANT: Use refrigeration grade tubing ONLY. No other type of tubing may be used. Use of other tubing types will void the manufacturer’s warranty. Copper tube Piping Guide: • Do not open service valves or remove protective caps from tubing ends until all the connections are made. • Bend the tubing with bending tools to avoid kinks and flat spots.

DRAIN CONNECTIONS CAUTION Installed drains must meet local sanitation codes. Install the outdoor unit drain joint 1. 2. 3. 4. Fit the seal into the drain joint. Insert the drain joint into the base pan hole of the outdoor unit. Rotate 90 to securely assemble them. Connect the drain joint with an extension drain hose to avoid condensate from draining off the outdoor unit during the heating mode. In cold climates, ensure the drain hose is as vertical as possible to ensure swift water drainage.

All connections between indoor and outdoor units must be as shown. The connections are sensitive to polarity and will result in a fault code. Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

SYSTEM VACUUM AND CHARGE Deep Vacuum Method UNIT DAMAGE HAZARD Failure to follow this caution may result in equipment damage or improper operation. Never use the system compressor as a vacuum pump. Refrigerant pipes and indoor unit coils should be evacuated using the recommended 500 microns deep vacuum method. The alternate triple evacuation method may be used if the following procedure is followed. NOTE: Always break a vacuum with dry nitrogen. Using a Vacuum Pump 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.

START-UP OUTDOOR UNIT DIAGNOSTIC GUIDES For ease of service, the systems are equipped with a diagnostic code display LED on both the indoor and outdoor units. The outdoor diagnostic is displayed on the outdoor unit microprocessor board. There may be a few error codes displayed on the indoor unit that might relate to the outdoor unit’s problems. If possible, always check the diagnostic codes displayed on the indoor unit first. In standby, the LED displays “- -”.
