Use 230V/60Hz or 115V/60Hz power supply only . Do not turn off the power supply circuit breaker or pull out the unit power cord during unit operation. This may cause electrical hazards and/ or a fire. Keep the power supply circuit breaker and power plug free from any type of debris. If using a power supply cord, be sure to connect to plug firmly. This will minimize the risk for electrical shock or any other type of electrical hazard.

Installation instructions Select the installation locations Indoor unit installation location: Locate indoor unit so that there is not obstruction near the supply air or return air outlets. l The wall that the indoor unit hangs on must be free from internal obstructions to facilitate a clear hole for the refrigeration lines and condensate line to go through. l Proper clearances must be maintained to ceilings and walls per instructions on page 16.
Installation instructions 3. Indoor unit refrigeration line installation l l The refrigeration lines and wiring can be routed to the outdoor unit in a number of ways (left or right from the back of the unit), by using the cut-out access pieces on the casing of the unit. Bend the refrigeration lines carefully to the required positon in order to be aligned with the drilled hole.

Mounting the Indoor unit to the Mounting Plate: Hook Hook l Hook the indoor unit onto the upper portion of the mounting plate by connecting the hooks at the rear top of the indoor unit with the upper edge of the mounting plate. l To ensure that the hooks are properly seated on the mounting plate, check if the unit can slide by moving it to the left and right. If the unit moves, it is not properly seated.
Installation instructions Outdoor unit installation 1. Install the outdoor unit l l l l Outdoor unit must be mounted on a solid, level foundation. If possible, affix unit using bolts to the foundation. If installing on a wall or structure, be sure that construction of the wall or structure can support the weight of the unit and that consideration is given to the integrity of the construction.
Installation instructions 3. Wiring connection l Remove the electrical cover of outdoor unit (1 screw). l Connect wires as shown below in the illustrations. Outdoor unit terminal block Heat Pump Connect to Power Supply Power supply inter connecting conductors (in conduit A) ( to the indoor unit) Control inter connecting conductors(in conduit B) ( to the indoor unit) The conduit should not be loosened after being fixed, otherwise, it may cause abnormal noise when the unit is running.
Installation instructions System Start Up and Charge Adjustment Procedures Leakage check Properly check refrigeration tubes and connections for any leaks prior to system start up procedures. NOTE: A is the low-pressure valve B is the high-pressure valve C and D are the joints of connecting pipes of indoor unit. Air exhaust The outdoor unit is supplied with a R-22 charge sufficient for 15 feet of refrigeration tubing.
HOW TO INSTALL DRAIN ACCESSORIES There will be some water dripping from the condenser when the heat pump is working during the heating mode. Two drain caps, a drain elbow with rubber collar and a plastic hose (5/8” x 6”) are supplied for user’s choice. INSTALLATION STEPS: (1) Observe the drainage flow of the three drain holes on the base while pouring water into the condensing unit evenly around the condenser. (Figure 1) (2) Connect the drain elbow and the plastic hose.
