INDOOR UNIT INSTALLATION STEP 1: SELECT INSTALLATION LOCATION Before installing the indoor unit, you must choose an appropriate location. The following standards must be met for an appropriate location for the unit: • • • • • • Good air circulation Convenient drainage Noise from the unit will not disturb other people Firm and solid - the location will not vibrate Strong enough to support the weight of the unit A location at least three feet (one meter) from all other electrical devices (e.g.
STEP 2: ATTACH MOUNTING PLATE TO WALL 1. Remove the screw that attaches the mounting plate to the back of the indoor unit. The mounting plate is the bracket on which you will mount the indoor unit. Screw 2. Secure the mounting plate to the wall with the anchors and screws provided. Make sure that mounting plate is flat against the wall, and is level. Correct orientation of mounting plate STEP 3: DRILL WALL HOLE FOR CONNECTIVE PIPING 1.
2. Using a 2 1/2" (65mm) core drill for units with a gas side connective pipe less than 5/8" (16mm), or 3 1/2" (90mm) for units with a gas side pipe greater than or equal to 5/8" (16mm), drill a hole in the wall. Make sure that the hole is drilled at a slight downward angle, so that the outdoor end of the hole is lower than the indoor end by about 3/16 - 1/4" (5mm to 7mm). This will ensure proper water drainage. Wall Outdoor 3/16-1/4” (5-7 mm) Indoor 3.
4. Position the piping to align with the wall hole. The refrigerant piping can exit the indoor unit from four different angles: left-hand side, right-hand side, left rear, or right rear. WARNING Be extremely careful not to dent or damage the piping while bending them away from the unit. Any dents in the piping will affect the unit’s performance. STEP 5: CONNECT THE DRAIN PIPE By default, the unit's drain pipe is attached to the left-hand side of unit (when you’re facing the back of the unit).
WARNING PLUG THE UNUSED DRAIN HOLE. To prevent unwanted leaks you must plug the unused drain hole with the rubber plug provided. STEP 6: CONNECT SIGNAL CABLE BEFORE PERFORMING ANY ELECTRICAL WORK, READ THESE REGULATIONS 1. All wiring must comply with local and national electrical codes and regulations, and must be installed by a licensed electrician. 2. All electrical connections must be made according to the Electrical Connection Diagram located on the panels of the indoor and outdoor units. 3.
The signal cable enables communication between the indoor and outdoor units. You must first choose the right cable size before preparing it for connection. USE THE RIGHT CABLE • Outdoor Power Cable: H07RN-F • Signal Cable: H07RN-F CABLE SIZING Use a minimum of 16 AWG for power and signal cables connected to and between the indoor and outdoor units.
STEP 7: PREPARE REFRIGERANT PIPING 1. If pre-existing refrigerant piping is already embedded in the wall, skip to Step 9. Then, begin the outdoor unit installation. Refer to the Refrigerant Piping Connections section of the outdoor unit's installation manual for detailed instructions. 2. If there is no pre-existing piping, connect the indoor unit’s refrigerant piping to the connective piping that will join the indoor and outdoor units.
4. Hook the top of the indoor unit on the upper hook of the mounting plate. 5. Check that the unit is hooked firmly on the mounting by applying slight pressure to the left- and right-hand sides of the unit. The unit should not jiggle or shift. 6. Using even pressure, push down on the bottom half of the unit. Keep pushing down until the unit snaps onto the hooks along the bottom of the mounting plate. 7.
