Indoor Unit Installation 1. Installing the mounting plate • The mounting plate should be installed on a wall which can support the weight of the indoor unit. 1) Temporarily secure the mounting plate to the wall, make sure that the panel is completely level, and mark the drilling points on the wall. 2) Secure the mounting plate to the wall with screws.
English 2. Drilling a wall hole and installing wall embedded pipe WARNING For metal frame or metal board walls, be sure to use a wall embedded pipe and wall hole cover in the feed-through hole to prevent possible heat, electric shock, or fire. • Be sure to caulk the gaps around the pipes with caulking material to prevent condensation.
Indoor Unit Installation 3-2. Left-side, left-back, or left-bottom piping How to replace the drain plug and drain hose • Replacing onto the left side 1) Remove the fixing screw of drain hose on the right and remove the drain hose. 2) Remove the drain plug on the left side and attach it to the right side. 3) Insert the drain hose and tighten with the included fixing screw. Forgetting to tighten this may cause water leakages. Drain hose attachment position The drain hose is on the back of the unit.
English 4. Wiring 1) As shown in the illustration, insert the wires including the ground wire into the conduit and secure them with lock nut onto the conduit mounting plate. 2) Strip wire ends (3/4 inch (20mm)). 3) Match wire colours with terminal numbers on the terminal block of indoor and outdoor unit and firmly secure the wires in the corresponding terminals with screws. 4) Connect the ground wire to the corresponding terminals. 5) Pull the wires lightly to make sure they are securely connected.
Refrigerant Piping Work 1. Flaring the pipe end 1) Cut the pipe end with a pipe cutter. 2) Remove burrs with the cut surface facing downward, so that the filings do not enter the pipe. 3) Put the flare nut on the pipe. 4) Flare the pipe. 5) Check that the flaring has been done correctly. Cut exactly at right angles. Set exactly at the position shown below. Flare tool for R410A A Clutch-type Die A 0-0.020 inch (0-0.5mm) Remove burrs.
English 2-2. Selection of copper and heat insulation materials When using commercial copper pipes and fittings, observe the following: • Insulation material: Polyethylene foam Heat transfer rate: 0.041 to 0.052W/mK (0.024 to 0.030Btu/fth°F (0.035 to 0.045kcal/mh°C)) Be sure to use insulation that is designed for use with HVAC Systems. • ACR Copper only.
2. Removing and installing the front grille • Removal method 1) Remove the front panel to remove the air filter. 2) Remove the 2 screws from the front grille. (The 15, 18 and 24-class models have 3 screws.) 3) In front of the mark on the front grille, there are 3 upper hooks.

1. English Trial Operation and Testing Trial operation and testing • Trial operation should be carried out in either COOL or HEAT operation. 1-1. Measure the supply voltage and make sure that it is within the specified range. 1-2. In COOL operation, select the lowest programmable temperature; in HEAT operation, select the highest programmable temperature. 1-3.
