[. . . ] 2 Be sure that the mounting plate has been fixed firmly enough to withstand about 60kg. Meanwhile, the weight should be evenly shared by every screw. 3 3 If the wall is made of brick, concrete or the like, drill five (5) or more holes of 5mm diameter in the wall. Insert clip anchor (item 2 on page 3) for appropriate mounting screws. 4 The water tray’s outlet for the indoor unit is twoway drainage design. 2 The drain hose should be slanted downward slightly, without distortion, bulge or fluctuation. • Cut off the tailings 1 when routing the wiring only. • Cut off the tailings 1 and tailings 2 when routing both the wiring and piping. Indoor Unit outline Connection piping Do not block water flow with a rise. Do not put the hose end into water 3 Do not put the outlet in the water. 2 The drain hose can be connected at two different positions. Use the most convenient postion and, if necessary, exchange the position of drain cap and drain hose. • The drain hose is connected at the rear left side of the indoor unit when you receive the product. bulge distortion Flooded Refrigerant Piping Drain hose (connected at the rear left side) Drain hole Drain cap 10 • Follow the instruction as below for exchanging the position of drain cap and drain hose in case from left side to right. (a)  ull out the drain cap at the rear right of P the indoor unit. Piping on the rear right side Drain cap Drain hose from the right side (b)  ull out the drain hose at the rear left of P the indoor unit. Piping on the right side Drain hose Drain hose from the left side (c)  ut the drain cap into the drain hole at the P rear left of the indoor unit. Piping on the right side Drain cap (d) nsert the drain hose into the drain hole at I the rear right of the indoor unit. Drain hose from the right side Piping on the rear left side Drain hose 3 Pipe arrangement • Arrange the pipe in the most convenient direction and position. Piping on the rear right side Drain hose from the left side Piping on the left side Drain hose from the left side Drain hose from the left side 11 • Do not route both refrigerant piping and drain hose from the right side to the left side to prevent big gap between the indoor unit and the wall. • Turn lightly the cable to make the connection easier later. • Face the end of the copper pipe/tube in a downward direction as you remove burrs in order to avoid burrs dropping into the tubing. Pipe Reamer Face down Ф12 ~ 12. 70 Ф16 ~ 15. 88 E: Check • Compare the flare work with the adjacent diagram. • If the pipe has any defect, cut off the enlarged section and redo the work. Smooth all around Improper flaring C: Putting flare nut on • Remove flare nuts attached to indoor and outdoor unit, then put them on pipe/tube having completed burr removal. Inclined Even length all around Damaged Cracked Uneven surface thickness • Make an independent covering for each pipe with the appropriate tubular isolation. 13 Step 6: Piping Connection - Indoor Unit A: Connecting the indoor unit tubing to the connection piping: • Align the centers of the pipes and sufficiently tighten the flare nut with your hands first. B: Wrap the insulation material around the connecting portion: • Cover the indoor unit pipe and the connection pipe with the heat insulation material. Bind them together with vinyl tape so that there is no gap. Cable ties Insulation material Indoor unit tubing Flare nut Pipings • Ensure to Isolate separately the suction pipe from the liquid pipe. Spanner Torque wrench Heat insulation Spanner (fixed) Flare nut wrench Torque Indoor unit tubing Pipings Suction line pipe Liquid line pipe • Wrap the insulated pipes with vinyl tape in the rear section for pipe housing. Fasten the power cable to the pipes with vinyl tape. • Then tighten the flare nut with spanner and torque wrench by referring the following: Outer diam.

Connection power cable C: Positioning the indoor unit: • Remove the spacer. • Hook the indoor unit onto the upper portion of the mounting plate (Engage the hooks of the mounting plate into the openings at the rear top of the indoor unit). Ensure that the hooks are properly seated on the mounting plate by moving the indoor unit in all directions. B: Then, tighten the flare nut with torque wrench until the wrench clicks. Outdoor Unit Liquid pipe Upper hook Mounting plate Spacer 2-way valve Suction pipe 3-way valve • Press the lower left and right sides of the unit against the mounting plate until the hooks engage into their slots (clicking sound). Upper hook Connecting cable Make sure to follow the torque table value as below: Outer diam.

[. . . ] 6 Turn the stem of the stop valve B (2-way valve) about 45° counterclockwise for 6~7 seconds after the gas coming out, then tighten the flare nut again. Make sure the pressure display in the pressure indicator is a little higher than the atmosphere pressure. 7 Remove the charge hose from the low pressure charge port. 8 Fully open the valve stems of A (3-way valve) and B (2-way valve).
