NOTICE

Do NOT install the unit tilted. Possible consequence: If the unit is tilted against the direction of the condensate flow (the drain piping side is raised), the float switch might malfunction and cause water to drip.

5.1.3 Guidelines when installing the drain piping

Make sure condensation water can be evacuated properly. This involves:

▪ Checking for water leaks

General guidelines

▪ Pipe length. Keep drain piping as short as possible. ▪ Pipe size. Keep the pipe size equal to or greater than that of the

connecting pipe (vinyl pipe of 25 mm nominal diameter and 32mm outer diameter).

▪ Slope. Make sure the drain piping slopes down (at least 1/100) to

prevent air from being trapped in the piping. Use hanging bars as shown.

a Hanging bar

O Allowed

X Not allowed

▪ Condensation. Take measures against condensation. Insulate

the complete drain piping in the building.

▪ Rising piping. If necessary to make the slope possible, you can

install rising piping.

▪ Drain hose inclination: 0~75mm to avoid stress on the piping

and to avoid air bubbles.

▪ Rising piping: ≤300 mm from the unit, ≤630~675 mm

(depending on the decoration panel used) perpendicular to the unit.

To connect the drain piping to the indoor unit

NOTICE

Incorrect connection of the drain hose might cause leaks, and damage the installation space and surroundings.

1 Push the drain hose as far as possible over the drain pipe

connection.

2 Tighten the metal clamp until the screw head is less than 4mm

from the metal clamp part.

3 Check for water leaks (see "To check for water leaks" on

page7).

4 Install the insulation piece (drain pipe). 5 Wind the large sealing pad (= insulation) around the metal

clamp and drain hose, and fix it with cable ties.

6 Connect the drain piping to the drain hose.

To check for water leaks

The procedure differs depending on whether electrical wiring is already finished. When electrical wiring is not finished yet, you need to temporarily connect the user interface and power supply to the unit.

When electrical wiring is not finished yet

1 Temporarily connect electrical wiring.

▪ Remove the control box cover (a). ▪ Connect the single-phase power supply (50Hz, 230V) to

connections No. 1 and No. 2 on the terminal block for power supply (d) and earth (c).

▪ Reattach the control box cover (a).

5.2 Connecting the refrigerant piping

DANGER: RISK OF BURNING

5.2.1 About connecting the refrigerant piping

Before connecting the refrigerant piping

Make sure the outdoor and indoor unit are mounted.

Typical workflow

Connecting the refrigerant piping involves:

▪ Connecting the refrigerant piping to the outdoor unit

▪ Connecting the refrigerant piping to the indoor unit

▪ Insulating the refrigerant piping

▪ Keeping in mind the guidelines for:

▪ Pipe bending

▪ Flaring pipe ends

▪ Brazing

▪ Using the stop valves

5.2.2 Precautions when connecting the refrigerant piping

5.2.3 Guidelines when connecting the refrigerant piping

Take the following guidelines into account when connecting pipes:

▪ Coat the flare inner surface with ether oil or ester oil when

connecting a flare nut. Tighten 3 or 4 turns by hand, before tightening firmly.

▪ Always use 2 wrenches together when loosening a flare nut.

▪ Always use a spanner and torque wrench together to tighten the

flare nut when connecting the piping. This to prevent nut cracking and leaks.
