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.

5.1.3Guidelines when installing the drain piping

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

▪General guidelines

▪Connecting the drain piping to the indoor unit

FFA25~60A2VEB Split system air conditioners 4P456960-1 – 2017.03

▪ 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.

1~1.5 m	a

a Hanging bar O Allowed

XNot 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.

5 Installation

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.

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

2Tighten the metal clamp until the screw head is less than 4 mm from the metal clamp part.

3Check for water leaks (see "To check for water leaks" on page 7).

4Install the insulation piece (drain pipe).

5Wind the large sealing pad (= insulation) around the metal clamp and drain hose, and fix it with cable ties.

6Connect 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

1Temporarily 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).

5.2Connecting the refrigerant piping

DANGER: RISK OF BURNING

5.2.1About 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

5.2.2Precautions when connecting the refrigerant piping

INFORMATION

Also read the precautions and requirements in the following chapters:

▪General safety precautions

▪Preparation

DANGER: RISK OF BURNING

5.2.3Guidelines 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.

aPlastic watering can

bService drain outlet (with rubber plug). Use this outlet to drain water from the drain pan.

cDrain pump location

dDrain pipe connection

eDrain pipe

5Turn OFF the power.

6Disconnect the electrical wiring.

▪Remove the control box cover.

▪Disconnect the power supply and earth.

▪Reattach the control box cover.

When electrical wiring is finished already

1Start cooling operation (see "7.4 To perform a test run" on page 12).

2Gradually pour approximately 1 l of water through the air discharge outlet, and check for leaks (see When electrical wiring is not finished yet).

▪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.
