Installation space requirements

NOTICE

▪ Pipework shall be protected from physical damage.

▪ Installation of pipework shall be kept to a minimum.

WARNING

If appliances contain R32 refrigerant, the floor area of the
room in which the appliances are installed, operated and
stored MUST be larger than the minimum floor area
defined in table below A (m2). This applies to:

▪ Indoor units without a refrigerant leakage sensor; in

case of indoor units with refrigerant leakage sensor,
consult the installation manual

▪ Outdoor units installed or stored indoors (e.g. winter

garden, garage, machinery room)

▪ Pipework in unventilated spaces

To determine the minimum floor area

1 Determine the total refrigerant charge in the system (= factory

refrigerant charge + additional refrigerant amount
charged).

2 Determine which graph or table to use.

▪ For indoor units: Is the unit ceiling-mounted, wall-mounted or

floor-standing?

▪ For outdoor units installed or stored indoors, and field piping

in unventilated spaces, this depends on the installation
height:

If the installation height is… Then use the graph or table for…

<1.8m Floor-standing units

1.2.3 Refrigerant

If applicable. See the installation manual or installer reference guide
of your application for more information.

NOTICE

Make sure refrigerant piping installation complies with
applicable legislation. In Europe, EN378 is the applicable
standard.

NOTICE

Make sure the field piping and connections are NOT
subjected to stress.

WARNING

During tests, NEVER pressurize the product with a
pressure higher than the maximum allowable pressure (as
indicated on the nameplate of the unit).

WARNING

Take sufficient precautions in case of refrigerant leakage. If
refrigerant gas leaks, ventilate the area immediately.
Possible risks:

▪ Excessive refrigerant concentrations in a closed room

can lead to oxygen deficiency.

▪ Toxic gas may be produced if refrigerant gas comes

into contact with fire.

DANGER: RISK OF EXPLOSION

Pump down – Refrigerant leakage. If you want to pump

down the system, and there is a leak in the refrigerant
circuit:

▪ Do NOT use the unit's automatic pump down function,

with which you can collect all refrigerant from the
system into the outdoor unit. Possible consequence:
Self-combustion and explosion of the compressor
because of air going into the operating compressor.

▪ Use a separate recovery system so that the unit's

compressor does NOT have to operate.

WARNING

ALWAYS recover the refrigerant. Do NOT release them
directly into the environment. Use a vacuum pump to
evacuate the installation.

NOTICE

After all the piping has been connected, make sure there is
no gas leak. Use nitrogen to perform a gas leak detection.

NOTICE

▪ To avoid compressor breakdown, do NOT charge more

than the specified amount of refrigerant.

▪ When the refrigerant system is to be opened,

refrigerant MUST be treated according to the applicable
legislation.

WARNING

Make sure there is no oxygen in the system. Refrigerant
may only be charged after performing the leak test and the
vacuum drying.

▪ In case re-charge is required, refer to the nameplate of the unit. It

states the type of refrigerant and necessary amount.

▪ The unit is factory charged with refrigerant and depending on pipe

sizes and pipe lengths some systems require additional charging
of refrigerant.

▪ Only use tools exclusively for the refrigerant type used in the

system, this to ensure pressure resistance and prevent foreign
materials from entering into the system.

▪ Charge the liquid refrigerant as follows:

If Then

A siphon tube is present

(i.e., the cylinder is marked with
"Liquid filling siphon attached")

A siphon tube is NOT present Charge with the cylinder upside

▪ Open refrigerant cylinders slowly.

▪ Charge the refrigerant in liquid form. Adding it in gas form may

prevent normal operation.

CAUTION

When the refrigerant charging procedure is done or when
pausing, close the valve of the refrigerant tank
immediately. If the valve is NOT closed immediately,
remaining pressure might charge additional refrigerant.
Possible consequence: Incorrect refrigerant amount.

Charge with the cylinder upright.

2 About the documentation

1.2.6 Electrical

DANGER: RISK OF ELECTROCUTION

▪ Turn OFF all power supply before removing the

switch box cover, connecting electrical wiring or
touching electrical parts.

▪ Disconnect the power supply for more than 1 minute,

and measure the voltage at the terminals of main circuit
capacitors or electrical components before servicing.
The voltage MUST be less than 50 V DC before you
can touch electrical components. For the location of the
terminals, see the wiring diagram.

▪ Do NOT touch electrical components with wet hands.

▪ Do NOT leave the unit unattended when the service

cover is removed.

WARNING

If NOT factory installed, a main switch or other means for
disconnection, having a contact separation in all poles
providing full disconnection under overvoltage category III
condition, MUST be installed in the fixed wiring.

WARNING

▪ ONLY use copper wires.

▪ Make sure the field wiring complies with the applicable

legislation.

▪ All field wiring MUST be performed in accordance with

the wiring diagram supplied with the product.

▪ NEVER squeeze bundled cables and make sure they

do NOT come in contact with the piping and sharp
edges. Make sure no external pressure is applied to the
terminal connections.

▪ Make sure to install earth wiring. Do NOT earth the unit

to a utility pipe, surge absorber, or telephone earth.
Incomplete earth may cause electrical shock.

▪ Make sure to use a dedicated power circuit. NEVER

use a power supply shared by another appliance.

▪ Make sure to install the required fuses or circuit

breakers.

▪ Make sure to install an earth leakage protector. Failure

to do so may cause electric shock or fire.

▪ When installing the earth leakage protector, make sure

it is compatible with the inverter (resistant to high
frequency electric noise) to avoid unnecessary opening
of the earth leakage protector.

CAUTION

When connecting the power supply, the earth connection
must be made before the current-carrying connections are
established. When disconnecting the power supply, the
current-carrying connections must be separated before the
earth connection is. The length of the conductors between
the power supply stress relief and the terminal block itself
must be as such that the current-carrying wires are
tautened before the earth wire is in case the power supply
is pulled loose from the stress relief.

NOTICE

Precautions when laying power wiring:

▪ Do NOT connect wiring of different thicknesses to the

power terminal block (slack in the power wiring may
cause abnormal heat).

▪ When connecting wiring which is the same thickness,

do as shown in the figure above.

▪ For wiring, use the designated power wire and connect

firmly, then secure to prevent outside pressure being
exerted on the terminal board.

▪ Use an appropriate screwdriver for tightening the

terminal screws. A screwdriver with a small head will
damage the head and make proper tightening
impossible.

▪ Over-tightening the terminal screws may break them.

WARNING

▪ After finishing the electrical work, confirm that each

electrical component and terminal inside the electrical
components box is connected securely.

▪ Make sure all covers are closed before starting up the

unit.

NOTICE

Only applicable if the power supply is three‑phase, and the
compressor has an ON/OFF starting method.

If there exists the possibility of reversed phase after a
momentary black out and the power goes on and off while
the product is operating, attach a reversed phase
protection circuit locally. Running the product in reversed
phase can break the compressor and other parts.

5 Preparation

5.1 Overview: Preparation

This chapter describes what you have to do and know before going
on-site.

It contains information about:

▪ Preparing the installation site

▪ Preparing the refrigerant piping

▪ Preparing the electrical wiring

5.2 Preparing the installation site

Do NOT install the unit in places often used as work place. In case
of construction works (e.g. grinding works) where a lot of dust is
created, the unit MUST be covered.

Choose an installation location with sufficient space for carrying the
unit in and out of the site.

WARNING

The appliance shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).

5.2.1 Installation site requirements of the indoor unit

INFORMATION

Also read the precautions and requirements in the
"General safety precautions" chapter.

INFORMATION

The sound pressure level is less than 70dBA.

▪ Air flow. Make sure nothing blocks the air flow.

▪ Drainage. Make sure condensation water can be evacuated

properly.

▪ Wall insulation. When conditions in the wall exceed 30°C and a

relative humidity of 80%, or when fresh air is inducted into the
wall, then additional insulation is required (minimum 10 mm
thickness, polyethylene foam).

▪ Wall strength. Check whether the wall or the floor is strong

enough to support the weight of the unit. If there is a risk, reinforce
the wall or the floor before installing the unit.

Install power cables at least 1 metre away from televisions or radios
to prevent interference. Depending on the radio waves, a distance of
3metres may NOT be sufficient.

▪ Choose a location where the hot/cold air discharged from the unit

or the operation noise, will NOT disturb anyone.

▪ Fluorescent lights. When installing a wireless user interface in a

room with fluorescent lights, mind the following to avoid
interference:

▪ Install the wireless user interface as close as possible to the

indoor unit.

▪ Install the indoor unit as far as possible from the fluorescent

lights.

It is NOT recommended to install the unit in the following places
because it may shorten the life of the unit:

▪ Where the voltage fluctuates a lot

▪ In vehicles or vessels

▪ Where acidic or alkaline vapour is present

▪ In places where a mineral oil mist, spray or vapour may be

present in the atmosphere. Plastic parts may deteriorate and fall
off or cause water leakage.

▪ In places where the unit would be in the path of direct sunlight.

▪ In bathrooms.

▪ Sound sensitive areas (e.g. near a bedroom), so that the

operation noise will cause no trouble.
