Installation space requirements
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 A (ft
2
) defined in the table. (Refer to “Minimum
required floor area for each refrigerant amount charged”
on page 1.) 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. yard,
garage, machinery room)
• Pipework in unventilated spaces
NOTICE
•
Pipework should be protected from physical damage.
•
Installation of pipework should be kept to a minimum.
To determine the minimum floor area
1. Determine the total refrigerant charge in the system
(= factory refrigerant
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…
<5.9ft
Floor-standing units
5.9≤×<7.2ft
Wall-mounted units
≥7.2ft
Ceiling-mounted units
3. Use the graph or table to determine the minimum floor area.
See figure 1 on the inside of the front cover.

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. ISO 5149 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.
•
In case of R410A or R32 refrigerant: Toxic gas might
be produced if refrigerant gas comes into contact with
fire.
• In case of CO
2
refrigerant: Refrigerant gas is toxic in
high concentrations.
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.
Ensure that the outlet for the vacuum pump is not close
to any potential ignition sources and that ventilation is
available.
WARNING: RISK OF FIRE.
•
Flammable refrigerant used. To be repaired only by
trained service personnel. Do NOT puncture
refrigerant tubing.
• Dispose of properly in accordance with federal or local
regulations. Flammable refrigerant used.
•
Flammable refrigerant used. Consult repair manual/
owner’s guide before attempting to service this
product. All safety precautions must be followed.
•
Risk of fire due to flammable refrigerant used. Follow
handling instructions carefully in compliance with
national regulations.
