may also adversely affect the operation of these types of equipment by creating electrical noise.
Insulate pipes to prevent condensation.
- Condensation may collect and drip from the unit onto the ceiling or floor.
Keep the service valves closed until refrigerant charging is completed.
- Failure to do so will damage the unit.
Place a wet towel on the service valves before brazing the pipes to keep the temperature of
the valves from rising above 120ºC (248ºF).
- Failure to do so may result in equipment damage.
Keep the flame out of contact with the cables and metal sheet when brazing the pipes.
- Failure to do so may result in burnout or malfunction.
Use the following tools specifically designed for use with the specified refrigerant: Gauge
manifold, charge hose, gas leak detector, check valve, refrigerant charge base, vacuum
gauge, and refrigerant recovery equipment.
- Gas leak detectors for conventional refrigerants will not react to a refrigerant that does not
contain chlorine.
- If the specified refrigerant is mixed with water, refrigerant oil, or another refrigerant, the
refrigerant oil will deteriorate and the compressor will malfunction.
GB-6
WT08432X01

Use a vacuum pump with a check valve.
- If the vacuum pump oil flows back into the refrigerant lines, the refrigerant oil may deteriorate
and the compressor may malfunction.
Keep tools clean.
- If dust, dirt, or water accumulates on the charging hose or the flare processing tool, the
refrigerant will deteriorate and the compressor will malfunction.
Use refrigerant piping made of phosphorus deoxidized copper (copper and copper alloy
seamless pipes) that meets local requirements. Pipe joints should also meet local
requirements. Keep the inner and outer surfaces of the pipes clean and free of sulphur,
oxides, dust/dirt, shaving particles, oils, moisture, or any other contaminants.
- Contaminants on the inside of the refrigerant piping will cause the refrigerant oil to deteriorate
and cause the compressor to malfunction.
Store pipes indoors, and keep both ends of the pipes sealed until just before making a
flare connection or brazing. (Store elbows and other joints in plastic bags.)
- If dust, dirt, or water enters the refrigerant lines, the refrigerant oil will deteriorate and the
compressor will malfunction.
Braze the pipes with a nitrogen purge to avoid oxidation.
- Oxidized flux inside the refrigerant pipes will cause the refrigerant oil to deteriorate and cause
the compressor to malfunction.
Do not use existing refrigerant piping.
- The old refrigerant and refrigerant oil in the existing piping contain a large amount of chlorine,
which will cause the refrigerant oil in the new unit to deteriorate and cause the compressor to
malfunction.
Charge refrigerant in a liquid state.
- Charging refrigerant in the gaseous state will change the composition of the refrigerant and lead
to a performance drop.
Do not use a charging cylinder when charging refrigerant.
- The use of a charging cylinder may change the composition of the refrigerant and lead to a
performance drop.
If a large electric current flows due to a malfunction or faulty wiring, earth-leakage breakers
on the unit side and on the upstream side of the power supply system could both operate.
Depending on the importance of the system, separate the power supply system or take
protective coordination of breakers.

7. Installation location
Do not install the unit where combustible gas may leak.
- If combustible gas accumulates around the unit, fire or explosion may result.
・Provide sufficient space around the unit for effective operation, efficient air movement, and ease of access for
maintenance.
・Note that refrigerant gas is heavier than air and will therefore tend to collect in low spots such as basements.
・When an indoor unit that draws in outside air exits near the outdoor unit, be careful not to affect the normal
operation of the indoor unit.
・When the amount of drain water is excessive, drain water comes out of the outdoor unit along the panel during
heating operation. Provide sufficient space around the unit according to the instructions below.

7-2. Multiple unit installation
・When installing multiple units, make sure to take into consideration factors such as providing enough space for
people to pass through, ample space between blocks of units, and sufficient space for airflow. (The areas marked
with Ⓐin the figures below must be left open.)
・In the same way as with the single unit installation, add the dimension that exceeds the height limit (shown as "h1"
through "h3" in the figures) to L1, L2, and L3 as shown in the tables below.
・If there are walls in the front and rear of the block of units, up to six units (three units for units P500, P550, EP500,
and EP550) can be installed consecutively side by side, and a space of 1000 mm (39-3/8 in) or more must be left
between each block of six units.
・When the amount of drain water is excessive, drain water comes out of the outdoor unit along the panel during
heating operation.

8. Foundation work
Install the unit in accordance with the instructions to minimize the risk of damage from
earthquakes and strong winds.
- Improper installation will cause the unit to topple, resulting in serious injury.
The unit must be securely installed on a structure that can sustain its weight.
- Failure to do so will cause the unit to fall, resulting in serious injury.
・When performing the foundation work, make sure that the floor surface has sufficient strength and carefully route
pipes and wires in consideration of the water drainage that will be required when the unit is operated.
・If considering routing the pipes and wires across the bottom of the unit, make sure that the base is at least 100 mm
(3-15/16 in) high so that the through-holes will not be blocked.
・Provide a strong base of concrete or angle iron. If a stainless steel base is used, insulate the area between the
base and the outdoor unit by putting a rubber cushion or by applying an electrically insulated coating to prevent the
base from rusting.
・Install the unit on a level surface.
・With some types of installation, unit vibration and sound will be transmitted to the floors and walls. In such locations,
take measures to prevent vibration (such as using anti-vibration rubber pads).

・In abnormally harsh environments such as cold and/or windy areas, sufficient countermeasures to guard against
excessive wind and snow should be taken to ensure the unit’s correct operation. When the unit is expected to
operate in cooling mode in conditions under 10°C (50°F), in snowy areas, in environments subject to strong
winds or rain, install snow hoods of the following specifications (not supplied) as shown in the figure below.
Material: Galvanized steel plate 1.2T
Painting: Overall painting with polyester powder
Color: Munsell 5Y8/1 (same as the unit color)
Size: Refer to the Data Book.
ⒹⒹⒶⒷⒷⒷⒷⒸⒸⒸⒸⒸⒸⒶOutlet
ⒷInlet
ⒸSnow hood
ⒹRaised base
・Install the unit so that the wind will not blow directly against the inlet and outlet.
・If necessary, install the unit on a raised base of the following specifications (not supplied) to prevent damage
from snow.
Material: Angle iron (Build a structure that snow and wind can pass through.)
Height: Expected maximum snowfall plus 200 mm (7-7/8 in)
Width: Within the unit width (If the raised base is too wide, snow will accumulate on the raised base.)
・When the unit is used in a cold region and the heating operation is continuously performed for a long time when
the outside air temperature is below freezing, install a heater on the raised base or take other appropriate
measures to prevent water from freezing on the raised base.
・When installing a panel heater, provide sufficient space for maintenance accordingly. For details, refer to the
Data Book or installation manual for the panel heater.
