--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.

WT07281X03	GB-6

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.

6. Transporting the unit

When lifting the unit, pass the slings through the four designated sling holes.

--Improper lifting will cause the unit to topple or fall, resulting in serious injury.

Always use two slings to lift up the unit. Each sling must be at least 8 m (26 ft) long and must be able to support the weight of the unit.

Put protective pads between slings and the unit where the slings touch the unit at the base to protect the unit from being scratched.

Put 50 mm (2 in) or thicker protective pads between slings and the unit where the slings touch the unit at the top of the unit to protect the unit from being scratched and to avoid contact with the slings and the fan guard.

Make sure that the angles between slings at the top are less than 40 degrees.

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.

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 EP400 through EP500) 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.

(1) Side-by-side installation

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).

[mm (in)]

(1) Without a detachable leg

<![if ! IE]> <![endif]>≤ 30 (1-3/16)

(2) With a detachable leg

<![if ! IE]> <![endif]>≤ 30 (1-3/16)

M10 anchor bolt (not supplied)

(Incorrect installation) The corner section is not securely received.

Fixing bracket for post-installed anchor bolts (not supplied) (To be fixed with three screws)

Anti-vibration rubber pad

(The pad needs to be large enough to cover the entire width of each unit leg.)

Detachable leg

Make sure that the corner section is securely received. If not, the unit legs could bend.The length of the projecting part of the anchor bolt should be 30 mm (1-3/16 in) or less.

This unit is not designed to be anchored with post-installed anchor bolts unless fixing brackets are installed at the bottom four locations (six locations for units EP400 through EP500).
