NSPECTING

 

 

 

AND

 

 

 

HANDLING

 

 

 

THE

 

 

 

UNIT

 

At delivery, the package should be checked and any damage should
be reported immediately to the carrier claims agent.

When handling the unit, take into account the following:

 

1

 

Fragile, handle the unit with care.

Keep the unit upright in order to avoid compressor damage.

 

2

 

Choose on beforehand the path along which the unit is to be
brought in.

 

3

 

Lift the unit preferably with a crane and 2 belts of at least 8 m
long.

 

4

 

When lifting the unit with a crane, always use protectors to
prevent belt damage and pay attention to the position of the
unit’s centre of gravity.

 

 

5

 

Bring the unit as close to its final installation position in its
original package to prevent damage during transport. 

(See

figure 3)

NPACKING

 

 

 

AND

 

 

 

PLACING

 

 

 

THE

 

 

 

UNIT

 

 

Remove the four screws fixing the unit to the pallet.

 

 

Make sure the unit is installed level on a sufficiently strong base
to prevent vibration and noise.

 

 

Fasten the unit in place using four anchor bolts M12.

 

 

Make sure the base under the unit is extended more than
765 mm behind the unit.

 

 

The unit must be installed on a solid longitudinal foundation
(steelbeam frame or concrete) as indicated in 

figure 4

.

 

PRECAUTION

 

Block all gaps in the holes for passing out piping and wiring using
sealing material (field supply). (Small animals may enter the
machine.)

Example: passing piping out through the front

 

 

The equipment described in this manual may cause
electronic noise generated from radio-frequency
energy. The equipment complies to specifications that
are designed to provide reasonable protection against
such interference. However, there is no guarantee that
interference will not occur in a particular installation.

It is therefore recommended to install the equipment and
electric wires keeping proper distances away from stereo
equipment, personal computers, etc... 

(See figure 2)

.

In extreme circumstances you should keep distances of
3 m or more and use conduit tubes for power and
transmission lines.

 

 

In heavy snowfall areas, select an installation site
where snow will not affect operation of the unit.

 

 

The refrigerant R-410A itself is nontoxic,
nonflammable and is safe. If the refrigerant should
leak however, its concentration may exceed the
allowable limit depending on room size. Due to this it
could be necessary to take measures against
leakage. Refer to the chapter 

"9. Caution  for

refrigerant leaks" on page 17

.

 

 

Do not install in the following locations.

Locations where sulfurous acids and other corrosive
gases may be present in the atmosphere.
Copper piping and soldered joints may corrode,
causing refrigerant to leak.

Locations where equipment that produces electro-
magnetic waves is found.
The electromagnetic waves may cause the control
system to malfunction, preventing normal operation.

Locations where flammable gases may leak, where
thinner, gasoline, and other volatile substances are
handled, or where carbon dust and other incendiary
substances are found in the atmosphere.
Leaked gas may accumulate around the unit, causing
an explosion.

Do not use stands to support the corners. 

(See figure 5)

 

 

Prepare a water drainage channel around the
foundation to drain waste water from around the unit.

 

 

If the unit is to be installed on a roof, check the
strength of the roof and its drainage facilities first.

 

 

If the unit is to be installed on a frame, install the
waterproofing board within a distance of 150 mm
under the unit in order to prevent infiltration of water
coming from under the unit.
