NSPECTING AND HANDLING THE UNIT
The units are packed in a wooden crate and attached on a wooden
pallet.
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 Lift the unit preferably with a crane
and 2 belts (1) of at least 8 m long.
3 When lifting the unit with a crane,
always use protectors (2) to prevent
belt damage and pay attention to the
position of the unit's centre of gravity.
4 Bring the unit as close to its final
installation position in its original
package to prevent damage during
transport.
U
NPACKING AND PLACING THE UNIT
1 Remove the wooden crate from the unit.
Remove the four screws fixing the unit to the pallet.
2
3 The unit must be installed on a solid longitudinal foundation
(steelbeam frame or concrete) as indicated in figure 4.
NOTE Maximum height of the foundation is 150 mm.
4 Lift the unit from the pallet and place it on its installation position.
5 Fasten the unit in place using four anchor bolts M12.
6 Remove the upper and lower service plate.
7 When closing the service panels take care that the tightening
torque does not exceed 4.1 Nm.
Prepare a water drainage channel around the
I
foundation to drain waste water from around the unit.
I 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
I
waterproofing board within a distance of 150 mm
under the unit in order to prevent infiltration of water
coming from under the unit.

Connecting the refrigerant piping

EFRIGERANT PIPING
All field piping must be installed by a licensed refrigeration
technician and must comply with relevant local and
national regulations.
NOTE Use R-407C only when adding refrigerant.
I
Installation tools:
I
Make sure to use installation tools (gauge
manifold charge hose, etc.) that are exclusively
used for R-407C installations to withstand the
pressure and to prevent foreign materials (e.g.
mineral oils such as SUNISO and moisture) from
mixing into the system.
Vacuum pump (use a 2-stage vacuum pump with
a non-return valve):
- Make sure the pump oil does not flow
oppositely into the system while the pump is
not working.
- Use a vacuum pump which can evacuate to
-100.7 kPa (5 Torr, -755 mmHg).
Installation of refrigerant piping is possible as front connection,
side connection and bottom connection.
