7 INSTALLATION
WARNING: All the operation described in next chapters MUST BE DONE BY TRAINED PEOPLE ONLY. Before any
operation on the unit, be sure that the electric supply is disconnected.
7.1 GENERALITY
When installing or servicing the unit, it is necessary to strictly follow the rules listed in this manual, to conform to all the
specifications of the labels on the unit, and to take any possible precautions. Not observing the rules reported on this manual can
create dangerous situations.
After receiving the unit, immediately check its integrity. The unit left the factory in perfect condition; any eventual
damage has to be questioned to the carrier and recorded on the Delivery Note before signing it.
ADVANTIX SPA has to be informed, within 8 days, of the extent of the damage. The Customer should prepare a written statement
of any severe damage.
WARNING: The N ‐ i ‐ HP units are designed for outdoor installation. The place of installation must be entirely far away
from fire risk. All the necessary measures should be adopted in order to prevent the fire risk in the place of
installation. The outdoor ambient temperature shall not exceed 46°C. Above this value, the unit is no longer covered
by the directives in force in the area of pressure equipment.
WARNING: The unit should be installed so that adequate clearance is available for maintenance and repairation. The
warranty does not cover costs related to platforms or handling equipment necessary for any maintenance.
All maintenance and testing operations should be carried out only by QUALIFIED PERSONNEL.
Before any operation on the unit, make sure the power supply is disconnected.
WARNING: Inside the unit, there are some moving parts. Be especially careful when working near them, even if the
unit is off.
The temperatures of heads and exhaust piping of the compressor are usually high. Therefore be careful when
working near condensing coils.
The aluminum fins are very sharp and can cause serious injuries.
After the maintenance operations, close the panels tightly with the fastening screws.
7.2 LIFTING AND HANDLING
When the unloading and the placement
of the unit, it is highly recommended to
avoid any sudden or violent motion in
order to protect the inner components
and the frame. The units can be lifted by
mean of a forklift or, otherwise by mean
of belts, making sure to damage the
lateral panels and the cover of the unit
using a structure of spacers as shown in
the drawing. In this context, it is
necessary to hook indirectly the unit to
the basement but on two steel pipes of
adequate dimension that to pass into
the appropriate holes situated in the
same basement of the unit). It is
important to keep the unit horizontal
during these operations.
1) Handling with forklift
under the pallet
2) Handling with forklift
under the unit using the
appropriate windows of
passing forks
3) Handling by mean of
belts
7.3 LOCATION AND MINIMUM TECHNICAL CLEARANCES
All the N ‐ i ‐ HP models are designed for outdoor installations; any cover over the unit or locating near trees (even if they partially
cover the unit) has to be avoided in order to allow the air recirculation. It is advisable to realize a supporing basement, with
adeguate size similar to unit foot ‐ print. The unit vibration level is very low: it is advisable however, to fit a rigid rubber band
between basement and unit base ‐ frame. It is also possible to install anti ‐ vibration supports (springs or rubbers) to keep vibrations
at a very low level. An absolute care has to be taken to ensure adequate air volume to the condenser. The re ‐ circulation of
discharge air has to be avoided; failure to observe this point will result in poor performance or activation of safety controls. For
these reasons it is necessary to observe the following clearances:
