INSTALLATION NOTES
Warning Installation and maintenance of the unit must to be performed only by qualified personnel who have knowledge with local
codes and regulations, and experience with this type of equipment. Must be avoided the unit installation in places that could
be
considered dangerous for all the maintenance operations.
Handling
Care should be taken to avoid rough handling or shock due to dropping the unit. Do not push or pull the unit from
anything other than the base frame. Never allow the unit to fall during unloading o
r moving as this may result in serious damage. To
lift the unit, rings are provided in the base frame of the unit. Spreader bar and cables should be arranged to prevent damage
to the
condenser coil or unit cabinet.
Location
The units are produced for outside installation on roofs, floors or below ground level on condition that the area is free from
obstacles for the passage of the condenser air. The unit should be positioned on solid foundations and perfectly level; in th
e case of
installation on roofs
or floors, it may be advisable to arrange the use of suitable weight distribution beams. When the units are installed
on the ground, a concrete base at least 250 mm wider and longer than the unit’s footprint should be laid. Furthermore, this b
ase should
withstand the unit weight mentioned in the technical data table.
Space requirements The units are air-cooled, then it is important to respect the minimum distances which guarantee the best
ventilation of the condenser coils. Limitations of space reducing the air flow could cause significant reductions in cooling capacity and an
increase in electricity consumption.
To determinate unit placement, careful consideration must be given to assure a sufficient air flow across the condenser heat
transfer
surface. Two conditions must be avoided to achieve the best performance: warm air recirculation and coil starvation.
Both these conditions cause an increase of condensing pressures that results in reductions in unit efficiency and capacity.
Moreover the unique micropr
ocessor has the ability to calculate the operating environment of the air cooled chiller and the capacity to
optimize its performance staying on-line during abnormal conditions.
Each side of the unit must be accessible after installation for periodic servi
ce. 'Fig.1 and Fig.2' shows you minimum recommended
clearance requirements.
Vertical condenser air discharge must be unobstructed because the unit would have its capacity and efficiency significantly reduced.
If the units are positioned in places surrounde
d by walls or obstacles of the same height as the units, the units should follow the
minimum recommended clearance requirements shown in 'Fig.3 and Fig.4'. In the event the obstacles are higher than the units,
the
minimum recommended clearance requirements
are shown in 'Fig.5 and Fig.6'. Units installed closer than the minimum recommended
distance to a wall or other vertical riser may experience a combination of coil starvation and warm air recirculation, thus c
ausing
reduction in unit capacity and efficien
cy reductions. The microprocessor control is proactive in response “of design condition”. In the
case of single or compounded influences restricting airflow to the unit, the microprocessor will act to keep the compressor(s
) running
(at reduced capacity) rather than allowing a shut-off on high discharge pressure.
When two or more units are positioned side by side it is recommended that the condenser coils are at a minimum distance from
one
another as shown in 'Fig.7 and Fig.8'; strong wind could be the cause of air warm recirculation.
For other installation solutions, consult our technicians.
The above recommended information are representative of general installation. A specific evaluation should be done by contrac
tor
depending on the case.
