INSTALLATION NOTES

Warning Installation and maintenance of the unit must 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 or 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 cabinet.

Location The units are produced for outdoor 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 leveled; in the 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 base 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 microprocessor 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 service. The following pictures shows you

minimum recommended clearance requirements.
