Installation
Before any operation please check the instruction for use.
Warning
Installation and maintenance are to be performed only by qualified personnel who are familiar with local codes and
regulations, and who are experienced with this type of equipment. Must be avoided the installation of the unit in
places that could be considered dangerous for maintenance operations.
Receiving and Handling
Inspect the unit immediately after receipt for possible damage. The unit is shipped ex-factory and all claims for
handling and shipping damage are the responsibility of the consignee. Leave the shipping skid in place until the
unit is in final position. This will aid in handling the equipment. Use extreme care when rigging the equipment to
prevent damage to the control center, or refrigerant piping.
Lift the unit by fastening the rigging hooks to the four corners of the evaporator where the rigging eyes are located
(see Figure 1). Use spreader bars between the rigging lines to prevent damage to the control center.

Location
A levelled and sufficiently strong floor is required. If necessary, additional structural members should be provided
to transfer the weight of the unit to the nearest beams.
Rubber-in-shear isolators can be furnished and field placed under each corner of the package. A rubber anti–skid
pad should be used under isolators if hold-down bolts are not used.
Vibration isolator in all water piping connected to the chiller are recommended to avoid straining the piping and
transmitting vibration and noise.
Compressor Condensation
Condensation occurs on the compressor surface when the temperature of the compressor surface is lower than
the ambient dew point temperature. Drain pans with drain connections are provided underneath each compressor
to collect the condensate. The compressor motor housing extends past the drain pans. Install a floor drain close to
the unit to collect condensate from motor housing and condensate pans.
Water treatment
If unit is operating with a cooling tower, clean and flush cooling tower. Make sure tower "blowdown" or bleedoff is
operating. Atmospheric air contains many contaminants which increases the need for water treatment. The use of
untreated water may result in corrosion, erosion, sliming, scaling, or algae formation. A water treatment service is
