All series of air conditioners are designed for outdoor installations and are to be placed on a slab or rooftop,
however if the air conditioner is to be installed in a plant room application, please contact your equipment
supplier prior to installation.
Access for both service and installation must be provided to the compressors, control wiring and fans as
shown below.
(3) The units are equipped with hoisting plates for
rigging and hoisting of the unit.
The hoisting plates are located on the top of the
unit. When hoisting the unit with a crane,
spreader bars must be used to prevent damage
to side panels by the supporting cables.
1. SPACE REQUIRED AROUND UNITS.
(1) Care must be taken to prevent recirculation air.
To stabilize compressor, condensing pressure,
it is recommended that wherever possible the
condenser air inlet side be faced away from
prevailing winds.
(2) For rooftop installation, the type of mounting
base depends on the roof construction.
A built-up roof may not support the weight of the
unit and so it may be necessary to support the
unit by adding structural members below it.
2. INSTALLATION OF THE UNIT.
(1) The figure shows the use of the roof curb available for
mounting these units.
(2) The curb should be sealed and fixed to the roof by
weather stripping. A suggested means of sealing the
unit and roof curb is shown below.
