2.Roof Mounting
(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.

(1) Care must be taken to prevent recirculation of
the condenser air. To stabilize compressor
condensing pressures 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.
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 in the base
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.
