Handling and installation
n
All dimensions are inches. All
dimensions are ± 1/4".
n
All drawings are subject to
change without prior notice.
n
Right hand unit shown, left
hand unit opposite.
n
Mounting hardware not
provided. Mounting holes must
be located and drilled to suit
individual job requirements.
n
Remove return air bottom
panel before mounting frame
assembly.
n
Return air panel frame to be
supported independently from
unit.
n
Frame assembly must be
installed flat and square.
Failure to do so may result
in poor bottom panel fit and
improper airflow pattern. Shim
frame to support as required.
n
Telescoping skirt assembly
must be field adjusted to
assure close fit of filter rack to
louvered bottom panel.
n
Attach standard filter rack
assembly to bottom of
telescoping skirt after final
adjustment of skirt location.
Filter removal direction is
optional.
n
Portion of the inlet louver not
directly below unit inlet may
require covering in the field on
applications where infiltration
of ceiling plenum air into space
is undesired.
Telescoping bottom panel
The telescoping bottom panel
allows for fully recessing the unit
while permitting service access
into the ceiling plenum. The
architectural ceiling panel
is finished with durable powder coat
paint.
Note:
Portions of the inlet louver not
directly below unit inlet may require
covering in the field on applications
where infiltration of the ceiling
plenum air into space is undesired.
Telescoping skirt and collar assembly
must be field adjusted to assure a
proper fit between filter frame and
louvered inlet panel assembly. Refer
to assembly submittal drawings for
specific dimensions.
Improper mounting could result in the
unit falling from its position, causing
personal injury or even death.
After mounting the unit, it is then
ready for the various service
connections such as water, drain
and electrical. At this time it should
be verified that the proper types of
services are actually provided to the
unit. On those units requiring chilled
water and/or hot water, the proper
line size and water temperature
should be available to the unit.
On units with steam heating coils,
the proper line sizing and routing
should be verified. The maximum
steam pressure should never exceed
15 psig. The drain piping and steam
trap, supplied by others, should be
sized and routed to allow for proper
condensate flow.
The electrical service to the unit
should be compared to the unit
nameplate to verify compatibility.
The routing and sizing of all piping,
and the type and sizing of all wiring
and other electrical components
such as circuit breakers, disconnect
switches, etc. should be determined
by the individual job requirements
and should not be based on the size
and/or type of connection(s)
provided on the equipment.
Verify the electrical conductor
size is suitable for the distance
to the equipment connection
and will support the equipment
electrical load. All installations
should be made in compliance
with all governing codes and
ordinances. Compliance with all
codes is the responsibility of the
installing contractor.
Provide access clearance for
electrical enclosure per local
and national electrical code
requirements, minimum of 36".
It is recommended to leave 36"
access on pipe connection side.
It is also recommended to leave
room for filter removal, equivalent
to the physical size of the filter.
Horizontal hideaway unit filters
can be removed from either
side or the bottom while the
telescoping and exposed units
are bottom removal.
