Suspended.Unit.Installation
To install units that will be permanently suspended, the
units must be set on structural steel beams that are sup-
ported by vertical rods. Venmar CES recommends beams
under the full perimeter and all cross members requiring
support. In addition to these recommendations, a Struc-
tural Engineer must be involved to properly size the sup-
porting structural elements. Note that the locations of the
beams shall be coordinated with the location of access
doors to prevent any interference (see Figure 10). Single
section unit shown; for multi-sectional unit suspension,
consult factory.
Field.Fabricated.Ductwork
On indoor or indoor vertical duct connections, make con-
nections to the casing by applying Adseal 1800 silicone
based sealant or equivalent around the connection and
screwing flanged ducts directly to the casing and/or flange
with self-drilling sheet metal screws. It is important to seal
all duct connections to prevent air leakage and system
performance problems. Ductwork must be supported by
the building structure.
For duct connection sizes, see the mechanical drawings.
Insulate and weatherproof all external ductwork, joints
and roof openings with counter-flashing and mastic in
accordance with applicable codes. Ductwork running
through roof decks must comply with local fire codes.
Ducts passing through unconditioned spaces must be in-
sulated and covered with a vapor barrier.
The ventilation system should be designed according to
maximum airflow needs. To minimize noise level and loss
of pressure, ducts should be designed for a maximum air
velocity of 1,200 feet per minute, keeping the direction
and transition changes to a minimum. To further reduce
noise transmission, line the first 15 feet [4,572 mm] of
duct with acoustic insulation. Elbows with a turning radius
equal to or greater than 1, or 90º elbows with turning
vvanes, should also be used.
Electrical.Connections
The unit is factory wired (unless otherwise specified)
except for power connections, shipping split locations,
shipped loose sensors/items or remote control options
as indicated in the electrical schematics and sequence of
control. The unit may or may not have an optional factory
installed door interlocking disconnect in the control panel.
If the unit control panel disconnect is not supplied the
Electrical Contractor must provide and install disconnect
outside of the unit as per local electrical codes and run the
power supply wiring to the control panel.
• For multi-section (modular) units, the Electrical Con-
tractor must join the low voltage wiring between unit
sections using quick connections supplied by Venmar
CES and join the high voltage wiring between sec-
tions at the junction boxes or extend coiled wiring.
• Check nameplate for correct power supply require-
ments.
• See electrical schematics and sequence of control lo
cated in the control panel pocket for field wiring of
power connections, shipped loose sensors, items or
remote control interlocks. The Electrical Contractor
must locate, install and wire sensors, items or remote

WARNING
When installed, the unit must be electrically grounded in
accordance with local codes or, in the absence of local
codes, with the National Electrical Code, ANSI/NFPA70,
and/or the Canadian Electrical Code CSA C22.1. Unit
cabinet must have an uninterrupted, unbroken electrical
ground to minimize the possibility of personal injury if an
electrical fault should occur. Failure to follow this warning
could result in the installer being liable for personal injury
of others.
