Other field-furnished mounting devices such as rubber-
in-shear or spring-type vibration isolators selected by
the contractor or the engineer may be substituted for the
factory grommets, and should be used where factory
grommets are not provided.
Vertical unit models FHY, FSY, or FXY are designed to be
floor mounted or otherwise supported from below, and
bolted to the wall structure through the mounting holes
provided in the chassis. These units may be wall hung only
when originally ordered from the factory for wall-mount
applications. Hi-Performance vertical closet units VEY
are designed to be floor mounted or otherwise supported
from below and may be anchored directly through the
cabinet floor or the optional 6-inch legs.
The type of mounting device is a matter of choice, however
the mounting point should always be that provided in
the chassis, plenum, or cabinet. Refer to the unit product
drawings for mounting hole locations and sizes.
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.
In the case of refrigerant cooling, the proper line size
and refrigerant type should be available to the unit. On
units with steam-heating coils, the proper line sizing
and routing should be verified, and the maximum steam
pressure applied to the unit should never exceed 10 psig.
The drain piping and steam trap 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. 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.
On certain units, shipping screws or braces must be
removed after the unit is installed. Be sure to check all tags
on the unit to determine which, if any, of these devices
need to be removed.
Cooling/Heating Medium Connections
CAUTION: Toxic residues and loose particles
resulting from manufacturing and field piping
techniques such as joint compounds, soldering flux, and
metal shavings may be present in the unit and the
piping system. Special consideration must be given to
system cleanliness when connecting to solar, domestic
or potable water systems.
Submittals and product literature detailing unit operation,
controls, and connections should be thoroughly reviewed
