LOCATION
1.
Units may be located in the conditioned space or in an
adjacent room. Units may not be located outdoors, and
must be protected from freezing.
2.
Units should be installed in an area offering proper
power and control wiring, condenser water piping, con-
densate trap and piping, overflow if required, heating pip-
ing if required, outdoor air duct if required, and supply
and return air.
3.
Supply air may be ducted or distributed with a plenum.
Return air may be ducted, unducted or returned through
an inlet grille. If the unit is to have an outdoor air intake,
it should be located near and outside wall.
Units should be located for ease of service, with adequate
clearance for compressor access, front and right side, fan
drive access, changing filters, and heating coil service if
required. Refer to respective unit dimension detail (Figure 2,
3, and 4) for required clearances.
FOUNDATION
1.
Units may be placed on the floor or be elevated on a suit-
able platform.
2.
No special foundation or isolation is required for most
applications.
a.
Unit incorporates adequate isolation to eliminate
fan, compressor, and condensing section vibration.
Flexible duct is also recommended.
b.
It is not necessary to bolt unit to the floor or support-
ing structure.
c.
Floor or platform must be capable of supporting the
operating weight of the unit. See Table 2 for unit
weights.
3.
For installations requiring extreme quiet operation, the
following precautions should be considered:
a.
Locate unit outside the conditioned space.
b.
Supply and return air ducts should be used, con-
nected to the unit with asbestos cloth collars, and
lined with sound absorbing material.
c.
Support the unit on a separate floor structure form
that of the conditioned space.
d.
Place a non-deteriorating sound isolation pad under
the entire unit base.
CLEARANCE
Clearance must be provided for:
1.
Air intake and discharge – with or without ductwork.
2.
Condenser water piping and connections.
3.
Electrical power connections.
4.
Heating coil piping and connections, if required.
5.
Trapped condensate drain connection.
6.
Maintenance and service access. Recommended mini-
mum clearances for units are shown on the unit dimen-
sion drawing’s Figures 2, 3, and 4. These clearances
are based on standard arrangements of units. For non-
standard arrangements, allow clearances that are in line
with the recommended minimum values shown.
RIGGING
1.
Lift with slings under the unit.
2.
Use spreader bars across the top of the unit to prevent
crushing the unit frame and panels.
3.
Avoid possible surface damage by NOT removing the
carton or the skids until the unit is at or near its final loca-
tion and soon to be installed.
UNCRATNG
Keep the units in their carton until moved close to point of
installation. Units are mounted on skids and should be
“trucked” to location in a vertical position. Under no circum-
stances should they be “walked” on the corners of the crate.
1.
Remove the shipping carton.
2.
Remove skid from under the unit.
3.
Remove front access panel from condenser section.
This is necessary for access to the electrical box, con-
denser water piping and the removal of compressor ship-
ping blocks.
FOR WINTER SHUTDOWN, RESIDUAL WATER
MUST BE BLOWN FROM THE CONDENSER IF
THE UNIT IS LOCATED IN AN AREA WHERE
THE AMBIENT TEMPERATURE MAY DROP
BELOW 32°F OR IF THE UNIT HAS AN OUT-
DOOR AIR INTAKE.
