Rig and Mount the Unit:
REDUCED EQUIPMENT LIFE HAZARD
Failure to follow these precautions could result in
damage to the unit being installed.
Be sure unit panels are securely in place prior to rigging.
CAUTION
!
RIGGING -- See Figure 2. These units are designed for
overhead rigging. Refer to rigging label for preferred
rigging method. Spreader bars are not required if top
crating is left on unit. All panels must be in place when
rigging. As further protection for coil faces, plywood sheets
may be placed against sides of unit, behind cables. Run
cables to a central suspension point so that angle from the
horizontal is not less than 45 degrees. Raise and set unit
down carefully.
If it is necessary to roll the unit into position, mount the unit
on field--supplied rails placed lengthwise under the unit
using a minimum of 3 rollers. Apply force to the rails, not the
unit. If the unit is to be skidded into position, place it on a
large pad and drag it by the pad. Do not apply any force to
the unit.
Raise from above to lift unit from the rails or pad when unit
is in final position.
After unit in position, remove all shipping materials and top
crating.
NOTE: Before mounting unit, remove holddown brackets
and release skid. If conditions or local codes require unit to
be fastened to pad, use the mounting holes in the base
rails.
Clearances:
Locate unit so that outdoor coil (condenser) airflow is
unrestricted on all sides and above. See Figure 1 for unit
clearances, weight, and clearance data.
Unit Support:
The unit must be level, and supported above grade by
beams, platform or a pad. Platform or pad can be of open or
solid construction but should be of permanent materials
such as concrete, bricks, blocks, steel or pressure treated
timbers approved for ground contact. Refer to Unit
Clearances and weights to help determine size of supports
etc. Soil conditions should be considered so the platform or
pad does not shift or settle excessively and leave the unit
only partially supported.
REDUCED EQUIPMENT LIFE HAZARD
Failure to follow these precautions could result in
damage to the unit being installed.
Inadequate support could cause excessive vibration
and noise or binding and stress on refrigerant lines
resulting in equipment failure.
To minimize vibration or noise transmission, it is
recommended that supports not be in contact with the
building structure. However, slabs on grade construc-
tions with an extended pad are normally acceptable.
CAUTION
!
A. Ground Level Installation:
If beams or an open platform are used for support it is
recommended that the soil be treated or area be graveled
to retard the growth of grasses and weeds.
B. Roof Top Installation:
This type of installation is not recommended on wood
frame structures where low noise levels are required.
Supporting structure or platform for the unit must be level. If
installation is on a flat roof the unit should be 4 inches
(10cm.) above roof level. Four by four posts placed over a
load bearing wall make a suitable mounting platform.
If possible, place the unit over one or more load bearing
walls. If there are several units, mount them on platforms
that are self--supporting and span load bearing walls.
These suggestions are to minimize noise and vibration
transmission through the structure.
