INSTALLATION
LIMITATIONS
These units must be installed in accordance with the
following national and local safety codes.
1. National Electrical Code ANSI/NFPS No. 70 or Cana-
dian Electrical Code Part 1, C22.1 (latest editions).
2. Local plumbing and waste water codes and other
applicable local codes.
Refer to Table 1 for unit application data and to Table 4
for electric heat application data.
If components are to be added to a unit to meet local
codes, they are to be installed at the dealer's and/or
the customer's expense.
Size of unit for proposed installation should be based
on heat loss/heat gain calculations made in accor-
dance with industry recognized procedures identified
by the Air Conditioning Contractors of America.
LOCATION
Use the following guidelines to select a suitable loca-
tion for these units.
1. Unit is designed for outdoor installation only.
2. Condenser must have an unlimited supply of air.
Where a choice of location is possible, position unit
on either north or east side of building.
3. For ground level installation, a level pad or slab
should be used. The thickness and size of the pad
or slab used should meet local codes and unit
weight. Do not tie the slab to the building foundation.
4. For roof top installation, be sure the structure will
support the weight of the unit plus any field
installed components. Unit must be installed on a
level roof curb or appropriate angle iron frame pro-
viding adequate support under the compressor/
condenser section.
5. Maintain level tolerance of unit to 1/8" maximum.
RIGGING AND HANDLING
Care must be exercised when moving the unit. Do not
remove any packaging until the unit is near the place of
installation. Rig unit with slings placed under the unit.
Spreader bars of sufficient length should be used
across the top of the unit.
BEFORE LIFTING A UNIT, MAKE SURE THAT ITS
WEIGHT IS DISTRIBUTED EQUALLY ON THE
CABLES SO THAT IT WILL LIFT EVENLY.
Units may also be moved or lifted with a fork-lift. Slot-
ted openings in the skid are provided for this purpose.
Forks must pass completely through the base.
