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 Canadian
Electrical Code Part 1, C22.1 (latest editions).
2. Local plumbing and waste water codes and other applica-
ble local codes.
Refer to Table 1 for unit application data and to Tables 5 and 6
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 accordance with industry
recognized procedures identified by the Air Conditioning Con-
tractors of America.
LOCATION
Use the following guidelines to select a suitable location 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 providing adequate support under the
compressor/condenser section.
5. Maintain level tolerance of unit to 1/8" maximum.
RIGGING OR 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. Slotted
openings in the skid are provided for this purpose. Forks must
pass completely through the base.
Refer to Table 2 for unit weights and to Figure 1 for approximate
center of gravity.
