LIMITATIONS
These units must be installed in accordance with the follow-
ing national and local safety codes.
1.
National Electrical Code ANSI/NFPS No. 70 or Canadian
Electrical Code Part 1, C22.1 (latest editions).
2.
National Fuel Gas Code Z223.1 or CAN/CGA B149.1
or.2 Installation Code.
3.
Local gas utility requirements.
4.
Local plumbing and waste water codes and other appli-
cable local codes.
Refer to Table 1 for unit application data and to Table 2 for
gas 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
Contractors 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.
