Bryant R-410A 583B User Manual

Page 9

Adhere to the following criteria when selecting,

sizing, and installing the duct system:

1. Units are shipped for side shot installation.

2. Select and size ductwork, supply-air registers, and return-air

grilles according to American Society of Heating, Refrig-
eration and Air Conditioning Engineers (ASHRAE) recom-
mendations.

3. Use flexible transition between rigid ductwork and unit to

prevent transmission of vibration. The transition may be
screwed or bolted to duct flanges. Use suitable gaskets to
ensure weather tight and airtight seal.

4. All units must have field-supplied filters or accessory filter

rack installed in the return-air side of the unit. Recom-
mended sizes for filters are shown in Tables 2 and 3.

5. Size all ductwork for maximum required airflow (either

heating or cooling) for unit being installed. Avoid abrupt
duct size increases or decreases or performance may be
affected.

6. Adequately insulate and weatherproof all ductwork located

outdoors. Insulate ducts passing through unconditioned
space, and use vapor barrier in accordance with latest issue

of Sheet Metal and Air Conditioning Contractors National
Association (SMACNA) and Air Conditioning Contractors
of America (ACCA) minimum installation standards for
heating and air conditioning systems. Secure all ducts to
building structure.

7. Flash, weatherproof, and vibration-isolate all openings in

building structure in accordance with local codes and good
building practices.

INSTALL ELECTRICAL CONNECTIONS

WARNING: The unit cabinet must have an uninter-
rupted, unbroken electrical ground to minimize the pos-
sibility of serious injury if an electrical fault should occur.
This ground may consist of an electrical wire connected
to the unit ground lug in the control compartment, or
conduit approved for electrical ground when installed in
accordance with NEC (National Electrical Code) ANSI/
NFPA 70 (latest edition) (in Canada, Canadian Electrical
Code CSA (Canadian Standards Association) C22.1) and
local electrical codes. Do not use gas piping as an
electrical ground. Failure to adhere to this warning could
result in serious injury or death.
