Required filter sizes shown are based on the larger of the ARI (Air Conditioning and Refrigeration Institute) rated cooling airflow or the heating airflow velocity of 300
ft./min, for throwaway type or 450 ft./rain, for high-capacity type. Air filter pressure drop for non-standard filters must not exceed 0.08 in. wg.

12. Size all ductwork lk_r maximum required airflow (either
healing or cooling) lk_runit being installed. Avoid abrupt duct
size increases or decreases or perlormance may be afl_.:cted.
13. Adequately insulate and weatherproof all ductwork located
outdoors. Insulate ducts passing through unconditioned space,
and use vapor barrier in accordance with la_est issue of Sheet
Metal and Air Conditioning Contractors National Association
(SMACNA) and Air Conditioning Contractors of America
(ACCA) ndnimum installation standards lot heating and air
conditioning systems. Secure all ducts to building structure.
14. Flash, weatherproof, and vibration-isolate all openings in
building structure in accordance with local codes and good
building practices.
Step 8--Install Electrical Connection
The unit cabinet must have an uninterrupted, unbroken
electrical ground to minimize the possibility of personal
in,iury 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 l_r electrical
ground when installed in accordance with NEC (National
Electrical Code) ANSI/NFPA (latest edition) and local elec-
trical codes. In Canada, lollow Canadian Electrical Code
CSA (Canadian Standards Association) C22.1 and local
electrical codes. Failure to adhere to this warning could result
in personal injury or death.
