GENERAL

DL/DU units are single package air conditioners with optional

gas heating designed for outdoor installation on a rooftop or

slab and for non-residential use. These units can be

equipped with factory or field installed electric heaters for

heating applications.

These units are completely assembled on rigid, permanently

attached base rails. All piping, refrigerant charge, and electri-

cal wiring is factory installed and tested. The units require

electric power, gas supply (where applicable), and duct con-

nections. The electric heaters have nickel-chrome elements

and utilize single-point power connection.

SAFETY CONSIDERATIONS

Due to system pressure, moving parts, and electrical compo-

nents, installation and servicing of air conditioning equipment

can be hazardous. Only qualified, trained service personnel

should install, repair, or service this equipment. Untrained

personnel can perform basic maintenance functions of clean-

ing coils and filters and replacing filters.

Observe all precautions in the literature, labels, and tags

accompanying the equipment whenever working on air condi-

tioning equipment. Be sure to follow all other applicable

safety precautions and codes including ANSI Z223.1 or CSA-

B149.1- latest edition.

Wear safety glasses and work gloves. Use quenching cloth

and have a fire extinguisher available during brazing opera-

tions.

INSPECTION

As soon as a unit is received, it should be inspected for possi-

ble damage during transit. If damage is evident, the extent of

the damage should be noted on the carrier’s freight bill. A

separate request for inspection by the carrier’s agent should

be made in writing.

Should overheating occur, or the gas supply fail to

shut off, shut off the manual gas valve to the furnace

before shutting off the electrical supply.
