WARNING
!
Before performing service or maintenance operations on unit, turn off
main power switch to unit. Electrical shock could cause personal
injury. Improper installation, adjustment, alteration, service or mainte-
nance can cause injury or property damage. Refer to this manual.
For assistance or additional information consult a qualified installer,
service agency or the gas supplier.
CAUTION
!
This system uses R-410A Refrigerant which operates at higher pres-
sures than R-22. No other refrigerant may be used in this system.
Gage sets, hoses, refrigerant containers and recovery systems must
be designed to handle R-410A. If you are unsure, consult the equip-
ment manufacturer. Failure to use R-410A compatible servicing
equipment may result in property damage or injury.

Due to system pressure, moving parts, and electrical components,
installation and servicing of air conditioning equipment can be hazard-
ous. Only qualified, licensed service personnel should install, repair, or
service this equipment. Unlicensed personnel can perform basic main-
tenance functions of cleaning coils and filters and replacing filters.
Observe all precautions in the literature, labels, and tags accompanying
the equipment whenever working on air conditioning equipment. Install
this product in strict compliance with the installation instructions and
any applicable local, state, and national codes including, but not limited
to building, electrical, and mechanical codes.
Wear safety glasses and work gloves. Use quenching cloth and have a
fire extinguisher available during brazing operations.
INSPECTION
As soon as a unit is received, it should be inspected for possible dam-
age 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.
REPLACEMENT PARTS
Contact your local Ducted Systems parts distribution center for autho-
rized replacement parts.

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 proce-
dures such as the Air Conditioning Contractors of America (manual J).
