1.0 SAFETY INFORMATION

WARNING
These instructions are intended as an aid to qualified, licensed service per-
sonnel for proper installation, adjustment and operation of this unit. Read
these instructions thoroughly before attempting installation or operation.
Failure to follow these instructions may result in improper installation, adjust-
ment, service or maintenance possibly resulting in fire, electrical shock, prop-
erty damage, personal injury or death.
WARNING
The manufacturer's warranty does not cover any damage or defect to the air
conditioner caused by the attachment or use of any components, accessories
or devices (other than those authorized by the manufacturer) into, onto or in
conjunction with the air conditioner. You should be aware that the use of
unauthorized components, accessories or devices may adversely affect the
operation of the air conditioner and may also endanger life and property. The
manufacturer disclaims any responsibility for such loss or injury resulting
from the use of such unauthorized components, accessories or devices.
WARNING
Disconnect all power to unit before starting maintenance. Failure to do so can
cause electrical shock resulting in severe personal injury or death.
WARNING
Do not use oxygen to purge lines or pressurize system for leak test. Oxygen
reacts violently with oil, which can cause an explosion resulting in severe per-
sonal injury or death.
WARNING
Turn off electric power at the fuse box or service panel before making any
electrical connections.
Also, the ground connection must be completed before making line voltage
connections. Failure to do so can result in electrical shock, severe personal
injury or death.
WARNING
The unit must be permanently grounded. Failure to do so can cause electrical
shock resulting in severe personal injury or death.
WARNING
Secure elevated unit and elevating stand in order to prevent tipping. Failure to
do this may result in severe personal injury or death.
CAUTION
When coil is installed over a finished ceiling and/or living area, it is
recommended that a secondary sheet metal condensate pan be
constructed and installed under entire unit. Failure to do so may result
in property damage.
CAUTION
Single-pole contactors are used on all standard single-phase units up through
5 tons. Caution must be exercised when servicing as only one leg of the power
supply is broken with the contactor. Two pole contactors are used on some
three phase units.
CAUTION
Dual fuel (fossil fuel) applications require the use of a high pressure control in
the heat pump section. If a high pressure control was not originally provided
with the heat pump section from the factory, a factory approved high pressure
control kit must be purchased from the manufacturer and installed in the heat
pump. Dual fuel (fossil fuel) applications in which a high pressure control is
not installed in the outdoor heat pump section will void the safety approval of
the product.
