Installing, starting up, and servicing air-conditioning equipment
can be hazardous due to system pressures, electrical components,
and equipment location (roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics should
install, start-up, and service this equipment.
Untrained personnel can perform basic maintenance functions
such as cleaning coils. All other operations should be performed
by trained service personnel.
When working on the equipment, observe precautions in the
literature mid on tags, stickers, mid labels attached to the equipment.
Follow all safety codes. Wear safety glasses and work gloves.
Keep quenching cloth and fire extinguisher nearby when brazing.
Use care in handling, rigging, and setting bulky equipment.

Safety Labeling and Signal Words
DANGER, WARNING, CAUTION, and
NOTE
The signal words DANGER, WARNING, CAUTION, and
NOTE are used to identifylevels of hazard serious-
ness. The signal word DANGER is only used on
product labels to signify an immediate hazard. The
signal words WARNING, CAUTION, and NOTE will
be used on product labels and throughout this manu-
al and other manuals that may apply to the product.
DANGER - immediate hazards which will result in se-
vere personal injury or death.
WARNING - Hazards or unsafe practices which could
result in severe personal injuryor death.
CAUTION - Hazards or unsafe practices which may re-
sult in minor personal injury or product or property
damage.
NOTE - Used to highlight suggestions which will result in
enhanced installation, reliability, or operation.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Before installing or servicing system, always turn off main
power to system and install lockout tag on disconnect.
There mav be more than one disconnect switch.

The signal word WARNING is used throughout this
manual in the following manner:
The signal word CAUTION is used throughout this
manual in the following manner:
Signal Words on Product Labeling
Signal words are used in combination with colors and/or
pictures on product labels.
GENERAL
These instructions cover the installation, start-up and servicing of
DFC2A/DFC2H outdoor and DFF2A/DFF2H indoor units
cooling only and heat pump duct free systems. See Table 1 for
parts included. See Tables 2 and 3 for Physical Data.
SYSTEM REQUIREMENTS
IMPORTANT: The Indoor units & the inter units cable voltage
is 30 VDC.
IMPORTANT: Each refrigerant line must be insulated
Separately. See line sizing requirements in able 2.
• Consult local building codes and National Electrical Code
(NEC, U.S.A.) for special installation requirements.
Max. cable length. Total voltage drop should not exceed
1V. Therefore max. length:
For #18 AWG 24.3 Feet (7.4 m)
For #16 AWG 37.7 Feet (11.5 m)
For #14 AWG 50.0 Feet (18 111)
• Use only type "G" or "C" fuses. Use single length power
cable without extension. Allow sufficient space for airflow
clearance on condensing units for wiring, refrigerant piping,
and servicing unit. See Fig. 1 and 2 for minimum required
distances between unit and walls or ceilings.
• Indoor and outdoor units should be installed at a Mini-
mum length of 10 ft. apart. Maximum line length of 50 ft.
and veltical separation of 30 ft.
• Do not install indoor units near a direct source of heat such
as direct sunlight, steam or flame.
UNTF COMPONENT DAMAGE
Failure to follow this caution may result in damage to unit
components.
Do not bu_ more than 36 in. of refrigerant pipe in the ground.
If any section of pipe is buried, there must be a 6 in. vertical
rise to the valve connections on the outdoor units. If more than
the recommended length is buried, refrigerant may migrate to
the cooler buried section duNlg extended periods of system
shutdown.
