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 m)
•
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
Minimum length of 10 ft. apart.
Maximum line length of 50 ft. and
vertical separation of 30 ft.
•
Do not install indoor units near a direct source of heat such as
direct sunlight, steam or flame.
CAUTION
SAFETY CONSIDERATIONS
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 and on tags, stickers, and labels attached to the equipment.
Follow all safety codes. W ear safety glasses and work gloves.
Keep quenching cloth and fire extinguisher nearby when brazing.
Use care in handling, rigging, and setting bulky equipment.
WARNING
Before installing or servicing system, always turn off main power
to system and install lockout tag on disconnect. There may be
more than one disconnect switch. Electrical shock can cause
personal injury.
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.
Do not bury 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 during extended periods of system shutdown. This
causes refriger-ant slugging and could possibly damage the compressor at start-up.

MAKE REFRIGERANT PIPING CONNECTIONS (OUTDOOR
UNIT) — To connect the refrigerant lines:
Make sure to properly identify and separate between the piping and control cables coming from indoor unit No. 1 and the piping and cables coming from indoor unit No. 2
Use only "L" type sealed, dehydrated copper refrigerant tubing. No other type of tubing may be used. Use of other types of
tubing will void the manufacturer's warranty.
Do not open service valves or remove protective caps from
tubing ends until all the connections are made.
Bend tubing with special bending tools to avoid the formation of sharp bends. Take care to avoid kinks or flattening of the
tubing.
Keep the tubing free of dirt, sand, moisture, and other contaminants to avoid damaging the refrigerant system.
A void sags in the suction line to prevent the formation of oil
traps.
Insulate each tube with 3/8-in. walled thermal pipe
insulation. Inserting the tubing into the insulation before making
the connections will save time and improve installation The
suction and mixed-phase lines should never come in direct
contact.

FLARING AND CONNECTING REFRIGERANT LINES
1. Remove the protective cap from the flare fitting.
2. Remove the protective cap from the tubing and cut to the
required length. Be sure that the cut is perpendicular and
clean, without burrs.
3. Slip the flare nut on the tubing and flare the tube end using
standard flaring tools.
4. Tighten the nut until resistance is met. Mark the nut and the
fitting. Using a suitable wrench tighten an additional 1/4
turn. Use the following specified torque, according to
connection size:
Mixed-Phase line: Suction line:
1/4 in.-(12.3 ft-lb.) 1/2 in.-(36 ft-lb.)
Both refrigerant lines
need to be insulated separatly
NOTE: The service valves on the outdoor unit must remain closed
until all 4 connections have been made.
EV ACUATE TUBING AND CHARGE THE SYSTEM — When
all the fittings are connected, air must be expelled, then refrigerant charge must be checked and adjusted. Follow the steps below .
1. Open the service port cap on the suction line valve (large
valve of unit No. 1).
2. Connect the vacuum pump to the service port of unit No. 1
via the pressure gage and evacuate to 500 microns to

START-UP
System Checks
1. Conceal the tubing where possible.
2. Make sure that the drainage tube slopes downward along its
entire length.
3. Ensure all tubing and connections are properly insulated.
4. Fasten tubes to the outside wall.
5. Seal the hole through which the cables and tubing pass.
6. Connect the air conditioner to the power source and turn it
on.
7. Check all air conditioner operating modes. Refer to Owner's
Manual for operating details.
INDOOR UNIT
1. Do all the remote controller buttons function properly?
2. Do the display panel lights work properly?
3. Does the air deflection louver function properly?
4. Does the drainage work?
OUTDOOR UNIT
1. Are there unusual noises or vibrations during operation?
2. Is noise, drain water or airflow from the unit likely to disturb
the neighbors?
3. Are there any gas leaks?
EXPLAIN THE FOLLOWING ITEMS TO THE CUSTOMER,
WITH THE AID OF THE OWNER'S MANUAL:
1. How to turn the air conditioner on and off; selecting cooling,
heating and other operating modes; setting a desired temperature; setting the timer to automatically start and stop air
conditioner operation; and the other features of the remote
controller and display panel.
2. How to remove and clean the air filter.
3. How to set the air deflection louver.
4. Explain care and maintenance.
5. Present the Owner's Manual and installation instructions to
the customer.
CARE AND MAINTENANCE
The following may be performed by the equipment owner.
Outdoor Units
WARNING
Indoor Units
CAUTION
T o avoid the possibility of electric shock, before performing any
cleaning and maintenance operations, always turn off power to
the system by pressing the ON/OFF button on the remote control and turn off the separate disconnect switch located near the
unit.
If the indoor unit is on a separate switch, be sure to turn this
disconnect off as well.
CAUTION
Do not wash filter in water over 120°F (to avoid shrinkage). Do
not expose filter to fire (to avoid fire damage). Do not expose
filter to direct sunlight. Clean filter more frequently when air is
extremely dirty .
CAUTION
Do not attempt to clean or service components in controlbox.
T o Clean the Indoor Unit Front Panel — if the front panel of the
unit becomes dirty or smudged, wipe the out-side of the panel with
a soft dry cloth. Use a mild liquid deter-gent and wipe off carefully
with a dry cloth.
To Clean Indoor Coil — To clean the coil, remove indoor unit
front panel and vacuum the coil fins, using care not to bend or damage fins.
LUBRICATION — The indoor-fan, automatic air sweep, and the
outdoor-fan motors are factory lubricated and require no oiling.
Air Filters for Indoor Units
CAUTION
Operating your system with dirty air filters may damage the indoor unit and, in addition, can cause reduced perfor-mance, intermittent system operation, frost build up on the indoor coil,
and blown fuses. Inspect and clean or replace the air filters
monthly.
TO REMOVE AIR FILTERS — Open the unit's front panel by
lifting the lower part and pulling it gently outward and upward.
Pull out the filters.
TO CLEAN OR REPLACE FIL TERS — Filters can be vac-uumed
or washed in warm water. Shake filter to remove any excess water,
and replace it back. If the filter has begun to break down or is torn,
replace it. Replacement filters are available through a local dealer.
Before performing recommended maintenance, be sure unit main
power switch is turned off. Failure to do so may result in electric
shock or injury from rotating fan blade.
CLEANING COILS — Coil should be washed out with water or blown out with compressed air. Clean coil annually or as
required by location and outdoor air conditions. Inspect coil monthly
and clean as required. Fins are not continuous through coil sections. Dirt and debris may pass through first section, become trapped
between the row of fins and restrict outdoor unit airflow. Use a
flashlight to determine if dirt or debris has collected between coil
sections. Clean coil as follows:
1. Turn off unit power and install lockout tag.
2. Using a garden hose or other suitable equipment, flush coil
from the outside to remove dirt. Be sure to flush all dirt and
debris from drain holes in base of unit. Fan motors are
waterproof.
SERVICE
The following should be performed by a qualified service technician.
Clean Condensate Drains — Clean all drains and drain pans at
the start of each cooling season. Check the flow by pouring water
into the drain.
Clean or Replace Drain Pan — The drain pan should only be
cleaned or replaced by a qualified service technician.
1. Place a plastic sheet on the floor to catch any water that may
spill from the drain pan.
2. Remove the intake grille and distribution assembly.
3. Remove the condensate water in the drain pan by letting
water drain into a 3-gallon bucket.
