Duct Free Systems
Only trained, qualified installers and service mechanics should
install, start-up, and selwice this equipment.
Untrained personnel can perform basic maintenance func-
tions such as cleaning coils. All other operations should be per-
formed by trained selwice personnel.
When working on the equipment, observe precautions in the
literature and on tags, stickers, and labels attached to the equip-
ment.
Follow all safety codes. Wear safety glasses and work gloves.
Keep quenching cloth and fire extinmJisher nearby when brazing.
Use care in handling, rigging, and setting bulky equipment.
Before installing or servicing system, always turn offmain 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 servic-
ing of 38BNC/BNQ outdoor and 40BNC/BNQ indoor units cool-
ing only and heat pump duct free systems. See Table 1 for parts
included. See Tables 2 and 3 t\_rPhysical Data.
System Requirements
IMPORTANT: The Indoor unit & the inter units cable
voltage is 30 VDC.
IMPORTANT: Each refrigerant line must be insulated
Separately. See line sizing requirements in tabel 2.
Manufacturer reserves the right to discontinne, or change at an} time, specifications or designs without notice and without inc.
Pg 1
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 IV.
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 t\_r airflow
clearance on condens-ing units for wiring, refiigerant 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.
Do not bury more than 36 in. of refrigerant pipe in the _ound. 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 rec-
omlnended length is buried, refrigerant may mLm'ateto the cooler
buried section during extended periods of systeln shutdown. This
causes refiiger-ant slugging and could possibly damage the com-
pressor at start-up.

4. Remove the two screws from the air discharge opening.
Save the screws to reassemble. See Fig. 7A.
• Pull downwards and outwardston the bottom of the _itle
and gently raise the frame of the top of the unit.
• Once all covers are off; mount the unit onto the wall
mounting bracket. See Fig. 8.
NOTE: Leave covers off until after the Making Drainage Con-
nections section.
• Route the interconnecting unit's electric cable and the
outdoor sensor cable towards the lower right hand corner of
the indoor unit.
• Make sure that the wires are connected in accordance with
the wiring diagram on the inside of the unit front cover or
within this instruction manual.
• Secure the control cables to the strain relief.
• For heat pump systems only, connect the outdoor sensor
TH3 to its mating black terminal. See Fig. 9.
Make sure that all wires and screws are firmly thstened. Loose
wires or connections can cause damage and present a tire
hazard.
MAKE DRAINAGE CONNECTIONS
1. Connect the unattached end of the drainage tube to the
drainage hose outlet.
2. Seal the drainage connection to prevent leakage.
3. Make sure there are no kinks, "U" bends or flattened sections
in the tube.
4. Check that the drainage functions properly. Fill the pan below
the unit's coil with water and obsel-ve that it fieely drains out.
5. Make sure the drainage hose is at the bottom side of the walt
through-hole (see Fig. 5).
REASSEMBLE
1. Connect the display connector to the display panel printed
circuit board.
2. Put the control box cover and _ille fiame back on using the
appropriate screws (Steps 3 and 4 of Wire the Indoor Unit
section). Put the grille insert back on.

Outdoor Unit Installation
NOTE: The outdoor unit must be installed on a solid surface
0nounting base).
1. Place the rubber absorption cushions (supplied with the
outdoor unit) under the unit's feets to prevent vibrations.
2. Fasten the outdoor unit legs to the mounting base, as shown
in Fig. 12. The cushion goes between the legs and the
mounting base.
3. Be sure that the unit is leveled.
MAKE REFRIGERANT PIPING CONNECTIONS (OUTDOOR
UNIT) To connect the refrigerant lines:
Use only "L" type sealed, dehydrated copper reliigerant tub-
ing. No other type of tubing may be used. Use of other types of
tubing will void the lnanufacturer's warranty.
Do not open service valves or remove protective caps from
tubing ends until all the connections are made.
Bend robing with special bending tools to avoid the forlna-
tion of sharp bends. Take care to avoid kinks or flattening of the
tubing.
Keep the tubing tree of dirt, sand, moisture, and other con-
taminants to avoid damaging the refrigerant system.
Avoid sags in the suction line to prevent the formation ofoil
traps.
Insulate each tube with 3/8-in. walled thermal pipe insu-
lation. Inserting the tubing into the insulation before making
the connections will save time and improve installation The suc-
tion and mixed-phase lines should never come in direct contact.

2. Remove the protective cap from the robing 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 tbtlowing specified torque, according to
connection size:
Mixed-Phase line:
1/4 in.-(12.3 ft-lb.)
3/8 in.-(29 ft-lb.)
Suction line:
1/2 in.-(36 ft-lb.)
5/8 in.-(47 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.
EVACUATE TUBINGAND CHARGE THE SYSTEM When
all the fittings are connected, air must be expelled, then refriger-
ant charge must be checked and adjusted. Follow the steps below.

microns for 5 minutes.
Remove the service port caps from the mixed-phase valve
and suction line valve
Open the mixed-phase valve (small valve) with an Allen
wrench.
Open the suction line valve (large valve) with an Allen
wrench.
The outdoor unit is supplied with sufficient R-22 refriger-
ant for up to 25 ft. lineset length. Add 0.9 oz. of refriger-
ant for each additional 3 ft. of tubing length.
Make sure that the valves are properly opened. Be careful not
to open them more than required as this may damage the
thread.
Replace the service port cap. Using refrigerant oil, lubricate
the cap beam and hand tighten until resistance is met. Use a
suitable wrench to tighten the cap by an additional 1/2 turn.

START-UP
Conceal the tubing where possible.
Make sure that the drainage tube slopes downward along its
entire length.
3. Ensure all tubing and connections are properly insulated.
4. Fasten robes 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 aW 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 tempera-
ture; 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 t\_ltowing may be pert\_rmed by the equipment owner.
Outdoor Units
Before per forming recolrnnended maintenance, be sure unit main
power switch is tamed off Failure to do so may result in electric
shock or injury from rotating tan blade.
CLEANING COILS Coil should be washed out with wa-
ter 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 sec-
tions. 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.
2.
Turn offunit power and install lockout tag.
Using a garden hose or other suitable equipment, flush coil
from the outside to remove dirt. Be sure to flush all dirt and
debris fiom drain holes in base of unit. Fan motors are
waterproof.
Indoor Units
To avoid the possibility of electric shock, bet\_re performing any
cleaning and maintenance operations, always turn offpower to
the system by pressing the ON/OFF button on the remote con-
trol 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.
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
tilter to direct sunlight. Clean tilter more frequently when air is
extremely dirty.
Do not attempt to clean or seraqce components in controlbox.
To (.'lean 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 offcarefulty
with a dry cloth.
To (.'lean Indoor (,'oil To clean the coil, remove indoor unit
front panel and vacumn the coil tins, using care not to bend or dam-
age tins.
LUBRICATION The indoor-l_an, automatic air sweep, and the
outdoor-fan motors are factory lubricated and require no oiling.
Air Filters for Indoor Units
Operating your system with dirty air filters may damage the in-
door unit and, in addition, can cause reduced perfor-mance, in-
termittent 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 FILTERS Filters can be vac-uumed
or washed in warm water. Shake tilter to remove any excess water,
and replace it back. If the filter has begun to break do,am or is tom,
replace it. Replacement tilters are available through a local dealer.
SERVICE
The following should be performed by a qualified service techni-
cian.
(,'lean Condensate Drains Clean all drains and drain pans at
the start of each cooling season. Check the flow by pouring water
into the drain.
(.'lean or Replace Drain Pan The drain pan should only be
cleaned or replaced by a qualified selaqce technician.
1. Place a plastic sheet on the floor to catch any water that may
spill from the drain pan.
2.
3.
Remove the intake _itte and distribution assembly.
Remove the condensate water in the drain pan by letting
water drain into a 3-gallon bucket.
