18,000t24,000 Btuh units.
Do not install the Indoor unit units in areas
exposed to high humidity (Relative Hu=
midity of 80% or more), direct sunlight and
direct heat from stoves or other devices.
Prepare the evaporator for moundng
by removing the mounting bracket from
the rear of the indoor unit. Use a Phillips
head screwdriver to remove the unit pipe
strap. If the unit is a heat pump the de-
frost sensor also must be undone from its
retainer.
If mounting the unit on an outside wall
measure from the edges of the unit to the
center of the line set 90 ° bend to locate the
the center of the wall penetration. Drill a
3" e hole through the wall. Angle the wall
penetration slightly down towards the out-
side to assist in draining the condensate
away from the unit.
If mounting the unit on an inside walt, use
the knockouts provided on the left and
right sides d the unit to route the piping
and wiring connections through.
The indoor unit weighs a maximum of
20 Lbs. Use watt anchors to secure the
mounting bracket to a watt stud and en-
sure that the wall is capable of holding the
weight of the unit.
Be sure mounting bracket is level, so that
the condensate can drain properly.

Gauges can now be attached to the service
ports - SERVICE PORTS HAVE A 5/16"
CONNECTION TO GAUGES, which is dif-
ferent from the norm for R-22. You will need
specific hoses or an adaptor for the 5/16"
connection.
Once the gauges are attached the line
set can be leak checked using Nitrogen
at 300 psig. Evacuate the unit and inter-
connect down to a minimum of 400-500
Microns, break vacuum with Nitrogen to
further leak check.
Re-evacuate the system down to 300-400
Microns or lower for a period of one hour.
This is an R-410A System it is essential
that a deep vacuum be pulled on the sys-
tem to remove all traces of moisture. See
"System Start-Up" section to fine-tune the
refrigerant charge.

The unit is provided with approximately
18" of condensate hose connected. Hose
connection is sized to accept a 3/4" OD or
5/8" ID clear plastic hose to then extend to
building drain.
There is approximately 6' of additional
drain hose supplied with the (accessory)
line set.
All condensate hose extensions should be
in accordance with local building codes.
Remember water only flows downhill to
ensure positive draining from the unit.
Check using water for a positive flow of
condensate.
The basic system installation is now com-
plete. The unit is now ready for start up.
With the evaporator and line set completely
evacuated the system can now be opened
to allow the refrigerant charge in the out-
door unit to be released into the line set.
The condenser is charged with enough
R410A refrigerant for 16 feet of interconnect.
For longer line set lengths additional charge
must be added in per the following table.

viroAir recommends fine tuning us= I
yng the _Superheat" method, j)
Start the indoor unit, cooling mode is
only allowed when the outside ambient
temperature is above 60 ° F to prevent
damage to the compressor. Unit has a 3
minute time delay before the compressor
start up operation.
The use of the superheat method is highly
recommended for field charging or check-
ing the existing refrigerant charge in a
system that is in the cooling cycle. Because
each installation is different in terms of
indoor airflow, refrigerant line length, etc..,
the factory charge may not be correct
for every application. To assure the best
performance from the air-conditioner, the
refrigerant charge should be checked and
adjusted, if need be, on each installation.
For proper superheat readings, a standard
low=side refrigerant gauge and an accurate
thermometer is needed. A mercury or
stem=type thermometer is not adequate
for suction=line temperatures. We recom=
mend electric thermocouple thermometers
(available at most refrigeration wholesaF
ers); however an accurate remote=bulb
thermometer can be used. When measur=
ing the line temperature, be sure the theF
mometer is securely attached to assure
accurate measurements. The chart below
gives superheat values at various outdoor
temperatures. Allow at least 5 minutes run=
ning time between charge adjustments for
the unit to stabilize.

3. Measure outdoor and indoor tempera-
tures.
4. Determine from the table what the
superheat should be for the indoor and
outdoor temperatures.
5. Adjust charge if needed. Be sure unit is
running at stabilized condition.

Features of Heating Operations
Heating operation will cease at ap=
proximately 15° F outdoor tempera=
ture due to a sensor located in the
outdoor unit. This product does not
contain supplemental electric heat,
therefore other means of heat need to
used when this system ceases opera=
tion at low outdoor ambients.
Defros dnA
When the outdoor air temperature is very
low and humidity is very high, frosting will
occur in the heat exchanger of the outdoor
unit, which has negative impacts upon the
efficiency of the heating performance. In
this case, the automatic defrosting function
will come into play. The heating operation
will be stopped for 5=10 minutes to do the
defrosting.
Basic _les and #erformances
The Heat Pumps absorb heat from the
outdoor air and transfers it indoors to
heat the indoor air. The heating capa=
bilities through this principle go up/down
with the increase/decrease of the tem-
perature of the outdoor air.
When the outdoor air temperature is very
low, the system can be used together
with other heating device& Good ven=
tilation should be maintained to ensure
safety and prevent accidents.
The fans of both the outdoor and indoor
units are stopped. During the defrosting
operation, the run light wifl flash slowly.
Dudng defrosting, the outdoor unit might
generate some steam. It is caused by
fast defrosting, which is not a perfor=
mance failure.
Upon the completion of the defrosting pro=
cess, the heating operation is resumed.

mance failure.
, Upon the completion of the defrosting pro=
cess, the heating operation is resumed=
The air conditioner must be turned off before the maintenance is to be carried out.
Before the o eratinN season
1) Check if there are any materials block-
ing the intake and outlet vents of the
indoor and outdoor units,
2) Check if the installation stand is cor-
roded or rusty.
3) Check if the unit is properly grounded.
4) Check if the air filter is clean.
5) Connect to the power source=
6) Put batteries in the remote controller.
Durin¢l the ooeradn_ season
Check the air filter periodicafly during the
season and clean it if it is dirty.
ote: Do not open the grille to an angle over 60 degrees._
1)To remove the air fitter screen from the unit.
Gently press the two lower ends of
the grille and open it.
Carefully lift the air filter screen up
and out pulling it toward you.
2) To Clean the air filter screen vacuum
it with a brush attachment (do not lift
the front cover more than 60°). If the
screen is very dirty, use lukewarm wa=
ter (about 86°F or 30°C) to wash it. Air
dry after washing.
Do not use boiling water to clean the
screen.
Do not use exess heat or an open
fire to dry the screen.
Do not exert too much force pulling
or stretching the screen.
3) Replace the air filter screen.
Do not operate the air conditioner
without the air filter screen. To do
so will cause dirt to collect on the inte-
rior of the unit which may lead to poor
performance and damage the unit.
Maintenance
To clean the surface of the air conditioner:
Use a soft and dry cloth to wipe the
air conditioner off, or use a vacuum
cleaner to clean it.
, if the air conditioner is very dirty, use a
damp soft cloth with a neutral house-
hold detergent to clean the surface of
the unit.
f"NNote: If the air filter screen is blocked_
by dust or dirt, the performance of 1
cooling and heating will be affected, 1
and the operation noise and power 1
consumption will increased. There- 1
fore, the air filter screen should be 1
_,,_eaned regularly. J
A_er the o eratin season
1) Set the temperature at 86°F or 30°C and
operate in the fan status for about half a
day, to dry out the interior of the units.
2) Stop the operation of the system
and turn OFF the power switch. The
air conditioner will consume about
5W of electric power after the unit
is turned off. For energy saving and
safety, it is advisable to disconnect
the power in the off season.
3) Clean and reinstall the air filter screen.
4) Clean the surface of both the indoor
and outdoor units.
5) Take the batteries out of the remote
control.
Troub|eshooting
Check the following before requesting a_erosale service from your dealer.
ff the air conditioner does not operate at all
, Check if the main power is on.
, Is the time set to "ON" position?
(If using the timer function.)
, Check for a blown fuse or a power failure.
, Check the batteries in the remote control.
Poor eooling or heating performance
, Room temperature can't be controlled
(Too cotd or too hot). Check if the room
temperature setting too low or too high.
, Are the air filters clean (Not dogged)?
, Are the window (s) and door (s) opened?
Peer cooling performance
, Check if direct sunlight isentering the room.
, Check if there is a heat source in the
room (i.e. = hot plate, oven, stove, etc).
, Are there too many people in the room?
if the air conditioner does not operate
properly ever after conducting the above
checks, if there is still doubt even after
consulting the Baeie Operation Charae-
terisdee section on following page of this
manual, or in case of such phenomena as
described below, turn off the power and
contact your distributor.
Disconnect the power immediately, inform your installer in the following situations.
Fuse or breaker often trips off (re-
peatedly).
Remote does not initiate operation.
, Abnormal noise is heard during op-
if faulty operation is observed when
the RUN button is pressed and even
after restarting the operation after 3
minutes, faulty operation does not
disappear.
Basic Operation Characteristics_
The unit can not be restarted just after
shut down. (RUN light is on)
Air does not blow out at starting of heat=
ing operation.
Heat pump system ceases operation in
heating mode.
Air is not blown out for 6 to 12 min, at
heating operation.
Air is not blown out at DRY operation.
Mist is blown out at COOL operation.
Noise or cracking sound.
Noise is heard (cracking sound). After a
power outage or after disconnecting the
power supply plug.
Operation can not be restarted even if
the power is restored.
Remote control signals are not received.
Moisture may form on the air outlet
gdlles.
Restart is detayed for 3 minutes after shut
down to protect the unit.
Three=minute protection timer incorporated
in the microcomputer actuates automatically
Except when power is connected, this function
does not actuate.
Air circulation is stopped to prevent blowing
cold air into the room until heat exchanger
warms up. ( 2 to 5 min )
Check to see if outdoor temperature is below
15 ° F If so, operation witl not resume until the
outdoor temperature rises above 17 ° F
When outdoor temperature is low and
humidity is high, the unit sometimes per-
forms defrosting automatically,
Please wail During defrosting, water or steam
may be seen coming from the outdoor uniL
Indoor fan is sometimes stopped to prevent
vapor of dehumidified moisture and save
energy.
This phenomenon sometimes occurs when
the temperature and humidity of the room
are very high. It wil! disappear with the lower-
ing of the temperature and humidity
This is caused by the refrigerant that is circu-
lating inside the unit.
This is caused by heat expansion or contrac-
tion of plastics.
The memory circuit of the microcomputer is
cleared. Operate the remote controfler again
to restart the operation.
Remote control signats may not be re=
ceived when signal receiver on the air con-
ditioner body is exposed to direct sunlight
or strong lighting. Interrupt the sunlight or
dim the lighting.
tf the unit is operated for a long period of
time with the high humidity, moisture may
form on the air outlet grifles and drip down.
