Cracking sound is heard.  
It smells.  
This is caused by heat expansion or contraction of plastics.  
Air which blows out from the indoor unit sometimes smells.  
The smell results from residents of tobacco smoke or cosmetics  
stuck inside of unit.  
When the air conditioner is used at restaurant etc. where dense  
edible oil fume is always exists, white fog sometimes blows out  
of air outlet during operation.  
During operation,  
white fog comes  
out of indoor unit.  
In this case consult sales dealer for cleaning the heat exchanger.

For Preparation of Heating("Hot Keep")  
"HOT KEEP"is operated in the following cases.  
When heating is started:  
In order to prevent blowing out of cool wind, the indoor unit fan stopped  
according to the room temperature which heating operation is started. Wait  
for approx. 2 to 3 minute, and the operation will be automatically changed  
to the ordinary heating mode.  
Defrosting operation (in the heating mode):  
When it is liable to frost. the heating operation is stopped automatically  
for 5 to 12 minutes once per approx. one hour, and defrosting is operated.  
After defrosting is completed, operation mode is automatically changed  
to ordinary heating operation.  
When the room thermostat is actuated:  
When room temperature increases and room temperature controller actu-  
ates, the fan speed is automatically changed to stop under low temperature  
condition of indoor heat exchanger. When room temperature decreases,  
air conditioner automatically changes over to ordinary heating operation.  
WARMING OPERATION  
Heat pump type warming  
With the heat pump type warming, the mechanism of heat pump that concentrate heat of outdoor  
air with the help of refrigerant to warm the indoor space, is utilized.  
Defrosting operation  
When a room is warmed with a heat pump type air conditioner, frost accumulates on the heat ex-  
changer of outdoor unit along with the drop of indoor temperature. Since the accumulated frost re-  
duces the effect of warming, it is necessery to automatically switch the operation to the defrosting  
mode. During the defrosting operation, heating operation is interrupted.  
Atmospheric temperature and warming capacity  
Warming capacity of heat pump type air conditioner decreases along with the  
drop of outdoor temperature.  
When the warming capacity is not sufficient, it is recommended to use another  
heating implement.  
Period of warm-up  
Since the heat pump type air conditioner employs a method to circulate warm  
winds to warm the entire space of a room, it takes time before the room tem-  
perature rises.  
It is recommendable to start the operation a little earlier in a very cold morning.

For details consult your sales dealer.  
Electric work  
The electric work must be burden on the authorized engineer with qualification for electric work and  
grounding work, and the work must be conducted in accordance with electric equipment technical standard.  
The power source for the unit is to be of exclusive use.  
An earth leakage breaker should be installed.(This is necessary to prevent electric shock.)  
The unit must be grounded.  
When you change your address or the installation place  
Special technology is required for removal or reinstallation of air conditioner, consult the sales dealer.  
Besides, construction expense is charged for removal or reinstallation.  
For inspection and maintenance  
The capacity of air conditioner will decrease by contamination of inside of unit when it is used for about  
three years although depending upon the circumstances under which it is used, and so in addition to the  
usual maintenance service, special inspection/maintenance service is necessary. It is recommended to  
make a maintenance contract (charged) by consulting your sales dealer.

Please read these "Safety Precautions" first then accurately execute the installation work.  
Though the precautionary points indicated herein are divided under two headings,  
WARNING  
and  
resulting in death or serious injury are listed in the  
possibility of serious consequences in relationship to the points listed in the  
, those points which are related to the strong possibility of an installation done in error  
section. However, there is also a  
section as well.  
CAUTION  
WARNING  
CAUTION  
In either case, important safety related information is indicated, so by all means, properly observe all that is  
mentioned.  
After completing the installation, along with confirming that no abnormalities were seen from the operation  
tests, please explain operating methods as well as maintenance methods to the user (customer) of this equipment,  
based on the owner's manual.  
Moreover, ask the customer to keep this sheet together with the owner's manual.  
WARNING  
This system should be applied to places as office, restaurant, residence and the like. Application to inferior  
environment such as engineering shop could cause equipment malfunction.  
Please entrust installation to either the company which sold you the equipment or to a professional contractor.  
Defects from improper installations can be the cause of water leakage, electric shocks and fires.  
Execute the installation accurately, based on following the installation manual. Again, improper installations  
can result in water leakage, electric shocks and fires.  
When a large air-conditioning system is installed to a small room, it is necessary to have a prior planned  
countermeasure for the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration.  
In regards to preparing this countermeasure, consult with the company from which you perchased the equipment,  
and make the installation accordingly. In the rare event that a refrigerant leakage and exceeding of threshold  
concentration does occur, there is the danger of a resultant oxygen deficiency accident.  
For installation, confirm that the installation site can sufficiently support heavy weight. When strength is  
insufficient, injury can result from a falling of the unit.  
Execute the prescribed installation construction to prepare for earthquakes and the strong winds of typhoons  
and hurricanes, etc. Improper installations can result in accidents due to a violent falling over of the unit.  
For electrical work, please see that a licensed electrician executes the work while following the safety standards  
related to electrical equipment, and local regulations as well as the installation instructions, and that only  
exclusive use circuits are used.  
Insufficient power source circuit capacity and defective installation execution can be the cause of electric  
shocks and fires.  
Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted  
to the terminal connection part, through properly securing it. Improper connection or securing can result in  
heat generation or fire.  
Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper installation  
can also result in heat generation or fire.  
When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the  
designated refrigerant (R410A) within the refrigeration cycle.  
Rupture and injury caused by abnormal high pressure can result from such mixing.  
Always use accessory parts and authorized parts for installation construction. Using parts not authorized by  
this company can result in water leakage, electric shock, fire and refrigerant leakage.  
CAUTION  
Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightning rod or a  
telephone ground wire. Improper placement of ground wires can result in electric shock.  
The installation of an earth leakage breaker is necessary depending on the established location of the unit.  
Not installing an earth leakage breaker may result in electric shock.  
Do not install the unit where there is a concern about leakage of combustible gas.  
The rare event of leaked gas collecting around the unit could result in an outbreak of fire.  
For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally insulate  
it to prevent condensation. Inadequate plumbing can result in water leakage and water damage to interior  
items.

(b)  
(c)  
When connecting the drain pipe to unit, pay suffcient  
attention not to apply excess force to the  
piping on the unit side. Also, fix the piping at a  
point as close as possible to the unit.  
For drain pipe, use hard PVC general purpose pipe  
VP-25(I.D.1") which can be purchased locally. When  
connecting, insert a PVC pipe end securely into the  
drain socket before tightening securely using the  
attached drain hose and clamp. Adhesive must not  
be used connection of the drain socket and drain  
hose (accessory).

Installation Manual For Indoor Unit  
Secure the elevation as high as possible  
(approx. 100 mm)  
(d) When constructing drain piping for several units, position the  
common pipe about 100 mm below the drain outlet of each  
unit as shown in the sketch. Use VP-30(11/4") or thicker pipe  
for this purpose.  
VP 30  
A downhill grade of  
1/100 or more  
(e)  
Be sure to provide heat insulation to hard PVC pipes of indoor  
placement.  
290~325mm  
Do not ever provide an air vent.  
(f)  
(g)  
Right overhead  
The height of the drain head can be elevated up to a point 500  
mm above the ceiling, and when an obstacle exists in the  
ceiling space, elevate the piping to avoid the obstacle using  
an elbow or corresponding gadget. When doing this, if the  
stretch for the needed height is higher than 500 mm, the back-  
flow quantity of drain at the event of interruption of the  
operation gets too much and it may cause overflow at the  
drain pan. Therefore, make the height of the drain pipe within  
the distance given in the sketch below.  
Drain hose  
Joint for VP 25  
(Local procurement)  
Avoid positioning the drain piping outlet at a place where  
generation of odor may be stimulated. Do not lead the drain  
piping direct into a sewer from where sulfur gas may generate.

Conduct a drainage test after completion of the electrical work.  
During the trial, make sure that drain flows properly through the piping and that no water leaks  
from connections.

In case of a new building, conduct the test before it is furnished with the ceiling.  
Be sure to conduct this test even when the unit is installed in the heating season.  
Procedures

Supply about 1000 cc of water to the unit through the air outlet using a feed water pump.  
Check the drain while cooling operation.  
Pour water into a convex joint.  
Insert water supply hose  
for 20 mm ~ 30 mm to  
supply water.  
(Insert hose facing  
toward bottom.)  
(In the electrical work has not been completed,  
connect a convex joint in the drain pipe connection
