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 actuates, 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 exchanger of outdoor unit
along with the drop of indoor temperature. Since the accumulated frost reduces the effect of warming, it is necessary 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 temperature rises.
It is recommendable to start the operation a little earlier in a very cold morning.

Though the precautionary points indicated herein are divided under two headings, and , those
points which are related to the strong possibility of an installation done in error resulting in death or serious injury are
listed in the section. However, there is also a possibility of serious consequences in relationship to the
points listed in the section as well. 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.
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 purchased 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.

(b) When connecting the drain pipe to unit, pay sufficient
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.
(c) For unit without water pump, the drain pipe shall be slant
downwards (greater than 1/100).
The horizontal length of the drain pipe shall be less than
20 m. In case of long pipe, supports shall be provided every
1.5~2m to prevent wavy form.
Central piping shall be laid out according to the right figure.
Take care not to apply external force onto the drain pipe
connection part.
(d) For unit with water pump drain pipe use hard PVC general
purpose pipe VP 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 for connection
of the drain socket and drain hose (accessory).

Installation Procedure
Drain Pipe
(e) 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.
Secure the elevation as high as possible (approx. 100 mm)
VP-30
A downhill grade of 1/100 or more
(f) The stiff PVC pipe put indoor side should be heat insulated.
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.
290~325mm
Taking the ADH**H serials as an example, the installation
of the drain pipe is the following.
Use general hard polyvinyl chloride (VP25) and connect it
with adhesive (polyvinyl chloride) so that there is no leakage.
Do not perform air bleeding.

(g) 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.
(h) Because the drain spout is at the position, which negative
pressure may occur. So with the rise of water level in the
drain pan, water leakage may occur. In order to prevent water
leakage, we designed a backwater bend. The structure of
backwater bend should be able to be cleaned. As the below
figure shown, use T type joint. The backwater bend is set
near the air conditioner.
As figure shown, set a backwater bend in the middle of drain
hose.

During the trial, make sure that drain flows properly through the
(2)
piping and that no water leaks from connections.
In case of a new building, conduct the test before it is furnished
(3)
with the ceiling.
Be sure to conduct this test even when the unit is installed in the
(4)
heating season.
Drain Pipe
Insert water supply hose
for 20 mm ~ 30 mm to
supply water.
(Insert hose facing
toward bottom.)
Remove grommet.
Make sure to install
it back after test.
Procedures
(a)
Supply about 1000 cc of water to the unit through the air outlet
using a feed water pump.
(b)
Check the drain while cooling operation.
Before the electrical work has not been completed, connect a convex
joint in the drain pipe connection to provide a water inlet. Then, check
if water leaks from the piping system and that drain flows through
the drain pipe normally.
