Heating Mode

"HOT KEEP" function

"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 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
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 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 temperature rises.
It is recommendable to start the operation a little earlier in a very cold morning.

Precaution for Installation

Please read these "Safety Precautions" first and then accurately execute the installation work.
Though the precautionary points indicated herein are divided under two headings, and , those
points which 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 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
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.

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,please refer to the digram and select
drain pipe size according to drain opening inner diameter size.
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 pipeuse 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

(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.

(f)

The hard PVC pipe put indoor side should be heat insulated. Do
not ever provide an air vent.

(g)

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.

Avoid positioning the drain piping outlet at a
