It smells.
During operation,
white fog comes
out of indoor unit.
It is switched into the FAN mode
during cooling.
The air conditioner can not be
restarted soon after it stops.
Unit does
not start
When the air conditioner is started, when the compressor starts or
stops during operation or when the air conditioner is stopped, it
sometimes sounds "shuru shuru" or "gobo gobo". It is the flowing
sound of the refrigerant, and it is not a trouble.
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.
In this case consult sales dealer for cleaning the heat exchanger.
To prevent frost from being accumulated on the indoor unit heat
exchanger, it is sometimes automatically switched to the FAN mode
but it will soon return to the cooling mode.
Even if the operation switch is turned on, cooling, dehumidifying
or heating is not operable for three minutes after the conditioner is
stopped. Because the protecting circuit is activated.

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 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 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.
10

(f)
(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 backflow 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 place where
(h)
generation of odor may be stimulated. Do not lead the drain
piping direct into a sewer from where sulfur gas may generate.
Drainage Test
1
Conduct a drainage test after completion of the electrical work.
2
During the trial, make sure that drain flows properly through the piping and that no water leaks
from connections.
3
In case of a new building, conduct the test before it is furnished with the ceiling.
4
Be sure to conduct this test even when the unit is installed in the heating season.

Calculate the draft and external static pressure and select the length, shape and blowout.
A Blowout duct
2-spot, 3-spot and 4-spot with 200 type duct are the standard specifications. Determine the
number of spots based on following table.
Note (1) Shield the central blowout hole for 2-spot.
(2) Shield the blowout hole around the center for 3-spot.
Limit the difference in length between spots at less than 2:1.
Reduce the length of duct as much as possible.
Reduce the number of bends as much as possible. (Corner R should be as larger as possible.)
