GENERAL INFORMATION
1.1.1
Specific features
The “Mitsubishi Daiya” room air conditioner: SRK series are of split and wall mounted type and the unit consists of indoor unit
and outdoor unit with refrigerant precharged in factory. The indoor unit is composed of room air cooling or heating equipment with
operation control switch and the outdoor unit is composed of condensing unit with compressor.
(1) Remote control flap
The flap can be automatically controlled by operating wireless remote control.
¡
AUTO (Natural flow) :
Flap operation is automatically control.
¡
Swing
This will swing the flap up and down.
¡
Memory flap :
:
Once the flap position is set, the unit memorizes the position and continues to
operate at the same position from the next time.
(2) Automatic Operation
When the remote control switch is set on “auto”, it will either automatically decide operation mode such as cooling,
heating and thermal dry, or operate in the operation mode before it has been turned to automatic control.
(3) Self diagnosis Function
We are constantly trying to do better service to our customers by installing such judges that show abnormality of operation
as follows.
t

Content
Low input rotary compressor with high efficiency is equipped.
All operation modes can be operated from distance place by the wireless remote control. And also liquid crystal is used to show all kinds to
operation or, off, air flow switch, operation switch, timer switch, timer
set, temperature set, flap control.
Defumidifies while keeping room temperature to the thermostat setting
level by M.C. thermostat.
ON timer setting for anytime during 24 (32, 40: 12) hours can be performed.
OFF timer setting for favourite time can be performed. Comfortable
Cooling and Dry operation to prevent catching cold in sleep and economical operation can be performed, while raising room temperature
setting during 1 hour period in steps.
While COOL & DRY: When the timer is set to OFF the temperature is
increased by 0.5ºC simultaneously, by 0.5ºC additionally every 30
minutes and by 1.5ºC in one hour.
While HEAT: When the timer is set to OFF the temperature is decreased by 1ºC simultaneously by 1ºC additionally every 30 minutes
and by 3ºC in one hour. (Heat Pump type only)
Room unit air volume can be automatically controlled step by step,
according to the difference between room temperature and setting temperature.
1. Shorten pull down time for cooling/heating operation
2. Low noise level operation can performed by proper air volume.
When heating is initiated, thermostat reset, or heating resumed after defrosting, the indoor fan is automatically controlled
stop to set value in accordance with the temperature of the indoor air
heat exchanger to prevent the blowing out of cold air.
The thermostat temperature setting is automatically increased by 2ºC when heating is initiated to provide faster stabilization of room temperature.
The indoor fan is stopped depending on the temp, of the indoor heat
exchanger to prevent the blowing-out of cold air when the
heating operation is stopped by thermostat or defrosting
operation is started.
The change in the difference between the intake air temperature and the
heat exchanger temperature causes the frost and condensation removal
operation to start.
M. C thermostat improves on energy saving and comfort, by controlling room temperature with high accuracy.
The flap can be automatically controlled by operating wireless remote
control.
• AUTO (Natural flow) : Flap operation is automatically controlled.
• Swing
: This will swing the flap up and down.
• Memory flap
: Once the flap position is set, the unit memorizes the position and continues to operate at
the same position from the next time.
The room temperature is checked 60 minutes before the timer is at ON.
Depending on the temperature at that time, the operation starets 5 to 60
minutes before the timer is at ON.
We are constantly trying to do better service to our customers by installing such judges that show abnormality of each function as follows:
• Abnormality of outdoor unit:
TIMER lamp flashing.
• Abnormality of indoor fan motor:
RUN lamp flashing.
• Abnormality of heat exchanger thermistor: No lamp will flashing

Additional refrigerant charge
When refrigerant piping exceeds 7(40 : 7.5) m conduct additional refrigerant charge after refrigerant sweeping.
S 50, 56 models
7m over 15m
: Additional charge amount per meter = 20g/m
S 40 model
Max. 10m
: Additional charge amount per meter = 20g/m
10m over 15m : Additional charge amount per meter = 30g/m
[Example : 50 model]
How much amount of additional charge for 15m piping?
(15 – 7)m × 20g/m = 160g
160g for additional charge
(4) Insulation of connecting portion
1)
Cover the connection portion of the refrigerant piping with
To cover the connecting portion with
insulation materials, cut upper portion and
then seal it with insulation materials.
Vinyl tape

If neglecting to do so, moisture occurs on the piping and
water will drip out.

Finishing and fixing
a)
Tie up the piping with wrapping tape, and shape it so
that it conforms to which the pipe is attached.
b)

Fix them with clamps as right figure.
Cover the exterior portion with
covering tape and shape the piping
so it will match the contours of the
route that the piping to take. Also
fix the wiring and pipings to the
wall with clamps.
Tapping screw
Test run
(1) Conduct trial run after confirming that there is no gas leaks.
(2) When conducting trial run set the remote controller thermostat to continuous operation position. However when the power source
is cut off or when the unit’s operation switch is turned off or was turned to fan operation position, the unit will not go into operation
in order to protect the compressor.
(3) Insert in electric plug into the electric outlet and make sure that it is not loose.
(a)
When there is something wrong with the electric outlet and if the insertion of the electric plug is insufficient, there may occur
a burn out.
(b)
It is very important to be careful of above when pulgging in the unit to an already furnished electrical outlet.
(4) Explain to the customer on the correct usage of the air conditioner in simple layman’s terms.
(5) Make sure that drain flows properly.

Trouble shooting
(1) Trouble shooting to be performed prior to exchanging PCB, (Printed circuit board) [Common to all models]
All the models described in this chapter are controlled by a microcomputer. When providing maintenance service to customers it
is necessary to understand the function controlled by a micro computer thoroughly, so as not to mistakenly identify correct operations as mis-operations. It is also necessary to perform the following simple checks before conducting detailed checks or exchanging printed circuit board.
Before exchanging Printed circuit board
Claim call from the user
Ascertain the nature of the claim.
Unit did not cool, etc.
¡ Is the power on?
¡ Is the thermostat setting correct?
(Not too high?)
¡ Is the unit in a timer operation?
¡ Does user understand function?
etc.
Ascertain the operation status.
Is this nonsense claim?
YES
No
Operate the unit.
¡ Explain the function of the unit to user.
Does the trouble occur again?
No
No need for PCB change
Check further the status when the trouble occured
(such as the timer of occurence, power failures, thunder, use status of other electrical appliances, etc).
