FEATURES
1. NEXT GENERATION AIR-CONDITIONING VENTILATION INTERLOCKING SYSTEM "Mr.SLIM"+
"LOSSNAY"
Proper ventilation is important to improve the quality of indoor environments. It eliminates unclean air, which is not only
unpleasant, but unhealthy. This "Mr.SLIM" + "LOSSNAY" ventilation interlocking system achieves high air quality with
minimum energy consumption.
LOSSNAY's unique total heat exchanger reduces heating and cooling expenses by about 25 percent annually(in
comparison with our existing models). In addition, its mechanism of simultaneous forced air supply and exhaust enables it
to deliver high quality air.
Together, "Mr.SLIM" + "LOSSNAY" system makes next-generation air conditioning possible. This system is both people
and environment friendly.
2. TOTALLY INVISIBLE INDOOR UNIT BEHIND THE CEILING
The totally hidden indoor unit that lies above the ceiling surface enables you to utilize full floor space while allowing for
flexible interior design. This new feature is recommended for stores and offices where the user's own imagination is
allowed to be incorporated.
3. MOST SUITABLE FOR SIMULTANEOUS TWO ROOM AIR CONDITIONING
Using air ducts for cooling/heating airflow that matches the structure and purpose of the room enables you to provide two
air outlets for simultaneous cooling/heating of two rooms.
4. HIGH EXTERNAL STATIC PRESSURE(OPTION MOTOR)
The exceptional external static pressure of 130Pa allows long ducts to be used more extensively to achieve convenient
location of indoor units.(STD:70Pa)
5. DRAIN WATER LIFT-UP MECHANISM(OPTION KIT)
This allows more versatility when selecting drain piping layouts.

PART NAMES AND FUNCTIONS
6. ADVANCED MICROPROCESSOR
(1) Easy to use microprocessor
1) Ultra-thin remote controller
The streamlined, square controller is designed to blend well with any interior. Also, the sophisticated microprocessor allows you to easily carry out a wide range of operations.
2) Attractive liquid crystal display (LCD)
The unit's operation mode, set temperature, room temperature, timer setting, and fan speed are displayed on the
remote controller's easy-to-read Liquid Crystal Display (LCD)
3) Convenient 24-hour ON-OFF timer
The timer switches Mr.SLIM on and off automatically at the time you set. Once the timer is set, the remaining time
is shown on the LCD.
4) Self-diagnostic feature indicates faults instantly
If a problem occurs, the unit will stop operating and the set temperature indicator will change to a self-diagnostic
indicator, which shows the location of the trouble.
If the check switch is pressed twice, the unit stops operating and the check mode is initiated. The location of the
most recent problem that was stored in the memory is displayed on the LCD. This is extremely useful for
maintenance purposes.
5) Useful memory feature for storing instructions
The previous set value is memorized so that constant temperature control can be achieved. For example, if a
power failure occurs, the temperature will not have to be re adjusted afterwards.
(2) Non-polar two-wire remote controller cable
The slim, non-polar, two-wire remote controller cable makes installation simple and trouble free. Also, the remote
controller wire can be extended up to 500m.
(3) Automatic cooling/heating changeover operation
An automatic cooling and heating changeover operation system allows you to easily control comfortable year-round
air conditioning.
Once the desired temperature is set, unit operation switches automatically between cooling and heating, in
accordance with the room temperature. In addition, the use of an outdoor unit fan speed controller allows cooling even
when outdoor temperatures are as low as - 5˚C.
7. INNOVATIVE MICROPROCESSOR CONTROL SYSTEM
The most significant feature of PEHD-EK series is the advanced microprocessor control. The development of this system
is due to the recent world-wide trend in the air conditioning of larger buildings. They are moving away from centralized
duct systems to using individual split type units instead. There are a number of reasons for this change. First of all, the
duct's costly and troublesome installation is eliminated. Second, the overall air conditioning balance is excellent in split
type units. Lastly, the operation costs are low due to the flexible control of each unit. This system was developed
exclusively by Mitsubishi Electric because of high demand. The microprocessor control makes individual control, group
control, control using two remote controllers, and remote on/off and individual control possible without troublesome
equipment modifications.

[ Check items]
(1) Make sure that no other trouble exists with the outdoor unit.
Trouble with the outdoor unit prevents emergency operation.
(If any trouble exists with the outdoor unit,the trouble
location will be displayed on the remote controller and
the trouble position will be shown on the outdoor controller board LED.See electric circuit diagram of the outdoor
unit for details.)
(2) Make sure that there is no trouble with the indoor fan.
Emergency operation will be a continuous run with operation
by the power ON/OFF.
(ON/OFFwith the remote controller is not possible).
[Emergency operation procedure ]
(1) Set the dip switch(SW3<I.B>)on the indoor controller board
to 1 · 2 · 3 on and 4 off for cooling, and 2 · 3 · 4
on and 1 off for heeting.
(2)Turn on the outdoor unit side circuit breaker.
(3) During emergency operation indoor fan runs at High speed.
(4)Thermostat will not function.Cold air blows out for defrosting
during heating thus do not operate defrosting for a long time.
(5) Emergency cooling should be limited to 10 hours maximum
(the indoor unit heat exchanger may freeze).

For model:PEHD-4EK(H)SA3.UK, PEHD-5EK(H)SA3.UK, PEHD-6EK(H)SA.UK
Note 1.How to connect refrigerant pipes.
Factory supplied optional piping contains refrigerant at above atmospheric pressure. As long as the connection
takes no more than 5 minutes, no air will enter, and there will be no need for air purging.
Remove the blind caps and make the connections within 5 minutes. After the connections for the indoor and
outdoor units are made, open the stop valve on the outdoor unit to allow refrigerant gas to flow.
If piping length exceeds 5m, an additional charge of refrigerant is needed.
Note 2.The following main parts are contained in the optional refrigerant piping kit.
Heat insulating cover, vinyl tapes, nipples, sleeve and flange(for wall hole), connecting cables,
