Please read the following safety instructions before installation. And ensure that the unit is installed
correctly.
Please observe all instruction in order to avoid any injury or damage to equipment or property.
The following symbols indicate potential levels of caution.
Situations with a risk or death or
serious injure. Situations with a risk of injury or
equipment/property damage.
The following symbols indicate compliance which must be observed
Not allowed or Stop Must follow or obliged
Safety attentions
Installation to be carried out by qualified
person, End Users must not install, move or
re-install this equipment by themselves
An anti-bird net or similar device should be
installed to outside vents. Ensure there are
no obstructions to or in the ducts
Installation engineers must follow this man-
ual strictly. Improper action can create a
health hazard and reduce efficiency of the
unit
Fresh air vent must be far enough away
from any flue gas discharge or areas where
hazardous vapors are present
Unit must be installed strictly following this
manual and mounted to a weight bearing
surface for the weight of the unit
Electric engineering must follow national
regulations and the manual, use special ca-
bles. Less capacity cables and improper en-
gineering can cause electric shock or fire.
During maintenance or repair, the unit and
circuit breaker must be switched off. Other-
wise electric shock could occur.
Ground wire cannot be connected to gas
pipe, water pipe, lighting rod or telephone
line etc. Incorrect grounding can cause
electric shock.

Safety Considerations
mepokerkft.hu

Do not install the unit in an extremely hu-
mid conditions, as it may result in electric
shock and pose a fire risk.
Do not use the units as the primary kitchen
extract grease and fatty deposits can block
the heat exchanger, filter and pose a fire
risk.
Don not install the unit in areas there any
poisonous or caustic gases are present.
Do not install the unit near open flame as it
may result in over heating and pose a fire
risk
Acidic or alkali environments can cause poi-
soning or a fire Rated supply voltage must be maintained,
otherwise this may cause fire.
Power cable and wires must be installed by
a qualified electrical engineer. Improper
connection can cause over heating. Fire and
loss of efficiency.
To avoid condensation, insulation should be
fitted to fresh air ducts. Other ducting may
also require insulation depending on dew
point conditions.
Insulation between the metal ducting and
wall penetration must be installed if the
ducting penetrates metal wall cladding, to
avoid risk of electric shock or current leak-
age.
The cover of wiring box must be pressed
down and closed to avoid dust and dirt en-
tering. Excess dust and dirt can cause over-
heating of terminals and result in fire or
electric shock.
Use only approved installation hardware
and accessories. Failure to observe can re-
sult in fire risk, electric shock and equip-
ment failure
Where the unit is positioned, at high level in
a hot humid situation. Please ensure suffi-
cient ventilation is available
The outdoor ducts must be installed facing
downwards to avoid rain water entering.
Improper installation can cause water leak-
age.
Correctly sized MCB must be fitted to the
unit suitable earth leakage protection
should also be installed to avoid risk of elec-
tric shock or fire.

Installation Considerations
mepokerkft.hu

Serve bends Multiple reducers/ crimped duct
Multiple direction changes
3. Unit must not be installed close to boiler flues.
4. Following phenomenon should be avoided in the ducting installation.
5. Excessive use of flex-duct and long flex-duct runs should be avoided.
6. Fire dampers must be fitted as per national and local fire regulations.
7. Unit must not be exposed to ambient temperature above 40℃ and should not face an open fire.
8. Take action to avoid dew and frost.
As shown by drawing below, unit will produce dew or frost when saturation curve is formed from A to C.
Use pre-heater to ensure conditions are kept to right of the curve (B to B',to move C to C) to prevent
condensation or frost formation.
9. To avoid the outdoor exhaust air cycling back to indoor, the distance between the two vents installed
on the outside wall should be over 1000mm.
10.If heater is equipped to the unit, operation of heater should be synchronous with the unit, so that the
heater starts to work only when unit starts.
11.Duct muffler may be considered if user wants indoor noise to be minimized.

Installation Considerations
mepokerkft.hu

Ducting
1. Connection of unit vents and ducts should be taped or sealed to prevent air leakage, and should
comply to relevant guidelines and regulations.
2. The two outdoor vents should face downward toward the outside to prevent any rain water ingress.
(angle 1/100 1/50).
3. Insulation must be with the two ducts outside to prevent condensation.

Installation Considerations
mepokerkft.hu

Power must be isolated during installation and before maintenance to avoid injury by electric shock.
The specifications of cables must strictly match the requirements, otherwise it may cause performance
failure and danger of electric shock or fire.
Power supply is AC220V/50HZ/1 Phase. Open the cover of electrical box, connect the 3 wires (L/N/
GND) to the terminals and connect the cable of the control panel to the board according to the wiring
diagram, and join the control panel to the cable. A cable fixing device offered by installer is recom-
mended to fix the power cable on the wall/ventilator.
We do not accept any liability for any problems caused by the user’s self and non-authorized re-
engineering to the electrical and control systems.

Electrical Installation
mepokerkft.hu

Loose or incorrect wiring connection can
cause explosion or fire when the unit starts
to work. Use only rated power voltage.
Don’t put fingers or objects into vents of
fresh air or exhaust air supply. Injury may
be caused by the rotation of the impeller.
Don’t install, move or re-install the unit by
yourself. Improper action may cause unit
instability, electric shock or fire.
Don’t change, disassemble or repair the
unit by yourself. Improper action may cause
electric shock or fire.
Running the unit continuously in an abnormal
status may cause failure, electric shock or
fire.
Switch off the power and breaker when you
clean the exchanger.
Don’t site intake supply vent in hot and hu-
mid
conditions , as it may cause failure, current
leakage or fire.
Don’t put any burner directly facing the
fresh air discharge, otherwise it may cause
an insufficient burning.
Isolate power during extended off periods
Isolate power and take care when cleaning
unit. (Risk of electric shock)
Observe guidelines and regulations relating
to incomplete combustion when use is asso-
ciated with fuel burning appliances.
Clean the filter regularly. A blocked filter may
result in poor indoor air quality.
Commissioning
1. Check the wiring after the installation works are completed, and there must be commissioning.
2. Turn on the power supply, and carry out the commissioning and operation according to controller
instructions. Check the working conditions of the blower, exhaust fan and bypass. The motor will stop
running for more than 10 seconds when the bypass valve of the ventilator is operating.
3. When abnormalities occur in commissioning, it can be thought that the connection is wrong. To
prevent electric shock, please turn off the special circuit breaker immediately and reconnect the wire

Conventional defrosting: when the EA temperature lower than the setting defrost temperature (the
preset value is 1℃) and lasts for 1 minute, and it has been exceed the defrosting interval (the preset
value is 30 minutes), the supply fan will stop and exhaust fan run at high speed, until the EA tempera-
ture is +15℃ and lasts for 1 minute, or the defrosting has been lasting for a certain time (i.e. defrost-
ing duration, whose preset value is 10 minutes), then the ventilator will turn back to the original op-
eration state.
