SAFETY CONSIDERATIONS
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�
Safety attentions
The following symbols indicate potential levels of caution�
The following symbols indicate compliance which must be observed
Warning
Attention
Installation to be carried out by qualied
person, End Users must not install, move or re-install this equipment by themselves�
Power cable and wires must be installed
by a qualied electrical engineer. Improper
connection can cause over heating� Fire and
loss of efciency.
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 leakage�
Use only approved installation hardware and accessories� Failure to observe can result in re risk, electric shock and equip­ment failure�
The outdoor ducts must be installed facing downwards to avoid rain water entering� Improper installation can cause water leakage�
Where the unit is positioned, at high level in
a hot humid situation. Please ensure sufcient
ventilation is available�
Correctly sized MCB must be tted to the
unit suitable earth leakage protection should also be installed to avoid risk of electric shock
or re.
The cover of wiring box must be pressed down and closed to avoid dust and dirt ente­ring� Excess dust and dirt can cause over-hea-
ting of terminals and result in re or electric
shock�
Installation engineers must follow this man­ual strictly� Improper action can create a
health hazard and reduce efciency of the
unit�
Unit must be installed strictly following this manual and mounted to a weight bearing surface for the weight of the unit�
During maintenance or repair, the unit and circuit breaker must be switched off� Other-wise electric shock could occur�
An anti-bird net or similar device should be installed to outside vents� Ensure there are no obstructions to or in the ducts�
To avoid condensation, insulation should be
tted to fresh air ducts. Other ducting may
also require insulation depending on dew point conditions�
Fresh air vent must be far enough away
from any ue gas discharge or areas where
hazardous vapors are present�
Electric engineering must follow national regulations and the manual, use special cables� Less capacity cables and improper enginee-
ring can cause electric shock or re.
Ground wire cannot be connected to gas pipe, water pipe, lighting rod or telephone line etc� Incorrect grounding can cause electric shock�
Not allowed or Stop
Must follow or obliged
Situations with a risk of injury or equipment/ property damage�
Situations with a risk or death or serious injure�

Attention
Do not install the unit in an extremely hu­mid conditions, as it may result in electric
shock and pose a re risk.
Don not install the unit in areas there any poisonous or caustic gases are present�
Acidic or alkali environments can cause
poisoning or a re.
Do not use the units as the primary kit­chen extract grease and fatty deposits can
block the heat exchanger, lter and pose a re risk.
Do not install the unit near open ame as it may result in over heating and pose a re
risk�
Rated supply voltage must be maintained,
otherwise this may cause re.

INSTALLATION CONSIDERATIONS
Installation Considerations
Protect the unit to avoid dust or other obstructions entering the unit and accessories during installation, or
whilst in storage on site. Service ports should be installed to allow access for lter maintenance.
1� Be sure the ceiling height is no less than the Figures in above table B column�
2. Unit must not be installed close to boiler ues.
3� Following phenomenon should be avoided in the ducting installation�

INSTALLATION CONSIDERATIONS
4.Exessive use of ex-duct and long ex-duct runs should be avoided.
5.Fire dampers must be tted as per national and local re regulations.
6.Unit must not be exposed to ambient temperature above 40°C and should not face an open re.
7�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.
8� 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� 9�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�
10.Duct mufer may be considered if user wants indoor noise to be minimized.
