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
Situations with a risk or death or
serious injure.
Not allowed or Stop
Situations with a risk of injury or
equipment/property damage.
Must follow or obliged
Installation to be carried out by qualified
person, End Users must not install, move or
re-install this equipment by themselves
Installation engineers must follow this manual strictly. Improper action can create a
health hazard and reduce efficiency 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. Otherwise 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
Fresh air vent must be far enough away
from any flue 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 engineering can cause electric shock or fire.
Ground wire cannot be connected to gas
pipe, water pipe, lighting rod or telephone
line etc. Incorrect grounding can cause
electric shock.
Power cable and wires must be installed by
a qualified electrical engineer. Improper
3
connection can cause over heating. Fire and
loss of efficiency.
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 fire 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.
To avoid condensation, insulation should be
fitted to fresh air ducts. Other ducting may
also require insulation depending on dew
point conditions.
The cover of wiring box must be pressed
down and closed to avoid dust and dirt entering. Excess dust and dirt can cause overheating of terminals and result in fire or
electric shock.
Where the unit is positioned, at high level in
a hot humid situation. Please ensure sufficient ventilation is available
Correctly sized MCB must be fitted to the
unit suitable earth leakage protection
should also be installed to avoid risk of electric shock or fire.
Safety Considerations
Safety Considerations
Do not install the unit in an extremely humid conditions, as it may result in electric
shock and pose a fire risk.
Don not install the unit in areas there any
poisonous or caustic gases are present.
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.
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
poisoning or a fire
Rated supply voltage must be maintained,
otherwise this may cause fire.
