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 qualied
person, End Users must not install, move or
re-install this equipment by themselves.
Power cable and wires must be installed
by a qualied electrical engineer. Improper
connection can cause over heating. Fire and
loss of efciency.
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 equip-
ment 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 sufcient
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 ente-
ring. Excess dust and dirt can cause over-hea-
ting of terminals and result in re or electric
shock.
Installation engineers must follow this man-
ual strictly. Improper action can create a
health hazard and reduce efciency 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 hu-
mid conditions, as it may result in electric
shock and pose a re risk.
Do 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 kit-
chen 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
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.The Mark ERV is only suitable as a decentralized heat recovery unit with max. 3-5 meters preferably
straight ductwork.The situations below should be avoided. If this advice is deviated from, the maximum
air ow rate of the unit will not be achieved.
4. Excessive 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.
Serve bends Multiple direction changes Multiple reducers/
crimped duct
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 mufer may be considered if user wants indoor noise to be minimized.

INSTALLATION CONSIDERATIONS
Physical Installation
1. Installer to prepare suitable threaded hangers with adjustable nuts and gaskets.
2. Install as shown by the image above. Installation must be level and securely fastened.
3. Failure to observe proper xing could result in injury, equipment damage and excessive vibration.
Uneven installation will also effect damper operation.
Notes for reverse installation of the unit
4. Reverse labeling shows the unit is upside down.
Ducting
1. Connection of unit vents and ducts should be taped or sealed to prevent air leakage, and should com-
ply 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.
