• Consult the ventilation planner regarding possible
need for additional insulation of the unit if
mounted in a cold space.
• If you use solid (hard) insulation, make sure
that the insulation does not carry sound to the
frame of the house.
• Do not install the unit in spaces with high
temperature and high humidity level.
• In certain conditions these can cause
condensation on the unit’s outer shell.
• Consider the unit noise level when choosing the
installation location.
• Do not install the ventilation unit directly
outside a bedroom, since even though the
ventilation unit is quiet, it is never completely
silent.
• Set the unit on top of a soundproong 100 mm
insulation.
• Make sure that it is possible to connect the
condensate water drain and water lock.
• Consider the space needed for the condensate
water connection.
• Make sure that you install re shuto valves if the
unit is placed in a separate re area.
• Consider the unit maintenance tasks when
installing the unit.
• Make sure that there is enough space in front
of or above the maintenance hatch:
Unit Free space in front of the hatch
LTR-2 and LTR-3 min. 50 cm
LTR-4 and LTR-6 min. 60 cm
LTR-7 and LTR-7 XL min. 70 cm
• Make sure that the electrical connections can be
easily accessed.
• Take into account the space needed for opening
the maintenance hatch locking latches.
• Consider the space needed for duct coils (if
included).
BUILDING THE VENTILATION
SYSTEM
Designing the ventilation system must be done by a
professional ventilation designer. By following closely
the design plan when building the ventilation system,
you ensure the operation of the whole ventilation
system and customer satisfaction. Use the Enervent
Energy Optimizer calculation program at the Enervent
home page to calculate the performance and estimated
heating/cooling power of a particular ventilation unit.
• Use type-approved factory made materials when
building the ventilation system.
• Use valves that are suitable for mechanical
ventilation.
• Do not cover the outside air grating with mosquito
net.
• This would make it very dicult to keep clean.
• Prevent rain water and snow from entering the
outside air and exhaust air duct.
• Install enough inspection hatches in the
ventilation network to enable cleaning of the
ventilation ducts.
• To make it easier to nd the inspection
hatches, mark their location for example on
the rafters.
• Ventilation systems for dierent re areas must be
separate.
• For example garage is one re area whereas
living quarters are another re area, which
means that they cannot be connected to the
same ventilation system.
• Use an extractor hood with its own fan, above the
stove.
• The extractor hood must have its own extract
duct directly out.
• A motorless extractor hood can be connected
to the ventilation unit only if the ventilation
unit has an extractor hood connection.
• The extractor hood used must be equipped
with a grease lter and a timer controlled ap
that prevents any airow through the extractor
hood when not in use.
• A drying cabinet with its own fan can be indirectly
connected to the outlet valve using the connection
system of the drying cabinet.
• A part of the extract air is taken from the living
space and a part from the drying cabinet.
• The extract air must ow through the valve at
a speed of 12 litres / second minimum.
• Install silencers at least in the supply and extract
ducts.
