Ducting
Air to and from the unit is led through a duct system. To ensure long life and satisfactory cleaning
possibilities, ducts made of galvanized steel are highly recommended.
To obtain high efficiency, low energy consumption and the required airflow, the duct system should be
commissioned for low air speeds and low pressure drops.
NOTE!
Do not connect tumble dryers to the ventilation system
Duct connections/duct ends should be covered during storage and installation
Grilles for discharge/roof units must be installed according to building regulations in force.
Duct connections
To ensure air tightness the connections needs sealing strips or sealing compound between the ducts and
the unit.
Attention
To avoid fan noise being transferred via the ducting system, silencers should be installed both on supply
and extract air.
Condensation/heat insulation.
All the air ducts must be well insulated against condensation. To obtain the heat recovery efficiency it is
especially important to insulate the Supply and Extract air ducts against heat losses. Use insulating
covering (minimum 100 mm mineral wool) with plastic diffusion barrier.
In areas with extremely low outdoor temperatures during the winter, additional insulation must be installed.
Total insulation thickness must be at least 150 mm.
NOTE! If the unit is installed in a cold place make sure that all joints are well taped and covered
with insulation.
Electrical connection
The unit must not be put into operation before all the electrical safety precautions have been read and
understood.
Electrical connections must be made by authorized installer and in accordance with current
wiring regulations.
See
fig. 2
where to find the electrical connection box.
The TOPVEX unit should be permanently connected to the
mains electric supply through a lockable safety switch, as shown in fig. 7.
The safety switch is not mounted from the factory but delivered with the
unit.
If the unit is equipped with a heater, which has separate power supply
(see table below). The unit shall bee provided with a working switch,
see fig. 8.
N.B
this switch is not included.
