10 ANTIFROST
To prevent heat exchanger freezing, in winter, the
ventilation unit has an automatic flow unbalancing system.
Temperature sensors measure the air temperature before
entering the heat exchanger and, if necessary, the air
flow coming from outside is temporarily reduced. The flow
unbalance activates with downstream temperature <=
3°C and the fresh air flow rate is decreased proportionally
to reach a safe temperature at the way out the heat
exchanger side exhaust air. The maximum flow unbalance
permitted is 75%
11 CONDENSATE DRAIN
It is important that the air handling unit is installed
horizontally. The condensate drain must be connected to a
site drain / siphon with water trap or an on-site condensate
pump. During operation there may be a negative pressure
up to 500 Pa (equivalent to a 50mm water column) enter
in the flow. In this case, the difference in height must be
50mm minimum in the siphon. Please follow the indication
on illustration to choose the right height in the siphon. The
condensate drain must be airtight from the unit.

SG MANUAL - Heat Recovery unit
Installation - Operation - Maintenance
The unit is equipped with a water pump (internal). The
manufacturer can not be held responsible for any damage
occurring due to non-compliance with the provisions. The
siphon must be installed at the exit of the pipe from the
unit. A constant slope of at least 1cm / m, frost-free must
be ensured up to the final discharge, to protect against
freezing until the end of the air is over. The installer is
responsible for ensuring that the condensate drain is free
from frost.
Important! Check one day before winter start-up, whether
water is in the condensate hose.
