INSTALLATION OF THE EDX-SYSTEM
The ventilation unit is installed according to the separate manual delivered with it. NOTE! LTR-6 and LTR-7 units have to be
installed with the service hatch on the side if they are equipped with EDX. If the supply air coil isn’t built-in, it is to be instal-
led in the duct. Note point 3 here under. Because the EDX system is a cooling system, it has to be drained through a water
lock. The drainage is situatied on the duct coil or in the bottom of the ventilation unit.
Phases of installation:
1. Install the ventialtion unit as advised in the separate manual delivered with the unit. NOTE! LTR-6 and LTR-7 units
have to be installed with the service hatch on the side if they are equipped with EDX. Take into consideration
the space needed for draining the condense water.
2. Make sure that there is enough free space in front of the unit’s maintenance hatch and remember to leave the
electric wirings easily accessible.
3. If the supply air coil isn’t built in, it needs to be connected to the duct. NOTE! The coil should be installed with
the condense drain downwards in a horizontal part of the duct. Attach the duct to the unit with exible connec-
tions. We recommend silencers in the supply and exhaust air ducts. The silencer should be installed after the
supply air coil.
4. Connect a pipe between the drain outlet and the nearest oor drain or water trap of a sink (min. water column
60 mm). Connecting the unit directly into the sewage system is not allowed.
Installation of the outside unit:
The outside unit is installed outside on a max. distance of 20 m and on a max height dierence of 10 m from the coil. There
are no special requirements regarding the placement of the outside unit because the outside air temperature doesn’t
vary much depending on the place of installation. The outside air unit should be mounted steadily to avoid resonance. If
the outside air unit i.e. is mounted on a boarded wall it should be equipped with proper absorbing rubber pads to avoid
resonance. The unit should not be mounted on the wall outside the bedroom, because it is hard to get rid of all resonance.
We recommend that a rack be built for the unit so it doesn’t have to lie close to the wall. It is also possible to build an open
cover for the unit as long as it doesn’t disturb the air ow. The unit is not to be mounted in a closed space.The unit must be
mounted high enough to prevent snow from blocking the air ow in wintertime.
Piping and electrical wiring:
Greenair eco EDX is a combination of a ventilation unit and a heat pump. The heat pump is a cooling apparatus. The instal-
lation of a cooling apparatus requires a license. Installation of cooling apparatus should only be carried out by licensed
companies. The pipes between the outside air unit and the supply air coil are not included in the standard delivery.
The outside air unit also requires electrication. We recommend that the heat pump have its own output on the switch-
board. We recommend that the heat pump be connected to a ground fault circuit interrupter, because it is installed out-
side. Ground fault circuit interrupters are mandatory in new buildings in Finland. Electrical installations as the installation
of cooling apparatus, requires a license. Some companies employ both electricians and installers of cooling apparatus. The
cable between the outside unit and ventilation unit is not included in the delivery.
