connections
1 Water inlet (space heating)
2 Water outlet (space heating)
Field supplied 3 Shut-off valve (field supplied)
Accessories 4 Water check valve
Field supplied 5 Shut-off valve
The following hydraulic elements are necessary to correctly
perform the space heating water circuit:
• Two shut-off valves (field supplied accessory) (3) must be
installed in the unit. One at the water inlet connection (1) and
the other at the water outlet connection (2) in order to make
easier any maintenance work.
• A water check valve (5) with 1 shut-off valve (field supplied)
(4) must be connected to the water filling point when filling
the unit. The check valve acts as a safety device to protect
the installation against back pressure, back flow and back
syphon of non-potable water into drinking water supply net.

Enviroair is not factory-supplied ready for DHW operation, but it
can be used for the production of DHW if the following elements
are installed:
• A domestic hot water tank (8) has to be installed in
combination with the unit.
• A 3-way valve (9) must be connected at one point of the
water outlet pipe of the installation.
• A T-branch (field supplied) (10) must be connected at one
point of the water inlet pipe of the installation.
• Two water pipes (field supplied) (11). One pipe between 3-way
valve and the heating coil inlet (3) of the DHW tank, the other
one between the T-branch and the heating coil outlet (4) of
the DHW tank.
