Feed water connections
The air curtain is equipped with a water supply pipe connection (IN) and a water return pipe
connection (OUT) on the left top of the unit. The sizes for water connection range between
½" and 1½" (inner thread), depending on the heating performance of the unit. A drain valve is
located at the bottom of the heat exchanger and is accessible through the service hatch.
Two shut-off valves should be installed to allow trouble-free dismantling of the air curtain.
An (automatic) aeration valve should be installed at the highest point of the pipe work.
Attention! All installation work must comply with local regulations. All work concerned
!
with the electrical installation of the air curtain MUST only be performed by skilled
and qualified technical personnel.
Outlet temperature control
The outlet temperature of the air curtain can be adjusted to a consist level by using an optional
thermostatic (three way) valve. The valve has to be mounted in the water supply pipe. The sensor
needs to be mounted on the fan at the left hand side by using the pre mounted sensor support.
Use the perforation at the top left side of the unit to lead the sensor inside the unit (remove the
cap). See also the information provided with the thermostatic valve for more details.
Solenoid valve
The air curtain is equipped for the use of an optional solenoid valve 230VAC/50Hz to shut
the water supply off during summer time. The solenoid valve is electrically connected on the
terminal block at the top side of the unit. The terminal block is positioned next to the controller
terminal block, see the wiring diagrams further on this manual for details.
Electrical connections
The standard position of the terminal block to connect the electrical power supply is located
at the right hand top side of the air curtain. Every connection must be made according to the
wiring diagram. Keep in mind that an electrically heated air curtain needs a 3 phase power supply
