Wiring and Commissioning
Using flexible stainless hoses is the easiest way to
connect the water heat exchanger to the heating wa-
ter distribution piping; these hoses can be ordered as
optional accessories (G 3/4"-250 hose; max. operating
pressure 1MPa). Insert a shut-off valve in the air curtain
connecting place to the heating water circuit. The inlet
and outlet line must also be equipped with air-venting
valves to enable exchanger venting. The inlet and outlet
line must be insulated against temperature loss so the
surface temperature will not exceed 60°C.
Due to the product's purpose (installation in normal
environment rooms), antifreeze protection of the water
heater is not considered.
To protect the water heat exchanger during the winter
season, heating circuit pump operation MUST be ensu-
red.
If the water heat exchanger is equipped with a TVW-E
valve cooperating with an associated room thermostat
(RAA10-30), control of the air curtain using a door con-
tact (DK) is not advisable because bringing the heating
up to the required temperature takes more time than the
door opening takes.
Water Heater Connecting Procedure
The installer is responsible for making sure

the connected piping is clean. The water heat
exchanger radiator is not protected against dirt
penetration.
Connect the inlet and outlet lines to the water heat

exchanger headers.
Open the heating water inlet from the heating circuit,

and vent the heating circuit.
Check the connections and heat exchanger radiator

for leaks.
Attention!
The water heat exchangers are not equipped with

air-venting valves. Therefore, the inlet and outlet line
venting must be vented during installation - at the
highest points.
The water heat exchanger connections must cause

no mechanical stress.
When installing the thermo-valves, it is necessary to

observe the heating medium flow direction as
marked at the connection place (counter-current
connection).
The thermostatic valve or solenoid valve installation
is described below.
The D2 air curtain water heater is equipped with four

connecting necks (G 3/4"). Two upper threaded
necks protruding from the air curtain casing (upper
panel) are intended for the heating water circuit
while the other two threaded necks inside the air
curtain are intended for the thermostatic valve
connection, and are closed with brass plugs, refer to
the section "Accessory Installation" on page 14.
Wiring
It is necessary to ensure safety during this activity, i.e.
safely disconnect the product, respectively the power
supply, by switching off the main switch (circuit breaker)
and leaving a warning (a sign with the text: "Do not
switch on. Work is being performed on the device.").
Observe all safety rules included in these Installation
and Operating Instructions as well as other safety rules
for operation and maintenance of this product.
Air curtains are designed to be connected to 230V+-
N+PE /50Hz or 3x400V+N+PE /50Hz power supply
system. The mains must be properly protected, and
safe disconnection must be enabled to ensure the non-
-voltage state. The air curtain's main power supply pro-
tection must be equipped with a switching trigger which
is an integral part of the air curtain's overheating protec-
tion system. Installation and operation of the air curtain
without a lockable main switch enabling safe power
supply disconnection is forbidden. The protection and
main switch dimensioning data are included in table #1.
Place the protection and main switch in a corresponding
switchboard box.
Connect the air curtain using a wiring harness with
conductor cross-section dimensioned according to the
current load. Lead the cable through the cable bushings
situated in the upper air curtain panel, and connect it to
the terminal box inside the air curtain (follow the wiring
diagram). To enable access to the terminal box, it is
necessary to remove the air curtain covers, refer to the
description above. The wiring must comply with the wi-
ring diagram; refer to page 17 and the following pages.
