D2 Air Curtain Chaining
Mechanical Connection
The air curtains can be connected to create a visually
non-disturbing assembly. Connection can be carried out
using a connection kit (DM SS CD2 accessory).
Suspension Procedure:
Remove the laminated side walls (5x self-tapping

screw) from the air curtain body at the side of the air cu-
rtain connection.
Suspend the air curtains separately following the

procedure on page 5.
Open the inlet and lower service panels following the

procedure on page 10.
Using the connection holes (see figure below), co-

nnect the adjacent air curtains - connecting kit DM SS
D2.
Remove the electrical equipment side safety guards

and mount the grommet (PG 21) into the D29 hole, see
figure #33
Perform electrical connection of the air curtains. The

wiring can be made inside the air curtain body. Use the
pre-installed grommet to interconnect the air curtains.
Fix the cables to the lower part of the exchanger.
n Properly reinstall all removed parts. Be sure to rein-
stall the ground wire (service panel).

Wiring
a) Fan and Electric Heater Control
Electrical chaining of these air curtains is not limited,
and there is no need for any specific external accesso-
ries. Simple air curtain chaining can be ensured by a
suitable combination of air curtains types.
2 air curtain versions are distinguished by design, de-
signation and code:
A basic air curtain (a standard version for individual

installation); it can only be installed as the last air cur-
tain within the chained assembly.
An air curtain enabling connection of the subsequent

chained air curtain control (the first up to the last but
one air curtain in the air curtain chain) - "M" at the end
of its type designation.
This version enables direct connection of the subse-
quent air curtain's electric heater control to the installed
terminals (XS) allowing the switching of chained electric
heaters as well as fan speed control.
b) Air Curtains with a Water Heater and Thermoelectric
Control using a Room Thermostat
Standard air curtain versions and control accessories
can be used to control the water heaters of chained air
curtains. The thermostat can control as many valves as
is allowed by its electric output dimensioning, otherwise
an external switching element (relay) must be used.
The valve actuators are switched in parallel. Instead
of individual valves and actuators for each exchanger
(air curtain), it is possible to design a valve for common
water supply to multiple air curtains (the valve must be
properly dimensioned in accordance with the required
discharge and it must be equipped with the correspon-
ding actuator).
The electrical interconnection of the chained air curtains
is shown in the wiring diagrams on page 20.
Operating Instructions
Observe all instructions included in these Installation
and Operating Instructions as well as all safety rules for
operation and maintenance of this product.
Unqualified personnel are prohibited to access internal
parts of the device. Each access point to the electrical
equipment is protected by a cover (IP 20) which can
only be removed using tools. It is forbidden to start and
operate the fans if the panels are open or removed, or
without fixed protecting guard covers. All the covers
must be properly secured during operation.
The air curtain connection must be made so that star-
ting up and operation of the air curtain will only be po-
ssible if the main switch is turned on.
Air curtains can be operated automatically (using a door
contact) or manually (using a controller), refer to page
16.
If the main circuit breaker is tripped, e.g. due to short
circuit or thermal protection (emergency thermostats)
intervention, it is necessary to ensure inspection of the
air curtain and removal of the failure by an expert. Only
then can the air curtain be restarted.
