Operation and Maintenance Documentation

ASSEMBLY
Before mounting the unit, take into consideration the followings:
• accessibility/easy access for any servicing and maintenance works
•
access to water and electrical installation
•
possibility to mount the curtain directly at the gate entrance
It is advisable to mount the device to the wall or the ceiling above the doorway on supporting mount pins or supporting
constructions ( shapes and dimensions of the supporting construction may be individually designed in compliance with durability
and strength requirements).
Pay special attention to proper leveling of the device. If the device is not placed in a horizontal or vertical position, it may result in dam-
aging the fan and consequently malfunctioning of the device. The air inlet and outlet must not be blocked by any objects. While install-
ing the unit, remember to provide easy access to the control panel. A few curtains of the same type may be installed in case of a bigger
doorway. They must be assembled side-by-side to make an uninterrupted stream of air. The curtain is mounted horizontally or vertically
for permanent (on the left/right side of the doorway). The
ACR Pro
air curtain is advised to be wider (in case of horizontal mounting) or
higher (in case of vertical mounting) than the gate way. If you decide on ACTIVE PROTECTION system, which is the assembly of cur-
tains with water exchanger and without one, you have to mount air curtains with water exchangers on the bottom.
When connecting the curtain, make sure that maintenance work is possible to be conducted. On both connection nozzles manual shut-
off valves should be installed in case of the necessity of disconnecting the unit. The hot water medium supply must be connected in
accordance with the marking on the casing (inlet/outlet). When pipes being screwed to the heat exchanger make sure you secure the
inlet connection of the heater to protect it against the torque (that may cause leakage in the heat exchanger).
The connections of heating medium with the threaded nozzles DIN 3/4” should be based on the project carried out by an
authorized designer. In case of connecting the curtain to the heating network with no mixing module, a water filter must be
installed.
NOTICE !
Pay special attention to proper leveling of the device. If the device is not placed horizontally or ver
-
tically, it may result in damaging the fan and consequently the malfunction of the device.
To sustain proper functioning of the device, keep safe distances as given in Figure below.
Connecting
ACR Pro
curtains
The
ACR Pro
multi-purpose connector is designed to connect curtains and to mount curtains to the ceiling (in case of horizontal mount-
ing) or to the wall (in case of vertical mounting). The
ACR Pro
multi-purpose connector is not included in the content of the delivery and
is available optionally. The connector should be installed in accordance with the figures below. The required number of the
ACR Pro
multi-purpose connectors may be calculated from the formula below
Horizontal assembly (N – number of curtains)
N x 4 = number of ACR Pro multi-purpose connectors
Vertical assembly (N - number of curtains)
(N x 4) – 2 = number of ACR Pro multi-purpose connectors
Installation of connector inside the curtain
Installation of connector at the back of the
curtains
