5. 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 damaging the fan and consequently malfunctioning of the device. The air inlet and outlet must not be blocked by any objects.
While installing 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 GUARD 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 curtains 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.
Connecting GUARDPRO curtains
The GUARDPRO
multi-purpose connector
is designed to connect curtains and to mount curtains to the ceiling (in case of
horizontal mounting) or to the wall (in case of vertical mounting).
The GUARDPRO 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 GUARDPRO multi-purpose connectors may be calculated from the formula below
