5. INSTALLATION
When deciding on here to position the air curtain attention should be paid to:
E
ase of access for servicing
Access to water and electricity connections
It is recommended to install the air curtain in position above the entrance opening, on the wall or under the ceiling, on support
pins or horizontal mounting brackets. It is also possible to mount it vertically to a wall or other structure using vertical mounting
brackets. It’s important to make sure that the unit is properly
level. If the air curtain is not level, either horizontal or vertical, damage
to the fan may occur causing a malfunction.
Inlets and outlets cannot be blocked by any objects. When installing the curtains,
ensure that access is clear to the control panel.
With larger
door openings, it is possible to mount more curtains of the same type,
one above the other
, to
create an
uninterrupted air flow. The curtain is permanently mounted in either a horizontal or vertical position (on the left/right side of
the entrance).
Connections to the air curtain should be accessible for servicing with manual shut-off valves on both the water connections for
complete isolation of the unit. If a solenoid valve is fitted (option - automatics), it must be connected to the water outlet of the device
or it may get damaged. When tightening the pie connections to the heat exchanger the connection care must be taken not to over
tighten otherwise damage may occur to the heat exchanger.
Horizontal installation under the ceiling using mounting pins
Installation under the ceiling is done by using 4 M8 pins.
To
hang the device on the pins, drill holes Ø 8-9mm in the EPP housing
directly in front of the existing holes in the steel inlet grille. The exact location is indicated by special tags on the EPP
housing. The pins should be screwed into the nippers at a depth of 10-14mm.
