INSTALLATION
When deciding on the air curtain position you should take into account such factors as:
•
Ease of access for servicing,
•
Access to water and electricity supplies
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 levelled. In case of positioning in a different way than horizontal or vertical, during
installation, damage to the fan may occur and in consequence malfunction of the unit.
Inlets and outlets cannot be blocked by any objects. When installing the curtains, keep in mind that you will have free access to the
control panel. With larger door openings, it is possible to mount more curtains of the same type, one by one, 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).
Curtain connection should be done in a serviceable manner, manual shut-off valves should be installed on both nozzles to enable
disconnection. In case of a solenoid valve (option - automatics), it must be connected at the water outlet of the device, otherwise it
may be damaged. When tightening the pipeline to the exchanger, the heater connection must be protected against torque (which
may cause leakage in the exchanger).
Horizontal installation under the ceiling using mounting pins
Installation under the ceiling is done by using 4 M8 pins. In order 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.
