OPERATION
WARNING
1. The device must be periodically checked. These activities should be performed ONLY by qualified personnel. If
the device malfunctions, turn it OFF immediately and contact FLOWAIR SERVICE SUPPORT.
2. Do not attempt to repair, move, modify, or reinstall the device yourself. Performing these activities by
unauthorized personnel may result in electric shock or fire.
3. Do not use a damaged device. The manufacturer is not responsible for damages resulting from the use of a
damaged device.
4. The device is intended for indoor use at temperatures above 0°C. At temperatures below 0
°
C there is a risk of
freezing of the medium.
The manufacturer is not responsible for damage to the heat exchanger resulting from the freezing of the
medium in the exchanger.
ADVICE
1. The heating elements are equipped with thermal protections, which in case of too high temperature in their
surroundings will disconnect the heating. The heating can be switched on again after the temperature has
dropped and manual reset is performed by switching OFF and ON the heating with external controller.
If the heating disconnects repeatedly, contact a qualified service center.
2. In the case of water supplied air curtains, when the water from the device is drained for a longer period of
time, the exchanger tubes should be blown with compressed air.

CLEANING AND MAINTENANCE
ADVICE
Periodically check (at least twice a year) the dirtiness level of the heat exchanger (ELIS G W), electric heaters
(ELIS G E). Clogging a part of the air intake causes a decrease in the heating power of the device and adversely
affects the operation of the fan, and in the case of electric heaters it can cause permanent loss of rated
parameters.
Cleaning the exchanger should be carried out in accordance with the following guidelines:
The power supply must be disconnected during cleaning.
Dismantle the fans and clean the exchanger through the air nozzles.
When cleaning the exchanger, be careful not to bend the aluminum fins.
It is not recommended to use sharp objects for cleaning, due to the possibility of damage to the lamellas.
Cleaning with compressed air is recommended.
The exchanger cannot be cleaned with water!
Cleaning should be carried out along the slats, with the blowing nozzle perpendicular to exchanger.
