Installation | Installation Installation site Floors, foundations, ceilings or steel construction must be checked as to the planeness. Unplaneness causes a more dif- ficult mounting and the canting of the doors. The consequences among other things are doors which can heavily be opened and which are untight.
| Installation Note: The necessary screws and sealings for the mounting are attached loose to each delivery and deposited in the ventilator part. screws type term M8 x 20 mm Galvanized sheet, thickness: 2–3 mm U-70 M8 x 20 mm U-structural steel, rounded U-structural steel, rounded U-100 und U-120...

Please vacuum these chippings immediately from the housing parts since rust spots can ensue. Mounting indications for the kind of delivery: „dismantled assembly group“ •...
| Internal components Mounting indications for wet parts Cooler parts have to be mounted and filled very Detail A: tub protruding at the bottom thoroughly Detail B: tub flush at the bottom Internal components V-cell-filter Due to its large filter surface has a high air throughput. The pollution must be controlled with a differential pressure device (U-tube, inclined tube).
Internal components | Air heater, air cooler and glycol-compound system After the mounting of the heat exchanger units the ribbed surfaces must be covered to avoid mechanical damages. The connection of the heat exchanger, air heaters as well as the coolers must be made de-energized. When exchanging the filter, pollutions must be removed.
| Internal components Electrical heater The casing is made of Aluzinc-coated sheet steel, AZ 185, that conforms to the requirements for corrosivity class C4. The heater elements are made of stainless steel to EN 1.4301. The junction box includes the terminal blocks necessary for the electrical connections.
Internal components | Jalousie damper Jalousie flaps are equipped with polyamid-bearing- sleeves. These need not be maintained (do not put oil or grease on them). Please pay attention that the jalousie flaps must be opened before switching on the ventilator and that the ventilator must be switched off before the closing of the jalousie flaps.

| Outdoor installation Negative pressure Overpressure Outdoor installation Important ♦ If the weather protection roof cannot be bought immediately, the top of the unit must be covered watertight. ♦ The outside joints of outdoor units have to be permanently elastic sealed. While assembly work the joints must be proved.
| Condensation and heat insulation Top view Important It should be ensured that the base frame is insulated. Without insulation it can occur condensat. Condensation and heat insulation Outdoor air duct and exhaust ducts must always be well insulated against condensation. Correct insulation installation on ducts connected to the unit is especially important.
