Magna Rail extraction system, designed for use with emergency vehicles, is flexible and easy to use. The system is also suitable for lorries, buses, and other vehicles with exhaust pipes located beneath, at the back or the side of the vehicle. The system is particularly well suited for stations where two vehicles have their own individual parking spaces after each other. However, the system is also well suited for use with only one vehicle. The station can have drive in doors at one side of the building and drive out doors at the opposite side. The system is also possible to use in stations with doors only at one side of the building, where it is necessary to reverse the vehicles into their parking spaces. To guarantee a correct function and a minimal service, it is important to read and understand the information in this instruction manual. The manual contains important warning directions which have to be read and followed. DELIVERY CHECK 1 Magna Rail is delivered in the following units. A. Horizontal exhaust rail B.

ASSEMBLY INSTRUCTION (RAIL, TROLLEY UNITS) Before the exhaust track can be installed, a suitable height must be determined in relation to the vehicle's parking space in the garage. The distance from the floor to the bottom edge of the track should normally be 3-5 m. The track should be installed at least 0.3 m from the side of the garage opening (see figure). If Magna Rail is to be used between two vehicles, the distance between the vehicles must be at least 0,6 m. The distance from the rail's leading edge to the station door should as small as possible, as long the door can open freely without interference to the rail. Because of the module construction and the possibility to choose a 3 m or a 4 m vertical hose, the MagnaTrack can be adjusted to existing station measurements. Cutting the horizontal or vertical hose is therefore not recommended. In exceptional cases, for example at damages, cutting the hoses can be accepted. To avoid incorrect function the vertical hose must only be shortened with help of a Nederman mounting kit. Part no. 371705 Mounting kit for cutting the upper part of upper vertical hose. 371706 Mounting kit for cutting the lower part of upper vertical hose. 0,3-0,5 m min. 0,3 m 3-5 m 1 Ceiling mounting Secure the mounting brackets directly to the ceiling or support beams or similar.

INSTALLATION CHECKLIST When the mechanical assembly, fan connection and electrical installation of MagnaTrack is complete, the system is ready for use after double- checking the following points. Check the disconnection procedure. The extraction hose should disconnect from the exhaust pipe immediately before the station door opening at normal speed, not more than 20 km/h. Adjust the disconnection position by moving the disconnection magnet on the front rail (see assembly instructions, point 11). Check that the hose lifts away correctly after disconnection and that it does not touch the station floor. When required, adjust the balancer lifting power according to the instructions in the maintenance instructions (page 18). Check that the hose does not catch any part of the vehicle or the station door. Check the air flow (800-1200 m 3 /h for 6" nozzle and 400-800 m 3 /h for 5" nozzle at idling speed are normally recommended) in the nozzle opening with an air flow indicator. If required, check the fan impeller rotation direction and/or damper function. Check the electrical installation (connection box, disconnection boxes, breakers, electro magnet) according to the wiring diagram. Make sure the extraction unit no. 1 stops properly in its stop profile. If the disconnection does not work at all in the forward direction, move the contact in the disconnection box according to this figure. Check that the extraction units don t crash into each other after a turn-out. If so, check if the distance between the stop profiles is at least 800 mm. Check that the rail has been braced (see example page 5) so it is stable when it is in operation. Clean the rubber seals internally. Clean the trolley wheel tracks in the rail. AUTOMATIC START/STOP DEVICE FOR FAN As an alternative the fan can be automatically activated by a start/stop device which can be ordered as an option.
