[. . . ] 3 To avoid a draught in the room, it is advisable to place the air inlet behind the dryer. The area* of the air inlet opening must be 5 times the size of the vent pipe area. The resistance in the grating/slats on the air inlet cover plate should not exceed 10 Pa (0. 1 mbar). *The area of the inlet opening is the area through which the air can flow without resistance from grating/slatted cover. Note that gratings/slatted covers often block half of the total fresh air vent area. Remember to take this into account. 2 A 5xA XXXX X 24 05. 01 487 19 3 5xA 487 14 22 21 - 4250/4350 GB Installation manual Evacuation system for installation of several machines with a shared evacuation pipe Evacuation pipe Fig. 1 It is recommended that each dryer be connected separately to a smooth air outlet pipe with the lowest possible friction. For safety reasons it is important that the dryer is connected to a smooth evacuation pipe with a 200 mm diameter. When installing several machines on shared evacuation pipe, increase the area of the pipe with each additional machine so that each dryer will be working at the same air resistance. Fig 1 and the below table show in simplified form how the evacuation pipe should look. 1 15 2 The outlet The pipe must end outside in the open. In cold areas, condensation may cause frost damage to the building. Installation in frigid laundries In frigid laundries and where the air resistance is very low it can be a problem to reach 12°C within the given time (Error code E18 will be displayed). In this case it will be necessary to throttle the outlet air on the damper in the evacuation pipe. Gentle bends Fig. To keep the air flowing, ensure proper dryer operation, and minimize lint build-up in the exhaust system, never connect ducts at right angles, always use gentle bends. The evacuation pipe diameter must not be reduced. 5 400 6 450 7 475 8 500 9 535 10 560 No. By opening / closing the damper B the static pressure at A is either lowered or raised. 1 120 Table with static pressure The optimum air volume is achieved if the pressure is adjusted according to the table below.

The static pressures in this table are not to be mistaken for the counter-pressure from the pressure drop curve. 487 14 22 21 - 4250/4350 GB Installation manual Steam installation Before start The steam pipe must be cut off and must not be under pressure. 19 Steam Steam 3-10 bar absolute pressure (130180°C). 5 a b Steam forward 1. The branch pipe's branch must be located at the top of the main steam pipe to prevent condensation in the steam. The branch pipe must have a descending gradient and must end at a height above the inlet connecting branch (5). Mount a plug valve (a) and a dirt collector (b) in the branch pipe. O 6 a bc N M Condensation return 1. It is important that the branch pipe for condensed water on return to the main condensate pipe has a descending gradient and is lower than the outlet connecting branch (6). Mount pressure hoses between branch pipes and dryer (hoses are not supplied). 487 14 22 21 - 4250/4350 GB 20 Installation manual 1 Steam-heated dryer Mounting steam calorifier on dryer Dryer type 4250: The steam calorifier is on the pallet. Demount supporting rail on the dryer, see arrow (note which way the supporting rail turns as it has to be remounted the same way, see step 5).
