Installation 18 Installation on board a ship The four accompanying fittings are fastened to the foundation by means of 4 x M10 set screws.
Installation Evacuation system 19 7 Air principle 7 The ventilator creates low pressure in the dryer, drawing air into the drum via the heating unit. The heated air passes through the garments and the drum vents. Then the air flows out through a lint filter positioned immediately in front of the ventilator. After this, the air is evacuated through the ventilator and evacuation system. It is very important that the dryer gets enough fresh air, see next section.
Installation 20 Exhaust duct • The exhaust duct must be smooth on the inside (low air resistance). • The exhaust duct must lead to the outdoors. • The exhaust duct must lead clear of the building as condensation may cause frost damage to the building. • The exhaust duct must be protected against rain and foreign objects. 10 • The exhaust duct must have gentle bends. • The exhaust duct must not be a shared duct between dryers and appliances using gas or other fuels as their energy source.
Installation 21 Gentle bends 10 W00049 Several dryers share an exhaust duct 11 W00052
Installation 22 Outlet dimensioning It is important that the dryer has the correct air volume compared to each dryer’s effect. If the air volume is smaller or larger this will result in a longer drying period. Table with air volume and dryer effect Minimum air volume If the outlet air volume gets below the minimum air volume the microprocessor will report an error and error code E15 will be displayed. Type Effect Minimum Optimum kW air volume m3/h air volume m3/h 4250 6/9 260 360 4250 13.

Installation 24 Adjusting the dryer The dryer is adjusted by dismounting the back plate and measuring the static pressure behind the fan. 13 13 Drill a ø3.3mm hole A if there is not already one. The measuring is done on a no-heat program, without clothes in the dryer and with the back plate being dismounted. 120 By opening / closing the damper B the static pressure at A is either lowered or raised.
Installation Steam installation 25 14 Before start The steam pipe must be cut off and must not be under pressure. Steam a b 5 Steam 3-10 bar absolute pressure (130- 180°C). Steam forward 14 1. The branch pipe’s branch must be located at the top of the main steam pipe to prevent condensation in the steam. 2. The branch pipe must have a descending gradient and must end at a height above the inlet connecting branch (5). For measurements M, N and O, please see dimension sketch page 7. 3.
Installation 26 Steam-heated dryer 15 Mounting steam calorifier on dryer Dryer type 4250: The steam calorifier is on the pallet. Dryer type 4350: The steam calorifier is in the drum. 1. Unpack the calorifier. 15 2. Demount top back plate on the dryer. 3. 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). 4. Hang the calorifier on the bottom supporting rail on the dryer. 5.
Installation Leak test 1. Leak test the system. 2. Clean the dirt collectors (b), see the previous page. Function check The function check is described in the back of this manual. Pipe insulation All pipes must be insulated in order to reduce risk of burning. Insulation also reduces loss of heat to the surroundings.
Installation Gas installation To be carried out by qualified personnel Mount a shut-off valve upstream from the dryer. The gas connection to the dryer should be dimensioned to an output of 13.5 kW / 21 kW dependent upon the kW-rating of the dryer. The factory nozzle pressure setting corresponds to the fuel value given on the name plate. Check that the nozzle pressure and fuel value agree with the values given in the table. If not, contact the supplier. Bleed the pipe system before connecting the dryer.
Installation 30 Converting instructions to another gas type Before installing the dryer affix the label "Read the user instructions" to the inside of the door, see pictures below. The label must have the correct country code - choose the correct label from the kit. 80 mm GB, IE NL Read the technical instructions before installing the appliance. Lees de technishe instructies zorgvuldig door voordat u het apparaat installeert.
Installation 31 Table of pressure and adjustment This gas appliance has been build to run on natural gas group I2H and I2E(LL), commonly identified by GNH.
