To ensure the optimal performance of this low-tech system this manual offers advice on the position- ing of the various components of the SV30AWX. It will also deal with the initial adjustment, the op- eration and maintenance, and it will give you additional technical information concerning specific components in the system. -
Page 4: The Sv30Awx Principle
Hot water out The most important components of the SV30AWX are: SV30AWX solar collector with solar cells and fan - expansion tank - cylinder - pump The SV30AWX produces:- Fresh and warm air, which keeps your house pleasantly dry and moderately heated most •... -
Page 5: An Sv30Awx Solar Collector On The Roof
1.2 A roof mounted SV30AWX solar collector Please note that the SV30AWX solar collector is located with the long dimension parallel to the horizontal - or the side with the solar cell at the highest position. Inlet and outlet are always placed on the same side of the collector. By rotating the collector 180º... -

Please read separate instructions for further details. 2.2 How to position the hot water cylinder The hot water cylinder should be installed so that the horizontal distance to the SV30AWX solar collector is as short as possible. The hot water cylinder can often be located in a scullery or a furnace room or wherever practical. However, there must be access to both power and the domestic water supply. -
Page 7: Concerning Piping Location
2.3 Concerning piping location Horizontal or ascending piping from the hot water cylinder to the SV30AWX solar collector is optimal. Otherwise you may have problems starting the installation. It is possible to place the expansion tank below collector level. However, the difference in height between the top of the collector and the bottom of the expansion tank should be a maximum of 2 m. -

3.1.1 Drilling holes in the roof One hole Ø = 20 mm is made for the cold piping to the SV30AWX solar collector. This hole is made next to the lowest pipe outlet on the collector. (For type 1, take care always to drill in crests!) A second hole Ø... -

3.4 Installing the expansion tank Hot fluid from the solar collector Air inlet and outleton top of expansion tank extra fluid may be filled in here Expansion Tank Clear tube to control fluid level. Hide under the collector when not in use. Put a lid on top of this tube (with a tiny hole for the air) The expansion unit has several purposes: to absorb the expansion of the fluid when hot... -

3.5 Installing the hot water cylinder Important: The base or wall fittings must be dimensioned to carry a full cylinder (app 150 kg) 3.5.1 Fittings on the hot water cylinder The hot water cylinder is supplied with a range of connecting parts and a pump. Please follow the direc tions for fitting these items. -

4.0 The SV30AWX in operation Now it is time to connect the hot water cylinder to the SV30AWX solar collector and the expansion tank. There are some important steps to follow. First of all a specific quantity of water must be supplied. -
Page 13: Starting Up A New Installation
4.4 Re-starting your SV30AWX If you have turned off the fluid based part of your SV30AWX for a period, it is necessary to re-start it. Whilst the equipment is already filled with liquid, this will normally cause no problem. -
Page 14: Venting The Installation
5.0 Venting the equipment Switch off the pump (disconnect on separate switch or draw out a wire) The pipe union on the pump case should be turned counter-clockwise until air emerges. When the liquid starts flowing shut it again. Switch on the pump and add liquid, if needed. Note: It is not recommended that you switch off the pump when leaving the house, except for periods when only warm air input is needed. -
Page 15: Performance
7.0 Performance The installation has now been adjusted and is ready to perform. The SV30AWX solar collector will heat the domestic water totally or partly. The separate electrical water heater will provide any after-heating necessary when the solar collector does not produce enough.
