    Alde Compact 3020 HE Operating Instructions 4.1 Filling Figure 2. The central heating system is filled with HTF through the expansion tank, either by hand, or using the Alde service pump. Any containers used for handling or storing the HTF should be checked first, and must be visibly clean to avoid introducing contaminants or foreign objects into the system. Alde recommends using the Alde 1900-811 or 839 twin-motor service pump to fill the system. To fill the system by hand, unscrew the expansion tank cap (Fig 2 [R]), and lift the circulation pump (Fig 2 [S]) out of the tank (if Fluid level applicable). Carefully pour the HTF into the tank, and repeat until the fluid level is about 1 cm above the MIN mark when cold. 4.2 Draining The installer should fit one or more drains in the central heating system to allow draining of the HTF. Because the pipes step up and down, some HTF will be left in the system after draining. TiP! The easy way. Contact an Alde-certified service agent to drain and refill your system.
