Page 16 Pipe work (Continued) Water pipe work The hydro unit is equipped with components listed on the table below. The hot and cold water supply connections are clearly marked on the unit with labels. And service valves are provided. Whole water plumbing system including Hydro unit shall be installed by a qualified technician and must comply with all relevant European and national regulations.
Page 17 Flushing and air-purging When filling water, the following start-up procedure should be followed. 1. All system components and pipes must be tested for the presence of leaks. 2. Preparation of a make-up water assembly or Flushing unit is recommended for installation and service. 3.
Page 18 Pipe work (Continued) The water volume and expansion vessel pressure The unit is equipped with an expansion vessel of 8 litres which has a default pre-pressure of 1 bar. To ensure correct operation of the unit, the pre-pressure of the expansion vessel might need to be adjusted and the minimum and maximum water volume must be checked.
Page 19 Setting the pre-pressure of the expansion vessel When it is required to change the default pre-pressure of the expansion vessel(1 bar), keep in mind the following guidelines:  Use only dry nitrogen to set the expansion vessel pre-pressure.  Inappropriate setting of the expansion vessel pre-pressure will lead to malfunction of the system. Therefore, the pre-pressure should only be adjusted by a licensed installer.
Page 20 Pipe work (Continued) Charging water After installation is completed the following procedures shall be used to charge water into the hydro unit.  Connect water lines to water connections of hydro unit.  The air-vent valve shall be opened at least 2 turns and drain valves shall be closed.
Page 21 Pressure relief valve A pressure relief valve is integrated on heater vessel of hydro unit and shall work in abnormal condition for protecting the hydro unit.  The pressure relief valve will operate releasing the pressure by flowing out some water through the drain hose.
