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. Allowable water pressure of hydro unit is maximum 3.0 bar. 2 service valves are provided with the Hydro unit.
ENGLISH 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. Before connecting pipes to the hydro unit, Flush water pipes clean to remove contaminants during 1 hours using a flushing unit or tap water pressure if it is adequate (at 2 to 3 bar) 4.
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. Norminal ax . Hydraulic Head Loss(mH2O) To secure enough water flow rate, set water pump speed as “Max.”. The standard pressure drop of the unit is 30~35 kPa.
ENGLISH 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. Expansion Vessel capacity (Liter) 14.00 12.00 10.00 Norminal [Lit] 8.
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. Open the service valve in the water supply connection. Water pressure of supply line shall be over 2.0 bar for good charging work. Stop water supply when the pressure gauge of hydro unit indicates 2.0 bar.
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. Make certain that the discharged water out of drain pan can not contact any electrical parts.
Wiring work Field-supplied electrical components such as power switch, circuit breakers, wires, terminal blocks, etc must be properly chosen with compliance with national legislation or regulation. Switch off the power supply before making any connections. All field wiring and components must be installed by a licensed electrician. Use a dedicated power supply.
