Charging Water - Samsung RC***MHXGA Installation Manual

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 Air-Water Heat Pump.
 Air vent valve shall be open at least 2turns so that air can be
eliminated in the system.
 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 around 2.0 bar.
• There shall be enough space for Service works.
• Water pipe and connections shall be cleaned by using water or cleaner before operating the unit at first time.
• Considering E.S.P and water pump performance, select water plumbing specification and under floor loofs.
• Make sure to calculate the total resistance of piping system and determine the size of pipes before selecting the
required head of pumps. If the pressure loss of total water system is over than designed pressure, an external water
pump shall be installed on piping system in series.
• Do not connect power supply while water is charging.
• When initial installation or re-installation is required, remove air by air vent valve in water plumbings which are
installed by local installers to prevent air trap in the system while charging water.
• Make sure that back flow preventer (check valves) shall be installed on main supply line to prevent from
contaminating the city water.
- It is recommended to install the make-up water assembly to prevent from contaminating the city water.
- Check valves in the make-up water assembly can prevent running water inside hydro unit from contaminating
water supplies during installation or maintenance works.
