PIPING CONNECTIONS
• All piping that connects to the water supply must be carried out by a licensed plumber.
• The water supplied to the system must comply with the drinking water quality standard.
Use of water that does not comply with this standard could result in a malfunction of the
system.
• The water source must have a min pressure of 200 kPa
• A tundish must be installed under the drain outlet.
• This product cannot be connected to a solar water heater.
• The piping must be insulated using insulation with a thermal conductivity no greater than
0.035 W/m • K and minimum thickness of 15 mm.
• If the piping needs brazing, make sure that all flux and flux splatter is wiped away with a
wet cloth.
• As the hot water supply pipe will expand and contract, use sleeves when passing it
through concrete walls or slabs.
• With buried piping, a sheath pipe will need to be used that has had both ends sealed to
avoid any rain penetration.
• Use only heat-resistant or corrosion resistant material to seal the pipe joints.
• Cutting and wrenching the piping material may result in oil and dust adhering to it. After
fitting, clean the material with a mild detergent before doing any piping work and smooth
the edges to remove any scratches and burrs. (After passing water through the system,
verify whether any dust has accumulated on the filter of the taps and heat pump unit
pipe.)
• When using sealing tape, ensure that no tape is sticking out of the thread.
• If any heat-resistant vinyl chloride pipes (such as HT pipe) are bonded together, pass
water through them after the pipes have set to prevent any bond adhering to the filter or
other parts.
