WARNING
11.3 Piping Installation
This section is for authorized and licensed electrician / water
system installer only. Work behind the front plate secured by
screws must only be carried out under supervision of qualified
contractor, installation engineer or service person.
Please engage a licensed water circuit installer to install this
water circuit.
The minimum requirement of water in the system is 50
litres.If this value could not be achieved, please install
additional buffer tank (field supply).
This water circuit must comply with relevant European
and national regulations (including EN61770), and local
building regulation codes.
Ensure the components installed in the water circuit could
withstand water pressure during operation.
Do not apply excessive force to piping that may damage
the pipes.
Do not install any valve between Monobloc unit and water
piping to avoid accidental closure of water supply to the
Monobloc unit.
Use Rp 1 ¼” nut for both water inlet and water outlet
connection and clean all piping with tap water before
install.
If old heat pump terminal / tank is utilized, please clean
the dust properly before installation.
Refer Diagram 3.1 for installation of 3-way Valve Kit.
In case of a power supply failure or pump operating failure,
drain the system (as suggested in the figure below)
When water is idle inside the system, freezing up is very
likely to happen which could damage the system
Must install an external filter (30 mesh or more, field
supply) before water inlet connector of Monobloc unit
(indicate with “WATER IN”).
Connect the external of Monobloc unit (indicate with
“WATER OUT”) to boiler tank inlet. Fail to connect the
tube appropriately might causing the Monobloc unit
malfunction.
Choose proper sealer which can withstand the pressures
and temperatures of the system.
Make sure to use two spanners to tighten the connection.
Further tighten the nuts with torque wrench in specified
torque as stated in the table.

If non-brass metallic piping is used for installation, make
sure to insulate the piping to prevent galvanic corrosion.
Do not use worn out piping.
Make sure to insulate the water circuit piping (insulator
thickness : 20mm or more) to prevent reduction of heating
capacity, as well as avoid freezing of the outdoor water
circuit piping during winter season.
After installation, check the water leakage condition in
connection area during test run.
Drainage piping installation
Use a drain hose with inner diameter of 15 mm.
The hose must be installed in a continuously downward
direction and left open to the frost-free atmosphere.
If drain hose is long, use a metal support fixture along the
way to eliminate the wavy pattern of drain tube.
The water may drip from this discharge hose. Therefore
must guide the hose without close or block the outlet of
the hose.
Do not insert this hose into sewage hose or cleaning hose
that may generate ammonia gas, sulfuric gas, etc.
If necessary, use a hose clamp to tighten the hose at
drain hose connector to prevent it from leaking.
