Do not overtighten, overtightening may cause gas leakage.
2. Please make fl are after inserting fl are nut (located at joint portion of
tube assembly) onto the copper pipe. (In case of using long piping)
3. Do not use pipe wrench to open refrigerant piping. Flare nut may
be broken and cause leakage. Use proper spanner or ring wrench.
4. Connect the piping:
•
Align the centre of piping and suffi ciently tighten the fl are nut
with fi ngers.
•
Further tighten the fl are nut with torque wrench in specifi ed
torque as stated in the table.
CUTTING AND FLARING
THE PIPING
1. Please cut using pipe cutter and then remove the burrs.
2. Remove the burrs by using reamer. If burrs is not removed, gas
leakage may be caused. Turn the piping end down to avoid the
metal powder entering the pipe.
3. Please make fl are after inserting the fl are nut onto the copper pipes.

Water Piping Installation
•
Please engage a licensed water circuit installer to install this
water circuit.
•
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 use worn out tube.
•
Do not apply excessive force to pipes that may damage the pipes.
•
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 specifi ed torque as stated
in the table.
•
Cover the pipe end to prevent dirt and dust when inserting it
through a wall.
•
Choose proper sealer which can withstand the pressures and
temperatures of the system.
•
If non-brass metallic piping is used for installation, make sure to
insulate the pipes to prevent galvanic corrosion.
•
Use correct nut for all Tank Unit tube connections and clean
all tubes with tap water before installation. See Tube Position
Diagram for detail.

Do not overtighten, overtightening may cause water leakage.
•
Make sure to insulate the water circuit pipes to prevent reduction
of heating capacity.
•
After installation, check the water leakage condition in connection
area during test run.
•
Failure to connect the tube appropriately might cause the Tank
Unit malfunction.
•
Protection From Frost:
If the Tank Unit is being exposed to frost while power supply
failure or pump operating failure, drain the system. When water is
idle inside the system, freezing up is very likely to happen which
could damage the system. Make sure the power supply is turned
off before draining. Heater Assembly 8 may be damaged under
dry heating.
•
Corrosion Resistance:
Duplex stainless steel is naturally corrosion resistant to mains
water supply. No specifi c maintenance is required to maintain
this resistance. However, please note that Tank Unit is not
guaranteed for use with a private water supply.
•
It is recommended to use a tray (fi eld supply) to collect water
from the Tank Unit if water leakage occur.

(B) Domestic Hot Water Tank Pipework
•
It's strongly recommended to install an expansion vessel (fi eld
supply) in the Domestic Hot Water Tank circuit. Refer Typical Piping
Installation section to locate the expansion vessel.
  Recommended pre-charge pressure of the expansion vessel
(fi eld supply) = 0.35MPa (3.5 bars)
•
In high water pressure or water supply is above 500kPa, please
install the Pressure Reducing Valve for water supply. If the pressure
higher than that, it might damage the Tank Unit.
•
A Pressure Reducing Valve (fi eld supply) with below specifi cation is
strongly advised to be installed along the line of the tube connector
i of Tank Unit. Refer Typical Piping Installation section to locate
both of these valves.
Recommended Pressure Reducing Valve specifi cations:
- Set pressure: 0.35 MPa (3.5 bars)
•
Must connect a faucet to Tank Unit Tube Connector j and main
water supply, in order to supply water with appropriate temperature
for shower or tap usage. Failure to do so might cause scalding.
•
Failure to connect the tube appropriately might causing the Tank
Unit malfunction.
(C) Pressure Relief Valve Drainage Pipework
•
Connect a drain hose to the Pressure Relief Valve hose outlet
•
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 fi xture 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.
