CAUTION
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

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.
(A) Space Heating/Cooling Pipework
•
Connect Tank Unit Tube Connector
g
to outlet connector of Panel/
Floor heater.
•
Connect Tank Unit Tube Connector h to inlet connector of Panel/
Floor heater.
•
Failure to connect the tube appropriately might cause the Tank
Unit malfunction.

(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.
  Expansion Vessel type and specifi cations:
- Size : Not more than
3 /
4
"
- Pre-charge pressure : 0.35MPa (3.5 bars)
•
If secondary return circuits are used then an additional expansion
vessel may be required.
•
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) and Pressure Relief Valve
(fi eld supply) with below specifi cation must be installed along the
line of the tube connector
i of Tank Unit. Refer Typical Piping
Installation section to locate both of these valves.
  Pressure Reducing Valve type and specifi cations:
-
Size : Not more than
3
/
4
"
-
Set Pressure : 0.35MPa (3.5 bars)
 
Pressure Relief Valve type and specifi cations:
-
Size : Not more than 3 /
4
"
-
Set Pressure : 0.8MPa (8.0 bars)
•
The pressure after pressure reducing valve is less than 0.35MPa
(3.5 bars).
•
Must connect a faucet to Tank Unit Tube Connector
j
and urban
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
h
.
•
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.
•
Do not insert this hose into sewage
hose or cleaning hose that may
generate ammonia gas, sulphuric
gas etc.
•
If necessary, use a hose clamp
to tighten the hose at drain hose
connector to prevent it from leaking.
•
Guide the drain hose to outdoor as
illustrated at the right fi gure.
(D) Domestic Hot Water Tank Discharge Pipework
•
Use R½" male connector for Domestic Hot Water Tank Discharge
(Drain Tap)
g
connection.
•
Piping must to be installed in a continuously downward direction
and in a frost-free environment.
•
Discharge pipes must be visible and away from electrical
components.
•
Guide the drain hose to outdoor as illustrated at the right fi gure.
•
It is recommended to fi t a tundish into this
g
pipework. Tundish
should be visible and positioned away from frost environment and
electrical components.
(E) Drain Elbow and Hose Installation
•
Fix the Drain Elbow 3 and Packing 4 to the bottom of Drain
Water Hole
i
.
•
Use inner diameter 17 mm drain hose in the market.
•
This hose must to be installed in a continuously downward
direction and in a frost-free environment. Improper drain piping
may cause water leakage hence damage the furnitures.
•
Guides this hose outlet to outdoor only.
•
Do not insert this hose into sewage or drain pipe that may
generate ammonia gas, sulphuric gas, etc.
•
If necessary, use hose clamp to further tighten the hose at drain
hose connector to prevent leakage.
•
Water will drip from this hose, therefore the outlet of this hose must
be installed in an area where the outlet cannot become blocked.

(F) Temperature and Pressure Relief Valve
j
The Temperature and Pressure Relief Valve
j
need appropriate
discharge pipework. In accordance with Building Regulations a tundish
must be fi tted into the pipework within 600mm of the safety device. Due
to the distance between the two safety devices it may be necessary
to fi t each safety device with its own tundish before run the pipework
together to a safety discharge. The Right Plate
g
has a window so
that the connection can be made to the factory fi tted Temperature and
Pressure Relief Valve
j
. For access, fi rst remove the 4 screws on
the Access Plate
k
. Then connect the Temperature and Pressure
Relief Valve
j
to the discharge pipework (

15mm). Finally, reinstall
the Access Plate
k
. Always replace the plate so that no gaps exist
between the plate and Right Plate
g
to avoid heat loss. The following
instructions are a requirement of UK Building Regulations and must
be adhere to. For the other countries please refer to local legislation.
If there is any doubt the insulation procedure, always contact local
building offi ce.
