MONO BLOC UNIT INSTALLATION
2
Mono bloc unit will become heavy when fi lled with water. Please
install the unit on a strong concrete fl oor and consider the weight of
the unit and water.
•
Fix Mono bloc unit on the concrete fl oor with M12 anchor bolt at
4 locations.
•
Pull-out strength of these anchor bolts must be above 15000N.

PIPING INSTALLATION
3
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 qualifi ed
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 (fi eld 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.
•
Use Rp 1¼" nut for both water inlet and water outlet connection
and clean all piping with tap water before connecting to the Mono
bloc unit.
•
Cover the pipe end to prevent dirt and dust when inserting it
through a wall. If an existing tank is to be connected to this Mono
bloc unit, ensure the pipes are clean before water pipe installation
is carried out.
•
An external fi lter (30 mesh or more fi eld supplied) must be installed
before the water inlet of the Mono bloc unit.
•
Refer to Diagram 3.1 for pipe connection of Radiator, Floor Heater,
Tank Unit, Solar Pump Station, 3-way Valve Kit and etc. Fail to
connect the pipes appropriately might cause the 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. Tighten
the nuts with torque wrench: 117.6 N•m.
•
If non-brass metallic piping is used for installation, make sure to
insulate the piping to prevent galvanic corrosion.
•
Do not use pipes that are crushed or deformed. If these inferior
pipes are used, it may cause unit malfunction.
•
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.
•
In case of a power supply failure or pump operating failure, drain
the system (as suggested in the fi gure below).
When water is idle inside the system, freezing up is very likely to
happen which could damage the system.

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 fi xture along the way to
eliminate the wavy pattern of drain tube.
•
Water will drip from this hose , therefore the outlet of this hose must
be installed in an area where the outlet cannot become blocked.
•
Do not insert this hose into sewage or drain pipe 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.

CONNECT THE CORD AND
4
CABLE TO MONO BLOC UNIT
(REFER TO WIRING DIAGRAM AT UNIT FOR DETAIL)
1. An isolating device must be connected to the power supply cable.
•
Isolating device (Disconnecting means) should have minimum
3.0 mm contact gap.
•
Connect the approved polychloroprene sheathed power supply 1
cord (3 x 4.0 or 6.0 mm
type designation 60245 IEC 57 or heavier cord to the RCCB, and to
the other end of the cord to isolating device (Disconnecting means).
2. To avoid the cable and cord being damaged by sharp edges, the
cable and cord must be passed through a bushing (located at the
right hand side of the mono bloc unit) before being connected to the
terminal block. The bushing must be used and must not be removed.
3. Secure the cable onto the control board with the holder (clamper).
