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 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.
•
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 condensation during cooling operation and 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.

RECONFIRMATION
WARNING
Be sure to switch off all power supply before performing each of the below checkings. Before
obtaining access to terminals, all supply circuits must be disconnected.
CHECK WATER PRESSURE *(0.1 MPa = 1 bar)
Water pressure should not lower than 0.05 MPa (with inspects the Water Pressure Gauge 4). If
necessary add tap water into the water circuit.
CHECK PRESSURE RELIEF VALVE a
•
Check for correct operation of Pressure Relief Valve a by turning on the lever to become
horizontal.
•
If you do not hear a clacking sound (due to water drainage), contact your local authorized dealer.
•
Push down the lever after fi nish checking.
•
In case the water keeps drained out from the unit, switch off the system, and then contact your
local authorized dealer.
