TEST RUN
1. Before test run, make sure below items have been checked:-
a) Pipework are properly done.
b) Electric cable connecting work are properly done.
c) Mono bloc unit is fi lled up with water and trapped air is released.
2. Antifreeze agent must be added into water circuit to prevent freezing of water when outdoor ambient temperatures is low. Recommended antifreeze:
Propylene glycol: 40% (equivalent to -20°C)
3. Set ON to the Mono bloc unit and RCCB
2
. Then, for remote control operation please refers to (Mono bloc) Air-to-Water Heatpump’s operation instruction.
Note:
•
During winter, turn on the power supply and standby the unit for at least 15 minutes before test run.
Allow suffi cient time to warm up refrigerant and prevent wrong error code judgement.
4. For normal operation, Water Pressure Gauge
4
reading should be in between 0.05 MPa and 0.3 MPa.
5. After test run, please clean the Magnetic Water Filter Set
c
. Reinstall it after fi nish cleaning.
CHECK WATER FLOW OF WATER CIRCUIT
Confi rm the maximum water fl ow during main pump operation not less than 15 l/min.
*Water fl ow can be check through service setup (Pump Max Speed)
[Heating operation at low water temperature with lower water fl ow may trigger “H75” during defrost process.]
RESET OVERLOAD PROTECTOR

Typical 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 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).
H
< H
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.
CAUTION
Do not over tighten, over tightening cause water leakage.

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

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.

PRE PRESSURE CHECKING
[Upper limit water volume of the system]
The Mono bloc unit has a build-in Expansion Vessel with 10 L air capacity and initial
pressure of 1 bar.
•
Without antifreeze agent condition
Total amount of water in the system should be below 200 L.
If the total amount of water is more than 200 L, please add expansion vessel (fi eld supply).
•
With antifreeze agent condition
In the case of using antifreeze agent, expansion rate
з
is different depending on its maker.
Please refer to the antifreeze agent maker for the expansion rate
з
before calculate the
upper limit water volume of the system.

. The lever would turn down and indicate “0”,
if it functions normal.
•
Contact authorized dealer if the RCCB
