Network Adaptor and Installation (Optional)
12.1.6.1
1.
Open the Cabinet front plate, then connect the
Network Adaptor
Cable
to the CN-CNT
connector on the printed circuit board.
o
Pull the cable out of the Mono bloc unit so that
there is no pinching.
o
If an optional PCB has been install in the
Mono bloc unit, connect the CN-CNT
connector to Optional PCB.
2.
Insert a flat head screwdriver into the slot on
the top of the
adaptor and remove the cover.
Connect the other end of the
CN-CNT cable
connector to the connector inside the adaptor.
3.
On the wall near the Mono bloc
unit, attach the
adaptor by
screwing screws through the
holes
in the back cover.
4.
Pull the CN-CNT cable through
the hole in the
bottom of the
adaptor and re-attach the front
cover to the back cover.
5.
Use the included cord clamp to fix the CN-

connector in the adaptor. Use the included
cable tie to fix the cables together.
Base Pan Heater (Optional)
12.1.6.2
It is strongly recommended to install a Base Pan Heater (optional) if the Mono bloc unit is installed in cold climate
area. Refer the Base Pan Heater (optional) installation instruction for details of installation.
12.1.7 Charging the Water
Make sure all the piping installations are properly
done before carry out below steps.
1 Open Cabinet front plate to access to the
Pressure Relief Valve and Air Purge Valve.
2 Turn the plug on the Air Purge Valve outlet
anticlockwise by one complete turn from fully
closed position.
3 Set the Pressure Relief Valve level “DOWN”.
4 Start filling water (with pressure more than
0.1 MPa (1 bar)) to the Mono bloc unit via
water inlet. Stop filling water if the free water
flow through Pressure Relief Valve drain hose.
