Hot water outlet of water tank
Note:
Distance between indoor unit and water tank should not exceed 5m levelly and 3m
vertically. If higher, please contact with us. Water tank on lower and main unit on higher
side is recommended.
Prepare the materials according to the above joints dimension. If cut-off valve is installed
outside the room, PPR pipe is recommended to avoid freeze damage.
Waterway pipelines can't be installed until water heater unit is fixed. Do not let dust and
other sundries enter into pipeline system during installation of connection pipes.
After connection of all waterway pipelines, perform leakage test firstly. After that, perform
heat preservation of waterway system; meanwhile, pay more attention to valves and pipe
joints. Ensure enough thickness of insulated cotton. If necessary, install heating device for
pipeline to prevent the pipeline from freezing.
Hot water supplied from insulated water tank depends on pressure of water tap, so there
must be supply of tap water.
During using, the cut-off valve of cooling water inlet of water tank should be kept normally
on.

17.4 ELECTRIC WIRING WORK

17.4.1 Wiring Principle
General principles
Wires, equipment and connectors supplied for use on the site must be in compliance
with provisions of regulations and engineering requirements.
Only electricians holding qualification are allowed to perform wire connection on the
site.
Before connection work is started, the power supply must be shut off.
Installer shall be responsible for any damage due to incorrect connection of the
external circuit of the unit.
Caution --- MUST use copper wires.
Connection of power cable to the electric cabinet of the unit
Power cables should be laid out through cabling trough, conduit tube or cable
channel.
Power cables to be connected into the electric cabinet must be protected with rubber
or plastic to prevent scratch by edge of metal plate.
Power cables close to the electric cabinet of the unit must be fixed reliably to make
the power terminal in the cabinet free from an external force.
