9. RUNNING AND CAPABILITY

9.1 Trial Run

Before start, please check the following first:
Correct installation of the system;
Correct connection of pipeline, wiring and earthing;
Drainpipe connected;
Suitable pipe insularion;
Correct transportation of unit;
Correct power supply;
No obstacles outside the air inlet and outlet;
Complete bleeding air out of hot water cylinder and pipes;
Effective electric leakage protector;
Sufficient inlet water pressure(≥150kPa)
9.2 Operating Capability
Water-heating Operating Capability
There are twotypes of heat sources that can be used by the
heat pump water heater: electric element and heat pump.
These two sources may work together at the same time.
This unit has two temperature sensors in the hot water cylinder,
they are installed at the upper 1/4 and bottom 1/2. The upper one
tests the upper temperature, shown in the figure below, and the
bottom one is used to test the lower water temperature, which
will control the operation of the heating automatically.
