TRIAL RUNNING & CAPABILITY
RUNNING AND CAPABILITY 8.
Before running, please check the following items first:
Correct installation of the system;
Correct connection of pipeline and wiring;
Leakage of the refrigerant pipeline tested;
Efficient drainpipe;
Complete insulation protection;
Correct earthing;
Correct power supply;
No obstacle outside the air inlet and outlet;
No air in the water pipeline and all valves opened;
Effective electric leakage protector;
Sufficient inlet water pressure ( ≥ 0.15MPa)
Three heating elements are included in the Unit: one heat pump and two electric heaters, which are installed
in the upper 1/4 and at the bottom of Unit.
All these three heating elements do not work together.
This Unit has two temperature sensors, which are installed at the upper 1/4 and bottom 1/4 of Unit.
The upper sensor tests the water temperature in the upper part of Unit (shown by display); the bottom
sensor tests the water temperature in the bottom part of Unit and controls the ON/OFF of Unit itself (the
temperature value is not displayed).
HYBRID Mode: In this mode, the system will adjust the working capabiities of e-heater and heat pump according
to the tank water temperature.
(Water outlet temperature range 38~70°C, running temperature -30~43°C).
E-HEATER Mode: In this mode, the compressor and the fan motor will not run but the e-heater works only.
(Water outlet temperature range 38~70°C, running temperature -30~43°C).
