Multi-Function Water To Water Heat Pump
7.4 Wiring construction must be installed by professional technicians refer to circuit diagram.
7.5 Power lines and signal line layout should be neat, rational, strong and weak lines separate and can
not interfere with each other, while not contacted with the connecting pipe and the valve body.
7.6 When power lines and control lines parallel, the wires were placed in each tube, also leave appropriate
distance between the lines.
7.7 Unit electric wire connection: take the unit power line, remote control three core lines, electric heater
power line, solar circulated water pump control power line, water tank temperature sensing line, solar
collector temperature sensor line, terminal equipments connect to unit lines, through the unit wiring
hole set into the electrical box, connect to the appropriate terminals according to wiring diagram, and
fix it by the pressure line of board in the electrical box.
7.8.Unit control panel Code MK3051, Fuse specifications: 5A/250V

.1 Voltage drop occur may due to the large current draw during compressor starting, and may be result
in the compressor is difficult to stat. So we recommend selecting the wire specification from the table
below.
