with applicable local codes and rules on installation and maintenance. We are not liable for any unit damage or

casualty due to non-conformance with this requirement.

■ The power supply must be switched off prior to maintenance and relocation of the unit; otherwise, personal

injury or death may be caused by electric shock. Do not touch such hot components as compressor and exhaust

pipe directly.

■ When the water system contains water, control the startup and shutdown of the water pump via the water pump

output point on the unit controller; otherwise, the anti-freezing protection of the unit will not work, causing the

freezing crack to the heat exchanger. If the unit is to idle for a long time in winter, drain the water from the water

system via the drain valve to prevent the freezing crack of the heat exchanger, the water pipe and other parts on

water side. Furthermore, the water pump shall be power off to avoid starting up against frost without water.

■ No unit is allowed to be installed near such places that are dirty, oily, salty, exposed to a large amount of sulfur

gas and where the unit parts may be subjected to corrosion, such as toilet vent, operation room vent and

sewage treatment equipment.

■ If the unit is operated below 0°C, it must be installed at a place at least 300 mm above the ground, so as to

avoid

icing of unit base plate and to ensure the normal operation of the unit even though the snow reaches this height;

in addition, the unit shall be placed on a plane (with maximum deviation per meter of not more than 2 mm).
