2.7 Installation
2.7.1 Transport
 Choose the correct way of conveying the equipment.
 Try to transport the equipment with the original package.
 The main unit should be put down gently during transportation, and main unit should not be
leaned more than 45 degree.
 Guard boards should be applied to avoid scratching and deforming of the unit surface.
2.7.2 Main unit installation
Location of outdoor installation
 After move onto installing site, please confirm the main unit is placed in horizontal.
 Do not install the heat pump close to inflammable gas source.
 Do not install the heat pump close to a road or path to protect the appliance against mud
splashing.
 Avoid places that are subject to strong winds, in particular if the wind blows against the
appliance’s air outlet.
 Ensure enough space for installation and maintenance.
 A distance of no less than 200mm should be preserved between the bottom of the outdoor
unit and the ground or bracket for the installation of the duct pipe.
 If the unit installed in an underground chamber, an indoor room or other hermetic place, pay
attention to where surrounding air, as well as which air exhaust and air circulating system.
For every signal unit, which circulating air volume shall no less than 2400m3/h.

2.7.3 Water system piping
Pipe installation notes
 During installation of pipe connection, make sure no dust or other impurities is intruded into
the pipeline system.
 Water inlet and outlet pipes can be installed as long as the heat pump water heater has been
fixed.
 Thermal insulation materials should be employed to seal up water outlet and inlet pipes.
 The water inlet and outlet pipeline cannot be installed until the water heater is fixed well.
 Before operation, please confirm that the specifications of connective pipes are correct, and
thermal insulation layer have been wrapped on pipes. It requires that all pipes have been
sealed up, and no water leakage has been detected.
