Air duct installation: A flexible connector should be installed between the unit
and air duct. The air duct should not bear the weight of the unit. Install a
support for an air duct, and ensure that the joint between an air duct and the
unit is not exposed to stress.
Pipe thermal insulation: Take thermal insulation measures for all inlet pipes
and drainpipes of the unit. Reserve sufficient space for maintenance and
operations when installing thermal insulation foam for valves and connectors.
At low temperatures, take thermal insulation measures to prevent water pipes
from freezing.
