(4).Selection circulation pipeline.
Circulation pipeline of inverter heat pump can not be smaller than the inlet and outlet pipeline,
circulation pipe should use the same diameter as inlet and outlet pipes.
(5).Connection of pipeline
Don't let the dust and other debris into piping system.
Doing the plumbing work after fixing the unit firmly.
A removable filter
(
40
~
60mesh
)
must be installed at the water inlet and please
regular clean the valve depend on your local water quality.
Install a drain valve in the lowest point of the pipe, for convenient cleaning, Ensure
smooth access level, Can not alternately up and down, for discharge the air and
draining the water in the pipe out.
Install the union valve at the water inlet/outlet, for convenient maintaining. Should fix
the valve on water pipe of the unit. Rotating the water pipe, water connecting can’t
withstand rotation torsion directly.
Outlet and inlet water pipes should do thermal insulation well, the distance of outlet
and inlet need to apart, for first time to use, should add the appropriate amount of
antifreeze and anti corrosive into the warming water pipes, the input water pipe and
water tank can do water replenishment according to the actual situation.
Do not shut off the power in winter. If do not use for a long time, should drain off the
water in the unit and water pipes, to prevent heat exchanger or water pipe freeze and
crack.
Select pipe material, can choose stainless steel, copper, aluminum hot water pipes, hot
water PPR pipes, etc., with pipes in national health and safety standards,
heat-resistant, rust-proof, not easy to scale.
Reasonable pipe layout, to minimize bending and reduce the pressure loss of the
water system.
After the circulating water system connected, must do pipeline connection rigidity and
add water pressure inspection, and sewage, to ensure the system clean. Past the
inspection,no leakage, then pack insulation for pipeline and valves.
Metal pipe must use with more than 50mm thick glass fiber or high density,
fire-retardant insulation sponge. (PPR hot water pipes can be used 30mm thickness of
glass fiber or high density fire-retardant sponge rubber insulation.)
Must install thermometer and water pressure gauge on Inlet and outlet water pipes,to
inspect during operation.
