Installation instructions
2. Pipeline connecting
Installation notes:
1
Water drain pipes, overflow pipes should be installed next to the drainage inlets to
facilitate drainage, vent valve should be installed on vent pipes.
1
Repair valve should be installed in front of the electromagnetic valve on the pipeline
system, which is convenient for future repair.
1
User water pressure should less than 0. 6 Mpa.
1
All pipelines should choose metal pipe (such as stainless steel, with Lining Plastic and
lining stainless steel and thin-walled copper pipe or, etc.). The use of plastic pipe
(such as the PP-R, ABS, etc.) should consider the pipeline expansion between the host
unit and water tanks .
1
Water supply and pause valves may need to keep warm in the winter (according to the
local winter temperature) to avoid the broken of water supply and pause valve.
Water system installation
1
All the pipeline tubing should be matched as shown on the manual, and in accordance
with national corresponding construction standards.
1
Installation of water pipes should be straight and flat, pipeline collocation should be
rational, ensure to minimize bending; reduce the resistance loss of the water system.
1
Pipeline and connecting parts are not allowed a leakage phenomenon.
1
After the installation of circulating pipe between tap water pipes, host unit and water
tanks ,should carry out water leakage testing, and eject the sewage to ensure the sy
stem's cleanness.
1
If no water leakage, keep the hot water pipe warm.
3. Project example:
Application of heat pump water heater engineering systems have different forms. Here
are a sample of one heat pump connect to the water tank to offer hot water, only for your
reference.
