Installation Introduction

Connection of Pipeline

Please refer to the following system sketch map.
1.Measure the distances from the collector circulation water inlet to the tank circulation
water outlet, and from the collector circulation water outlet to the tank circulation water
inlet.
2.Prepare corresponding pipe fittings according to the measured dimension, and equipped
with the thermal insulating layer.
3.Connect the collector circulation water inlet and the tank circulation water outlet, as well as
the collector circulation water outlet and the tank circulation water inlet by the prepared
pipe fittings.
Note:
1.Counter slope shall be avoided in the connection of the pipeline.
2.The connection of the pipe fittings shall be correct and tight.
3.The circulation pipe shall be installed in a nice and neat way.
4.If insulation is required, the full length of the solar hot and solar cold pipes MUST BE
insulated. The insulation must be weatherproof and UV resistant.

Filling the Heat Exchange Jacket(For Indirect System)

1.Remove the 0.3MPa safety valve from the water tank. This is the fill level for the
transfer fluid and will allow air to escape during filling.
2.With the aid of a funnel and hose connected to the open service valve, pour water into the
funnel until water flows from the vent of the 0.3MPa safety valve.
3.Close the service valve tap and assembly the 0.3MPa safety valve.
4.Check for leaks at all connections.
5.If no leaks are evident, open the service valve tap, remove the 0.3MPa safety valve and add
in the supplied heat transfer fluid through the funnel. Water will be displaced as the heat
transfer fluid is added. Add a further 500ml of water to flush the heat transfer fluid through
the hose and into the collector.
6.Close the service valve tap, refit the 0.3MPa safety valve and ensure no leaks are present,
then move the hose.
7.The heat transfer fluid lever is to be checked every three(3) years by a competent technician.
