PLACING 200TDHW
The place where the system will be installed should allow an easy access in order to make
maintenance work or inspection.
Beside these factors, it is important to take into account the following indications regards the
installation site:
-
The system has been designed and manufactured for it indoors utilization. In case the
system has to be placed outdoors, it must be protected against the adverse weather
conditions (direct solar radiation, rain, snow…)
-
Try to place 200TDHW as near as possible of the panels’ installation, and also near to the
buffer tank.
-
Installer must install the supplied Silent blocks to avoid the transmission of vibration.

CONNECTION BETWEEN 200TDHW AND PANEL
7.1.
Join refrigerant pipes
Panels are supplied with two nuts for the inlet and outlet connection. The inlet to each panel is 1/4
inch diameter. The installer has to insert the nut into the copper pipe, flare the pipe and then use the
nut to fit it.
Repeat the procedure with the outlet connection using 3/ 8 inch copper pipe.
Then, join the suction line that comes from the panel to the coolant inlet of 200TDHW, and the liquid
line to the coolant outlet. The connections are threaded, if welding is needed, weld by oxyacetylene
welding.
IMPORTANT (Only when welding is needed):
It is recommended to weld pipelines by oxyacetylene welding.
Welding is a critical step in the installation and to do it well ensures that the system will run properly
along its useful life.
Only expert staff should make this step by using proper tools and high quality materials.
7.2.
Nitrogen test and cleaning procedure
In order to check the tightness, introduce nitrogen by using the pressure gauge already installed into
load ports.
