Installation
• Remove temperature gauge.
• Remove insulating shell.
• Slide clip to release bracket, then reposition.
• Install the bracket to the wall using the mounting screws supplied
in the pack (1).
Insert the unit from the front, seating the pins as shown in the
figure.
The components are fastened to the bracket automatically by the
clip (2).
• Establish the position for installing an expansion tank (separately
purchased) at a distance allowed by the length of the hose (3).
• Install the piping for the entire system and connect the solar unit.
Secure the components and the pipes to the rear insulation.
Tighten all the fittings.
• The unit’s threaded fittings are tightened and tested in the assembly
phase in the factory. However, use a pressure test to check for
leaks during commissioning.
• Make the electrical connections of the system, as specified in the
solar controller instruction manual.
Apply the front part of the insulation.
Filling the system
• Open the shut-off valve coupled with the automatic air vent,
installed at the highest point of the solar thermal system.
• Open the shut-off and check valves, located where the temperature
gauge(s) insert.
• Fill by with a pump, using the valve (A) located at the lowest point
of the system, until air no longer comes out of the air vents. If the
solar thermal system requires the use of glycol-water solution top-
off the system using the same glycol-water mixture.
• Close the air vent shut-off valve.
