7. Device for filling and venting the solar installation
7.1. Device's description
Professional station for rinsing, filling, venting and servicing closed-circuit solar systems, heat pumps, floor and wall heating. The
device is used for quick and reliable filling of the thermal solar systems as well as others cold/hot water and glycol mixture systems.
The device eliminates the formation of air bubbles and decontaminates the installation.
Application: solar systems; heat pump systems; central heating systems; boilers / heat exchangers.
The device consists of the following elements: a trolley on stable wheels made of powder coated steel; strong, efficient pump;
polythene tank with a capacity of 30 l; transparent pressure hoses which allow for strophic control as well as eliminate the aeration
of the returning factor; ball valves for connecting hoses; cleanable, external filter.
7.2. Start-up
As the pump used in the device is not a suction pump, it must be filled with water before first use. This is done by filling the device's tank or the cup on the
pump. Before start-up, carefully check all hoses and connections (each filling station is pressure checked).
Do not fill the solar installation during sun exposure. The solar system can develop a temperature above 100°C, filling the preheated
installation like this can cause damage (and the guarantee does not include this type of damage).

7.4. Filling and venting the solar installation
The device's hoses are connected to the sockets marked as "Filling" and "Emptying" in the drawing below. When filling, it is important that the ball valve
on the rotameter is closed and to turn on the pump while filling the solar system (switch to manual mode on the solar controller). During the filling it is
recommended to vent the installation through the manual air valve located in the 4-way coupling near the solar collectors.

to 8 l/min
Caps for the valves:
After filling and starting-up
the installation wind up the
caps on the valves in case of
accidental opening.
Emptying
(1) – Filling the installation:
Attach the hose to tip of the filling valve, close the
rotameter's ball valve (regulatory), open the filling
valve and the drain valve, fill the installation.
(2) Start-up:
Open the ball valve and close the filling and drain valves. The connectors of the
filling and draining valves can be removed.
(3) – Adjust the flow rate until the correct flow is
shown on the flowmeter.
Attention: The correct flow rate reading is the one
on the lower edge of the disc/cursor (as shown in
the drawing above).
