5.8 Power Supply
The MonoSolar requires a 230 volts, 3 Amp, earthed electrical supply via either a
standard plug, or switched fuse spur.
5.9 Filling the System
5.9.1 Remove the plug on the T-piece.
5.9.2 Open the water level drain valve at the riser pipe. This level is the filling level
(see Fig 5.5).
5.9.3 Connect the filling hose to the filling tap connection and open the tap. Fill the
appliance with clean drinking water. You can hear the tank filling up. When the
noise reduces, the tank is nearly full. At this point the filling tap can be partially
closed. When the tank is sufficiently filled, water will run out of the drain valve.
Close the filling tap and remove the hose.
NOTE Do not overfill the tank, otherwise the expansion air gap would be reduced.
5.9.4 Close the drain valve and replace the plug on the T-piece.
5.9.5 Ensure all connections are watertight.
5.9.6 If a drain back vessel is fitted, then keep the hose on the filling tap when the
MonoSolar is full. Close the drain valve and replace the plug on the T-piece.
Open the valve tap on the bottom of the drain back vessel and patiently fill up
the system from the filling tap on the MonoSolar. Close the filling tap when the
water is no longer filling (ie. water starts to flow out of the vessel valve tap).
Remove the hose and close the valve tap when the flow from the vessel valve
tap has stopped.
PLEASE NOTE!
If the MonoSolar hasn’t got a filling tap, then a 8mm copper tube with a filling hose can
be fitted temporarily to the filling connection. In this case, disconnect the thermostat
tube temporarily to allow air to escape from the appliance.
5.10 Commissioning
Warning:
Do not connect the MonoSolar electrically until it has been charged with water!
Remove plug in the end of the pump and ensure that pump shaft rotates freely.
Replace plug.
When you electrically power the MonoSolar, the pump will run continuously for 5
mins. The pump will run on full capacity for a couple of minutes to fill up the panel
with water, then the standard pump speed will be selected. If there is sufficient
daylight, the pump will continue running. When the solar panel temperature increases
sufficiently, the pump speed will also increase.
Please note:
Check the installation and the solar panel circuit for leakage.
Warning:
Do not disconnect the electrical supply when the MonoSolar is operating.
