The OSO MINI can be fitted vertically or horizontally to suit the particular application.
For vertical mounting rotate the bracket on the back of the cylinder through 180°. For horizontal mounting use the semi-circular bracket provided.
IMPORTANT: before resetting the safety cut-out or altering the thermostat setting, isolate electrical supply to the unit prior to removal of the lid.
Ensure the lid is replaced correctly and the retaining screws are fitted. The retaining screws are at the front and back of the cover.
If higher temperatures are required, thermostat operating between 45°C and 75°C are available from OSO Hotwater (UK) Ltd. Part No. 80020.

Water Connections
Cold inlet and hot outlet are 15mm.
The water heater can be connected directly to a mains cold water supply or to a supply to a cistern tank,
provided that:
(a) There is no reverse flow restriction
(b) The cold water supply does not exceed 6 bar
(c) The hot water that has expanded back down the cold feed pipe cannot enter a supply pipe to which a cold
draw-off is connected
Electrical Connection
The mains cable is factory fitted.
The electrical connection to the immersion heater must conform to current IEE wiring
regulations. The unit must be permanently connected to the electrical supply through a double
pole linked switch with a minimum break capacity of 13 amps. All internal wiring is factory
mounted. The immersion heater has a working thermostat adjustable between 30°C and 60°C.
A safety cut-out is also incorporated within the thermostat and will operate at 85°C ± 3°C.
Should this happen, press the reset button.
Horizontally gives more hot water.
