Introduction
Thank you for purchasing this quality product. To minimise the risk of injury
we urge that our clients take some basic safety precautions when using this
device. Please read the operation instructions carefully and make sure you
have understood its content.
Keep these operation instructions safe.
Safety Instructions
- Clean, flush and replace filter cartridges regularly.
- Do not disassemble parts indiscriminately as this may cause leaks or damage.
- Do not use a power supply with an inappropriate voltage rating.
- Disconnect the mains plug and turn off the water tap before storing the machine for an extended period of time.
- Do not store or use the machine at an ambient temperature of 0 ℃ or below.
- Take care when installing or removing the cartridge or moving the machine.
Other instructions
-
When not in use, turn off the water supply and close the ball valve to prevent damage from water hammer. Uncontrolled water hammer can cause leaks and damage to the filter housing.
We accept no liability for damage caused by water hammer. -
In the event of a problem, disconnect the appliance from the power and water supply and contact a specialist. Replacing the filters may solve the problem.
-
The machine will vibrate slightly during the filtration process.
-
It is recommended to have the cartridges replaced by a specialist.
Caution!
Water hammer is a shock or pressure wave that occurs when flowing water is
suddenly forced to stop or change direction. If the occupants of a building
suddenly close a valve, a pressure wave will spread through the building’s
pipes.
