Installation
Select a suitable location avoiding locations where the system could come into contact
with things like hot water pipes, also consider ease of maintenance.
Check where the faucet (tap) will be installed looking at things like possible damage to
pipes and electrical wires when drilling, choose a location that will be the most
convenient for use.
Choose a location for the storage tank, the tank can be more remote than the main filter
system, a back corner cupboard is often used, the tank tube line is 1.8 metres, try
to have as short a tube to the tank and faucet as practicable because the shorter
the tube the faster the flow will be.
All tube is colour coded for installation ease
Blue tube connects from the mains supply to the entry point of the unit.
Yellow tube connects the main filter unit to the storage tank.
The black line connects the main filter unit for waste to the sink drain, this waste
line can be run outside to be collected for use in the garden.
The white line connects the main filter unit to the faucet (tap)
The mains connection best suited to your installation will have been selected at the time
of ordering, separate instructions are supplied with the mains connection kit, use
the supplied plumbers thread tape on all threaded joints, connect to cold water
mains supply only.
Faucet Installation
The RO water faucet may be installed on any flat surface at up to 50 mm [2”] in
