connected directly to a waste pipe via the reject water hose
(2), while the purified water is led out via the solenoid valve
(1). When in use, the initial volume of water in each
operating cycle is led off to the reject water hose via an
airlock. After this the purified water then flows through the
solenoid valve to some other appliance or item of ancillary
equipment which needs purified water.
The water purifier must be connected to an earthed
electrical supply (230V, 50Hz, 10A). We recommend use of
a plug-in connection to a wall socket, since certain
procedures such as replacing filters, preparing the appliance
for storage and, if necessary, moving it require the power
supply to be disconnected, then reconnected. Make sure
that the plug-in connector is easily accessible in order to
make these manoeuvres easier.
Connecting the reject water hose
Two hoses must be connected to the reject water outlet.
The straight end of the grey reject water hose, see diagram
C (for concentrate during operation and for flushing
water), is connected to the reject water outlet.
The hose can be extended up to 4 metres. The smallest
internal diameter for coping with volumes of up to 10 litres
per minute is 13 mm. The hose must be fed in an arc to a
height of no less than 50 mm and no more than 500 mm
above the roof of the water purifier. Use one of the two
hose clips to secure the hose to a drain, for example, if
required.
One of the hoses (3/8”, 2m polythene hose) for purified
water, see fig. C (for the initial water in each operating
cycle) from the solenoid valve connector which points out
from the water purifier, must be fed to the reject water
outlet.
In order to ensure that micro-organisms (bacteria) from the
reject water outlet do not grow back up the hose to the
water purifier, connection must be via an airlock, see fig.
C
.
Locate (screw on) the hose holder directly onto the reject
water outlet and feed the purified water hose through this,
creating an airlock of at least 50 mm between the end of
the hose and the reject water outlet.
Connecting the feed water hose
The straight end of the feed water hose must only be
connected to the cold water connector, see fig.
C
. The
water connector must be fitted with a cut-off valve.
Before connection, check that the black washers are in place
where the hose is connected. If the 3/4” hose connection
does not fit, then this can be changed to 1/2” using the
adapter supplied.
