1. Turn water supply on
2. Turn electrical supply on
On initial switchAon only
After a few seconds delay for the electronics to charge
up, the boiler will begin filling with water and the ‘Ready’
light will flash to indicate wait. If the key switch is in the
‘on’ position the push button will flash green to indicate
wait, at this point the button is disabled. When water
reaches the low level sensor (element covered) the
element will be energised as well as the solenoid. When
normal operating level is reached the solenoid will turn
off and the element will remain on until full operating
temperature is reached.
Figure 4 shows the approximate times for boiling water
to be available from switch on.

With the key switch in the ‘ON’ position the push button
will stop flashing and show solid colour when the boiler
is up to full temperature and the button will be enabled,
at this point the ‘ Ready’ light will stop flashing and show
solid colour and the ‘Full’ light will also be illuminated.
On subsequent operation of the boiler
The boiler will fill and heat in cycles. It will allow only
a limited amount of water to enter the unit at any one
time and then switch off the solenoid and energise the
element.
W4 USER INSTRUCTIONS
Boiling water is dispensed by operating the push button.
The button will only be useable when the key switch is
in the ‘ON’ position and illuminated solid green colour,
indicating that water is up to temperature. Due caution
should be applied as the water is at approximately
98˚ Centigrade at all times. The ‘Ready’ light will flash
when the boiler is not up to temperature and show
solid colour when at operating temperature. The ‘Full’
light will illuminate only when the boiler is at operating
temperature and also full capacity is available for
dispense. If all water is drawn from the unit the flow will
reduce to a trickle. The unit will replenish the supply in
cycles i.e. a small amount of water will enter the unit ,
which will subsequently be heated but all water available
will be at approximately 98 ˚ Centigrade.

Pipe-work should be fitted with a
continuous fall to a safe and visible point
of discharge (e.g. a sink).
It should not be
connected directly to a waste system
because taste and smell problems will
occur.
This installation allows the silicone hose
to fit loose inside a fixed fitting. Air is
allowed into the boiler at this point and
will allow the boiler to breath in the event
of the overflow becoming trapped.

WX
The boiler is supplied with a 3/4” BSP Water Research
Council approved flexible water connection hose. This
hose should be connected to the mains water supply
using an isolating valve and then fitted to the machine
solenoid valve inlet.
BX
The vent / overflow pipe should be extended on site
using 15mm Table X copper tube or ‘Speedfit ‘ plastic
pipe as described in Fig 3.
The overflow pipe must be
fitted and arranged such that the outlet position is
safeg visible and external to the boiler4 The overflow
pipe must not be connected directly to a soil pipe
and should never be allowed to become blocked or
restricted
