About the Kwikwash I Series
—What makes this product
so unique and dierent?
The Kwikwash I Series uses innovative new
technology to deliver hot water instantly…
and achieve impressive eciencies in both
water and energy usage.
We’d like to explain how it’s so dierent from
other hot water systems – and why it’s setting
completely new standards.
To fully appreciate the dierence –
and the substantial benefits – oered by
the technology used in this water heater,
we need to start o by comparing the main
deficiencies of traditional hot water systems.
—Heating water the traditional way
Traditional centralised hot water services
consume continuous energy to heat water
and then maintain it at a defined (thermostat-
controlled) temperature, ready for when it’s
wanted. Typically, the water heater is located
away from where the water is wanted, relying
on lengths of pipe to deliver the water.
Energy is therefore wasted keeping quite a
large volume of water at a stable temperature
– often at a higher temperature than would
ever be used.
But that’s not all – water is wasted every time
a hot water tap is turned on. That’s because
you need “to let the water run” until the water
held in the pipes has made way for the hot
water you want, coming from the water heater.
The overall result is quite inecient usage
of power together with wastage of water.
—The Billi dierence
Billi set out to provide something completely
dierent from existing methods of supplying
hot water: a highly ecient new method of
heating water that would address the wastage
of valuable resources – energy and water.
The Kwikwash I Series is a very compact unit,
which provides an instant and continuous flow
of hot water wherever it’s required – delivered
through very short lengths of pipe. Water isn’t
wasted, because you’re not leaving it running,
waiting for it to get hot. Hot water is always at
a stable temperature, despite any fluctuations
in water pressure.
You don’t need a science degree to understand
how the eciencies and savings are achieved
– all you need to do is follow our simple
explanation.
—The secret of “optimised” energy
The unit intelligently optimises the amount
of energy it needs to heat water, depending
on how much water you want.
For example, let’s assume hot water
is required at 45°C.
If you want a fairly fast flow of water –
4 litres a minute – the unit will use its
full power – 9.6kW – to heat the water.
However, if you only want a low flow of
water – 1.5 litres a minute – the unit will
use just 4.2kW to heat the water.
The benefit is the unit can intelligently vary
itself between being a 9.6kW and 4.2kW
system. The lower flow rate achieves 56%
less energy consumption – and that
contributes to lowering power bills.
In addition, varying the flow rate of the water
contributes to lower water consumption and
achieves further savings. Reducing water flow
from 4 litres a minute to 1.5 litres a minute
lowers water consumption by 66%.

—Incoming water temperature
makes a dierence
The unit also achieves savings in another
area – by intelligently varying its power
between 9.6kW and 7kW to heat incoming
cold water.
Depending on where you’re located and what
season it is, mains cold water temperature
could potentially fluctuate anywhere between
10°C and 25°C.
Let’s again assume hot water is required
at 45°C and you want a fairly fast flow of
hot water – 4 litres a minute.
If the incoming water temperature is a fairly
chilly 10°C, the unit will apply its full power
of 9.6kW – however, if it’s a pleasantly warm
25°C, it will only use 7kW. That’s 20% less
energy consumption – making a further
contribution towards lowering power bills.
We hope you now have a better
understanding of how the Kwikwash I
Series is revolutionising hot water.
IMPORTANT: The unit does not contain
any user-serviceable parts. In case of
malfunction, please contact us on
03 9469 0400 and arrange a service
call to rectify the problem.
Although the Kwikwash I Series is very safe to use, this appliance
is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for
their safety. Children should be supervised to ensure that they
do not play with the appliance.

Getting Started
—Guided Tour
The unit will automatically begin operating
when you turn on a hot water tap, and water
is flowing faster than 1.5 litres a minute.
The output temperature of the water has
been pre-set to maximum of 50°C OR Other
Specified Maximum Setting <50°C and this
cannot be adjusted.
There are no manual controls – the LED
indicator will provide information to you
about the operational status of the unit.

—What does the LED indicator tell me?
The LED indicator on the Exterior Cover indicates the operational status of the unit,
based on these options:
LED INDICATOR
NOT ILLUMINATED
No electricity is being supplied to the unit.
SLOW FLASHING
GREEN
Standby mode, waiting for water to be turned on.
FAST FLASHING
GREEN
The unit is operating and water is being heated.
FLASHING RED The unit is self-diagnosing an error that it will attempt to resolve.
When the error has been resolved, the LED will return to slow
or fast flashing GREEN.
RED CONTINUOUSLY
SHOWING
Mechanical Lockout Mode (Irresolvable Error). This means
you’ll need to contact us on 03 9469 0400 and arrange a
Billi Service Technician to rectify the problem.
WARNING: In accordance with AS 3500,
this appliance will not deliver
temperatures exceeding 50°C.
Water temperatures greater than 50ºC can
cause scalding. Care should be taken with
children and people with limited sensory,
physical, and/or mental capability.
IMPORTANT: The unit does not have any
user-serviceable components internally,
and must not be opened.
If an irresolvable error condition is
displayed, please call Billi on 03 9469 0400
to arrange a service.

Operational Parameters
—Location
The appliance has an IP44 rating, which
means that the appliance is adequately
protected from the ingress of water.
However, it is required that the appliance
be installed within a dwelling or construction
where there is a decreased likelihood of
water entering the cover of the unit.
—Temperatures
As the unit is intended for internal installation,
it should not be in an environment where
there is a possibility of the ambient
temperature dropping below 5°C.
IMPORTANT: Where the ambient
temperature is likely to approach
freezing – ie: less than 5°C – the unit
must be drained of water to prevent
frozen water damage occurring.
Failure to comply with the installation
and operating instructions or improper
use voids the warranty.
If a drop in temperature below 5°C
occurs, or is considered likely to occur,
please call a Billi on 03 9469 0400 to
arrange a service.
—Maintenance
The unit is designed to provide long and
reliable service. Actual life expectancy will
vary with water quality and use. The unit itself
does not require any regular maintenance.
However, to ensure consistent water flow,
it is recommended that a licensed plumber
should periodically remove scale and dirt
that may build up in the Inlet Filter of
the unit, the faucet or in the shower head.
IMPORTANT: Other than the inlet filter, the
unit does not contain any user-serviceable
parts. In case of malfunction, please call
Billi on 03 9469 0400 to arrange a service.
IMPORTANT: If the power is cycled,
the unit will need to run for around
3 minutes before it will heat.
