1. Introduction
The Easyush Direct valve provides electronic ushing of the WC without the need for a WC cistern. There
are two versions:
Easyush Wave is operated by the user bringing their hand towards the infrared sensor. A part ush is
triggered by holding the user’s hand in place for 1 second; a full ush is triggered by a hand pass of over 1
second. The dual ush setting is a factory default but can be changed by the installer.
Easyush Direct Walkaway is activated when the user stands up or leaves the cubicle but it can also be
activated by the user bringing their hand toward the sensor. The dual ush setting is a factory default but
can be changed by the installer. A part ush is triggered by short user occupancy and a full ush by long
user occupancy (over 45 seconds).
With Easyush Direct there is no cistern to be relled; this means a second ush can be activated without
a delay. The product includes a hygiene rinse function.

2. Installation
IMPORTANT: Read this before tting the WC valve.
Flushing directly from the mains water supply
When ushing WCs or urinals directly from the mains, the Water Regulations require that the water supply
be protected by a suitable category 5 protection method or device.
In the case of WCs, this can be achieved in three ways:
1 The use of a dedicated supply for ushing use only, supplied from a break tank that protects the mains
supply with a type AA, AB or AD air gap.
2 The use of a specic type of WC bowl which has been tested and shown to incorporate the equivalent
of a type AB air gap.
3 The use of a type DC pipe interrupter (supplied with all Cistermiser Direct Flushing products).
A note about type DC pipe interrupters
These devices have an integral air gap; it is therefore important that pipework design and WC bowl
selection are appropriate to ensure sucient ow to ush the WC while preventing water owing back up
and out of the air gap.
The DC pipe interrupter must be installed not less than 150mm above the spill over level of the WC pan.
Ensure you follow these key design & installation points
• Install the valve as high as possible above the WC bowl.
• Install a free-owing, low restriction connection from the valve to the WC bowl. Ensure the water system
can deliver min. 90 lpm.
• Use a large pipe size in the pipework between the DC pipe interrupter and the WC.
• The DC pipe interrupter is tted with a 100 lpm ow regulator to control the ow of water; if you still have
issues with the DC pipe interrupter overowing, it may be necessary to install a further ow restricting
device upstream of the valve.
NOTE:
For grey water/rain harvesting. Ensure
adequate ltering is tted, a 10μm lter is
recommended. NOTE:
For chemical water treatment. If the water
system had been treated with chemical dosing,
ensure the system is thoroughly ushed before
tting any Cistermiser products. Concentrated
chemicals in dead legs can damage the
product and result in failure. If the water is
treated with Chlorine Dioxide (ClO2), ensure
concentration levels are maintained below
5ppm.Ensure adequate ltering is tted, a
10μm lter is recommended.
NOTE:
As with all water containing products, limescale
in hard water areas can aect the products
performance. This can result in maintenance
to remove the limescale when required.Ensure
adequate ltering is tted, a 10μm lter is
recommended.

3. Installation schematic
The valve must be installed at least
150mm above the spill over level to
comply with Water Regulations.
When installing the valve it is good
practice to ensure there is an
accessible isolating valve upstream of
the valve.
Ensure ow rate at valve
A
does
not exceed the ow rate to the WC
bowl
B
to prevent water backing-up
to the DC pipe interrupter.
A 1.5m extension cable is supplied if
required for placement of sensor.
NOTE:
Flush pipework prior to installation.
Do not install opposite a mirror. When
installed opposite a shiny surface, the
range may require adjustment. See
section 8 Advanced settings guide.

NOTE:
Removing the DC pipe interrupter may
contravene the Water Regulations (see page 3).
NOTE:
If you wish to connect to a 2" ush pipe, an
adapter can be purchased from your local
plumbing merchant.
Easyush Direct is supplied with a DC pipe interrupter. Fit the DC pipe interrupter to the valve outlet
ensuring the rubber seal is in place.

connection (not supplied).
If the DC pipe interrupter is not required
(see ‘Flushing directly from the mains water
supply’ in Section 2), t a 1.5

4. Power Connections
Fasten the mains adapter into place on the panel in a dry location using the screws or adhesive pads
provided and connect the un-terminated mains cable to a 50Hz 230V AC single phase supply via a 1A
fused spur (not supplied).
Connect the spade connectors from the sensor to the solenoid terminals; take care to connect the wires
according to the colour coding on the label. If the wires are not long enough they can be extended by up
to 1.5 metres with the cable supplied.
NOTE:
Remove the label from the sensor BEFORE
connecting to the power. When the power is rst
connected the LED in the sensor ashes amber.
This is normal and lasts only a few seconds.
Power connector
DMA55 power supply included with Easyush
Direct (Requires 1A fused spur)
Additional conguration options
With the Infrared conguration unit (ICU) remote control (sold separately).
• Hygiene rinse on/o. The installer is able to switch the 12 hr hygiene rinse function on or o.
• Clean mode. The Easyush Direct can be disabled for a short period to allow for cleaning.
• Siphonic trap rell mode. When activated this allows a small ush after every ush to rell the siphonic trap.
• Toggle wave feature on/o.
Electrical connection
Connect the power connector from
the sensor to the
mains adapter.
Alternative power options
For multiple connections the Cistermiser
power supply unit (PSUC) can be
used to power up to 20 units
(not supplied).
NOTE:
When using a Cistermiser power supply unit
(PSUC), ensure that when connecting correct
polarity is ensured.

5. Configuration
IMPORTANT: Water Flow Rate Requirement
To achieve an eective and ecient ush, the water system needs to deliver at least 90 lpm. Typically this
would require that the dynamic/working water pressure, measured before the valve, is at least 2 bar.
To comply with the water regulations the full ush volume must not exceed 6 litres.
The Easyush Direct is tted with a 100 lpm ow regulator* that will limit the ow through the valve to
100 lpm.
The ush duration is set by default to 3.5 seconds, this ensures the ush volume will be below 6 litres.
The part ush will automatically be set to 0.6 x the full ush duration. This will ensure the part ush
volume is less than 2/3rd the full ush volume as specied in the Water Regulations.
To adjust the ush duration and therefore the ush volume see Section 8 ‘Advanced settings guide’
The ow rate can also be reduced by turning the adjuster screw in the middle of the valve (clockwise to
reduce ow) or by tting a third party pressure reducing valve above the Easyush Direct.
Ensure that the dynamic water pressure (pressure measured while the valve is open and water is owing)
is sucient to achieve the required ow rate.
*Alternative ow regulators are available. Please contact Cistermiser.
WARNING:
The use of several other appliances from the
same water supply simultaneously may reduce
the ow rate below 90 lpm.
NOTE:
On smaller pipe sizes please pay particular
attention that you achieve 90 lpm at the valve
outlet for an eective ush.

6. Usage advice and specification
Minimum working pressure: An eective and ecient ush is achieved with a ow rate of >90
lpm. A typical installation will require 2bar dynamic pressure,
measured before the Easyush Direct, to achieve 90 lpm.
Maximum working pressure: 5 bar
Back siphonage protection: Class 5, Type DC
Factory settings
Range: EFD Wave – circa 18cm
EFD Walkaway – circa 65cm (9cm for hand activation)
Full ush duration: 3.5 seconds
Part ush duration: 2 seconds
Power requirements: 6V DC regulated from mains adapter (1A fused spur required)
Cleaning: Clean with soap and water only
Lens care: Infrared lens can be polished with a soft cloth
Electronic specication
Control classication: Independent
Maximum load: 2W, 0.33A (6VDC)
Rated temperature range: 0-40 deg C
Ingress protection: IP65
NOTE:
When using the Easyush Direct valve from a mains water supply, the pressure may be higher than is
suitable for the design of the bowl which can cause splashing to occur. In such cases t a ow regulator
(supplied) as indicated in Section 5.
