Introduction
The EasiDoser™is an advanced microprocessor-controlled dosing system for dispensing a precise
amount of chemical. The dispenser features an electronic circuit board with an LCD display. Programming
is set using the keypad on the front of the unit and has a special pump ‘Lock-out’ that will prevent
consecutive dispensing. The EasiDoser™also has a “delay pump start”feature and a direct mode (Relay
Mode) which allows for a timed signal from a microprocessor to control the pump run timing.
The EasiDoser™is offered in various configurations: one, two or three low volume pumps, or an industrial
pump version.
Depending how the unit is programmed, the EasiDoser™ will activate when the circuit receives a 12-230V
AC or 12-24V DC machine signal through the Opto Isolator, or closed contact to one of the trigger inputs.
Also, it can be used for manual dosing and this is activated by pressing a button on the keypad.
Safety
The EasiDoser™Chemical Dosing System is designed exclusively for dosing chemicals by function of
Time, Time and Speed or Direct (Relay) mode in unrestricted pressure tanks. Any application outside the
use described in this operating manual will be taken to be not in accordance with the intended purpose.
The manufacturer/supplier will not be held responsible for any losses arising as a result of such use. The
user will take full responsibility for use.
USE IN ACCORDANCE WITH THE INTENDED PURPOSE ALSO INCLUDES COMPLYING WITH THE
OPERATING MANUAL AND THE CONDITIONS FOR INSPECTION AND MAINTENANCE.

Installation (refer to Fig.1, 2, 4)
Electrical Installation - should ideally be carried out by a Qualified Electrician –The 3-core power supply
cord MUST remain accessible when the unit has been installed and MUST be connected to Earth. THIS
ELECTRICAL SUPPLY SHOULD BE PROTECTED BY AN APPROPRIATE EARTH LEAKAGE CIRCUIT
BREAKER.
CAUTION: To avoid severe or fatal shock, always disconnect main power when
servicing the unit.
Chemical –is sucked up from a chemical container by peristaltic pump(s). The enclosure housing the
EasiDoser™pump(s) is rated at IP44 (IEC 60529); the power unit (A) must, therefore, be positioned in a
dry location and close to a 220-240V AC power socket (Maximum Power consumed: 50W).
The enclosure (A1) should be positioned no more than 2 metres vertically above the floor and no more
than 3 metres distant from the chemical container(s). Use the drilling template to mark out screw positions
and fix the enclosure to a suitable flat surface, using the screws and plastic plugs supplied.
The chemical container(s) (D) should be placed securely on the floor and the inlet tube(s) (C) from the
pump enclosure should be connected to the inlet nipple(s) of the peristaltic pump(s) –each PVC inlet tube
should be measured for correct length (cutting the excess tube) and warmed before being pushed over the
peristaltic pump spigot and secured with the stainless steel hose clips. Make sure that clips are fitted so
that the barb of the fitting on the pump is central in the clip and do NOT over tighten the clip (you risk
breaking the plastic nipple). Drop the filter end of the inlet tube(s) into the chemical container(s) –
ALWAYS ENSURE that each inlet tube has a FILTER FITTED.
CAUTION: Wear protective clothing and eyewear when dispensing chemicals or any
other materials. Observe safety handling instructions (MSDS) of chemical manufacturers.

Opto Isolator Connection
For volts-free signal (switch) there is no requirement for Opto Isolator and the switch can be connected
directly to the inputs marked on the PCB as Opto 4 & Opto 5. For a 12-24V DC signal or 24-230V AC
signal unit, the signal MUST be connected via the Opto Isolator(s) supplied with the unit.

menus detailed below.
Pumps are driven by low voltage DC motors and their time or speed of operation is controlled by the voltage
applied to each pump motor in order to ensure that the pumps are dispensing the correct quantity of
chemical(s).

If Optional Level Probes (e.g. AFF/200-50-10 –Float Switch Assembly for 20-25 Litre Container) are fitted,
LOW level of Chemical activates Float Switch as below:-
Sounder will operate 3 times every 2-3 seconds.
Sounder sequence will continue to operate at 1 minute intervals.
Warning Displays (as shown above) will alternate with the normal run displays.
When the container is refilled/replaced, the Sounder and Warning Displays stop automatically only
when the pump makes its first Dispensing cycle after refill.
Sounder CANNOT be muted until level of Chemical rises above “LOW”.
Initial Set Up –Priming & Setting up the system ready to use
Switch on the power at the electric socket and on the front of the pumping unit. Set the program for direct
mode. Press the appropriate button in the front of the unit to activate the required pump and liquid will start
to be drawn up through the pump(s). Allow unit to run until liquid has passed through the pump(s) and is
flowing out in a continuous stream from the end of the distribution pipe. Reset the direct mode to your
required setting.
Operation
Depending on the set up of the unit the pump(s) will either run for a set duration or continuously until the
signal is removed:
Manual mode –pressing the dose button for 1 second activates for a set duration.
Signal mode –receipt of either a 12-24V DC or a 12-230V AC signal activates for a set duration.
Direct mode –receipt of either a 12-24V DC or a 12-230V AC signal activates the unit and it will run
continuously until this signal is removed.
WARNING –Refill chemical container(s) BEFORE IT IS EMPTY and SWITCH OFF PUMP
UNIT whilst refilling. In the event that chemical supply is exhausted, it will be necessary to re-prime
system as described in the “Initial Set Up section” above.
Maintenance
In order to preserve the efficiency and reliability of the EasiDoser™ system, we recommend that the
following parts be inspected regularly for physical wear and replaced EVERY 1 –2 YEARS, depending on
the chemical used and the frequency of use.
Peristaltic pump tubes - Grease the tubes with silicone every six months
Inlet tube filters (part ATS/419). - Clean regularly with warm water
For optimum results and safety use all the parts supplied by the manufacturer.
