INSTALLATION
(8) Mount the pump on a tank/surface using mounng bracket and nut-bolts provided and ghten
the nut-bolts properly.
(1) Always wear protecve clothing, face shield, safety glasses and gloves when working on or near
your metering pump. Addional precauons should be taken depending on the soluon being
pumped.
(11) Aer cung an appropriate length of tubing, connect tubing to injecon valve and then back to
the discharge side of the pump head.
(13) Connect the nozzle on the pump to the injecon valve.
(4) Sucon li -: Sucon li should be less than 1.5 meter for soluons having a specific gravity of
water, for denser soluons consult factory.
(10) The sucon nipple will be on the lower side with the sucon tubing being immersed completely
in the dosing liquid.
(3) Flooded sucon -: The pump is mounted at the base level of the storage tank. This installaon is
most trouble free and is recommended for low flow output and high viscosity soluons. Since
sucon tubing is filled with soluon, priming is accomplished quickly and chance of losing prime
is reduced.
(6) The valve is designed to submerge in the soluon tank or drum and must sit in a vercal posion
at the boom. Posion approximately 2 inches off the boom if the tank or drum contains
sediment.
(2) Pump is to be protected from sun and rain. If outdoor installaon is unavoidable, provide a
canopy over the pump. Pump should be accessible for roune maintenance and should not be
subjected to ambient temperature above 50° C.
(7) Injecon valve prevents back flow from the main line. When installing the injecon valve, be sure
to posion it in vercal so that the valve enters the boom of the pipe line.
(5) The foot valve act as a check valve to keep the pump primed in sucon li applicaons.
(9) The discharge point marked with arrow should be always faces upwards.
(12) Use the remaining tubing on the discharge side and connect the back injecon valve to the
injecon pipe into which dosing is to be done.
(14) Plug the pump.

STARTUP
(5) Keep the ARV open unl the dosing liquid flows in a connuous stream in the tubing (without any
bubbles).
(1) Connect the mains supply.
(3) Switch on the mains buon and press the on-off key of the pump to start the pump.
(6) Close the ARV.
(2) Turn the frequency knob fully in clockwise direcon to 100 (max. frequency seng of the pump).
(4) Open the ARV (Air Release Valve) by approximately three-five turns.

ESSENTIAL SAFETY REQUIREMENT
Ÿ Install the pump in any shaded place away from direct sunlight.
Ÿ Electrical connecon should be made between Live – Neutral and Not live-Ground.
Ÿ Make sure that any chemicals that are released from the pump or any damaged lines do not causes damages to
system parts.
Ÿ Ensure voltage is within range specified for the pump i.e., 230 ±10% V.
Ÿ Avoid giving supply from the same line as heavy electrical equipment.
Ÿ When working with chemicals, the accident pretension regulaons applicable at the installaon site should be
applied (e.g. wearing protecon clothing's). Observe the chemical manufacturer's safety data sheet and safety
instrucons when handling chemicals.
Ÿ The pump can not be used fin sub-merged condion.
Ÿ The dosing medium must be a liquid, Observe the freezing and boiling point of the dosing media. The
resistance of the parts which comes into contact with the dosing medium, such as the dosing head, PTFE ball
and washer, glass ball, 'O' ring, ball bush, pipe lines, ball seal and sucon filter assembly, NRV body etc. ,
depends on the medium, media temperature and operang pressure. Ensure that the parts come contact with
the dosing medium are resistance to the dosing medium under operang temperature and pressure, see the
data booklet.
Ÿ Before starng work on the pump, the pump must be disconnected from the power supply. The system must
be pressure less.
Ÿ Before switching on the main supply, the tubing cap (both sucon and discharge valve assembly) should be
ghtened to dosing head properly so that the metering liquid can not spray out from the dosing head in
working condion and put operator's in risk. The dosing medium/liquid is pressurized and can be harmful to
health and the environment.
6.Dismantle the sucon and discharge tubing and check whether tubing is blocked, soiled or damaged, replace if
necessary.
Ÿ Do not operate the pump with a damage/break diaphragm. Operang with damaged diaphragm can lead to
dosing liquid entering pump housing. In case of diaphragm breakage immediately separate the pump from the
power supply. Make sure the pump cannot be put back into the operaon by accident. In case of diaphragm
breakage use the following step to dismantle diaphragm (refer fig. of Edose Dosing Head overview):
1.Make the system pressure less.
2.Empty the dosing head before maintenance and flush it, if necessary.
3.Set the frequency knob to 0%.
4.Switch off mains supply.
5.Take suitable steps to ensure that the returning liquid is safely collected.
7.Dismantle NRV body in sucon and discharge side.

8.Remove the ball bush and o ring from NRV body. Check their safety for wear and damage.
If necessary, replace them.
10.Remove the spring fing washer and nut and PTFE washer.
14.Check the diaphragm. If necessary, replace it.
9.Unscrew the PCB housing and remove it.
12.Remove the diaphragm washer, plunger washer and diaphragm o ring from diaphragm-plunger assembly.
13.Dismantle the diaphragm-plunger assembly
11.Loosen the screws on dosing head and remove the screws.
