INSTALLATION
(8) Mount the pump on a tank/surface using mounng bracket and nut-bolts provided and ghten
the nut-bolts properly.
(1) Always wear protecve clothing, face shield, safety glasses and gloves when working on or near
your metering pump. Addional precauons should be taken depending on the soluon being
pumped.
(11) Aer cung an appropriate length of tubing, connect tubing to injecon valve and then back to
the discharge side of the pump head.
(13) Connect the nozzle on the pump to the injecon valve.
(4) Sucon li -: Sucon li should be less than 1.5 meter for soluons having a specific gravity of
water, for denser soluons consult factory.
(10) The sucon nipple will be on the lower side with the sucon tubing being immersed completely
in the dosing liquid.
(3) Flooded sucon -: The pump is mounted at the base level of the storage tank. This installaon is
most trouble free and is recommended for low flow output and high viscosity soluons. Since
sucon tubing is filled with soluon, priming is accomplished quickly and chance of losing prime
is reduced.
(6) The valve is designed to submerge in the soluon tank or drum and must sit in a vercal posion
at the boom. Posion approximately 2 inches off the boom if the tank or drum contains
sediment.
(2) Pump is to be protected from sun and rain. If outdoor installaon is unavoidable, provide a
canopy over the pump. Pump should be accessible for roune maintenance and should not be
subjected to ambient temperature above 50° C.
(7) Injecon valve prevents back flow from the main line. When installing the injecon valve, be sure
to posion it in vercal so that the valve enters the boom of the pipe line.
(5) The foot valve act as a check valve to keep the pump primed in sucon li applicaons.
(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 injecon valve to the
injecon pipe into which dosing is to be done.
(14) Plug the pump.

STARTUP
(5) Keep the ARV open unl the dosing liquid flows in a connuous stream in the tubing (without any
bubbles).
(1) Connect the mains supply.
(3) Switch on the mains buon 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 direcon to 100 (max. frequency seng 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 connecon 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 regulaons applicable at the installaon site should be
applied (e.g. wearing protecon clothing's). Observe the chemical manufacturer's safety data sheet and safety
instrucons when handling chemicals.
Ÿ The pump can not be used fin sub-merged condion.
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 sucon filter assembly, NRV body etc. ,
depends on the medium, media temperature and operang pressure. Ensure that the parts come contact with
the dosing medium are resistance to the dosing medium under operang temperature and pressure, see the
data booklet.
Ÿ Before starng 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 sucon 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 condion and put operator's in risk. The dosing medium/liquid is pressurized and can be harmful to
health and the environment.
6.Dismantle the sucon 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. Operang 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 operaon 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 sucon and discharge side.
