Your FLEXFLO A3 pump is pre-configured for the tubing that shipped with your
metering pump. The tubing assembly has an Identification number printed for
easy re-order.
Please Note: Your new pump has been pressure tested at the factory with
clean water before shipping. You may notice trace amounts of clean water in the
pre-installed tube assembly. This is part of our stringent quality assurance pro-
gram at Blue-White Industries.

FLEXFLO A3 5.0 Installation
5.1 Mounting Location
1. Choose an area located near the chemical supply tank, chemical injection point, and electrical supply. Also,
choose an area where the pump can be easily serviced.
2. Finding a secure surface and using the provided mounting hardware, mount the pump close to the injection
point. Keep the inlet (suction) and outlet (discharge) tubing as short as possible. Longer discharge tubing
increases back pressure at pump head.
NOTE: Mounting the pump lower than the chemical container will gravity-feed chemical into it. This “flooded
suction” installation will reduce output error due to increased suction lift. A shut-off valve, pinch-clamp, or
other means to halt gravity-feed to the pump must be installed during servicing.
NOTE: Install a back flow prevention check valve at the discharge side of the pump to prevent the system fluid
from flowing back through pump during tube replacement or during tube rupture.
NOTE: It is recommended to have a pressure relief valve at the discharge side of the of pump to prevent
premature wear and damage to the pump tube, in the event that the discharge line becomes blocked.
NOTE: The does not require back pressure. Keep the discharge pressure as low as possible to maximize pump
the tube life.
All diagrams are strictly for guideline purposes only. Always consult an expert before installing
metering pump on specialized systems. Metering pump should be serviced by qualified persons
only.
Always wear protective clothing, face shield, safety glasses and gloves when working on or near
your metering pump. Additional precautions should be taken depending on solution being
pumped. Refer to MSDS precautions from your solution supplier.
Risk of chemical overdose. Be certain pump does not overdose chemical during backwash and
periods of no flow in circulation system.
Be sure that installation does not constitute a cross connection with drinking water supply.
Check your local plumbing codes.
The pump should be serviced by qualified persons only. If equipment is used in a manner not
specified in this manual, the protection provided by the equipment may be impaired.
The pump should be supplied by an isolating transformer or RCD (operating current less or
equal 30 mA).

Risk of electric shock - All
wiring must be insulated
and rated 300V minimum.
!
WARNING
Shielded cables should be used on all input signal wires.
5.0 Installation
5.3 Input Power Connections
Risk of electric shock – cord connected models are supplied with a grounding
conductor and grounding-type attachment plug. To reduce risk of electric shock, be
certain that it is connected only to a properly grounded, grounding-type receptacle.
WARNING
!Be certain to connect pump to proper supply voltage. Using incorrect voltage will damage
pump and may result in injury. Voltage requirement is printed on pump serial label.
!Input power range is 96VAC to 264VAC 50/60 Hz.
!Voltage Selection is automatically detected and adjusted by power supply. No mechanical
switch necessary.
!Use voltage your power cord is rated for.
!Power cord models are supplied with a ground wire conductor and a grounding type attach-
ment plug (power cord). To reduce risk of electric shock, be certain that power cord is con-
nected only to a properly grounded, grounding type receptacle.
!Be sure all M12 wiring cable glands are properly installed and sealed.
!Never strap control (input / output) cables and power cables together.
!Power Interruption: This pump has a user programmable auto-restart feature which will can
either restore the pump to the operating state it was in when power was lost or require a user
action to restart.
Note: When in doubt regarding your electrical installation, contact a licensed electrician.
Electrical connections and grounding (earthing) must conform to local wiring codes.
WARNING
Risk of electric shock - Disconnect electricity before removing the wiring
compartment cover.

Risk of electric shock - All
wiring must be insulated
and rated 300V minimum.
!
WARNING
Shielded cables should be used on all input signal wires.
5.0 Installation
5.3 Input Power Connections
Risk of electric shock – cord connected models are supplied with a grounding
conductor and grounding-type attachment plug. To reduce risk of electric shock, be
certain that it is connected only to a properly grounded, grounding-type receptacle.
WARNING
!Be certain to connect pump to proper supply voltage. Using incorrect voltage will damage
pump and may result in injury. Voltage requirement is printed on pump serial label.
!Input power range is 96VAC to 264VAC 50/60 Hz.
!Voltage Selection is automatically detected and adjusted by power supply. No mechanical
switch necessary.
!Use voltage your power cord is rated for.
!Power cord models are supplied with a ground wire conductor and a grounding type attach-
ment plug (power cord). To reduce risk of electric shock, be certain that power cord is con-
nected only to a properly grounded, grounding type receptacle.
!Be sure all M12 wiring cable glands are properly installed and sealed.
!Never strap control (input / output) cables and power cables together.
!Power Interruption: This pump has a user programmable auto-restart feature which will can
either restore the pump to the operating state it was in when power was lost or require a user
action to restart.
Note: When in doubt regarding your electrical installation, contact a licensed electrician.
Electrical connections and grounding (earthing) must conform to local wiring codes.
WARNING
Risk of electric shock - Disconnect electricity before removing the wiring
compartment cover.

Four points on the slope must be defined:
1) a low mA value
2) an output rate at the low mA value
3) a high mA value
4) an output rate at the high mA value
Default settings: 4mA = 0% motor speed
