explosive atmosphere, corrosive air, wet environment or submerged in fluid.
STH/Q SET UP INSTRUCTIONS
!
Caution! Fire, electrical shock, injury and damage may
occur if not used in accordance with Fluid Metering, Inc.
specifications and operation instructions.
Do not put wet fingers into power outlet of unit.
Do not operate with wet hands.
Do not operate drive assemblies that require a hard mount
(to be bolted down) unless they are mounted per Fluid Metering, Inc.
specifications, if not injury may occur and/or damage to unit.
Do not touch any rotating pump or motor components: injury may
occur.
Do not run pump dry, unless designed for that service.
Running dry is harmful to the pump, and will cause excessive heating
due to internal friction.
Check pump rotation and inlet/outlet pump port orientation before
connecting power to pump. If not injury may occur.
When pulling out cords from outlets do not pull cord, grasp plug to
prevent plug damage or electrical shock.
Fluid Metering, Inc. Drive Motors become HOT and can cause
a burn
.
DO NOT TOUCH!
Turn off the electrical power before checking pump for any problems.
Connect motor, speed controllers, or any other electrical devices
based on Fluid Metering Inc. specifications. Any unauthorized work
performed on the product by the purchaser or by third parties can
impair product functionality and thereby relieves Fluid Metering, Inc.
of all warranty claims or liability for any misuse that will cause
damage to product and/or injury to the individual.
Power cables and leads should not be bent, pulled or inserted by
excessive force. Otherwise there is a threat of electrical shock or fire.
Replace any inline fuses only with fuse rating as specified by Fluid
Metering, Inc.
When pump/drive is under operation, never point discharge tubing
into face or touch any rotating components of pump.
In a power down thermal overload cut-in condition, unplug or turn off
power to pump. Always allow a cool down period before restarting:
otherwise, injury or damage may occur.
For 30 seconds after power is removed from pump/drive: do not
touch any output terminals. Electrical shock may occur because of
residual voltage.

2.0 GENERAL SET-UP
2.1 Setting Dispense Stroke Rate
Strokes Per Minute (spm): For fluids of 500cps
viscosity or less a stroke rate of 120-350 spm max is
ideal. For fluids with greater than 500cps a slower rate
is recommended.
2.2 Fluidics:
Inlet (Suction) Tubing:
To avoid cavitation use the
most resilient tubing possible with the largest
inside diameter (I.D.)
Outlet (Dispense) Tubing:
For best dispense
performance use rigid Teflon tubing (to reduce
peristaltic action) with an equal or smaller I.D. than the
inlet (suction) tubing.
REQUIRED TOOLS:
1.Analytical Pan Balance
2.Hex Key Driver for Adjusting Stroke Length:
STH: 3/32" Hex Driver
STQ: 7/32" Hex Driver
3.A removable wicking thread lock (loctite 290)
1.0 PUMP MOUNTING: For optimum pump per-
formance it is recommended that your FMI pump
be mounted in a vertical position
with the pump
head down in a 6:00 o'clock position and the motor
at 12:00 o'clock.This orientation will allow air bub-
bles that enter the pumping chamber to directly exit
through buoyancy assistance.
