Graymills Peristaltic OMI - Manual (Page 2)

WARNINGS/CAUTIONS
Read all of these SAFETY INSTRUCTIONS and those in the
manual BEFORE installing or using this equipment. Keep this
manual handy for reference/training.
SAFETY
You will find various types of safety information on the following
pages and on the labels attached to Graymills equipment. The fol-
lowing Safety Statements explain their meaning:
The Safety Alert Symbol means ATTENTION! BECOME ALERT!
YOUR SAFETY IS INVOLVED!
DANGER The DANGER Symbol means that failure to follow
this safety statement will result in serious personal injury or
death.
WARNING The WARNING Symbol means that failure to fol-
low this safety statement might result in serious personal injury
or death.
CAUTION The CAUTION Symbol means that failure to follow
this safety statement might result in personal injury or property
damage.
NOTE The NOTE Symbol means failure to follow these
instructions could cause damage to the equipment or cause it
to operate improperly.
CAUTION
Never work with equipment you feel may be unsafe. Contact
your Supervisor immediately if you feel a piece of equipment is
in an unsafe condition.
WARNING
● All electrical work must be done in accordance with all
National and Local Codes by qualified personnel.
● We strongly recommend all electrical installations include a
Ground Fault Interrupter (GFI).
● Never use any electrical components or wiring to lift or
move pump. Check cords, wires, and air lines. Replace any
that are damaged prior to use. FAILURE TO DO THIS
COULD RESULT IN SEVERE INJURY OR DEATH.
● Motor must be suitable for the environment in which it is
used: Graymills’ standard electric motor peristaltic pumps
ARE NOT EXPLOSION PROOF. DO NOT USE for solvent or
other potentially explosive or flammable environments. If
explosion proof operation is required, USE ONLY Graymills
AIR MOTOR or ELECTRIC EXPLOSION PROOF peristaltic
pump.
● All pumping systems must be properly grounded for the
environment in which they are used, including static
prevention.
CAUTION
● Before doing any maintenance work, disconnect electrical
power or air supply.
●
Do not attempt to repair electrical components. Direct all
electrical repair questions to the factory.
● The Air Motor model and the Explosion-Proof Peristaltic in
KE and KF voltages are suitable for Class 1, Group D
atmosphere only. PPL-CE-KH meets CE Flameproof
Standard EEx-d IIB, ATEX listed motor.
●
Peristaltic pump motors must be mounted horizontally to
maintain safe, efficient operation.
● Do not allow liquids to come in contact with the motor,
controller or any electrical components. This could result in
injury to the operator, or damage to the pump.
● Motor housing should be opened only by qualified service
personnel. Never open motor housing cover while the pump
is connected to any electrical or air lines.
● When replacing motor housing cover, ensure that no wires
are being pinched. Make sure no bare wires come in con-
tact with housing. Have potential safety defects serviced
immediately.
● Pump may be heavy, depending on model. When lifting any
part of this system, follow all lifting and safety instructions
recommended by your company. If in doubt, ask your
supervisor.
● If pump head or rotor assembly shows signs of ear or
cracking, replace immediately. Never operate pump without
front of pump head cover. Use caution around roller assem-
bly due to heat from friction associated with the rollers and
the flexing hose
●
Enclosed peristaltic pumps with cooling openings in the
base of the pump must have free flow of air in order to
operate. Do not place objects alongside the pump that
would block air flow from reaching these openings, and do
not place any material or obstruction underneath the pump.
NOTE
● Air motor models MUST have filtered, lubricated air to prevent
damage to motor. An air regulator is also recommended. Order
Graymills part number FRL-1.
● For proper air motor operation, supply air at a pressure of 60-
80 psig (4,1 - 5,5 bar). Size the supply to deliver a minimum of
20 scfm @ 60 psig (566 l/m @ 0°C, 1 atm. delivered at 4.1 bar).
Use a dedicated line. Sharing an air line with large air users,
such as the press, can result in erratic and slow pumping.
● Always use supplied muffler.
● The tube selected by Graymills for use in the standard and the
explosion-proof peristaltic pumps has a specific ID, OD, durom-
eter and solvent resistance. It has been chosen after careful
testing. Other tubing may not have the same specifications and
may damage the pump or give shorter life.
● On all peristaltic pumps (electric and air driven) allow the pump
to come to a complete stop before reversing direction.
Otherwise, motor, control board or gearbox failure may result.
● Never put a valve on the pump discharge or place it in a circuit
that will result in the pump discharge being blocked. Resultant
pressure could result in premature tubing failure.

60 Hertz

NOTE: The PPS-GAM requires a dedicated air line capable of
supplying 20 scfm of air. If the pump is supplied with less than 20
scfm, it may not deliver its rated maximum gallons per minute. Do
not use an air line that is used for the press or any other large air
user.

AIR LINE PIPE SIZE
Figures in the body of the Air Line Size Chart (see page 19) are
pipe sizes suggested for long runs to keep pressure loss to a rea-
sonable value. The pipe size shown, or larger, should be used ALL
the way back to the compressor. For example, 25 CFM requires
3/4" pipe for distances to 200 feet. For 200 feet and over, 1" pipe
should be used the ENTIRE distance. If CFM air flow is not known,
use the second column as a guide allowing 3 to 4 CFM air flow for
every 1HP of the compressor if the air flow is at a constant rate.
