1. Introduction Omega Series
750 Press
The Omega Series 750 Press is a pneumatically operated heat press for
transfer printing and material fusing. It is ideal for high volume
production with low operator fatigue.
The work area of the Omega Series 750 Press is 80 cm x 100 cm (31.5
in x 39 in) but machines may have, to special order, optional smaller
sized interchangeable worktables of any size and various shapes within
this table size.
The Omega Series 750 Press has a worktable which pulls out towards
the operating position and away from the heat plate for loading and
unloading. After loading the work piece, and with the correct settings
for temperature, pressure and dwell time, the worktable is pushed back
to the operating position with the handle provided. The cycle is started
by pressing the green buttons on either the side of the head. The
controller operates the timer and the solenoid valve and thus the
pneumatic cylinder. When the set time elapses the heat plate is
automatically lifted, enabling the worktable to be pulled out. The
worktable may then be unloaded and reloaded ready for another cycle.
The Omega Series 750 Press is produced in one version, nominally
230 Volts AC for the European market.

interlock.
1.4 Safety Tips
If required, our customer service team can arrange maintenance
service.
 The Omega Series 750 Press meets the European Legislation
standard. Under normal conditions accidents are rare.
However, listed below are some practical points to ensure your
safety.
 Always switch off and isolate the mains supply (i.e.
Remove plug) before undertaking any maintenance work
or cleaning the machine, or when not in use.
 Keep other people away from the machine during use.
 Ensure that there is sufficient space around the machine.
Cables and connections must not get jammed. Although
the heat radiation of the press is low, there should be
enough space for cooling down.
 Avoid contact with the press element.
 DO NOT REMOVE THE TOP COVER UNLESS
QUALIFIED TO DO SO - touching internal parts is
dangerous and may cause shock hazard.
 PROTECT THE MAINS CABLE - damage to the mains cable
may cause fire or shock hazard. When unplugging, hold by the
plug only and remove carefully. Take care that the mains cable
does not come into contact with the heat plate (or moving parts of
the mechanism) during operation of the machine.
 FOR SAFETY REASONS - please ensure that when the machine
is not in use the table is fully closed.
OPERATING AMBIENT TEMPERATURE RANGE – the
operating ambient temperature range is 0oC –35oC, (32oF -
104oF) and humidity of 20 - 80%.

Safety Tips (cont.)
 MACHINE FUSES - type: ultra-rapid (FF) fuses 1¼”. (230
Vac Max. 27 Amps)
 WARNING - THIS APPARATUS MUST BE
EARTHED (GROUNDED).
 CAUTION
This machine gets hot whilst operating. Take care not to touch
any surfaces that are labelled “Caution this plate is HOT”.
 MACHINE OPERATION
Only suitably trained personnel should operate this
machine.
This machine is designed to be operated by one operator
only.
 CAUTION
Please ensure the table is fully engaged before pressing the
green cycle start buttons.
For operator safety this machine is fitted with a non-return
valve that prevents the table from lowering if the air supply is
lost.
Contact your print media suppliers to ascertain whether fumes
are given off during the process, and if so what precautions are
needed for operator safety. These may include air extraction
and/or masks for personnel.

2 Installation
2.1 Transport instructions
The machine comes to you, in a shipping crate, and is held in place
with bolts, for safe transportation. If you have to transport the machine
at any time it is recommended that you use a similar box and packing
method. Please let the machine cool down fully before attempting to
pack.
2.2 Installing the machine
Take the machine out of the crate, due to the weight of the machine
we recommend that a fork lift truck or winch is used. Put the machine
on a sturdy worktable close to a suitable electric socket and compressed
air supply connection point, within easy reach of the operator. There
must be sufficient space for the machine’s table to be pulled out until it
hits the built in stops and back to the pressing position without creating
trapping points against adjacent articles. Ensure that no items vulnerable
to heat radiation are too close to the machine.
2.3 Electrical requirements
The Omega Series 750 Press should be connected to the mains supply
(nominally 230 Volts AC for the European Market) using either a
commando plug and socket or an isolator box.
The press is designed for 230 Volts AC 50/60 hertz and requires
exclusive use of a power outlet rated for at least 32 amps.
Ensure that the supply rating on the machine specification plate
corresponds with your local supply and that the correct plug is fitted.
MAINS LEAD
The wires in this mains lead are coloured in accordance with the
following code:
Green and Yellow: EARTH
230 VAC Blue: NEUTRAL
Brown: LIVE
Wiring the plug for a 230 VAC machine.
As the colours of the wires in the mains lead of this apparatus may not
correspond with the coloured markings identifying the terminals in your
plug, proceed as follows:-
1. The wire, which is, coloured green and yellow must be

Page 7
Electrical requirements (cont.)
connected to the terminal in the plug, which is marked by the
letter E, or by the safety earth symbol coloured green, or green
and yellow.
2. The wire coloured blue must be connected to the terminal,
which is marked with the letter N, (Neutral connector)
3. The wire coloured brown must be connected to the terminal,
which is marked with the letter L, (Live connector)
NOTE: Replacement of the mains cable must be undertaken by a
competent service engineer.
2.4 Pneumatic requirements
The Omega Series 750 Press should be connected through a filter
regulator to a compressed air supply capable of delivering 30 litres/min
at a pressure of 3.5 - 5 bar. max. (1.06 cu.ft./min at 14.5 - 72.5 Psi).
The press will not operate if the pressure drops below 1 bar. (14.5 Psi)
Double hose clips should be used on the delivery hose.
We would advise that when setting up the machine you check that
sufficient pressure is maintained into the regulator valve. When the
desired pressure is achieved the regulator is locked by pushing the knob
back down. We recommend that this should be set between 3.5 to 5 bar.
The Pressure Adjustment Gauge on the left hand side of the machine
should only be used to control the settings required for heat transfer and
garments.
2.5 Adjusting the pressure
This press is fitted with a manually adjustable pneumatic pressure
regulator on the left hand side of the machine. To adjust the operating
air pressure, and therefore the pressure exerted by the press on the work,
the regulator is unlocked by pulling upwards on the black plastic knob.
Turning the regulator knob clockwise will increase the air pressure;
turning anticlockwise will decrease the pressure. When the desired
pressure is achieved the regulator is locked by pushing the knob back
down.

3. How to Operate the Omega
Series 750 Press
3.1 Starting with the Omega Series 750 Press
3.1.1 Turn on the Omega Series 750 Press; the on/off switch is
on the front of the machine head. Set the machine controls as
necessary. See instructions for adjusting the pressure, section
2.5, and the operation of the time temperature unit, section 5.2.
When the set temperature is steady in the display the machine
is ready to use.
3.2 Working with Heat Transfer Materials
3.2.1 Ascertain from the supplier of the transfer paper and/or the
suppliers of the material, that the material to be used is suitable
and has been prepared for transfer printing.
3.2.2 Obtain from the supplier of the transfer paper, or material to
be used, the recommended temperature, time and pressure
settings for the material to be worked on.
Approximate settings are usually within the following:-
180oC - 200oC (350oF - 400oF) Heat Setting
10 - 30 sec Time Dwell Setting
3.2.3 Wait until the set temperature has been reached, signalled by
the temperature on the controller display becoming steady at
the desired figure. Pull the table assembly from beneath the
heat plate using the handle on the front of the machine. Place
the work piece on the pressure pad, removing all wrinkles.
Place the transfer in the desired position. Push the table
assembly back into the pressing position, until it stops. This
will ‘trigger’ the micro switch which will enable the machine
to perform a heat transfer cycle.
3.2.4 Start the sequence by pressing the green buttons located on
either side of the machine head. The heat plate will
automatically lower to the table. (The process can be stopped
at any time by using the “EMERGENCY STOP” button on the
front of the machine head. This will automatically raise the
heat plate away from the table).
CAUTION
Please ensure the table is fully engaged before pressing the
green cycle start buttons.
3.2.5 At the end of the set time, the heat plate rises, allowing the
table to be pulled out to permit unloading.

Page 9
3.3 Pressing Pad Assembly
The pressing pad supplied with this machine is made of heat proof
foam/green silicone and has a Nomex® cover and although they are
extremely durable they must be maintained in good condition at all
times and replaced when showing signs of wear. A worn pressing pad
will always affect the quality of printing/fusing.
CAUTION: Do not insert items into the machine, which would tend to
cut the pressing pad, i.e. buttons, pins, press-studs or zips.
IMPORTANT NOTE:
The pressing pad supplied with the machine is of the correct thickness.
Using a thicker pad may invalidate your warranty.
3.4 Shutting Down
To shut down the machine when a cycle is finished, turn off the red
illuminated rocker switch on the front of the machine head.
To temporarily interrupt the pressing cycle, press the red button on
the front of the machine head.
3.5 Fault Diagnosis
This Omega Series 750 Press has built in fault diagnosis. The display
may show the following:
1. Probe Fault
If the probe goes open circuit, the display will show “Probe
Fault” immediately. Contact your machine supplier
immediately.
3. “CAL” Fault
If “CAL” appears in the controller display the controller will
need to be recalibrated. Switch off the machine and contact
your supplier for an instruction sheet.
CAUTION
In all fault conditions switch off the power to the machine and
unplug the machine from the electrical supply before
contacting your machine supplier.

3.6 Hints and Tips
Transfer Printing
Extra care should always be taken to ensure that transfer paper is
placed print down onto the article, as mistakes will result in the heat
plate becoming soiled with ink and spoiling following work.
When transfer printing, it may be found advantageous to cover the
press pad with paper or P.T.F.E. to prevent strike-through of surplus
ink, particularly when printing thin material as surplus print on the
pressing pad cover can also strike back on the following work.
Transfer Paper/Motifs Fail to Print Out Correctly
Check:-
1. Heat and time dwell settings are correct.
2. Article having transfers applied is locked in contact between
pressing pad and heat plate.
3. Pressing pad is in good condition, is flat and making complete
contact over the whole area of the heat plate. See Pressing Pad
details.
“Ghosting” (Double Image) of Transfer Prints
Check:-
1. Material being used has been correctly heat set for transfer
printing.
2. Material being used does not shrink during printing process,
i.e. measure material before and after printing.
3. Transfer paper does not move after printing process upon lift
off of the heat plate.
4. If possible, use adhesive coated paper, particularly to
overcome fabric shrinkage.
5. By pre-shrinking of material in press before transfer printing.

Page 11
4. Maintenance of the Machine
4.1 Daily Maintenance
For good press results it is important to keep the press surfaces clean.
Wipe the surface of the heat plate with a dry non-abrasive cloth before
use when the plate is cold.
When heat plates are hot and not in use, keep in the open position away
from the foam pad.
4.2 Periodic Maintenance
Periodically clean the TEFLON® coated heat plate with a non-abrasive
piece of cloth. Stubborn stains may be cleaned, when heat plate is cool,
with mineral spirits.
4.3 Cleaning
First unplug the machine. Clean the outside of the machine frequently
with a clean, moist cloth. This may conveniently be carried out when
the machine is cold.
To prevent soiling of the substrate, periodic wiping of the entire exterior
of the machine, including heat plate, with a clean rag is recommended.
If necessary, use mineral spirits for cleaning a cold machine. Since
mineral spirits are flammable, use precautions at all times and keep
away from sparks, flames or hot heat plate.
