SAFETY PRECAUTIONS
Your photographic equipment is powered by mains electricity,
and is designed to comply with international electrical safety
standards. However, basic safety precautions must always be
followed when operating electrical equipment, including the
following, where applicable:
Read and understand all instructions and equipment labels.
Close supervision is necessary when the equipment is being used
by inexperienced personnel.
Take care to avoid burns. Some internal parts of the equipment
can become very hot with continuous use.
Do not operate equipment that has been dropped or damaged,
or has damaged electrical leads. Have the equipment examined
by qualified personnel.
Do not allow any electrical lead to touch hot surfaces.
Ensure the leads are arranged such that they cannot be pulled or
tripped over.
Ensure extension leads are of a suitable current rating to prevent
the lead overheating.
Always unplug or isolate the equipment when it is not in use.
Never pull plugs out by holding the lead.
For equipment connected to the electrical mains supply by a plug
and socket arrangement, ensure the socket is installed near to the
equipment and is easily accessible at all times.
Do not touch electrical components with wet or damp hands.
Ensure the air flow through the vents is not obstructed when
equipment is switched on.
Do not dismantle the equipment unless you are qualified to do
so. Incorrect assembly can cause hazards both to yourself and to
the equipment.
All equipment, no matter how well made, can break down and,
therefore, must not be left unattended for long periods of time
while it is switched on.
Always unplug or isolate the equipment before connecting or
disconnecting any plugs supplying electrical power to or from the
equipment.
Always obey local codes of practice, particularly for installation
requirements.
Do not destroy these instructions

INTRODUCTION

See figure 1.1.
The ILFOLAB 1250RC variable speed dryer is designed to dry
ILFORD black and white resin coated papers to a very high
standard. The dryer will dry up to 380 20.3x25.4cm
(8x10 inches) prints per hour, and has a maximum feed width of
50.8cm (20 inches).
For uniform drying and greater efficiency, prints are dried by
infra-red, fan assisted heaters. The print transport speed is
variable for precise control of a wide range of drying conditions
and materials.
This manual gives full instructions for installing and operating the
ILFOLAB 1250RC dryer. For ease of description, it is assumed
the left and right hand sides of the dryer are determined when
facing the dryer at the paper feed (front) end.

See figure 2.1.
‘POWER’ LIGHT
The red ‘POWER’light illuminates when the dryer control is
selected to ‘I ‘or ‘RUNDOWN’.
‘READY’LIGHT
The orange ‘READY’light indicates that the machine has warmed
up and is ready for use.
DRYER CONTROL
The dryer control has three positions:
Position ‘O’
The dryer is switched off.
Position ‘RUNDOWN’
In this position the power supply to the heaters is switched off,
but the fans and main drive continue to run. After a pre-set time
(factory set), the fans and main drive are switched off
automatically.
Note
It is recommended that this position is used before switching the
dryer off at the end of the day. Select this position to remove
moist air from the dryer and to prevent excessive heat retention
in the rollers.
Position ‘I ‘
For drying sheets. See section 8 for speed range.
SPEED CONTROL
The speed control adjusts the time taken for sheets to pass
through the dryer and, therefore, the rate of drying. The speed
control operates when the dryer control is selected to ‘I ‘and is
adjustable over the range minimum setting (slowest) to maximum
setting (quickest).
