Safety precautions for the fusing-lamp emitter
● Disregard of the safety precautions or improper operation of the infrared emitter can lead to injuries
and mat
erial damage.
● The IR heating device should be operated only by specialists or trained personnel.
The operator of the system should compile specific instructions for personnel training.
● The safety and functional reliability of the IR heating device are guaranteed only if you are using
original acce
ssories and spare parts from HP.
● After an emitter break, a dangerous voltage may be exposed to contact by the heating spiral.
● The reflector side should not be cleaned.
Transport and handling of the fusing-lamp emitter
● Transport the IR emitter, in the packaging provided, to the place of installation.
CAUTION: If the IR emitter must be transported without its packaging, wear linen gloves.
F
ingerprints on the quartz tube will cause devitrification, which leads to radiation losses and
mechanical failure.
● Always carry the emitter with both hands. Carry it so that the cross-section faces up, to avoid
bending and breaking.
● Grip the emitter only by the ceramic edges, and not by the pinches. Do not touch the glass unless
y
ou are wearing gloves.
● Avoid any pressure on the flat base.
When installing IR emitters
● HP recommends that you wear protective goggles when installing or replacing emitters, to protect
y
ourself from broken glass that you may come into contact with.
● The safety and functional reliability of the IR heating device are guaranteed only when using original
acce
ssories and spare parts from HP.
● After an emitter break, a dangerous voltage may be exposed to contact by the heating spiral.
● The reflector side should not be cleaned.
After installation, the bottom glasses of the IR emitter must be cleaned of any soiling or perspiration.
