GRX-4000 Series Control Units and Wallstations
Clean front surface of control with a soft towel moistened with a mild
soap solution (non-ammonia- based). Clean approximately every six
months.
Caution!
Do not spray cleaning solution onto control as
it may reach internal components.
GP Panels
1.
Clean any dirt from air vent openings with a vacuum and check
for any obstructions which may block air flow. Keep 12" (30.5 cm)
above and below panels unobstructed.
2.
If any extra wiring is brought into the power panel, thoroughly
remove all metal chips, wire strands, insulation and other debris
before reapplying power.
3.
In the unlikely event of damage to dimming equipment, turn off
breakers, replace bypass jumpers and turn on breakers. This will
apply full power to fixtures.
Fluorescent Fixtures
1.
It is important that lamps are maintained properly to prevent
what may appear as dimming equipment malfunctions. When
lamps begin to fail on a circuit, Lutron recommends group
relamping of the entire circuit.
2. New fluorescent lamps must be “seasoned” for
dimming applications by operating at full intensity for
their first 100 hours.
Leave the lamps at full intensity for 100 hours. Although this
may be inconvenient, it is necessary for good dimming
performance, and achieving normal lamp life.
Warning!
For proper dimming performance fluorescent
lamps must be operated at full intensity for 100 hours
prior to dimming.
Why keep the lamps at full intensity for 100 hours?
Lamp that was
NOT
seasoned for 100 hours.
Lamp that
WAS
seasoned for 100 hours.
New fluorescent lamps have impurities in them which lamp manufacturers cannot eliminate completely. Lamps must be operated at full
intensity for 100 hours
before dimming
to neutralize the harmful effects of these impurities. Without the 100 hours at full intensity, the
impurities may cause the lamp to fail within a week (or failure may take months depending on usage and the amount of impurities).
