Section 2: Service Guidelines
2.5.5 Other Components
In a normal operating environment check, clean and treat the components listed below every 6 months or so to
help ensure proper lamp and projector function.
Lamp Blower
NOTICE! DO NOT bend the impeller blades or loosen the balancing weights.
A clogged lamp blower impeller or motor can reduce air flow leading to possible overheating and lamp failure
of the lamp. Ensure loose dirt is vacuumed from the lamp blower impeller.
Igniter
Clean the high voltage terminal and insulator to remove accumulated dust or dirt.
Airflow Interlocks
The CP2230 uses two airflow interlocks; a lamp blower vane switch and an extractor vane switch. The lamp
blower vane switch is located within the lamp cooling compartment. The extractor vane switch is located just
inside the top duct on the projector lid. Check and clean the switches to remove accumulated dust or dirt that
could impede movement if necessary. Within the exhaust duct connected at the top of the projector, adequate
airflow must be maintained and routed outside of the building. Inspect regularly and confirm that 1) there are
no obstructions or “kinks” within the ducting, 2) all air intake areas are unobstructed, and 3) exhaust airflow is
at least 450 CFM* for 2kw and 3kW lamps and 600 CFM* for the 4.5kW and 6KW lamps (measured at the
rigid end of the duct when not connected to the projector).
Laminar Airflow Device (LAD)
Check: Every 6 months
The LAD filter is located in the light engine compartment. It is secured to the light engine assembly handle.
The LAD filter should be nearly white in color. If it appears a dark gray color (rare) it will require replacement
by a Christie authorized service technician. Contact Christie or your dealer.
