Reinstallation
3) Reconnect the fan power connector.
Push the fan casing up until it locks into place.
6-1B SMOOTHING CAPACITORS
A large-capacity aluminum electrolytic capacitor is used for smoothing the DC in the
main circuit, and an aluminum electrolytic capacitor is also used for stabilizing the
control power in the control circuit. Their characteristics are adversely affected by
ripple current, etc. When the inverter is operated in an ordinary, air-conditioned
environment, change the capacitors about every 5 years. When 5 years have elapsed,
the capacitors will deteriorate more rapidly.
Check the capacitors at least every year (less than six months if their life will be
expired soon).
Check the following:
1.) Case (side faces and bottom face for expansion)
2.) Sealing plate (for remarkable warping and extreme cracks)
3.) Explosion-proof valve (for excessive valve expansion and operation)
4.) Appearance, external cracks, discoloration, leakage. When measured
capacitance of he capacitor has reduced below 85% of the rating, change the
capacitor.

Relays
To prevent a contact fault, etc., relays must be changed according to the number of accumulative switching
times (switching life is approximately 30,000 rides).
6-3 Projector Bulb
To prevent an excessive down time, due to the projector bulb burning out, obtain a spare bulb whenever the
INFOCUS run time states over 750 hours. We do not know at this time how long this bulb lasts. This is
only a suggestion for having on hand this spare part, not a requirement.
Note: Projector bulbs can be obtained from Infocus direct by ordering from a local distributor or going on
the internet to (
WWW.INFOCUS.COM ). Also the projector is warranted by Infocus direct by a pass
through warranty. Any maintenance done to the projector will void the warranty. Should you require a
loaner, Infocus will overnight delivery you a loaner for a fee if given a major credit card.
