Preventive Maintenance
Philips recommends basic preventive maintenance that is intended to minimize
the possibility of unexpected failure. Most recommendations rely on thorough
cleaning.
Preventive maintenance of the system consists primarily of periodically and con-
sistently cleaning the air filter and maintaining the cart.
Thorough cleaning is particularly important for pieces of peripheral equipment
because they contain electromechanical devices. If exposed to constant and
excessive environmental dust and humidity, these devices will suffer in both per-
formance and reliability.
Recommended Frequency of Maintenance Procedures
The frequency of system preventive maintenance plays a key role in extending or
eliminating downtime due to poor performance or unexpected breakdown.
Table 5-1 offers recommendations, but you can make necessary adjustments
based on factors such as the frequency of usage and environmental conditions. In
all cases, Philips recommends that you frequently check safety-related items.
