 The AC442 must always be transported in its operating
position. Never lay the AC442 on its side, as oil could
then escape from the vacuum pump or the built in
compres
sor could be damaged. There are no additional
safety systems for protecting the
AC442 against
damage resulting from natural catastrophes.
 We recommend calibrating the scales at least once per
year.
Contact customer service for calibration of the scales.
 The AC442 must be subjected to regular maintenance by
service personnel or authorized agents to ensure the safety
of the unit.

 For safety reasons it is advisable to use a residual current
operated circuit breaker (rccb) with the following
specifications:
Parameters

except for maintenance or repair purposes.
 Avoid using an extension cord with the unit. If
necessary, use a good condition (three wire grounded,
#14AWG or larger) extension cord of the shortest
possible length. In addition, the current drawn by all
devices connected to the wall socket must not exceed
15A total.
