A preventive maintenance program will insure high reliability and long life for the transfer
switch. The preventive maintenance program for the transfer switch should include the
following items:
Inspection and Cleaning
Before doing any work on the transfer switch, de-energize all sources of power. The switch
should be inspected for any accumulation of dust, dirt, or moisture, and should be cleaned
by vacuuming or wiping with a dry cloth or soft brush.
DO NOT
use a blower since debris
may become lodged in the electrical and mechanical components and cause damage.
Remove the transfer switch barriers or arch chutes and check the condition of the contacts.
Any surface deposits must be removed with a clean cloth (
DO NOT USE EMERY CLOTH OR A
FILE
). If the contacts are worn excessively, they should be replaced. A general inspection of
mechanical integrity should be made to include loose, broken or badly worn parts.
Servicing
All worn or inoperative parts must be replaced using Zenith recommended replacement
parts. Appendix B at the back of this manual includes replacement part information for
typical power and control panel configurations. When ordering parts provide the model
number or serial number from the transfer switch rating nameplate.
Please refer to the Replacement Parts manual for specific part information and ordering
procedures. Please contact the Zenith Technical Services Department for the Replacement
Parts manual.
The operating mechanism of the transfer switch is lubricated with Lubriplate 105. The
lubricant applied at the factory provides adequate lubrication for the lifetime of the switch.
Should debris contaminate the mechanism, clean and apply additional Lubriplate.
Zenith can provide complete preventative maintenance services. Please contact the Zenith
Technical Services Department for additional information.
