The following guide is intended to be used if a problem occurs during
the use of the SS1-R side wall vent system. At several steps
throughout the guide you will be required to measure 115 Volts with
a voltmeter, (See Diagram T).
Extreme caution must be exercised to prevent injury. If you are
unable to determine the defective part with the use of this guide, call
your Tjernlund distributor or Tjernlund Products direct at 1-800-255-
4208 for further assistance.
Step 1.
Verify that 115V is present between "L1" and "L2"
on terminal strip, (See Diagram T).
