B. ADJUSTMENTS
7 DAYS AFTER INSTALLATION and EVERY 6 MONTHS THEREAFTER
Inspect bolts, nuts, screws (bearing set screws), nonpermanent gas connections (i.e., unions, shut-off valves,
orifices), and grounding connections. Fan (impellor) V-belts, along with the drive motor V-belts should be
examined and replaced if necessary. Tighten loose V-belts when necessary. Complete operational check of
controls and valves. Complete operational check of ALL safety devices (i.e., door switches, lint drawer switch,
sail switch, burner and hi-limit thermostats).
30 DAYS AFTER INSTALLATION
SHUT OFF ALL POWER TO THE DRYER. Verify that the electrical connections to the motor contactors
and overloads are tight. This is done to accommodate the compression of the wires over time.
