Replacing the Regeneration Heater
(W3200 - 5000)
1
Stop the dryer, disconnect and lockout the main power.
2
Locate the heater(s).
Open the side panels of the dryer locating the
heaters which are secured to the inlet of the desiccant wheel assem-
bly by hard piping, a heater tube manifold, brackets and clamps.
See
Installation section entitled, Checking the Dryer for Proper Air Flow,
Opening and Closing the Dryer Doors (W1600-5000).
3
Disconnect the main power leads at the junction box inside the frame
of the dryer.
In units with two heaters (W3200 and W5000), it may be
necessary to measure resistance across the power leads of each heater tube
to determine which heater needs to be replaced. In a good element, the
resistance across all three legs should be +/- 5% resistance variation when
measured leg-to-leg, and high resistance from each leg to ground. Readings
other than this indicate a defective heater.
4
Disconnect the high temperature switch cables at the quick
disconnects.
5
Loosen the pressure clamps at the top and bottom of the heater tube con-
nection and slide the clamp and its silicon gasket back and away from
the heater tube to remove the defective regeneration heater tube(s).
W3200-5000 model dryers lower heater clamp(s) are attached to a mani-
fold that is secured to the desiccant wheel assembly with a bracket,
loosen the clamp that secures the heater tube to the manifold to remove it
from the dryer.
