a circuit test lamp or connect it directly to the line voltage terminals LI and
L2 on the EQSO board. (Page 9-2, Figure 13) l£ the solenoid fails to operate
on line voltage, check wiring circuit.
1. To replace
a. Turn power and gas off.
b. Disconnect leads from terminal board and remove from valve and
controls enclosure.
c. Remove screws holding solenoid to valve body.
d. Install new solenoid per manufacturer's instructions provided
with kit. Reverse removal procedures.
PRESSURE f^GULATQR:
The gas pressure regulator is an integral part of the
gas valve. It is normally set at 4 inches of water column at the factory.
It can be adjusted by removing the cap from the post, and inserting a screw
driver. Clockwise rotation will raise the pressure and vice/versa. It
should not be adjusted to less than 3 inches nor above 4 1 / 2 inches of water
column. A common U tube manometer or pressure gauge (P/N 122804 should be used
when making adjustments. Remove the plug on the side of the valve body and
attach the manometer tube equipped with a 1/8 NPT tube fitting).
GLO MR BURNER ASSETIELY:
The burner should need no attention during the life
of the dryer, if the dryer is converted to L.P. gas, the main burner orifices
must be changed. See table for proper orifice sizes.
1. To replace main burner orifices
a. Turn power and gas off.
b. Remove screws molding gas valve and manifold assembly to
burner box.
c. Unscrew (4) burner orifices.
d. Replace by reversing the procedure.
ELECTRIC HEATING ELFENTS:
Eighteen heating elements consisting of twelve
3000 watt and six 4000 watt output develop 60 kilowatts at 208/240 volts or
416/480 volts. They are rack mounted in five adjacent bays with three or four
elements in each bay to provide a near even distribution of heat to the tumbler.
The elements can be individually replaced. Defective elements should be re­
placed only with an element of identical voltage and wattage rating. (Page 9-16,
Figure 12)
1. To replace
a. Turn power off.
b. Remove screws from terminal housing cover and remove cover.
c. Remove electrical connecting hardware and insulation from
screw terminals of element.
d. Remove access cover screws and remove cover,
e. Withdraw element from side rail supports.
f. Replace element and reverse the procedure.
