6. TUBE INSTALLATION (Fig. 7)
When installing a new tube, turn the Main power switch OFF.
(Fig. 11-2)
A. The tube should be installed in the vertical position with the
anode end down. Insert the tube inside strap (A) and with
the fittings (B) facing right, tighten strap (A) around the
tube body.
B. Connect the longer water hose from the water choke to the
top fitting of the tube anode; the shorter water hose to the
bottom fitting
C. Connect the white wire (C) from the flange of the tube to
the resistors above.
D. Using bolts and washers fasten securely to terminal
connector (D)
a. Connect the white wire of the tube to the center terminal screw.
b. Connect the black wires from the tube to the outer terminal screws.
NOTE:
Arrange leads with ample space between them so they do not touch
one another and tighten nuts securely.
NEW TUBE BREAK IN
New tubes should be operated for 30 minutes with only the filament ON. Do not operate the machine for that
period of time. After the 30 minutes have elapsed, the unit can be used in Normal operation. This procedure
should be performed only for the first operation of the tube and is not necessary every time the unit is turned
on. If the unit was inoperative for a period of two months or more, the above procedure should be followed.
7. WATER & ELECTRICAL CALIBRATION
Read INSTRUMENTS AND CONTROLS DESCRIPTION for reference:
A. Turn on main water valve and check for leaks on interior and exterior connections.
Check water flow from outlet hose of drain.
B. Turn the main POWER switch to the ON position. (Fig. 11-2)
C. Adjust the water pressure regulator to 20 psi. The temperature controller will illuminate if the following
conditions are met: The unit is receiving water, fuses (F1 & F2) are not blown, and circuit breaker
(Fig. 11-1) is in the ON position.
D. Transformer tap selection
a. With a voltmeter, measure the voltage at the fuse box on the wall.
b. Follow the table below and connect wire # 7 to the appropriate voltage tap at the control
transformer (Fig - 8)
