7. Now the control panel assembly is free.
CAUTION FOR TOUCH CONTROL PANEL REMOVAL
1) Hold the lower end (Position A, Fig. 1) of the touch
control panel assembly firmly while sliding it down and
toward you.
2) If the Touch Control Panel is hard to remove;
(1) Insert a flat head screw driver into space B . (Fig. 1)
(2) Rotate the screwdriver clockwise while holding posi-
tion C of the Touch Control Panel. (Fig. 2)
TO AVOID DAMAGE TO TOUCH CONTROL PANEL,
COVER THE TIP OF SCREWDRIVER WITH TAPE.
Installation
1. Insert the receptacle into terminal insulator.
2. Close covers of the terminal insulator, as shown
illustlated below.
CONTROL PANEL ASSEMBLY AND CONTROL UNIT REMOVAL
Replacement of individual component is as follows:
CONTROL UNIT AND CONTROL PANEL FRAME
(WITH SWITCH UNIT)
8. Remove three (3) screws holding the control panel
mounting angle to the panel frame.
9. Lift up the control panel mounting angle from the
panel frame.
10.Disconnect the connectors (G) and (E) from the
control unit.
11.Remove four (4) screws holding the control unit to
the panel frame assembly.
12.Now, the control unit and control panel frame (with
switch unit) are free.
CAUTION:
At installing control panel unit assembly to main
body set:
1. Ensure the installation of wiring-related parts
without negligence.
2. When inserting wire cable to main body set,
ensure them free from caught-in trouble. In
addition, when installing the control panel
assembly to base plate with screws, be sure of
pushing the control panel unit upward to fix with
