Red Lion C48C - Manual (Page 10)

Mounting Instructions
1. Prepare the panel cutout to the dimensions shown in Figure 3, Multiple Unit
Stacking.
2. Remove the panel latch from the unit. Discard the cardboard sleeve.
3. Carefully remove the center section of the panel gasket and discard. Slide the
panel gasket over the unit from the rear, seating it against the lip at the front
of the case.
4. Insert the unit into the panel cutout. While holding the unit in place, push the
panel latch over the rear of the unit, engaging the tabs of the panel latch in
the farthest forward slot possible.
5. To achieve a proper seal, tighten the panel latch screws evenly until the unit
is snug in the panel, torquing the screws to approximately 7 in-lbs.
Overtightening can result in distortion of the panel, and reduce the
effectiveness of the seal.
Note: The installation location of the counter is important. Be sure to keep it
away from heat sources (ovens, furnaces, etc.), and away from direct contact
with caustic vapors, oils, steam, or any other process by-products in which
exposure may affect proper operation.
Caution: Disconnect power to the unit and to the output control
circuits to eliminate the potential shock hazard when removing the
entire unit or unit assembly.
Unit Removal Procedure
To remove the entire unit with case from the panel, first loosen the panel latch
screws. Insert flat blade screwdrivers between the panel latch and the case on
either side of the unit, so that the latches disengage from the grooves in the case.
Push the unit through the panel from the rear.
Removing Unit Assembly
The unit assembly, shown in Figure 4, must be removed from the case to
change DIP switch settings or to replace the relay output board. To remove the
unit assembly, insert a flat blade screwdriver into the pry slot on either side of
the unit. Twist the screwdriver handle until the unit is ejected enough to allow
removal.
Caution: The unit assembly contains electronic circuits that can be damaged by
static electricity. Before removing the assembly, discharge static charge on
your body by touching an earth ground point. It is also important that the unit
assembly be handled only by the bezel. Additionally, if it is necessary to
handle a circuit board, be certain that hands are free from dirt, oil, etc., to
avoid circuit contamination that may lead to malfunction. If it becomes
necessary to ship the unit for repairs, place the unit in its case before
shipping it.
Installing Unit Assembly
To install the unit assembly, insert the assembly into the case until the bezel
is fully seated against the lip of the case. Properly installing the unit assembly
is necessary for watertight front panel sealing.
