Mechanical Installation
The NV4 validator can be supplied with either the Conventional Bezel or the Universal bezel. Refer to drawings
on pages 40 and 45 for more details.
Mounting Recommendation Details for the Conventional Bezel
In connection with the following instructions refer to Drawings GA105 for Fitting Details, GA106 for
approximate dimensions required to fit the Validator, and GA107 for Cleaning & Removing the Validator.
1. The validator can be fitted to surfaces from 1mm - 8mm thick with the components supplied. Firstly cut an
aperture 82mm Wide by 63mm High through the Mounting Plate.
2. Remove the “Bezel” (PM100 & PM101) from the Pre-Assembled Unit by pushing down the Large Red
Button on top of the Validator, and levering back and lifting off the main part of the Unit.
3. Remove star washers, nuts (4 off) and bezel washer (2 off) from “Bezel”. Place the “Bezel” (PM100 &
PM101) through the aperture from the front (Showing Face) of the machine.
4. Holding the “Bezel” in position place the “Bezel Washer “(MC105 - 2 off) over the “Bezel” studs as shown
in the centre view of drawing GA105. Place “Star Washer” (WS102) onto each of the remaining part of the
studs followed by the “Nut” (WS103). Tighten the nuts, being careful not to over tighten as this will start to
deform the “Bezel Washer”.
5. Hook the rest of the unit into position as in the right hand view drawing GA105. Carefully check that it is
secure and held firmly.
6. Connect the necessary Interfaces with Power turned off.
Mounting Recommendation Details for the Universal Bezel
In connection with the following instructions refer to Drawings GA127 and GA128 for Fitting Details, and
GA126 for approximate dimensions required to fit the Validator.
1. Remove star washers and nuts (2 off) to remove Escutcheon panel from validator.
2. Press on the button on the top of the validator to hinge the Bezel forward, then unhook. Fix the Bezel to the
mounting panel using 4 off No.4 self tapping screws. The panel cut-out is detailed in drawing GA127. If the
validator is being mounted using the universal Bezel only, fit the validator back onto the Bezel.
3. If the escutcheon plate is being used, remove star washers and nuts (2 off) to remove the two escutcheon
clamps. Fit the escutcheon plate to the front panel, then refit the clamps, and secure with star washers and
nuts. The panel cut-out is detailed in drawing GA128.
4. If the escutcheon plate is being fitted to a separate hinged door or fascia panel, only tighten the nuts so that
the clamps are lightly nipped. With the Bezel secured firmly in position, swing the door shut, allowing the
bezel the guide the escutcheon plate into alignment. Open the panel and secure the nuts tightly.
5. If the validator is being secured directly by the escutcheon plate, then secure the escutcheon nuts tightly. Use
the second pair of nuts and star washers to secure the Bezel to the two studs in the escutcheon plate. Then
resecure the validator to the Bezel.
