INSTALLATION

1. General safety precautions

Ceﬂa Sc - Ceﬂa Dental Group guarantees the safety, reliability and performance of the equipment under the following

conditions:

• Installation and technical service is performed by authorized technicians using Ceﬂa Sc - Ceﬂa Dental Group original

spare parts.

• The electrical system in the dental surgery corresponds to standards I.E.C. 60364-7-710;V2 (Standards regarding

electrical systems in a medical environment) or equivalent standards currently in force in the country where the equi-

pment is installed.

• The place where the x-ray unit is installed must comply with ofﬁcial directives regulating radiation in the country where

the equipment is used.

• The equipment is operated as directed in the instructions manual..

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device

may not cause harmful interference, and (2) this device must accept any interference received, including interference

that may cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of

the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential

installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in

accordance with the instructions, may cause harmful interference to radio communications

Changes or modiﬁcations not expressly approved by the party responsible for compliance could void the user’s autho-

rity to operate the equipment.

INSTALLATION

3. Before installation

3.1. Mechanical speciﬁcations required

If the wall is thin (hollow bricks or similar), use the backplate (part no. 99930887) to be mounted on the wall or placed

on the side of the wall opposite the wall where the unit is to be installed.

Decide on a suitable system for ﬁxing the plate according to the characteristics of the wall and its ability to resist a pull

force of 220 Kg applied at each anchorage point.

If the wall is made of cement or solid bricks, use the wall plugs supplied.

Alternatively we recommend using the “FISHER” chemical wall plugs which include:

• Braid type injection insert (item FIP 16X85).

• Threaded bar with bar and washer (item FIP 16M, 8X110).

• Chemical ﬁxer (item FIP C 150).

3.2. Central control unit power supply

The supply line running to the central control unit must be 3x2.5 mm and protected by a bipolar circuit breaker which

conforms to the relevant electrical codes (10 A, 250 V, breaking power at least 6000 A, distance between contacts at

least 3 mm).

The colour of the three conductors (LINE, NEUTRAL and GROUND) must correspond to that established by regula-

tions.

3.3. Wiring connection between central control unit and generator light

This connection enables the generator light (optional) located outside the surgery to be turned on.

To connect the LP generator light to the central control unit, use 2 conductors having a cross-section of 0.5 mm (see

paragraph 4.8.).

LP light supply: 230V - 3x2.5 mm line.

4. Installation

The x-ray unit must be installed by a qualiﬁed technician in compliance with the installation instructions given below as

regards both the mechanical and electrical parts.

WARNING!

Always check that the voltage indicated on the generator’s nameplate corresponds to that for the electrical

system.

Figure POSITIONING

4.2. Wall-mounted plate for supporting the x-ray unit

Figure A

Determine the position of the x-ray unit by using the INSTALLATION JIG.•

• Position the wall-mount plate with the bottom holes at a height of approx. 120 cm from the ﬂoor.

• First check that the plate is at the correct height and perfectly horizontal and then mark out the four points where it is

to be ﬁxed on the wall. Drill the holes and install the most suitable type of fastening system according to the characte-

ristics of the wall (see paragraph 3.1).

• Pass the supply cable through one of the holes in the wall-mount plate and ﬁx this to the wall by partially tightening

the top and bottom screws.

4.1. Positioning the x-ray unit’s structure

Figure POSITIONING

Block the middle clamp in the opening provided (d) accor-• ding to which of the three positions available the structure

needs to be placed in:

A – PRESET CONFIGURATION WITH WALL-MOUNTED

STRUCTURE SET HORIZONTALLY TO THE RIGHT.

B - WALL-MOUNTED STRUCTURE SET VERTICALLY

DOWNWARD.

C - WALL-MOUNTED STRUCTURE SET HORIZONTALLY

TO THE LEFT.

• Secure the pin to the plate using the srews (f) and washers

(e) provided.

INSTALLATION

4.3. Extension arm

WARNING!

Do not lubricate the pin of the extension arm: the wall-mounted plate is provided with self-lubricating bushings.

Figure B

• Insert the pin (b) of the extension arm (c) in the hole provided in the wall-mounted plate.

• Take the clutch (a) from the kit, install it on the plate using the corresponding screws and adjust the arm (c) as requi-

red.

Figure C

• Use a spirit level to check that the arm (c) is slightly tilted upwards (approx. 1°). If necessary add a shim to the plate

near the bottom wall plugs (d).

• Fully secure the plate.

Figure D

• If the x-ray unit is installed in one of the corners of the dental surgery, make sure the extension arm cannot rotate too

far (90°) by installing the two end-stop pins (included in the kit) on the x-ray unit itself.

• Find the right position for installing the pair of pins (a, b) and insert them in the holes provided using a hammer.

4.4. Installing the double pantograph arm

WARNING!

The arms are supplied secured together by a belt.

This belt should not be removed until the two free ends of the arms have been connected to their corresponding

attachments: the extension arm (already secured to the wall) and x-ray head.

If the belt is loosened before ﬁxing the arms in place, releasing them abruptly could damage them and the

operator risks being injured.

Figure E

• Take the washer (f) from the kit and position it at point (i) corresponding to the extension arm (c).

• Pass the cable (m) of the pantograph arm (e) through the extension arm (c) so that it comes out of the hole below.

• Install the pantograph arm (e) on the extension arm (c)

NOTE:

The extension arm’s bushing is self-lubricating.

Do not lubricate the pin of the double-pantograph arm.

• Pass the cable (m) through the inside of the extension arm (c) so that it comes out of the wall-mounted plate.

• Install the plugs (g) in the corresponding holes in the extension arm (c). Figure E

Figure F

Take the grubscrew used to stop rotation (o) from the x-ray unit kit and tighten it at point H (tighten it fully and then• loosen by ½ turn).

NOTE:Turn the pantograph arm to check that the adjustment has been made properly.

Take the clutch assembly (friction element, screw and 4 curved washers) from the x-ray unit kit and install it at point• L. NOTE: Insert the curved washers (j) and the friction element (k) as indicated in ﬁgure F.
