Edition 3 April 2012 Mars/Mars Pro Service Manual
Page 15/59
The electric frame is installed in the same way with the exception that the side panels house the electric motors for raising /
lowering the cabinet.
On the rear of the frame is positioned the motor connection box from which the power cable is taken. The power cable
must be connected to a suitable mains voltage power source.
3.3 Media valves (Gas / Vacuum )
The Mars cabinet is designed to accept the fitting of media connections through the
side windows. Both side windows are, as standard, provided with one hole of Ø
23mm for the fitting of such connections. If more media connections are required
then the window can be replaced with one having 3 holes (see Fig 2 item 9).
The media valves are colour coded in accordance with international standards so it is
important to install the correct valve for the purpose required. If flammable gas is required
in the cabinet then the gas line must also be fitted with an electric solenoid valve, which
will cut off the gas supply in the event of a power failure. (Part No 9,000,020,030). This
will be fitted to the inlet pipe on the outside of the cabinet and wired back to
the main control board as detailed in part 3.3.1.

Item No 10 Spare light tube
Two light tubes are installed in each Mars cabinet above the laminator sheet. To access the light tubes, the laminator sheet
must first be removed. (See fig 3 below)
To access the laminator sheet it is first necessary to raise the motorized window to the highest position allowing a fully
open work area.
1. Pull the 2 ribbons on the laminator towards the front of the
cabinet
to compress the sprung brackets (see (A) below in Fig 5) and
then
downwards to the base of the cabinet. This will allow the
laminator
and frame to drop down. Take care to avoid it dropping
completely
and causing damage.
2. Remove the laminator from the cabinet and place in a secure place
to avoid inadvertent damage. Fig. 3.
3. The fluorescent light tubes can then be seen along the top front and
rear of the cabinet work area. (See Fig 4)
4. Ensure the power is turned off and rotate the tube through 90º so
5. the tube is free of the connections and carefully remove it from the Fig 3 Removal of cabinet. Laminator
6. Repeat the procedure with the other tube if both are to be replaced.
7. Insert a new tube in the reverse procedure.
8. Replace the laminator by positioning it carefully towards the front of the cabinet and then raising into position at
the back, locating it securely above the flanges around the edge of the work zone.

Item N o 11 Spare UV tube
The UV germicidal tube (when fitted) is located on a platform on the inside front wall of the cabinet above the work area.
It is fitted by means of a locking device and relevant ring nuts. The light is emitted at a wavelength of 254nm, which
produces deactivation of proteins and nucleic acid strands, thus sterilizing the work area. Since UV irradiation is harmful
to skin, the operator and the environment around the cabinet must be protected from accidental exposure, and therefore the
UV light is only functional when the window is fully closed. (To set up UV exposure times see relevant section under
“Controller settings”)
The average life time under normal operation is expected to be around 3000 working hours but since the UV
effectiveness reduces with time it is recommended that the UV tube be replaced annually if used regularly (daily) or at a
running time of no more than 2000 hours.
To replace the UV lamp proceed as described below:
1Raise the motorized front window to the full open position to allow access to the work area.
2Rotate the ring nuts anticlockwise until they unhook, release them from the tube as shown in Figure 7
3Rotate the germicidal tube 90º to release it from it’s seating.
4Release the ring nuts from the germicidal lamp and transfer them to the new lamp.
5Fit the new lamp by following the procedure in reverse order.
Under certain circumstances, it may be necessary to replace the Lamp starter as well. The starter can be found on the side
of the platform. To replace it, simply rotate it anti-clockwise until it loosens, release it, replace with a new starter and
rotate clockwise until secure.
