Disconnect the input power before servicing. The replacement of the Halogen
lamp can be done by the removal of the rear panel, or by sliding the transparent
shutter front panel and then removing the access cover from the deck (Figures 5-
19 & 5-20).
Release the lamp assembly by gently sliding downwards. Loosen the front screws
❷ in the socket ❸ and remove the burnt out lamp ❹.
Insert a new halogen lamp fully into the socket and firmly tighten the screws to
secure the lamp. It is recommended to slightly press both of the lamps retaining
spring clips ❶ before fitting the lamp. Slide the lamp assembly onto the light cone
and orient the lamp socket in the vertical position as shown in the Figure 5-20.
5-4.3. REPLACEMENT OF HYDRAULIC TUBES
There are three tubing and accessory kits for maintenance. A Bimonthly
Maintenance Kit for ISE tubing, Six Month Kit for special tubes exposed to wear
and tear, including pump cartridges, etc., and an annual maintenance kit for
general tubing for interconnections and liquid transfers.
When installing any tubing kit, it is important that the hydraulic circuit is empty. To
avoid any undesired liquid spills, disconnect the external water input before
applying any maintenance kit. Turn on the instrument and perform a washing
cycle to evacuate all liquid in the hydraulic circuit. When changing tubes, follow
the illustrative diagrams (Figure 5-21) on the next page.
