Maintenance and Repair
Introduction
The Vela CineCast Quad Pro decoder requires very little maintenance and should
require minimal repair during its useful lifetime. Power supply, fan, and fuse re-
placement, along with fan filter cleaning, are repair items covered in this chapter.
Any repairs mentioned in this chapter can be considered field repairs, negating the
need to ship the item away; however, any work done in the field should be per-
formed by qualified personnel.
Field Repair and Maintenance Overview
The CineCast Quad Pro is designed for field replacement of the fan, fan filters,
power supplies, and power line fuses. The Quad Pro also offers easy removal
(for cleaning) and reinstallation of the fan blower filter. Three access panels
located behind the front panel allow field replacement of the fan assembly, the
primary power supply and the secondary power supply. A sketch illustrating the
locations of these access panels is provided in Figure 4-1. Fuse replacement is
covered at the end of this chapter.
Fan Filter Maintenance
The Quad Pro decoder incorporates a fan filter that must be removed and cleaned
periodically to assure proper operation of the unit. The interval between cleanings
is dependent on the installation environment. The filter should be removed and
cleaned whenever it appears to be excessively dusty or dirty.
The filter is accessed by first removing the front cover. Front cover removal re-
quires no tools; it is removed by gripping and pulling on the plastic front cover.
The fan filter is then removed, cleaned and then returned to its original location.
See Figure 4-1 for its location.
Hazardous electrical voltages may be present in this equipment. Follow proper
safety procedures during installation and at any time the cabinet is open or
removed from the equipment rack. Remove all power from the unit before
connecting or disconnecting any external cables.
