WARNINGS: (1) Only use genuine Domino replacement parts.
Any other parts may not meet the design or
working requirements and put personnel at risk.
(2) Opening the cabinet door while the extraction
system is in operation will stop the extraction
process (see procedure below).
(3) Full protective clothing must be worn when
changing bags, filters and pads. Use the filter
change kits provided with each filter.
(4) Dispose of used filters in the plastic bag
provided in the filter change kit according to
local regulations.
General Notes
These notes are particular to the DPX scheduled maintenance.
• Alarms (audible and visual): refer to the Fault Finding and Repair
section
• Instruction sheets are provided with each repair kit and not in this
manual
• The main filter and chemical filters are heavy, therefore care must be
taken when removing
• Always check the following for debris build-up when changing a filter:
(a) Extraction nozzle
(b) Flexible hose
(c) Air inlet
(d) Sense line (silicone tubing attached to the inside of the air inlet).
Recommended Routine Maintenance
Primary maintenance is filter replacement. The fume extractor control
system will indicate when this is necessary. Experience of local conditions
may be used to formulate a periodic replacement schedule.
