Installation, Operation, and Maintenance
VWR Zero Air Generator
Catalyst Bed
The catalyst bed should be replaced if contamination occurs due to the presence
of lead, phosphorous, sulfur, silicates or halocarbons in the source air. If your
instrumentation begins to show signs of unpurified air, this may indicate a
contaminated catalyst bed. Replacement should be performed by qualified
service personnel only. Contact Parker Hannifin Corporation technical service to
order a replacement catalyst tower. (For 110V: Model 26000-020 P/N 75394
and Model 26000-022 P/N BO1-0020. For 220V units: Model 26000-020 P/N
75394-220 and Model 26000-022 P/N B01-0020-220).
Precautions
High temperature components are found inside the cabinet, and should not
require any user service. The temperature of the gas at the outlet port may reach
as high as 45°C (113°F).
The tubing and fittings connecting the generator to other sources and
instruments are under pressure. Be sure to relieve any pressure from the system
before loosening or removing any fittings or tubing.
