This document is the instruction manual for the Purge Kit for TriScroll pumps. It describes the functionality and usage of the kit, as well as the applicable applications. The kit includes a flowmeter, manual throttle valve, 5 psig relief valve, tubing and fittings, and instructions.
This instruction manual provides guidance for using the TriScroll Purge Kit (P/N PTSPURGEKIT) with Agilent TriScroll 300 and 600 series pumps. The kit is designed to enable safe purging of either the main bearings or the pump exhaust region using regulated dry gas, typically Nitrogen at a recommended flow rate of 5 lpm.
The manual details installation procedures for two specific configurations: Bearing Purge and Gas Ballast purge. It includes steps for assembling the kit components (flowmeter, relief valve, tubing) and connecting them to the appropriate ports on the pump. Specific applications requiring these purges are listed, such as cryopump regeneration and leak detection with high helium rejection.
The recommended flow rate into either port is 5 lpm.
The purge gas pressure must be regulated to 5 psig or less.
The flowmeter must be positioned vertically to read accurately.
