Agilent Varian Optional Pump Ready 170ºF Thermal Switch for AX-65 Diffusion Pump. Agilent Varian Part Number L9964002 This is a (Optional) Pump Ready thermal switch. This thermal Pump Ready switch, is to be attached to the side plate of the AX-65 Pump next to the over temperature thermal switch. This optional thermal switch can be connected to a light to show when the pump is at operating temperature. It is normally open and closes when the pump reaches operating temperature. The switch is set to close at 170ºF (operating temperature). See graphic for installation/location on the pump.

Agilent Varian Replacement Over Temperature 365ºF Thermal Switch for AX-65 Diffusion Pump Heater Harnesses Agilent Varian Part Number L9964001 This is a 365ºF replacement thermal switch for the following AX-65 diffusion pump heater harnesses: 200W, 115 VAC heater harness, PN L9994307 250W, 115 VAC heater harness, PN L9994303 200W, 220 VAC heater harness, PN L9994308 250W, 220 VAC heater harness, PN L9994304 250W, 165 VAC heater harness, PN L9994302 250W, 90 VAC heater harness, PN L9994301 This is a replacement over temperature thermal switch. A normally-closed, over temperature thermal switch has been attached to the diffusion pump body via the heater harness on the side of the pump. Loss of cooling, high temperatures, high pressure, or low fluid level causes the contacts of the thermal switch to open. When the problem has been corrected, the thermal switch automatically resets to closed. The switch is set to open at 365ºF. See #6 on (diagram exploded view & parts) illustration below for location.
