Chiller Ramp Upgrade Procedure

What is Affected

The New Chiller Ramp was cut in on production systems P0681 and above.
Installation of the New Chiller Ramp also requires installation of the Black Exhaust Shaft and Fan [903862].

The Black Exhaust Shaft and Fan [903862] should NOT be installed on P281 and below.

The Black Exhaust Shaft and Fan [903862] has a shield in place to keep air from flowing up from the Chiller Heat Sink and toward the linear distributor.
Without that shield, the Chiller Ramp's Peltier heat is routed back into the Panther rather than the rear vent.
On systems in warm environments (Lab Temps  ≥ 26 ˚C  (warm but still in spec),  Hot Peltiers, can report Chiller Seebeck voltage of range errors (High).

Note— The upgraded Chiller Ramp can be installed on ALL Systems P0281 or greater. If a System is P0281 and lower, the upgraded Chiller Ramp can ONLY be installed if there is no vacuum housing present.

Parts and Materials Required

• Proper PPE

• 3mm Allen wrench
• CHILLER RAMP, MODULE

Time Required

Procedure

Warning—If replacing a NEW Chiller Ramp [903734], the Black Exhaust Shaft and Fan [903862] MUST be installed. If a Silver Exhaust Vent [903402] is installed, replace with a Black Exhaust Shaft and Fan [903862]

1. Put on proper PPE.
2. Shutdown the Panther System and PC.
3. Open the Universal Fluids Drawer.
4. Open the right-side Panther system door.
