S-76 C++ question

[bb in ca]

This question is about the overhead switch panel on S-76 C++ aircraft.

We have an unused switch position identified as "LIQ HTRS".

What system is controlled by this switch?

Just a guess, but might that be the windshield washer fluid heater switch? Ours don't have that particular switch, but something in my foggy memory seems to recall there being a heater for the washer fluid.

On VIP aircraft this is the master switch for the tea & coffee heaters in the Refreshment Cabinet.

Tres important ....
