Помогите с переводом! field charging в контексте
Service Connections
and Serviceability.
Two Schrader service ports are
provided in every unit. The suction
side and discharge side ports are for
FIELD CHARGING and servicing access. All
valves are 7/16 in. SAE connections. All
water and electrical connections are
made from the front of the unit. Unit is
designed for front access serviceability.

Если, например, вода внутри, тогда о каком заряде речь идет..

charging еще и наполнение, заливка, заправка, так что все нормально.
