D-9 PRESSURE REGULATOR MAINTENANCE
a. Pressure Adjustments
Pressure regulator (50, Figure D-6) is fac-
tory set to 20 psi (138 kPa). Should the
pressure need to be changed or adjusted,
use the knob on top of the pressure
regulator.
b. Condensation Drain
To drain excess moisture from the internal
gas circuit of the MPS, periodically loosen
drain valve (46) on the bottom of pressure
regulator (50). The moisture will flow
through vinyl tubing drain (47) on the bottom
of pressure regulator (50) and exit the bot-
tom of MPS enclosure (1).
