Fig. 1
The MM90 STANDBY manifold covered by these instructions is designed to be used as a third
source of supply in medical central gas systems. The manifold will deliver gas when the nominal
supply system pressure falls below a set level. This is a back up source.
The manifold consists of manifold pressure regulator A , inlet shut off valve B and purge valve
C. Pressure gauge D is fitted to the inlet side downstream of B. It shows the content pressure of
the cylinder bank. An extra gauge E is also fitted to outlet F to show the outlet pressure. Pres-
sure switch no. 1 is fitted to the inlet downstream of B to indicate empty cylinders . Pressure
switches fitted to the outlet F indicate high no. 2 ("H" marking) and low no. 3 ("L" marking) outlet
pressures. The pressure switches shall be connected to an alarm panel (Gasalarm C44 – see
chapter Accessories) or central monitoring system to give a visual and audible indication of the
condition of the manifold.
