SIDEBLOCK ASSEMBLY (120B)
The low pressure inflator system may be used
with either conventional buoyancy compensators
or dry suit systems. For certain pieces of equip-

hose than is originally supplied by the manufac-
turer of the low pressure system. The low pres-
sure inflator port is not available on "A" masks.
Tools Required:
5/32 inch Allen Wrench Attachment on Torque
Wrench
1) Remove the l.p. plug (115) from the side block
assembly (120b).

2) Check the O-ring on the low pressure whip to
be sure it is present and in good condition. Care-
fully screw the low pressure whip into the side
block.
3) Tighten fitting to the specifications provided
by the dry suit manufacturer. Do not overtighten.
4) Pressurize mask and test connection for leaks.

port on the side block for attachment of a low
pressure hose, a hose with built in flow restriction
or the KMDSI Flow Restrictor Adapter, KMDSI
P/N 555-210 must be used.
