SF350-17

SuperFlow® 350 Regulator 

Reassembly of the SuperFlow® 350 Demand Regulator

as needed so the port and starboard whiskers can 

be installed. 

For Older Double Exhaust Or Single Ex-

haust

18) For the older double exhaust or single ex-

haust, stretch the exhaust whisker onto the ex-

haust flange of the regulator. Fasten the double 

exhaust to the regulator with a tie wrap and 

tighten.

WARNING

The exhaust valves must be correctly 

installed in the exhaust valve inserts 

or they will not seal correctly. This 

could lead to a backflow of water into 

the helmet, which could expose the 

diver to contaminants in the water. 

Depending upon the properties of the 

contaminants, this could lead to seri-

ous personal injury or death.

For All Helmets

Inspect the whisker exhaust valve inserts for 

damage and contamination. Install new valves 

ensuring they are installed onto the correct side 

of the inserts.

19) Install the inserts with exhaust valves into 

the Quad-Valve main exhaust body. Refer to the 

notation or marks made when the parts were dis-

assembled.

B

 

WARNING

The exhaust valve inserts must be 

installed in the correct orientation in 

the Tri/Quad Valve exhaust main body. 

If the inserts are installed backwards, 

the diver will be unable to exhale. This 

could lead to suffocation and death.

For Helmets Equipped With Tie-Wraps

20) Install the left and right whiskers then in-

spect and install the tie-wraps.

For Helmets Equipped With Whisker 

Clamps

21) Install the left and right whiskers then in-

spect and install the whisker clamps. 

Place whisker clamps around the grooves on each 

of the two whiskers. Before doing the final tight-

ening of the whisker clamps, make sure that the 

parting line on the bottom of the wings is lined 

up with the parting line on the main body. For 

the SL 27 helmet ONLY, make sure that the 

parting line on the bottom of the whisker wings 

is 

5/16

" behind the parting line on the main body.

Note the step on the inside of the whisker 

clamps. These must be oriented in the correct 

position to retain the whisker properly.

Properly re-align the port and starboard wings to 

the main body.

For All Helmets

22) Pre install a tie wrap as shown onto the whis-

ker main body. This will make installation much 

easier and ensure a good seal.

Pre-install the tie wrap.
