5.
A pre-regulator filter prevents debris from contaminating the regulator. Filter element is 50
micron.
6. High pressure TESCOM regulator(s) reduce pressure of incoming air from high-pressure bottles
to a level required by diver’s Hat/Helmet. To increase the diver’s air pressure, turn knob
clockwise to desired setting. To decrease the diver’s air pressure, turn knob counter clock-wise.
Note: Regulator is a non-venting type, in order to reduce the set pressure, air must be flowing through
the regulator.
B. Low Pressure
The Low Pressure Section consists of a LP input, low pressure output of regulator, LP gauge, and diver
connection. A small portion of the LP air is also used when diver depth measurements are made.
Accepts breathing air from a low-pressure source i.e. a low pressure diving air compressor. Note: The
low-pressure section does not regulate the air pressure to the diver. The compressor must be set to
provide the proper pressure to the diver.
Breathing air from the low-pressure side of the regulator or the low-pressure input is routed to the diver’s
breathing air connections. A portion of the low-pressure air is used by the pneumo section for diver depth
measurements.
1. Low pressure input, #6 JIC type fitting. (O
2
type fitting available).
2.
Low-pressure check valve prevents the back flow of air from the HP regulator
output into the LP air source. This also permits simple switch over from LP to HP
air.
3. 1/4 Turn ball valve, controls flow of air to diver, ball valve permits unrestricted flow.
4. Divers air supply gauge reads air pressure to divers, 0-400 PSI.
5. Divers air supply outlet connection, O
2
(oxygen) type fitting. (37
o
JIC optional).
6. Pressure relief valve, factory set for 285 PSI, vents excess pressure to
atmosphere. Vent is located between diver output connections.
