The inlet valves (3) must normally be open, the handles set in a vertical position. The outlet valve (5)
should normally be open for the circuit in operation, the handle set in a vertical position. You can select
the operating side by opening one outlet valve and closing the other outlet valve. Set the desired alarm
limits on the alarm, see the hospital's and alarm unit's instructions.
Self-venting regulator:
The operating pressure is adjusted by
pulling
the knob on the pilot regulator outwards and turning it
clockwise to increase or counterclockwise to reduce the pressure. Read the pressure on the pilot
regulator's
pressure gauge
. Remember to adjust carefully, the pressure drops slowly about 0.5 bar / min.
Check the operating pressure against the outlet
pressure gauge
. When the adjustment is complete, lock
the adjustment knob by pressing it down again. NOTE! Never turn the regulator adjusting screw
(C)
.
Non-self-venting regulator
(reserve gas system only):
Increase the operating pressure by
pulling
the knob on the pilot regulator
outwards and turning it clockwise. Check against the pilot
regulator
pressure
gauge
and the outlet
pressure gauge
. Lower the operating pressure by carefully
opening the adjusting screw (C) on the regulator outlet side
until a low hissing
sound is heard.
Turn the control knob on the pilot
regulator
counterclockwise to
a lower pressure than operating pressure. Close adjusting screw (C) on the
outlet side of the regulator and then increase to the correct operating pressure
by turning the pilot
regulator
clockwise. Check against the pilot regulator's
pressure gauge
and the outlet
pressure gauge
that the correct operating
pressure has been reached. If the correct operating pressure is not reached,
repeat the procedure. When the adjustment is complete, lock the adjustment
knob on the pilot controller by pressing
it down
again. Do not touch the adjusting
screws marked A, B and D.
