WARNING:Ensure
that the hose nut screws
up until it stops. Do not
over tighten with tools as this
will not prevent
leakage in unlikely event of
damage.
(3) The nut will ratchet on the
locking slide ring as the nut is
screwed in, producing an audible
clicking sound. This system pre-
vents the hose from unscrewing
and coming free. Approximately
3 turns are all that are needed
to tighten, which will produce
approximately 16-18 clicks of
the ratchet.
WARNING: DO NOT connect medium pressure hoses (inflator
hoses and second stage hoses) to high pressure (HP) ports. This
will cause medium pressure hoses to burst when pressurised,
which can result in serious injury. High pressure ports are identified by
the letters ‘HP’ on your regulator and are mainly used for instrumentation
and air integrated computers.
1. Remove the port blanking plug
from your first stage regulator
using a 5mm Allen key.
NOTE: Care must be taken when
using a spanner/wrench when
tightening the hose connections. The
spanner can score and damage the chrome
plating finish of the first stage body around
the port area.
Hose fitting operation for All First Stages.
WARNING:If a 2nd
stage is not being used,
ALWAYS ensure a medium
pressure relief valve is tted.
(Apeks part No:AP0721).
2.Ensure the O-Ring is present
and in good condition on the hose
to be fitted. Screw the threaded
end of the hose into the port,
making sure that the thread is
screwed in square to the port.
Tighten to 46Nm (40Lbs/in)using
an appropriate spanner.
WARNING: The
regulator needs to
be tted with at least
one high pressure indicator or
gauge which displays the supply
pressure.
Important: 1st stage
NOTE: Medium pressure ports
(MP) use a 3/8” UNF thread in
accordance with EN250. High pressure
ports (HP) use a 7/16” UNF thread.
Depending on the model of first stage the
number of HP and MP ports may vary.
