PREPARATION AND SETUP
Hose Attachment
Apeks recommends that you take your regulator to your authorized
dealer for the installation of any accessory items, including
instrumentation, medium pressure (MP) quick disconnect hoses, and
alternative air source second stages. Your dealer can also answer any
questions you may have pertaining to the information in this manual. If
it is not possible to return your regulator and accessories to your
Apeks Authorized Dealer, you may install the accessories yourself
carefully performing the steps in the following procedure.
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
pressurized, 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 first stage body
around the port area.
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 46 kg/cm (40 lbs/in) using an
appropriate sized spanner.
