FSR & FST First Stage Maintenance Manual
(AP5825F Issue 8)
INTRODUCTION
This manual provides factory prescribed procedures for the
correct maintenance and repair of the Apeks FSR & FST rst
stage regulators. The model shown in this manual is the FSR,
although the FST differs in appearance, most components
are identical. It is not intended to be used as an instructional
manual for untrained personnel. The procedures outlined
within this manual are to be performed only by personnel
who have received factory authorised training through an
Apeks Service & Repair Seminar. If you do not completely
understand all of the procedures outlined in this manual,
contact Apeks to speak directly with a Technical Advisor
before proceeding any further.

SCHEDULED SERVICE
It is recommended that the Apeks FSR & FST rst stage
regulators should be examined annually regardless of usage.
A full serviced should be performed every two years.
However, If at all unsure about the correct functioning of
the Apeks rst stage, then it must be ofcially inspected
immediately.
All service and inspection details need to be documented
in the Regulator Service Record in the back of the Owner’s
Manual to keep the Limited Lifetime Warranty in effect.
An Ofcial Inspection consists of:
1. A pressurised immersion test of the entire unit to
check for air leakage.
2. Checking for stable medium pressure that is within
the acceptable range.
3. Checking that all parts are tightly fastened together
and that no parts are loose.
4. A visual inspection of the Environmental Diaphragm
looking for tears or holes and checking the general
condition.
5. A visual inspection of any lters for debris or dis-
colouration.
6. Pulling back hose protectors and checking that the
hoses are secure in the hose crimps.
If a regulator fails steps 1,2, or 3 the entire regulator should
be serviced. If a regulator fails 4 or 5 it will be up to the
technician’s discretion whether or not a full service is re-
quired. Failure of step 6 requires replacement of the Hose.
GENERAL GUIDELINES
1. In order to correctly perform the procedures outlined
in this manual, it is important to follow each step
exactly in the order given. Read over the entire
manual to become familiar with all procedures and
to learn which specialty tools and replacement parts
will be required before commencing disassembly.
Keep the manual open beside you for reference while
performing each procedure. Do not rely on memory.
2. All service and repair should be carried out in a work
area specically set up and equipped for the task.
Adequate lighting, cleanliness, and easy access to all
required tools are essential for an efcient repair facil-
ity.
3. During disassembly, reusable components should be
segregated and not allowed to intermix with non-
reusable parts or parts from other units. Delicate
parts, including inlet ttings and valve seats which
contain critical sealing surfaces, must be protected
and isolated from other parts to prevent damage
during the cleaning procedure.
4. Use only genuine Apeks parts provided in the 1st
stage service kit (AP0241). DO NOT attempt to
substitute an Apeks part with another manufacturer’s,
regardless of any similarity in shape or size.
5. Do not attempt to reuse mandatory replacement
parts under any circumstances, regardless of the
amount of use the product has received since it was
manufactured or last serviced.
6. When reassembling, it is important to follow every
torque specication prescribed in this manual,
using a calibrated torque wrench. Most parts are
made of either marine brass or plastic, and can be
permanently damaged by undue stress.
