SCHEDULED SERVICE

It is recommended that the Apeks XTX second stage regulator
should be serviced annually regardless of usage.
However, If at all unsure about the correct functioning of the
Apeks XTX, then it must be officially 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.
XTX Second Stage Regulator Maintenance Manual
An Official 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 for opening effort that is within the
acceptable range.
4. Checking for smooth operation of the control knob
and venturi switch.
5. A visual inspection of any filters for debris or dis-
colouration.
6. A visual inspection of the exhaust valve(s) to see
that they are in good condition and that it is seating
against a clean and undamaged surface.
7. A visual inspection of the mouthpiece looking for
tears or holes and checking the general condition.
8. Pulling back hose protectors and checking that the
hoses are secure in the hose crimps.
If a regulator fails steps 1,2,3 or 4 the entire regulator
should be serviced. If a regulator fails 5,6 or 7 it will be up
to the technician's discretion whether or not a full service
is required. Failure of step 8 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 specifically set up and equipped for the task.
Adequate lighting, cleanliness, and easy access to all
required tools are essential for an efficient 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 fittings 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 2nd
stage service kit (AP0219). 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 specification 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.
