XS Scuba MultiMax Breathable Inflator Service Manual
Maintenance Schedules
Breathable inflators, such as the MultiMax, are subjected
to a variety of environmental elements that over time can
affect their performance. Salt, sand, sediment, chlorine
and other chemicals all take their toll on a breathable
inflator. Soft parts wear out and lubricants break down
and wash away. As an XS Scuba Dealer, you are advised
to inform your staff and customers that the XS Scuba
MultiMax requires servicing at least once a year. Under
certain circumstances service is required every 3-6
months. Some of those circumstances are:
1. Frequent or improper use
2. Inadequate routine freshwater rinsing
3. Regulator use in dirty or polluted waters
4. Rental use
5. Regular use in chlorinated (pool) water
Recommended maintenance schedules are based on
average use under normal conditions and assume that
recommended preventative maintenance and storage
procedures have been followed as outlined in the
XS Scuba MultiMax Owner’s Manual.
Standard Procedures
1. Preview the list of tools and parts required to perform
the prescribed service outlined in this manual. Follow
each step in the sequence provided. Have this manual
open next to you for reference. Do not rely upon
memory.
2. Numbers found in parenthesis reference the KEY
numbers in the exploded diagrams. If you are not sure
what a part is by its description, use this number to
cross reference it in the exploded diagram.
3. All regulator services should be performed on a
workbench specifically set up and equipped for this
purpose. Adequate lighting and cleanliness along
with easy access to the required tools should be
considered mandatory.
4. Delicate parts, such as parts with critically machined
surfaces should be isolated from the other parts
to prevent damage, especially during the cleaning
procedure.
5. Only use factory authorized parts provided by
XS Scuba. Do not attempt to substitute other
manufacturer’s parts regardless of any similarity in
appearance. This is especially true for o-rings!
6. Do not attempt to reuse mandatory replacement
parts regardless of how much use those parts were
subjected to.
7. When reassembling, it is important to follow factory
mandated torque values using a calibrated torque
wrench. To do otherwise could lead to damage or
failure of the product.
8. Unless otherwise instructed, the following is
assumed:
a. When instructed to remove, unscrew or
loosen a threaded part, turn the part
counterclockwise. The manual abbreviates
counterclockwise with CCW.
b. When instructed to install, screw in or tighten
a threaded part, turn the part clockwise.
The manual abbreviates clockwise with CW.
9. The following abbreviations are used throughout this
manual:
a. HP = High Pressure – the pressure entering a
regulator from the cylinder e.g. 3000psi
b. MP = Medium Pressure – the pressure leaving
the first stage traveling to the 2nd stage. Also
referred to as intermediate or interstage pressure
c. LP = Low Pressure – the pressure exiting the
2nd stage through the mouthpiece. Also referred
to as ambient pressure.
Nitrox Compatibility
Since the MultiMax operates with a supply pressure
below 145 psi (10 bar), elevated percentages of oxygen
are not a concern with this product.
