"#$%&'()
This manual contains servicing and repair instructions and product information for the Poseidon Xstream regulator series. The
different Xstream regulator models are most clearly identifed by their color. There is always a possibility that the customer has
altered the colors himself, why it is important always to check the permanently marked article number as part of the identification
of the product. The pictures below show where to find the article and serial number:

Poseidon has made several improvements, all introduced 2003 starting with serial number 310001.
Starting in 2006, all Xstream 1st stages are equipped with an adjustment screw cover. Older versions with no adjustment screws
should be upgraded.
Startingin2009,allXstream90modelrststagesareequippedwithabuiltinoverpressurevalve.
Starting 2015-01-01, all Xstream Deep 1st stages/regulators are Nitrox ready out of the box.

Product upgrades
Regulators with serial numbers less than 310001 are subject to a mandatory update programme. To obtain updated replacement
parts, order the kit 4826 and submit to Poseidon the serial number of the regulator by sending an email to service@poseidon.
com with the serialnumber and date of service clearly marked.
Regulators fulfilling this criteria shall have the following parts replaced on its first service:
• 4560 replaced by 4760 Seat holder. Seats on regulators numbered after 310001 are
different and will not fit older seat holders.
• 4577replacedby4777Lowerpin-guide.Theparthasbeenchangedtowithstanda
greater torque.
• 4562replacedby4762Uppercentrepiece.Theparthasbeenchangedtocorrespond
to the change of 4577
• 4581Washer.Theparthasbeenchangedtoeaseassemblythroughamoreprecisefit.
• 0015-012(4423)O-ring
• 4563Pin bushing 1.stage Xstream
Information about Xstream Upgrade kit 4826
4760 Seat holder and 4581 Washer are not critical parts to replace, however old seat holders will not fit new seats and is therefore
includedintheUpdatekitXstreamataspecialprice.4777Lowerpin-guideand4762Uppercentrepieceshouldbereplaced
and is therefore included in the kit at no cost.
Information about Xstream 1st stage covers.
During 2006, we began manufacturing Xstream DEEP, DEEP90, DURATION, DURATION90 and DECO 1st stages with chrome
colored 1st stage covers with an adjustment screw. Starting january 2007, all Xstream 1st stages, regardless of model/version,
will have a chrome colored 1st stage cover with an adjustment screw.
Information about Xstream Upgrade to cover with adjustment screw.
Any Xstream 1st stages that don’t have a cover with an adjustment screw should be upgraded with a cover that has an
adjustment screw. This upgrade is not mandatory but recommended.
The upgrade is made using the ”Xstream Adjustable kit” (4767-KIT) that contains the following parts:
• 1x4767-CEXstreamcover
• 1x4798-CHAdjustmentscrew
• 1x4763Adjustmentspring
• 1x4764Seatspring
All these parts must be replaced when upgrading the 1st stage!
Recommendations
For regulators with serial numbers less than 310001 we recommend to offer the customer to replace the old type valve housing
nuttotheimprovedversionwitharticlenumber4547.Thiswillsignificantlyreducetheinhalationeffort.Howeverifthecustomer
choses to keep his old valve housing nut it is perfectly safe to do so.
EN 144-3
Xstream Deco, Xstream Duration and Xstream Duration90 are available also in EN 144-3 configurations, i.e., regulators which
comply with the new EN 144-3 standard. See page 3 for correct article numbers.
Older Xstream models can be upgraded to comply with the same standard using an EN 144-3 upgrade kit. See Spare Parts lists
on page 13 for details.
Article number on o-rings
In this revision of the service manual, all o-ring article number have been updated to match the current article number system
used by Poseidon. A conversion list between the old and new o-ring article numbers can be found on page 14.
Nitrox ready (EAN40)
Xstream Deep regulators with serial number 1500001 and later are Nitrox ready from the manufacturer. A special EAN40 ser-
vice kit for the Xstream Deep 1st stage (article number 0009-016) and a EAN40 service kit for the Xstream Deep / Jetstream
2nd stage (article number 0009-017) has been introduced.

TobecoveredbythePoseidonLifetimeWarrantyprogram,allXstreamregulatorsmustbeservicedatleastonceevery24
months.
It’s recommended that the Xstream regulator is service once every 24 months or once every 100 dives, which ever comes
first.
The serviced regulator must also be registered on the Poseidon website (http://extranet.poseidon.com).
It is always acceptable to do a service or cleaning up, on customers request.
It’srecommendedthatlowpressurehosesarereplacedonceeveryfour(4)yearstoavoidLPhosefailuiresduetowearand
tare.
If water has entered a first stage (or suspiciion there of), the first stage shoudl be disassembled, cleaned and dried before
diving with it again. Water inside a 1st stage can cause corrosion or damage that has a negative effect on the functionality of
the 1st stage.
Xstream Deep 1st stages and regulators with serialnumber 1500001 or higher comes Nitrox Ready out of the box. To maintain
this status, the EAN40 service kits must be used and only oxygen compatible lubricants applied. Testing and adjusting must
be made using gas filtered in accordance with the EAN standard.
Xstream Deep 90 1st stages and regulators with serial numbers lower than 1500001 can be serviced to reach Nitrox Ready
level if the following actions are taken:
• All 1st stage components made out of metal are washed in an ultra sonic cleaner, using the Poseidon Fine clean Ultra
liquid, for a time period of 10 - 15 minutes.
• The EAN40 service kits (0009-016 and 0009-017) are used for the 1st and 2nd stage.
• Only Poseidon oxygen compatible lubricant (part number 8515) is used
• Gas filtered according to the EAN standard is used for testing/adjusting.
