The DPIs (Individual Protective Device) scrutinized in these operating instructions have
undergone every possible test for design validation by:

Germanisher Lloyd

Vorsetzen 35

20459 Hamburg—Germany

Notified Body n.: 0098

Full face Mask Neptune Space and SL35TX

comply with CE Certification in accordance with 89/689/EEC directives under the UNI
EN250:2000 standard rules for underwater activities , including cold water use.

PREMISE

The DPIs in question are a separate part of the self-contained underwater breathing
apparatus, commonly known as SCUBA.

They comply to European regulation EN-250:2000. They can be stored at a temperature
of between 32° and 140° F. It is necessary that this equipment only be used by fully
trained, certified divers.

Operating restrictions: The DPIs in question cannot be used with diving products
without the CE mark and the air supply must meet the requirements of EN 12021.
Incorrect use, non-original spare parts and insufficient or poor maintenance, besides
being dangerous to the health and life of the user, releases MESTEL Safety of any
responsibility and nullifies the warranty.

The series of DPIs described in the following manual are the following:

NEPTUNE SPACE with 1st stage SL 35TX: full face mask with integrated 2nd stage

regulator and SL 35 TX 1st stage.

WARNINGS, CAUTIONS, NOTES

Pay special attention to information provided in warnings, cautions, and notes, that is
accompanied by these symbols:

A WARNING indicates a procedure or situation that, if not avoided, could
result in serious injury or death to the user.

A CAUTION indicates any situation or technique that could cause damage to
the product, and could subsequently result in injury to the user.

A NOTE is used to emphasize important points, tips, and reminders.

NEPTUNE SPACE

INTRODUCTION

The Neptune SPACE mask was developed through
experience gained from producing products for military
personnel protection. All designs and materials were tested
to obtain superior performance and increased safety.

The high quality of the product does not allow
the user to ignore the problems connected
with the correct use of the product and the
rules for safe diving.

The SPACE mask is Nitrox compatible up to 40% of oxigen.

(NOT valid in the European Countries)

GENERAL PRECAUTIONS AND WARNINGS

Before using this mask, you must have successfully received training and
certification in the technique of SCUBA diving from a recognized certification agency
(or any U.S. Military or government operated diving school). Use of this equipment
by a person who is not certified by a recognized agency shall render all warranties,
express or implied, null and void.

Use of SCUBA equipment by uncertified or untrained persons is dangerous and
can result in serious injury or death.

This mask is not configured for commercial use with surface supplied air.
Always pressurize the Neptune Space RAPTOR gradually by opening the
cylinder valve SLOWLY.

NEVER lubricate any part of the Neptune Space or cylinder valve with any
lubricant. Lubrication must only be performed by an OCEAN REEF trained
technician.

DO NOT apply any type of aerosol spray on the Neptune Space. Doing so may
cause permanent damage to certain plastic components, including the second
stage housing.

DO NOT leave a cylinder standing unsecured with the Neptune Space
attached to the valve. Doing so may cause permanent damage to the Neptune
Space and cylinder valve if the cylinder falls over against the first stage.

Factory prescribed service for this product must be performed at least once
annually by a factory trained OCEAN REEF Service Technician who is
employed by an Authorized OCEAN REEF Dealer. Repair, service, disassembly,
or first stage adjustment must not be attempted by persons who are not

factory trained and authorized by OCEAN REEF.

Neptune Space is not CE certified to be used with NITROX!

The Neptune SPACE might be used with NITROX gasses up to 40% O2. It is
always recommended to use cleaned air from specified cleaned air
source. SL35TX 1st stage can’t be used with NITROX. Always use NITROX
compatible 1st stages when NITROX is required.

Note: not valid in the European Union.

When diving in cold water (below 450 F, or 70 C), you must have received
training and certification in the techniques of cold water diving from a
recognized training agency.

Before connecting the regulator to the tank, check the following:

• Check that the O-ring on the tank is in place on the valve and is in

perfect working condition (INT WITH Yoke nipple CGA 850 version
only). If it is damaged or missing, it should be replaced.

• Verify that the instrumentation and accessories have been installed

correctly.

WHAT’S THE CORRECT MASK SIZE?

The Neptune Space is available in two sizes, Small/Medium and Medium/Large.

In order to determine whether a diver should wear a S/M or M/L mask, OCEAN REEF has
designed a Mask Measuring Kit. The sizing and measuring system were designed in
accordance with the official measuring procedure used in the Los Alamos Scientific
Laboratory Charts at the SBCCOM Mask Fit Facility-Aberdeen Proving Ground (Maryland,

USA).

Before purchasing a mask, the customer may use the calliper to take two simple face
measurements. Using the Full Face Mask Size Recommendation Chart, he or she can
evaluate the size category into which the measurements fall. There are three different
size categories on the chart: Small/Medium, Both, & Medium/Large. If the
measurements fall within the both category, then the diver should technically be able to
wear either full face mask (M/L or S/M), and in that case should try on a mask to select
the best fit. Please note that the chart boundaries fade. The fading areas represent less
common face measurements. It is very likely that a mask will still fit comfortably even if
measurements are located in these fading areas.

USE OF CONVENTIONAL REGULATORS

A special adapter allows the connection of several kinds
of regulators. The adaptor is available in two sizes,
medium (standard) and small. This adapter fits in place
of the surface air valve (code 33020: S, code 33021: M).

USE OF OVER-INJECTED REGULATORS

Over injected regulators have a diaphragm with an
inhalation cracking pressure below zero. These
regulators “free flow” easily, and as a result, should not
be used with the Neptune Space or other Neptune masks.

Changes in regulator performance can also be caused by
the different positions assumed during a dive; the use of

a regulator with flow adjustment is recommended.

When descending the adjustment knob must always be turned on to get
the proper air flow. Do not turn off the adjustment knob while
descending.

1ST STAGE SL 35 TX

The Neptune Space may be used with this high performance, balanced diaphragm 1st

stage with anti-freeze kit. The first stage has adjustable medium pressure and is made

of brass with a satin finish body, stainless steel piston, Teflon seat, and stainless steel
spring.
It is available with the following characteristics:

• Standard connection 200 bar (code 9922)

• DIN connection 300 bar (code 9923)

• 2 high pressure ports 7/16 -20 UNF

• 4 Medium pressure ports 3/8-24 UNF

• Flow rate of approx. 4800 l/m at 140 bars
