1.3 Pre-dive check list
These guidelines are recommended by Ansell. Follow them for your safety and incorporate
them in your routine as a mandatory pre-dive check list.
1. Complete a dry suit diving course led by a certied instructor and maintain prociency by
regular dives.
2. Use a buoyancy compensator device for surface otation and for your safety. This is
optional when diving with surface supplied air.
3. Know your equipment and emergency procedures. Read the user manuals for all your
equipment.
4. Practice your dry suit diving skills under controlled conditions until they become second
nature.
5. Never dive alone. Dive with a buddy who has a thorough understanding of your dry suit
system. Do always have people on land or in a boat that are able to help you in case of
emergency.
6. Use the correct amount of insulation for the water conditions you are diving in and your
exercise rate.
7. Your weighting should allow you to make a decompression at 10 feet (3 meters) at the
completion of your dive with a tank containing 500 psi (30 bar) of air or less. Determine
the appropriate weight needed to attain neutral buoyancy by for example a pool dive.
Weight yourself at neutral buoyancy with an empty tank. An increased salinity in the
water requires more weight.
8. Check your valves, hose, zipper and seals before each dive.
9. Perform preventive maintenance and repairs on the suit regularly. At least once a year,
have the suit, valves and hose serviced by a qualied dealer service, but more frequently
if the suit is in heavy or extraordinary use.
10. Know your limitations and do not exceed them.
!!! DANGER !!!
Risk of injury due to reduced body functions when diving in cold water. Water or air
temperatures below 70 °F (21 °C) constitute cold water diving. Water or air temperatures
below 40 °F (5 °C) constitute ice diving. Ice diving is dangerous and requires special equipment,
training, preparations and procedures.
!! WARNING !!
Diving with a dry suit can be extremely dangerous. Do not attempt to use this dry suit without
prior training and certication by a qualied and certied instructor, and use of all necessary
and appropriate equipment.
!! WARNING !!
Risk of skin irritation and allergic reactions. The suit materials can cause skin irritation and
allergic reactions to individuals sensitive to these materials. Consult a medical professional if
in doubt.

4. Intended use
A dry suit protects its wearer by the exclusion of water and contaminants when underwater.
Latex seals are attached to the body of the suit at the neck and cuffs to prevent water from
entering whilst submerged.
Various types of underwear can be worn under the suit depending on water temperature,
depth and diver activity. The conservation of body heat using thermal protection in cold,
deep water is vitally important to the safety and efciency of divers, professional and
amateur alike.
The following chapters describe in detail how to use, maintain and carry out certain repairs
to your dry suit.
!!! DANGER !!!
Risk of injury due to reduced body functions when diving in cold water. Water or air
temperatures below 70 °F (21 °C) constitute cold water diving. Water or air temperatures
below 40 °F (5 °C) constitute ice diving. Ice diving is dangerous and requires special equipment,
training, preparations and procedures.
!! WARNING !!
Do not use other gas than air for ination of the suit. The use of oxygen enriched gas for
ination may cause re and explosion. The use of argon may cause the gas getting into the
face mask and breathing system through the hood. This has to be avoided because the effect
of breathing argon is more narcotic than nitrogen when under increased partial pressure.
!! WARNING !!
The suit itself does not have a depth limit, but all diving at great depths is potentially
dangerous and requires special training, skills and know-how.

5. Selecting and tting dry suit and underwear
5.1 Selecting and tting a dry suit
VIKING™ dry suits come in several different sizes that t a large percentage of divers. Since
a dry suit does not need to t snugly, each different size suit will t a range of body shapes
and sizes.
Even though the t of a dry suit is more forgiving than a wetsuit, the suit must t you
properly. If you are unable to squat or kneel easily in the dry suit while wearing an
insulating undergarment, the suit is too short.
A dry suit that is too long for your body can also be a problem. If the crotch of the suit
hangs more than 4 inches (10 cm) below your crotch when you are wearing it, the suit is
probably too long. Suits that are too long may allow air into the feet of the suit, causing
your boots and ns to pop off while diving. This is a dangerous situation.
When you try on a dry suit to determine your size, be sure to put on the bulkiest thermal
insulation you plan to use with the suit rst. After you have the suit on, check to see that
you can comfortably reach both the inator and exhaust valve when you have all your
equipment on.
5.1.1 VIKING™dry suit size charts
Size charts for each style of VIKING™ suit are available on the website at
http://protective.ansell.com. VIKING™ sizes are unisex.
5.2 Selecting and tting dry suit underwear
Dry suit underwear is designed specically for diving. Ordinary long underwear, or
sweatsuits, are not designed for diving, but may provide acceptable insulation for less
demanding diving conditions.
Each individual differs in the amount of insulation they need to wear. The amount of
insulation you need is determined by the following factors:
• Your body size and weight
• Your sex
• The water temperature when you dive
• Your exercise rate when diving

14
Always remember that each person has a different range of temperatures at which they
feel comfortable. What is comfortable to your instructor may not be comfortable for you or
your diving partner.
Just as too little insulation in cold water can make you quite uncomfortable, too much
insulation in warmer water can also make you uncomfortable. When topside conditions are
warm, it is essential to remove your dry suit between dives to allow your body to cool down.
Proper dry suit underwear must cover your arms, legs and torso. Separate socks or booties
must be worn to keep your feet warm and comfortable. Ansell offers a range of suitable
VIKING™ underwear.
!! WARNING !!
It is essential to adjust your insulation according to the environmental conditions where you
dive. Overheating is extremely dangerous. It can lead to exhaustion, blackout and in rare
instances, death.
!! WARNING !!
The type and amount of underwear used under your dry suit will affect your weight.
In most situations, the more insulation you wear, the more weight you will need to dive.
!! WARNING !!
Undergarment used in combination with a dry suit shall allow free passage of air between the
user’s body and the deation device.

15
6. Preparing for the dry suit dive
Before you use your dry suit for the rst time, the neck and wrist seals must be adjusted for
your individual use. The seals on all VIKING™ dry suits are made from latex or neoprene.
6.1 Adjusting latex neck seals
Latex is a exible rubber material, similar to that used in the manufacture of dishwashing
gloves. To make a watertight seal on your dry suit, latex seals are used at the wrists and
neck. The seals are manufactured in a cone shape and are trimmed to the size needed by
each dry suit owner.
If you are unfamiliar with trimming latex seals, Ansell recommends that you allow your
dealer to trim the seals on your suit for you. If you are an experienced dry suit user you may
want to trim the seals on your suit yourself.
Before you begin to trim your neck seal, measure the circumference of your neck at collar
level. This is the area where the seal will sit against your neck. Next, measure the opening
of the neck seal on your suit. When the neck seal is trimmed correctly, the opening will
usually be approximately 15-25 % smaller than the circumference of your neck. The neck
seal must stretch a bit when you wear it for it to work properly. If too much material is
removed the neck seal will leak.
1. To trim a latex neck seal, turn it inside out so that you can see the cutting guides
moulded into the seal. These guides are thin ridges that help you to trim the seal with an
even cut, helping to ensure a good seal.
2. Have your dive partner hold the seal so that it is attened. The ngers should grip the
seal approximately 1/4-1/2 inch (6-13 mm) back from the opening on either side. The
seal should be under slight tension. The two “edges” of the opening should be parallel to
each other.

16
3. Trim the seal with the largest,
sharpest scissors available, making
as few cuts as possible. Trim no
more than 1/4 inch (6 mm) of
material during a single cut. Try to
avoid leaving the edge of the seal
with a jagged surface that could
tear.
4. Try the neck seal on when you think you are cutting close to the right adjustment. To do
this, you don’t need to put the whole suit on; just spread the neck seal as explained in the
section Putting on your dry suit and pull it over your head. Adjust the seal so that it lies
at against your neck, as low as possible. It should be snug, but not uncomfortable.
New dry suit divers usually will feel that a snug neck seal is uncomfortable and doesn’t t
out of the water. However, after you have entered the water, you will nd that a snug neck
seal provides a good t and a proper seal.
!! WARNING !!
If your neck seal is too tight it can restrict the ow of blood to your brain, resulting in serious
injury or death.
6.2 Adjusting latex wrist seals
If you have large wrists you may nd that you need to trim the wrist seals on your dry suit,
too. The technique for trimming your wrist seals is similar to that used to trim your neck
seal.
Measure the circumference of your wrist above the wrist bone. The wrist seal will seal from
the wrist bone up your forearm another 1-1.5 inch (25-38 mm). Next, measure the opening
of the wrist seal on your suit. When the wrist seal is trimmed correctly, the opening will
usually be approximately 15-25 % smaller than the circumference of your wrist. The wrist
seal must stretch a bit when you wear if for it to work properly. If too much material is
removed the wrist seal will leak.

17
To trim a latex seal, have your dive partner hold the seal so that it is attened. The ngers
should grip the seal approximately 1/4-1/2 inch (6-13 mm) back from the opening on either
side. The seal should be under slight tension. The two “edges” of the opening should be
parallel to each other.
Trim the seal with the largest, sharpest scissors available, making as few cuts as possible.
Trim no more than one quarter inch of material during a single cut. Try to avoid leaving the
edge of the seal with a jagged surface that could tear.
! CAUTION !
If you damage the neck or wrist seals by trimming them excessively, replacement is NOT
covered by the VIKING™Warranty.
Try the wrist seal on when you think you are cutting close to the right adjustment. To do
this, you don’t need to put the whole suit on; just insert your hand in the sleeve and slide it
through the wrist seal as explained in the section Putting on your dry suit. Adjust the seal so
that it lies at against your wrist. It should be snug, but not uncomfortable.
!! WARNING !!
If the seal is too tight blood circulation to the hands will be restricted and could cause your
hands to become cold or numb. This can make it difcult or impossible to operate equipment.
6.3 Connecting the low pressure inator hose to the regulator
You must connect the low pressure hose that is supplied with your dry suit to a low
pressure port on the rst stage of your regulator before you use your suit. Low pressure
ports are 3/8’’ UNF (9.5 mm). The maximum output pressure of an LP port should be
225 psi (15 bar). The hose must be routed so that it comes under your left arm. Accordingly,
the hose must connect to a port on the “left” side of your regulator as it sits when it is
connected to your tank.
To connect the hose to the rst stage, you must remove one of the low pressure plugs from
the rst stage of your regulator. The post must either be marked “LP” or it may have no
marking. Under no condition should you use a port that is marked “HP” or “high pressure”.
Use an Allen wrench or open end wrench as appropriate to remove the low pressure plug.
Keep the plug in a safe place in case you change regulators. Once the plug is removed,
screw the low pressure inator hose into the opening and tighten with a wrench until snug.
If you are uncertain of how to perform this procedure, have it done by your dry suit or
regulator dealer.

18
!! WARNING !!
Do not connect the VIKING™ low pressure inator hose to a high pressure (H.P.) port.
The hose may erupt causing serious injury.
!! WARNING !!
Do not substitute any hose for the hose that was provided with your dry suit. Even though you
may be able to couple another hose to the low pressure inator, the ow capacity through
the quick disconnect may not be adequate to supply the inator valve. In addition, if the hose
is too short and bent, kinked or otherwise restricted, the inator valve on your suit may fail to
operate properly.

19
7. Pre-dive inspection
At the dive site, you will need to spend a few minutes getting your suit ready to go diving.
There are certain items that should always be part of your pre-dive check for dry suit diving.
If your dry suit has been in storage for more than a month, be sure to inspect your suit
several days before you leave home to go diving. Give yourself enough time to make any
necessary repairs or to have them done.
7.1 Zipper
Always check the zipper on your dry suit before diving. You should be able to close the
zipper with a single nger pulling on the loop. If the zipper is hard to pull, lubricate it with
either zip lube, beeswax or parafn wax. In an emergency, you can use a bar of soap for
lubrication.
To lubricate the zipper, close it all the way and lubricate the outside of the zipper only.
Inspect the teeth for damage, or teeth that are not in alignment. Either of these signs
indicate a damaged zipper. If these signs are present take your dry suit to the closest
VIKING™ dealer for inspection and repair.
! CAUTION !
Do not use silicone spray to lubricate your dry suit zipper. Silicone spray can damage the fabric
of the suit and the tape that forms the base for the zipper.
7.2 Latex seals
Check latex seals. In cold and low temperatures latex parts become stiff and brittle. Warm
them gently to around 99-104 °F (37-40 °C) to soften them and improve ease of donning.
You may use a hair dryer or a similar source of gentle heat for this purpose.
7.3 Inator and exhaust valves
Prior to each dive, check the operation of both your inator and exhaust valve. Test the
inator valve by hooking up your regulator to a scuba tank and pressing the inator button.
To check the exhaust valve, seal the wrist and neck seals with rubber bands and inate the
suit until air escapes from the exhaust valve. Push down on the top of the exhaust valve to
check the manual override function.

8. Putting on dry suit underwear & dry suit
8.1 Putting on your dry suit underwear
When the weather is warm topside, you’ll want to set up all your other diving equipment
before putting on your dry suit underwear and suit.
To put on your dry suit underwear, start by sitting down. Pull on the lower portion of your
underwear and boots (or socks) while you are still seated. Tuck the legs of the underwear
inside the boots.
Hold the upper part of the underwear as you stand up. Slip one arm into the underwear and
then the other. You may need your dive partner to assist you with this, especially to get the
underwear up over your shoulders. Do not force the underwear over your shoulders. Close
the zipper on your underwear when it is in position on your upper body.
