Advice
The Evo8 Hotwater Suit is a Commercial Diving Hot Water Suit. It’s strongly suggested that
if you are planning to dive in the Evo8 Hotwater Suit you should read and fully understand
these instructions prior to diving.
The Evo8 should only to be used by individuals who’ve received training specically for
using it, or who are being instructed by an industry recognised instructor procient in the
use of Hotwater suits.
Our Hotwater suit is not a buoyancy aid. The Evo8’s buoyancy will decrease with depth.
It’s very unlikely and incredibly rare but scalding can occur. To reduce the effects of
scalding, we recommend you wear an undersuit, base layer or a form of thermal garment
under your Hotwater Suit.
While using the Northern Diver Hotwater Suit, if you expect a work rate increase please
watch for signs of over-heating (hyperthermia) and take immediate action.
Please note, although rare, some people have an allergic reaction to some types of
neoprene or latex. If while you’re wearing your suit any sort of rash appears, remove the
suit immediately and seek medical advice. We recommend that you perform a full ow test
prior to each dive.

Made from 4mm compressed neoprene that’s shrink resistant, the density of the neoprene
is increased through the compression process giving the Evo8 Hotwater Suit its massively
improved strength. The Northern Diver Hotwater Suit is manufactured from materials which
provide the same maximum comfort whilst ensuring excellent resistance to wear and tear.
As with all our diving products, performing proper care and maintenance, as outlined in this
manual, will ensure an extended product life.
Features:
Moulded and overprinted shoulder, knee and elbow pads
Easy to maintain valves
Hook and loop fastening to secure wrists and the zip
Side zip on ankle to taper the suit t
2x Reinforced bellows pockets
Blind stitched, internally reinforced and sealed seams
We’ve developed our suit to be:
Low friction
- allowing the suit to slide easily whilst being put on and taken off and also during diving.
Lightweight
Low bulk
Ease of movement
Ease of adjustment of the hot water supply
The Northern Diver Hotwater Suit is compatible with all Commercial Diving hot water
systems. The suit is compatible with all Commercial harnesses and recovery vests.
(Although we’d recommend you use our Northern Diver R-Vest or Safety Harness).
If sizing allows, the Evo8 can be used by male or female divers.
Designed to be used as a commercial hot water suit, the Evo8 Hotwater Suit was
developed to attach to a hot water delivery system. The suit is designed to be used in an
environmental temperature range of 2°C (35.6°F) to 20°C (68°F)
The size of the suit is printed on the left chest above the name label as well inside on the
Hotwater Suit’s information panel. When choosing a suit, please select one that’s closest
to the wearers body dimensions - height, chest and C-Floor. For more guidance on this,
please check our Hotwater Suit sizing guide. Provision for urination is not required as the
suit is not a drysuit.

HotwaterSuitSizeChart
Wearing an undersuit:
You’re the best judge of your body’s thermal protection requirements. Always consider
undersuit specications and combinations to best meet your requirements.
Hot water can scald; the dive superintendent must ensure the hot water supply
temperature is correctly set and the diver should always wear an undersuit of some
description as a barrier which will prevent direct contact with the hot water being supplied
through the suit.
Evo8’s Thermal Insulation value: 1.06 to 1.08 TOG (mean). Essentially there’s no signicant
thermal insulation protection. The Northern Diver Hotwater Suit is designed to be worn over
a wetsuit or a diving undersuit (we recommend our Thermalskin undersuit) that’ll act as
an outer heated suit and protection layer. Without its hot water supply, the suit itself offers
no signicant thermal insulation or protection from the cold. The Evo8 should be worn in
conjunction with diver’s underclothing to provide additional insulating layer(s).
Please check your suit before and after use
Before use
• Make sure your suit’s zip is in good working condition
• Ensure the water distribution valve is secured tightly to your suit
• Perform a full ow test before each dive
After your dive
• Make sure there are no rips or tears on your suit
• Ensure the suit hasn’t picked up any dirt or contamination that’ll degrade it
• Clean and dry your suit (as per our cleaning instructions in this manual)
In the event of the suit becoming torn or damaged, it should ideally be returned to your
local Hot Water Suit distributor for inspector. The distributor will be able to advise whether
the equipment should be repaired or replaced.

Hotwater Suit Care Instructions
Washing
Use cold, fresh water to rinse your suit thoroughly after every use.
Dry your suit naturally at a normal room temperature, out of direct sunlight.
If the suit is soiled you can use luke warm, clean water to wash it. If your Evo8 is
particularly severely soiled, you can wash it in a mild detergent, however we suggest this is
only done occasionally.
From time to time we also recommend that you apply silicone spray to the zip.
Tumble drying may cause suit shrinkage
Diesel and Oil
While using your suit, you could come in contact with diesel or oil. These liquids will
eat away at your suit and will have a detrimental effect on the life of your suit. To slow
this process, we recommend that you regularly rinse your suit in fresh water. If your suit
becomes degraded by diesel and oil this will void your warranty and we can’t offer a
guarantee against this.
Storage
After use, the Evo8 Hotwater Suit must be thoroughly cleaned and dried. You can then
either:
Fold your suit loosely and store it in a large bag or container, or
Hang your suit on a suitably sized hanger (we recommend our multi-purpose hanger)
Always store in cool dry conditions and keep your suit out of direct sunlight to extend the
product life.
Do not leave any neoprene suit folded in a damp condition for longer than absolutely
necessary. Be aware, neoprene will crease if not stored correctly.
We supply the Northern Diver Evo8 Hotwater Suit in sealed, plastic packaging. This should
be removed before use and can be recycled.

Suit Maintenance
Please follow the cleaning and suit check guidance that’s outlined in this manual.
Valve & Piping Maintenance
Periodically ush the valve and tubes through with clean fresh water. You don’t need to
remove the valve from the suit to ush it.
Inspection Intervals
Your Evo8 should be checked before and after each dive.
If your suit has been stored for any length of time, it should be thoroughly checked and
ow tested before it’s re-commissioned and used.
Repairs
Small and simple repairs to your Evo8 can be carried out using a quality neoprene
adhesive. However, we’d always advise that repairs and alterations are carried out by a
trained and skilled repair technician. In the event of the suit becoming torn or damaged,
it should ideally be returned to your local Hot Water Suit distributor for inspector. The
distributor will be able to advise whether the equipment should be repaired or replaced.
Modications
Under no circumstances should you modify the suit (unless trimming the arms and legs)
without the knowledge and consent of Northern Diver, the manufacturer. Any modications
outside of trimming the arms and legs would nullify your warranty and could affect the
Hotwater Suit’s PPE status and CE approval.

assessment. Please note: modifying your suit or exposing it to diesel and oil which will
degrade it nullify this warranty.
Terms and conditions:
Regardless of where you have bought your Evo8 or where you intend to use it, it’s been
sold to you on the understanding that only English Law applies. Please bear this in mind in
the case of any and all warranty or product liability claims.
