Inating.
1. Remove the inatable from the valise provided. It isn’t necessary to unroll the inatable
for ination.
2. The ination valve has two positions. When the valve is closed, the diaphragm pin will
be in the raised position. To open the valve, press and twist the diaphragm pin clockwise.
When closing the valve, twist the diaphragm pin anticlockwise until it releases into the
raised position.
3. Please ensure the ination valves are in the closed position before inating.
4. Insert the ination hose into the inlet valve on the main section and twist
clockwise to lock it into place. You can then begin to inate. When using a BA cylinder to
do so, this will take less than 60 seconds. Take care not ll to maximum capacity. When
the rst section is inated, remove the hose by twisting anticlockwise.
5. The ination process can then be repeated on each part of the inatable. To save time,
you can use multiple hoses to inate two sections simultaneously (additional hoses are
available to purchase). Please take care not to ll to maximum capacity.
6. When ination is complete t the valve caps by inserting them and twisting clockwise.
OPERATING INSTRUCTIONS
Deployment & Use.
The following points are operational recommendations. Almost every operational
scenario will have different hazards and risks, which can only be properly assessed at, and
during, an operational rescue/recovery.
WARNINGS:
Ensure equipment is used only by trained personnel. Do not drag the inatable. Avoid
contact with sharp or abrasive objects as they may puncture the fabric causing a loss of
buoyancy. Walking an inatable is only suitable for calm/slow moving water. Any
non-approved modication will invalidate the warranty and may result in personal injury.

WARNING
During use on water, mud and suspect surfaces, personnel should wear a
”Lifejacket” or similar buoyancy aid, and / or be linked to the inable via a
safety line. Failure to do this may result in personal injury or death.
Securing lines
When using an inable in fast owing water, use securing lines attached to the
front towing ’D’ ring and the towing ‘D’ rings on the sides to manoeuvre and secure the
inatable to convenient tie points on the bank / shore.
Towing
The inatable may be towed behind a parent craft at a maximum speed of 5 mph. The
tow line must be secured to the front towing ‘D’ ring. If the inatable is to be towed in rough
water or for an extended time the tow line must be attached to a bridle secured between
the towing ‘D’ rings on either side of the inatable.
Manoeuvring
The inatable can be manoeuvred by one person using paddles (if supplied).
It can also be manoeuvred in shallow water by persons walking alongside holding the
carrying handles.
NOTE: Walking an inatable is only suitable for calm/slow moving water.
Stability
Wherever possible evenly distribute the weight of persons on the inatable to avoid
instability that may lead to capsize.
Righting Strap
A loop strap is tted on the underside of the inatable to aid righting of the
inatable in the event of capsize.
WARNING: Unless otherwise specied most inatables are not designed for any type of
motorised propulsion. The tting of any type of motor, or any other modication to the
inatable is not advised. Any non-approved modication will invalidate the warranty and
may result in personal injury.
Deating.
1. Remove the ination valve caps.
2. Open all valves by pressing and twisting the diaphragm pin clockwise.
3. Turn the inatable upside down, and ensure that the oor is facing upwards. Begin to
fold, starting at the opposite end to the ination valves. While folding you will release any
excess air from all sections of the inatable.
4. Once folded/rolled, we recommend that the ination valves are closed and the valve
caps are in place. The will prevent dust/debris entering into the valves.
5. For an additional cost Northern Diver can supply a mains powered Speedy Air Pump,
which can rapidly inate or deate any inatable.

It should be noted that, due to the type of fabrics used in its construction, when the
inatable is wet, there may sometimes be visual evidence of miniscule white bubbles
which form a line of froth at the seams and joints of the unit. This is recognised within the
industry as ‘lateral leakage’, and is simply air that is trapped in the layer of nylon between
the rubber coatings, forcing its way to the nearest available edge of the fabric. This type
of leakage will not affect the performance of any inatable product over the course of an
operational procedure, and can be safely ignored. However, if there is evidence of large,
transparent bubbles, this is clearly evidence of a leak that must be repaired at the earliest
convenience.
Every six months
A visual inspection is recommended. This can be carried out in-house by your maintenance
department/workshop (Northern Diver will provide necessary training at no additional cost).
Inate as per a normal deployment. Leaks can be detected by dousing the with soapy
water. If a leak is present, bubbles will appear constantly on the affected area. If a leak is
located around a seam or valve, Northern Diver will carry out any necessary repairs under
warranty. Additional leaks can be repaired by Northern Diver and self adhesive repair
patches can be purchased online. Each pack contains 3 x 50mm discs and 3 x 100mm
disc patches. This will enable you to repair any leaks/punctures in-house. If the ination or
over-pressure valves are accidentally damaged, Northern Diver can repair or replace.
Every 12 months
An annual service is required. There will be no additional charge for this service. Northern
Diver will collect the inatables and give each one its 12 month annual service. This
includes the following: ination, leak test, valve inspection and deation. The ination
kit will be serviced at the same time. Northern Diver will collect and return the serviced
inatables within 3-5 days.
MAINTENANCE / SERVICING
PACKING / CLEANING
After every use, especially on mud ats, the inatable should be hosed down in its inated
state, to remove as much debris as possible. Lay the intable on a clean, debris free area
and allow to become as dry as possible before packing. Rinse all valves with clean water to
remove any debris like sharp stones, dirt or sand and leave to dry.
If cleaning immediately after use is not possible, stow in the valise temporarily after
checking for stones.
On return to base the inatable should be unpacked, inated and left to dry. When the
inatable is completely dry it should be checked for wear or damage. If none is found
it should be repacked in the valise. If any damage is found it should be repaired
immediately. Where possible the packed inatable should be stored on the oor of a locker/
appliance, ensuring no damage can be caused by it’s proximity to other equipment. We
advise you clean the inatable within twenty-four hours.
Note: Household detergent mixed with warm water can be used with a scrubbing brush for
any difcult patches of mud or oily deposits.
