CARE & MAINTENANCE

The tent and annex of your OPUS® are made from poly-cotton, a canvas type material. This has many benefits as it is breathable 

and results in a cooler interior in warm/ hot weather and a warmer interior when in use in cooler weather conditions. In order 

for the OPUS® to give you years of camping pleasure, the tent section needs to be cared for and MUST NOT be left wet/damp 

when packed away. 

It is, of course unavoidable at times that you will have to pack down your OPUS® when the canvas is 

wet. It is very important that the OPUS® is opened up to dry off as soon as possible and should be done within 24 hours. 

• 

Except for the supplied gas hob, do not use a gas appliance or open flame inside the OPUS® and do not subject the tent 

to fire. 

• 

Maintain adequate ventilation in the camper at all times, especially when sleeping. 

• 

Allow condensation to clear and dry before packing/storing the camper. 

• 

Regularly check the seams of the tent and if required apply some seam sealer such as Kampa Seam Sealer or suitable 

alternative. Follow the product instructions and allow to fully dry before packing. 

• 

Regularly check the Velcro straps and seams, along with the clips on the inner tents. 

• 

Never force the zips of the tent to open or close; inspect for any issues and rectify as necessary. 

• 

Ensure the zips are used and cared for properly, if needed a zip lubricant can be used to allow for smooth operation. 

• 

Regularly inspect the tent for holes, rips/tears and damages and have a suitable tent repair kit for use in emergencies.

• 

Take care when setting up and packing down the camper to ensure the tent, and the annex beading is not caught or 

snagged, should this occur retrace the steps and retry making sure the issue is rectified.

Should a rip/tear occur assess the damage before taking action. If unsure contact us on 925 215 7315 for advice. Small  rips/

tears  can  be  repaired  using  the appropriate repair kit and procedure and may not require a professional or return to us for 

repair; should the damage be significant or exceed your capacity, please contact us. 

• 

Clean the tent with warm water and a soft sponge (without a scourer), this may require complete set up of the camper 

(fully tensioning the tent) depending on the location/severity of the stain; allow the tent to completely dry before packing. 

• 

Do not use washing up liquid, detergent or anything stronger as this could adversely affect the tent or result in some 

damage. 

• 

The tent is NOT machine washable. 

• 

AVOID sharp objects near the tent canvas; sharp/pointed objects and poles should be stored on the floor away from the 

tent to avoid damage. 

• 

When the camper is packed, ensure nothing is sticking out and a proper seal is achieved around the periphery and the 

center (seal to seal contact). 

• 

AVOID strain on the inner tents by loosening the attachment straps when necessary

Your Air OPUS® tent has been manufactured using a polyester/cotton fabric. Before a polyester/ cotton canvas is used for 

the first time, it is important that the tent is weathered. Inflate the Air tent following the inflation instructions when rain is 

expected. When the cotton becomes wet for the first time, the weave of the cotton will close. There is no predetermined 

time for weathering so please do not be surprised if there is leakage through the canvas and seams the first few times it rains. 

• 

Your OPUS® Air tent is made from the best available materials. On first examination, you may find some slight variances 

in color, thick threads, pigment stains and changes due to the weather and the environment. These are all normal and 

will not affect the continuing performance of the product and are not faults or errors.

• 

When your Air OPUS® is not inflated, the window material may pick up some impressions from zips, etc., this is quite 

normal and some of these impressions will disappear over time but some may remain. This is not a fault.

• 

Please ensure your Air Tent is only packed away when completely dry. A wet/damp canvas will develop mildew/mold 

very quickly and damage your canvas.

•  The inside and outside of your tent can be cleaned but only with fresh clean water and a damp cloth. 

UNDER NO CIRCUMSTANCES MUST DETERGENTS OR CHEMICAL CLEANERS BE USED AS THESE WILL 

DAMAGE YOUR CANVAS.

You may also experience, depending on the weather and use, condensation. This should not be confused with leakage. 

To reduce the risks of condensation, please ensure your product is adequately ventilated. Please note that under certain 

conditions, all tents will suffer from internal condensation depending on atmospheric conditions, the weather, the amount 

of moisture in the air/ ground, evening and night time temperatures etc. Condensation can be quite severe causing a film of 

water on the inside of your tent (roof and sides) which may drip onto items in your tent and in severe conditions can leave 

puddles of water.

Zips should be treated with care, use two hands when closing and opening and do not step on them during set up or take 

down. Never force a zip. If a zip opening is tight it is more than likely because your tent is not aligned correctly. Candle wax 

may be used to help a zip run more smoothly.
Please remember that your air tent is a temporary structure made from natural fibers. Please note that in fiber products 

used in outdoor applications, product life may be lower because of attack from UV or acid rain. Discoloration of the fabric 

may be an early indication that your tent has been attacked. To limit damage by UV, where ever possible, please site your 

air tent in a shaded area avoiding direct sunlight. Please be aware that continuous exposure is a more serious problem than 

intermittent exposure, since UV attack is dependent on the extent and degree of exposure. Fabrics can be weakened by 

prolonged exposure to sunlight and use for extended periods in strong sunlight will soon cause deterioration. UV degradation 

is not covered under the air tent’s warranty. The Warranty does not cover air tents used permanently or for display purposes.

Your OPUS® Air tent has been manufactured using a special sewing thread which expands and swells to close the holes made 

when stitching the product. The thread swells and expands when wet. It may take a few times for the holes to completely 

close.

If you suspect your AIR tent has a leak and you have tried 1) removing and capping the main AIR inlet valve and 2) opening 

and re-closing your AIR quick-release valves, we recommend closing off your isolation valves for each beam. These are located 

behind the quarter-circle zips in the roof of your air tent. Twist the rear ring towards the “closed” position as indicated on 

the valve. The Air beam with the leak can be identified by a softening or complete deflation of the beam or a hissing sound 

of air escaping.

 If you are in the field and can locate the source of the leak, you may be able to use the patch kit provided to patch the leak 

as a short-term fix in the same way that you would patch a bicycle tire. When you return home, contact OPUS HQ or your 

dealership and use the AIR Beam map in this manual to order your replacement AIR beam. All AIR beams and valves are 

covered under warranty for two years.

In some cases, you may find that simply by closing the isolation valves your tent stops deflating; this is an indication that the 

issue is in the valve or transfer hose and air is escaping when the valve is open. You can make sure that the gray transfer hose 

is correctly seated on the valve by unscrewing the front part of the valve that holds the gray hose in place. Push the gray 

hose back over the valve and screw the front part of the valve back on. If this does not resolve the leak then it is likely that 
the valve will need replacing. As the isolation valves are integral to the AIR Beam, the whole beam will likely need replacing.
To inspect or replace an AIR Beam, follow the below instructions to disconnect from the main tent. Depending on which 

beam you are replacing and its location, you may find it easier to keep your isolation valves closed with your AIR tent inflated 

to replace the beam. 
1. 

Ensure all LED lights are off & unplugged whilst replacing the AIR Beam and that 12v power is turned off and shore 

power is disconnected. Carefully locate the faulty beam and deflate it enough so that you can manipulate the beam. 

Depending on the location of the beam, this may cause the tent to collapse partially which can cause a trip hazard if 

you are working from inside the tent. We recommend having a second person help to hold the tent up and maintain 

access to the exits.

 

2. 

Unzip the beam from the outer layer protective layer and remove Velcro straps.
