6. Heating the Weva Octo+ 840 Pool:
If you are looking to heat your pool, you have the choice of two options:
- Electric Heater which is cheap to buy but expensive to run
- Heat Pump which is slightly more expensive to buy but is a lot cheap to run .
This pool has 42m3 of water so these heating options will be ideal:
1/ Electric Heater which is cheap to buy but expensive to run and will heat your pool all year long.
You will achieve 1 Kw of heat output into the water for every 1 Kw of power used from your supply. So works out a lot more expensive to run than the Heat pump option.

2/ If you are looking to use a Heat Pump to keep the running cost down then you have to decide which months of the year you want to swim:
If you are looking to use a Heat Pump to keep the running cost down then you have to decide which months of the year you want to swim:
- Summer (May - Sep)
- Extended Season (Apr - Oct)
- All Year
Once you have decided this you can than look to see which heat pump is the best one for you. Now this will vary depending on the pool's location in the country as the outside air temperature is drastically different in Scotland from Cornwall's air temperatures (taking into account the worst temperatures at night and the coldest parts of the period you choose).
We can help size the correct unit for you to ensure you achieve the desired water temperature (normal temp for this pool is 28 degrees, and it should not be heated over 30 degrees as this reduces the life span of the liner).
As a rough guide for this pool we have added some options at the top of this listing for you, but here is a explanation to the season to expect from each. Please bear in mind that you can never over size a heat pump but the results of under sizing it will mean you will not have the water temperature you require for the period you want. In addition to this, if you are further up North (in a colder area) please increase the size of your heat pump to compensate for the colder outside air temperatures:

7. Installation and Assembly of the Weva Octo+ 840 Pool:
The pool can be assembled by most competent DIY installers, or the customer can choose to use a local carpenter or handy-man to assemble the pool.
A qualified electrician should be used to run the power supply to the pool and to make the necessary connections.
A flat, level concrete slab should be laid to take the weight of the pool and to avoid it moving or sinking once filled with water.
Underlay (Ground Sheet on the base only) is supplied with the pool which is laid under the liner to help protect it from damage
Please see the user manual for details of how to install the pool
Please ensure that you have sufficient time, labour, tools and the skill required to assemble the pool before purchasing

10. Warranty and Upkeep of the Weva Octo+ 840 Pool:
The warranty on the Weva Octo+ 840 Pool is
- 10 years on the structure & pool fittings
- 5 years on the filter tank
- 2 years on the ladder, Filter lid & pump and liner (Please note that you must NOT push down on the filter handle, as any damaged caused will not covered under the warranty)


Upkeep of the structure of the Weva Octo+ 840 Pool
Wooden components: 10 year guarantee from the manufacturer against insect infestation and rotting (wood is high pressure autoclaved in accordance with the standards in effect). This guarantee does not cover natural warping of the wood (appearance of cracks, splits that in no way impact the mechanical strength of the wood) or changes in colour attributable to weathering. Defects resulting from errors in mounting or storage are also excluded from the scope of this guarantee: deformed wall slats (exposure to sunlight, assembly deferred after opening the package), slats altered or broken due to assembly in a manner other than that set out in the installation instructions. Given the continuous pressure exerted by the water, the pool walls may become slightly curved over time. This phenomenon, which is a result of the natural elasticity of wood, will stabilise by itself over time and will not lead to failure or breaking of the wooden slats. This is not a defect, and will not be considered grounds for a guarantee claim. Furthermore, application of a product such as wood stain will result in cancellation of the guarantee.
Water Treatment and maintaining water quality fro the Weva Octo+ 840 Pool
To ensure the comfort of pool users, you will need to treat the pool water. Follow the recommendations concerning operation of the filtration group: commissioning, frequency of use for regeneration of the water, maintenance, inspections (pipes, nuts and bolts), etc. Monitor the build up of dirt in the sand filter (see the section on filter back washing). Similarly, check that the filter openings are not blocked.
• Filtration should be stopped before any maintenance interventions on the filtration system.
• Filtration should be stopped before performing any maintenance on the filtration system.
• Access to the pool should be prevented in the event of a malfunction of any component of the filtration system.
• Any damaged or worn elements should be replaced immediately.
• Only use parts approved by our after-sales service.
During the pool season, the filter should be run every day for long enough to renew the entire pool water volume at least three times every 24 hours. To ensure optimal efficiency of the filtration system, make sure that the water level remains correct and constant. The water level should be 2/3 of the way up the skimmer mouth. To fill your pool, use tap water, its pH is close to the ideal pH. If you use water from a well or some other private source you must have it tested beforehand. You will need to test the pH of your pool at regular intervals and adjust it if necessary to keep it between 7.0 and 7.4. The necessary treatment chemicals are widely available. To preserve the quality of the pool water, it will need to be tested and treated regularly. Frequency will depend on a number of conditions; pool situation, bather load, weather conditions, etc. You should inform yourself regarding the use of the chemicals your may need to treat your pool and maintain good water quality.
FAILURE TO RESPECT THE MAINTENANCE RECOMMENDATIONS MAY ENTAIL SERIOUS RISKS TO HEALTH, NOTABLY THAT OF CHILDREN
Once the pool is filled, the water quality will naturally begin to degrade due to pollutants carried in by bathers (bodily secretions, but also twigs, grass, earth, sand, etc. stuck to their feet and their skin), as well as pollutants carried by the wind (leaves, petals, pollen), and insects. The water will therefore need to be replaced periodically. The frequency of replacement will depend on the water temperature, the bather load, the length of the daily filtration window and the use of pool chemicals.
Filtration slows the natural degradation of water by trapping tiny particles (from a few millimeters across to a few tens of microns). The length of the daily filtration window necessary will mainly depend on the level of pollution carried into the water and the water temperature. For information purposes, while the pool is in daily use, the minimum filtration times recommended are as follows:
CAUTION🚩Please do not push down on the handle of the pump and filter as this will cause damage to the filter that is NOT covered under the manufacturers warranty.
CAUTION🚩 Carry out a back wash and rinse before using the filter for the first time to clean the filter and remove any excess sand and impurities (see the paragraph Filter and Valve operation). After the back wash, rinse before turning the valve to the Filtration position. After the back wash, with the multi-port valve set to Filtration, the black needle on the pressure gauge indicates the nominal pressure experienced by the filter. This pressure will vary as a function of the pump flow rate, the static pressure and load losses across the pipes. To keep a record of this nominal pressure (calibration), adjust the dial of the pressure gauge so that the blue needle aligns with the black needle.
IMPORTANT🚩 Stop the pump before each manipulation of the 6-way valve. Failure to respect this instruction could result in damage to the insides of the filter, the valve or the filter itself and will result in cancellation of the guarantee. • Before starting the pump, make sure that all the 1/4 turn valves are open and that the 6-way valve is set to “Filtration”.
Correct use of your pool requires optimal water treatment. Clean the cartridge regularly (refer to the cleaning protocol described in the filtration manual) and make sure that the daily filtration window is long enough .
Please see the attached installation manual for further information (as per section 14)
Winterising of the Weva Octo+ 840 Pool:
Carry out a prolonged back wash of the filter. The pool should not be emptied during winter (or prolonged periods while the pool is not use). The liquid mass plays a several roles, providing thermal insulation, holding the liner and pool structure in position. Lower the water level to about 10 cm below the bottom of the skimmer mouth. Water can be siphoned from the pool or allowed to drain by gravity by moving the multi port valve to DRAIN. Water will run through the waste line. Do not run the pump during this operation. Next, disconnect the pipe underneath the skimmer so that it can act as an overflow in the event the water level rises due to precipitation. Remove any water treatment chemicals from the skimmer (chlorine tablets,
flocculent, etc.). Unscrew the return fitting face ring from inside the pool. Use a threaded winterizing plug or rubber plug (not provided) to block the return fitting from inside the pool.
Add an algaecide and a winterizing product (not supplied) to the water. Remove the stainless steel ladder. Place a winter cover over the surface of the pool.
NOTE: Winterizing is not mandatory, especially if the weather is clement and temperatures remain positive. In this case, maintain a correct water level in the pool and run filtration 2 to 3 hours per day. Check the water level in the pool regularly
Winterizing the hydraulic installation. Disconnect the return line. Allow water to drain from the suction and return lines. Open the plug at the bottom of the filter and allow water to drain away. Do not replace the plug before putting the filter back into service. Open the drain plugs on the pump and pre-filter. Leave the plugs open. Cut the power supply to the filtration control panel. In as far as possible, store the filtration group in a location protected from humidity. In the case of an unprotected outdoor installation, remove the pump and store it.
The pool must not be left empty over the winter period (or for any prolonged period of time). In fact, the liquid mass plays a dual role, it provides thermal insulation and acts as ballast, holding the liner in place against the pool structure.
Please also ask for information with regards to winterisation of the heat pump and other equipment you may purchased.
