When finding the best location for your swim spa, think safety first: Never position a spa, swim spa, or any other type of pool near over- head cables or power Ines. Make sure that if the swim spa is to be positioned near a slope, dip, trough or below ground level, there is adequate drainage for any ground water to run off. Damage caused by flooding is not covered under warranty.
If you are building a deck around the swim spa, sinking it slightly, or placing it against a wall, ensure easy access is provided to all service panels. Swim spas are heavy and typically require a crane or machinery to move them even without water; therefore, you must ensure that you leave complete access to all panels of the spa in case of an issue in the future.
Proper planning will enhance the enjoyment of your spa experience and protect your privacy.
Do you need quick and easy access? If so, placing swim spas close to the house or changing room is ideal. Do you have a view to admire from the swim spa? If so; consider how the swim spa can be best rotated so the seating faces the view without obstructing the service panel.
For most, the reason for buying a swim spa is to be able to swim in it! As such, swim spas have 2 or more larger pumps, that drive the swim stream. When not in use, swim spas use surprisingly little power, however with the swim pumps on, this power draw increases and therefore adequate power supply is crucial to get the most from your swim spa.
Below is a table outlining the maximum and minimum power requirements for each model of swim spa. Please note that if you do not have the maximum power requirement available, the swim spa will be set up so that the heater will turn down when one or more of the swim pumps are activated. Within Australia and New Zealand, these will be single-phase power supplies, however, the swim spa can be configured to use either 2 or 3 phases if required.
Note: All Connections over 15 amps will require Hard wiring from a qualified electrician.
If you are preparing a new base for your spa or installing onto a deck and would like to conceal the power, please follow these instructions. Valid on all swim spas made after 7th February 2018: Mark out where your spa will sit on the base using the provided dimensions. Measure 1000mm from the touch pad end of the swim spa and 400mm in from the right side of the spa (while facing the key pad end of the swim spa). You can have your electrician run the conduit and cable before the concrete is poured so that it can enter through the base of the swim spa at the noted location which will conceal the power entrance.
|Note: The conduit should not stick above the concrete more than 150mm.|
When the swim spa arrives, you will see the 200mm hole in the base of the swim spa which will be covered by insulation. The insulation has a slot in it and the conduit can be pushed up through the insulation as the swim spa is placed.
|Note: Most local authorities insist that your swim spa is separated from it's isolation switch by at least 1 metre.|
Your electrician should be aware of this and should be consulted prior to settling on the exact position of your swim spa.
Whilst there is some variation from councils regarding fencing requirement for spas, you should assume that the council will want to see a fence of 1.2m around the swim spa. This can often be avoided if the swim spa is installed above ground, as swim spas are generally more than 1.2m high. However if this is done, the council will require that the steps are removable and there are not other items around the spa that can be used as a step.
This includes heat pumps. As such, if you wish to avoid fencing your swim spa by leaving it completely above ground, the heat pump will need to be installed at least 1.2m away from the side of the swim spa.
|Note: This is a guideline only; please consult directly with your local council on your legal obligations regarding the installation of the swim spa|
When a swim spa is full and depending on the model it can often weigh in excess of 9 tonnes. As such, it needs a very firm base. We recommend 100mm of re-enforced concrete.
Delivery of your swim spa Cranes and Hi-abs
Due to the weight of your swim spa, they are required to be craned into position, the crane required is dependent on your access and position of the spa. Cranes are not as expensive as some would think, and it is important to use the right crane for the job to avoid unnecessary costs.
If you have not already discussed delivery access with your salesperson, please do so as soon as possible. Depending on the access you have, you may be able to crane the spa into position using a truck mounted hi-ab, this delivery can be the most cost efficient however it requires the truck to be able to drive within an appropriate distance to the intended location of the spa. (Typically, 5 metres)
Stand alone, truck mounted cranes will have a much larger reach. However, these cranes are often very wide and very heavy with many not being able to drive on a domestic driveway. It is very unlikely that a crane of this type will be able to operate from grass or ’off road’, but some all-terrain cranes are available. In all cases please consult with your salesperson they can point you into the right direction, it is best to have everything arranged well before delivery to avoid delays.
|Note: that it is virtually impossible to move a swim spa by hand.|
Once in position, it is there to stay and so it is vital that it is placed in its final position whilst the crane or hi-ab truck is on site.
Above Ground Installations
This is the most common and certainly the easiest method of installing a swim spa. You simply lay a concrete pad as described above and crane the swim spa onto it. You then have a choice of either using the removable steps for access, or building decking up to the swim spa as seen to the right.
If you are decking up to the swim spa, the sides of the swim spa must still be accessible and most importantly, there must be access to the equipment bay at the spa seating end of the swim spa.
This can be achieved using removable decking sections or trapdoors.
Installing your swim spa into the ground
When excavating your hole, ensure that you allow an extra 500mm from each side of the swim spa and an extra 1000mm at the spa end for access to the equipment bay. If a heat pump or pit drain is being installed below ground level, sufficient room must also be allowed for these items. As such, a swim spa measuring 4m x 2.3m would require a hole that is 3.3m x 5.5m
Below ground layout for a swim spa
The walls then must be retained this can be done with timber, bricks or concrete.
Drainage of the pit needs to be fitting. A full-length drain should be used that either gravity drains to the outside of the pit or drains into a sump with an automatic submersible pump fitted.
The base needs to be concreted – make sure of your heights and what height you want the swim spa to finish to sit flush in relation to any decking.
(Optional) Using a liquid filler, fill all the gaps in between the timbers and then paint using a black seal waterproof paint. This will stop any seepage from the dirt in to the pit.
If you do not have the option of gravity draining the pit, a sump pump should be installed. These are a very reliable and relatively inexpensive solution.
Your swim spa can now be craned into position
Once the swim spa is in position, you can complete the decking up to the spa.
|Note: it is important that access is available to all sides and most importantly, the equipment bay of your swim spa. This can be achieved using removable decking panels. Failure to take this into account could lead to significant costs if your swim spa needs to be serviced in the future.|
Heat pump placement and installation
Heat pumps are a fantastic method of reducing the heating cost of your swim spa.
See our Heat pump Installation article or the Installation Section of our knowledge base for more detailed information. Following are a few considerations when selecting the placement of your heat pump:
- The heat pump measurements (955mm wide x 305mm wide x 550mm high)
- The heat pump is connected to your swim spa with 2 x 40mm plumbing pipes, a power supply (the heat pump takes its power from the spas controller) and a data cable. These enter the side of the swim spa via holes that re cut in he swim spa’s cabinet by the installer.
- The heat pump must be a minimum of 1.2m and a maximum of 3m from the edge of the swim spa
- The heat pump should be installed at the same level as the base of the swim spa. If your swim spa is being sunk into a pit, the heat pump needs to be installed in the pit with the back side of the heat pump 300mm off the edge of the pit, and the front side of the heat pump facing across the front side of the swim spa to ensure it has adequate air flow.
- The heat pump must sit on either a concrete base, or well laid concrete paving stones. The most common solution is to pour a pad extension for the heat pump when the main pad is poured
- The heat pump moves a lot of air and so both the back and front of the heat pump must be completely unobstructed. The manufacturer recommends 300mm at the back, 500mm each side and 2.5m to the front of the unit.
- The heat pump is very quiet (49dB), but you should avoid placing your heat pump outside of a bedroom window for example.
- If you wish to avoid fencing your spa, the heat pumps plumbing should be fitted low to the ground so as not to be used as a step.
- Heat pumps should be secured to the concrete pad using dyna-bolts or similar.
