DuraSpa Models
On DuraSpa models, insert the filter cartridge into the housing so that the top of it sits level with the top lip of
the housing. Next, push the lid firmly onto the housing. Finally, turn the lock ring clockwise over the thread.
There are four equidistant lock points on the housing where the ring can be secured into position. Turn the ring
until the spring loaded tag clicks into one of these points. It is very important that this ring is locked in position,
as the DuraSpa models have a pressurised filtration system.
FILLING YOUR SPA
Do not switch on the power before the spa is filled with water. Running the pump whilst dry will
cause severe damage.
When filling your Rotospa hot tub, make sure the mains plug is safely out of the way, remove the
filter cartridge and fill through the spa filter housing. This will ensure that all the pipe work is filled
and minimises the potential for airlocks to occur.
Each model from our range of spas has its own specific fill level. To find the correct fill level for your
spa, refer to the images below.
Fill the spa to the top of this cut out in the
filter housing front plate. Reinsert filter
cartridge followed by flow plate. Finally, the
filter basket sits on top of the flow plate.
