Maintenance
Hot Tubs are renowned for their health benefits and if kept well maintained they will last for years. Please see below for
RotoSpa’s recommended maintenance tips in order to keep you safe and to keep your tub of top condition. We advise an annual
service of your RotoSpa by one of our engineers to keep your DuraSpa in as new condition and to check for any wear and tear of
components and/or pipework. A deep clean of the pipework to remove any build-up of biofilm within is also strongly
recommended.
Please call us for further information.
Filters
Filters are used to catch contaminants and debris in the water and keep it clear of any microscopic particles that can cloud your
water. Filters should be cleaned once a week by using your hose pipe to clean between the pleats, the most effective way of
doing this is by using a high pressure flow and separating each pleat as you clean. You will need to wait for the filter to dry
before inserting back into the RotoSpa. For this reason, we advise purchasing a spare filter for when the other is being cleaned.
It is also recommended that filters are soaked in a filter cleaning solution (ensure they are rinsed afterwards) once a month for a
deep clean. If kept clean your filters should last between 12-18 months. Please refer to page 8 for information on how to change
your filter.
All filters and Chemicals are available at Sutton Pools and Spas, please call to order. Your re order number is FILT0021.
Water balance and Chemical Dosing
Keeping your water well balanced is crucial to ensuring all of the components in your RotoSpa do not become victim to
corrosion, or otherwise. It is also the best way to ensure the water is clean and pleasant for bathers. Please revert to pages 3
and 4 for water balancing guide.
PH
Keeping the ph. balance correct will not only make sure your sanitiser can work effectively but will reduce irritation to the skin. A
high or Low ph. level can also cause corrosion or scale build-up of your RotoSpas’ electrical components which in turn is costly to
replace. As soon as you enter the water any deodorant/make-up/lotions etc. will change the waters ph. levels so it is important
to shower prior to getting in your hot tub and to not wash your swimwear in any detergent as traces will always remain within
the fabric. Any detergent introduced into the water will cause foaming.
Sanitiser
Chlorine and Bromine are the most common forms of sanitiser used to kill any bacteria within the water. To keep the water
clean and safe you will need to ensure a constant level of this sanitiser (see table on page 4). Levels that are kept too high will
again cause corrosion over time and can discolour the hot tubs shell, a constant low level of sanitiser will render the water
unsanitary and will be unpleasant to the bather. Once a week we advise you ‘shock’ your water using a chlorine or non-chlorine
shock (dependant on your chosen sanitiser) to kill any bacteria that is within the pipework. See page 3 Step 5 for dosing.
Always follow individual brands instructions.
Additional Chemicals
Water balance can seem like a mine field especially when you are in an area with very hard/soft water and need to consider
alkalinity/calcium reducer/increaser etc. There are a lot of chemicals on the market for hot tubs which again can become
confusing, algaecide, flocculants, shimmer, oxidiser, anti-foam etc. Whilst you may never need these at any point it is important
you know which chemical is to be used for which problem.
