Winter – Potential Frost Damage
If your tub is going to be left empty over the winter months or in any very cold climate where there
is a possibility of sub zero conditions it is very important to remove all the water from the pipework
and pumps as well as from the tub itself.
Water that freezes in the pipework and pumps can expand and crack the pipes and pump wet ends
leading to major leaks, which will leave your tub unusable and will need an engineer to repair. Frost
damage is not covered in the warranty on your tub.
Your hot tub water needs to be treated with certain chemicals to
maintain its cleanliness.
Sanitiser levels, Ph Levels and Total Alkalinity can be measured with readily available water testing
strips. As you use your tub, chemical levels will change as they do their job, keeping the water clean.
Remember to only add small quantities of chemicals to your water as once it is
dissolved into the water it is impossible to take any out.
Sanitiser
Sanitiser, chlorine or bromine can be used in either granule or tablet form. Granules dissolve into the
tub water quickly and can be used to boost chlorine levels quickly. Tablets are slower to dissolve and
are floated around in the hot tub in a floating dispenser. This can keep Chlorine levels more stable,
reducing the need for regularly dissolving granules into the water. Never mix Chlorine and
Bromine in the same water !
Ph
Also required is a chemical for controlling the Ph of the water. Either a Ph increaser or a Ph Reducer
can be used to keep the Ph within a safe level.
Do not attempt service of this control system. Contact your dealer or service organization for
assistance. Follow all owner’s manual power connection instructions. Installation must be
performed by a licensed electrician and all grounding connections must be properly installed.
