What to do?
The purpose of maintaining the water of your pool is not only to protect the swimmers, but
also to improve the working conditions of your pool equipment, particularly of your pool heat
pump to increase its durability and its efficiency. To achieve this goal, the user must:
1. Test pool water regularly (chlorine or bromine, pH and total alkalinity);
2. Balance the pool chemistry within the level of the standards using the appropriate products;
3. Protect the pool heat pump whenever the water should be beyond the standards.
1) Testing
We highly recommend checking the level of chlorine or bromine, and the level of pH and
TA at least once a week. Moreover, we suggest that you have your water tested professionally
once a month, particularly the following variables:
· Calcium hardness: a low calcium hardness level implies corrosive water that can
damage your pool heat pump. A high level of calcium hardness contributes to the
formation of deposits on the surface of the heat exchanger reducing the efficiency of
the pool heat pump;
· Total dissolved solids: a high total implies a tendency of the water to corrode, therefore
gradually destroys the pool equipment;
· Copper level: a high copper level can indicate a degradation of the cupro-nickel heat
exchanger of the pool heat pump. So this can be considered as a warning urging you
to verify the pool water more often. For the users of copper algaecides, a higher level
of copper is normal; but verify if there is no gray-black stain deposit indicating the
saturation of the water in copper and a possible degradation of the heat exchanger;
· Stabilizer (cyanuric acid): a high level of cyanuric acid can damage the equipments
and, especially, is toxic for the swimmers.
2) Balancing
According to the levels given by the test results and according to the volume of water of
your pool, always balance the pool water in a manner that meets the standards. Your swimming
pool service company can help you choose the proper chemical products and the appropriate
quantities. Always carefully follow the instructions given by the chemical products suppliers.
Never pour more into the water than prescribed.
Warning: any chemical product, acid or basic, is susceptible of provoking the
degradation of the heat exchanger of your pool heat pump. Never pour any chemical
product into the water intake (skimmer) of your pool to prevent the product from
damaging your pool heat pump.
3) Protecting the Pool Heat Pump
If you observe that your pool water is beyond the established standards, we urge you to
shut down your pool heat pump, to divert the water from it and to disconnect it from the plumbing,
as described in the section “Maintenance”, p11. After, wash the heat exchanger using tap water.
