OPERATING INSTRUCTIONS FOR
SWIMMING POOL HEAT EXCHANGERS
___________________________________________________________________
After the heat exchanger has been correctly installed, emphasis should be given to the general
maintenance of all the pool equipment, the most important factor which will have a direct
bearing on this will be the pool water condition. The proper purification of the pool water will
allow for a healthier pool, the water will not cause discomfort to bathers, it will not cause a
break-down of pool equipment and will not cause any unpleasant smells which are often
experienced with wrong chlorine dosage. The ideal pool pH should be kept to within 7.4 to
7.6. On no account should it fall below 7.2 or above 7.8. If this is not achieved
corrosion/erosion of the pool equipment will occur.
Listed below are some guides on operating conditions for the heat exchanger:
a. Always keep pH to within correct levels. Check on a day-to-day basis. Alter pool
condition as necessary.
b. Ensure the free chlorine levels are within the range recommended by the chemical
manufacturer and are in accordance with the type of pool, for example, private,
hotel, school or municipal.
c. If a by-pass is fitted to the heat exchanger circuit, it is essential that any valves are
correctly positioned and allow the recommended pool water flow to pass through
the heat exchanger. Incorrect flows may cause corrosion/erosion.
d. The filter unit should be checked regularly. This is very important especially with
sand filters. This sort, if working incorrectly, can allow sand to pass around the
pool circuit causing erosion of pipe work, heat exchanger and pump unit.
e. Keep pool free from debris such as leaves, grass cuttings etc. This foreign matter
can decay and increase pH:
f.
It is essential that the correct amount of chlorine dosage is added to the pool. To
allow proper dispersion of the dose in the pool water; distribute the chemicals to
various areas of the pool. Do not dose in one area only, as this will create high acidic
areas which can cause corrosion/erosion of the pool equipment.
Pool water which is in an unbalanced condition will prove costly for the owner with the
replacement of pool components. It is essential that the manufacturers instructions are
followed correctly as this will give safe bathing and prolong the life of all pool
equipment.
