WATER BALANCE MAINTENANCE

The chemical balance of your pool/spa water and the methods used in adding pool chemicals will directly effect the life of your heater. Like no other precaution you could take, it is very important that these guidelines are followed in order to prevent damage to the heat exchanger/water coil and possibly the entire system.

Improperly maintained water balance and incorrect introduction of pool chemicals will cause extreme corrosion to the heat exchanger. If this condition goes unnoticed, it will eventually damage the compressor and evaporator coil. The heat exchanger in your unit is made of the highest quality cupronickel metal alloy. This makes the heat exchanger as chemical resistant as possible. The heat exchanger will withstand what is considered normal pool water balance. Unfortunately, chemical damage is usually diagnosed after the unit has failed because the corrosive pool/spa water attacks the metal from the inside out.

WARNING

Chemical damage to the unit and / or heat exchanger in any way is not covered under the warranty agreement.

The following are water balance specifications that are considered standard pool and spa water testing values and quality. These water balance values are the industry standard in which professional pool contractors follow. Make sure your pool water is tested and balanced on a weekly basis or more if required. Spas will need extra attention.

See your local pool dealer for help in properly balancing the water chemistry.

SACRIFICIAL WATER FITTINGS

Note: The internal 90˚ elbows show in this diagram are de- signed as a sacrificial fittings to protect the very expensive cu- pronickel alloy heat exchanger.

ADVANCED HEAT EXCHANGER DESIGN

This diagram is a cross section of the heat exchanger. The seam- less tube within another tube design transfers heat very efficiently. The inner water tube is made of thicker resilient cupronickel metal alloy to help resist corrosive pool water. The outer heavy gauge Freon™ tube is dipped in a special weather proofing material.

Then to insulate from heat loss and help prevent exterior corro- sion the heat exchanger is encased in a block of special closed cell foam.

Water Fittings

 

These fittings may develop a leak if the pool water balance gets

 

very acetic or very over chlorinated. If there were no sacrificial

 

fittings, chemical damage could cause a "breach" from the water

 

passage to the refrigerant passage. If a" breach" occurs in the

 

heat exchanger, chlorinated water would be pumped into the re-

 

frigerant system thus making the heater non-repairable! The sac-

 

rificial fittings act as an early warning indicator to the user that

 

the pool water balance is not correct, chemicals are being fed im-

 

properly (through the skimmer) or the flow rate has been exceeded.

 

The sacrificial fittings alert the user before "it's too late"
