SECTION I. GENERAL INFORMATION 7 INTRODUCTION: This manual contains instructions for installation, operation, maintenance, troubleshooting, and parts lists for the safe use of the swimming pool/spa/hot tub heaters. Hayward strongly recommends that the installer read the manual before installing the swimming pool/spa/hot tub heater. If after reviewing the manual any questions remain unanswered, contact the factory or local representative.

LIMITED WARRANTY SUMMARY: Hayward warrants the pool/spa/hot tub heater to be free from defects in materials and workmanship, and will within one year from date of installation for all users, for the original purchaser, repair or, at our option, replace without charge any defective part. Hayward further warrant that if the heat exchanger or exchanger headers (water-containing section) leak within one year from date of such installation for all users, due to defects in materials and workmanship, Hayward will provide a replacement part. Cost of freight, installation, fuel, and service labor (after one year) is at user's expense. For full details of warranty agreement, see warranty certificate included in this manual. ATTENTION: If the pool/spa/hot tub heater is damaged or destroyed by improper maintenance, excessive water hardness, incorrect water chemistry, or freezing it is not covered under the manufacturer's warranty. MAINTAINING PROPER WATER CHEMISTRY: WARNING: Failure to Maintain Proper Water Chemistry May Cause Premature Heat Exchanger Damage or Failure The heat exchanger in your Hayward pool heater is made from the highest quality of copper and nickel (Cupronickel) materials. The premium materials and the exacting processes used in the manufacture of the heat exchanger is state of the art in pool heater design and manufacture. Yet, it remains vital that the heat exchanger be protected from damaging or corrosive chemicals, insufficient water flow or improperly balanced water chemistry. Heat exchanger damage or failure resulting from improper flow, improperly balanced pool water or the improper addition of sanitizers into the water is NOT covered under the terms of your warranty. The following factors are critical to heat exchanger protection. Follow these guidelines to help prevent pre-mature damage or failure to your heater and heat exchanger. 1. WATER FLOW THROUGH HEATER Water must be flowing through the heater at the minimum rated flow rate during operation. Check that the pump is operating and the system is filled with water and purged of all air prior to starting the heater. The minimum rated flow rates are listed on page 26. Some installations may require an adjustment to the water pressure switch for proper low-flow protection. Test your system and if necessary, adjust the water pressure switch as described on page 35.
