Chemical Vapors
Spa maintenance chemicals may produce vapors harmful to your C-SPA-XI. Never store chemicals or any flammables near your spa heater. Destruction of the
heater by corrosion or a fire can result.
High Limit
In case of overheating, your C-SPA-XI heater will shut itself off. This is accomplished by the use of a manual reset high limit. To place the heater back in op-
eration, reset the limit per the label instructions on the heater. If the high limit trips again, turn the main heater breaker off and contact your installing dealer,
factory authorized service center or Hayward Pool Products.
Water Flow
Your C-SPA-XI must have an adequate flow of water for proper operation. (See installation and start up procedures). Adequate water flow removes the heat
produced by the heater, transfer the heat to the spa, and prevents overheating. Low water flow usually results form a dirty filter or improperly adjusted
manual by-pass. Manual by-pass valves should be set so that the outlet thermometer reads 6-8°F above the spa water after five (5) minutes of heater opera-
tion.
The recommended minimum flow through the heater is 12 GPM (gallons per minute) up to a maximum flow of 60 GPM. If flow exceeds 60 GPM, refer to the
diagram on page 5 and install an external by-pass.
