ELECTRIC POOL HEATER
STATIONARY MOUNTING OPTION
Some countries, especially in the European community, require the electric pool heater to be
secured to the ground or to a base in a permanent upright position. Check your local
authorities to determine if there is a regulation in your area regarding above-the-ground
swimming pool electric pool heaters. If yes, then the electric pool heater can be mounted to
a platform using the two holes located in the base. See drawing below.
The electric pool heater can be mounted on a cement base or onto a wooden platform to
prevent accidental falling over. Total assembly must exceed 18kg. The European norm EN
60335-2-41 requires this product be secured to the ground or to a base.
1. The mounting holes are 6.4 mm in diameter and spaced 156 mm apart.
2. Use two bolts and lock nuts with a maximum of 6.4 mm in diameter.
156 mm
POOL CARE AND CHEMICALS
• All pools require care to keep the water clear and hygienically clean. With proper
chemical control, your filter will help attain this objective. Consult your pool supply
dealer for instructions regarding the proper use of chlorine, algaecide and other
chemical agents required for sparkling clear water.
• Keep pool chemicals away from children.
• Do not replenish chemicals in pool while pool is occupied. Skin or eye irritations
could occur.
• Daily pH checking and chemical treatment of the water is very important and can not
be overemphasized. Chlorine, algaecide and maintenance of proper pH levels are
required when filling the pool as well as during the season. Consult your local
swimming pool supply store for instructions.
• The season's first filling of the pool may have brackish water requiring extra water
additives and extra filter changes. Do not allow swimming in pool until the pH level is
balanced. Consult your local swimming pool supply store for instructions.
• Keep spare filter cartridges on hand. Replace cartridges every two weeks.
• Chlorinated water may damage lawns, gardens or shrubbery as children play in the
pool and splash water outside the pool. Lawn areas underneath the pool liner will be
destroyed. Note that some types of grass may grow through the liner but function
is not affected.
