Zenith Range Instruction Manual Introduction The Thermalec Zenith heater is designed for use with swimming pools, spas and other similar installations. To prevent damage to the heater it must not be operated unless it is fully flooded with a sufficient flow of pool water.
Zenith Range Instruction Manual Location The protection rating of the heater is lP21 and it should be installed in a weatherproof enclosure with good drainage. A suitable anti-condensation heater should be provided in high ambient humidity conditions, since moisture can damage electrical components. The heater must be installed in a cool, dry location.
It is not necessary to fit unions either side of the heater as the stub flanges are easily disconnected from the heater, by removing the nuts securing the aluminium backing flanges to the heater. In very tight installations, the studs themselves may be unscrewed. Figure 3 Water connection on a Thermalec® pool heater Page 11...
