d)
Reverse two probes. Controller probe is situated at the left-hand end of the element
plate; the safety thermostat probe at the right (marked with a short length of white
sheathing);
e)
Reinstate the top cover before reconnecting connecting electrical supplies.
Pipe connections are stub flanges to suit 1 1/2" (12kW) nominal bore pipe (uPVC or ABS). If using ABS,
the solvent jointing compound must be suitable for both materials. Reducers may be fitted to suit smaller
pipes. 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. It is advisable that isolation valves are fitted either
side of the heater to allow easy removal of the heater without water loss.
Electrical Installation
a) Check heater label for rating to insure the heater matches your electrical supply.
b)
CHECK ELECTRICAL CONNECTIONS TO ALL COMPONENTS
within the heater for tightness.
These can become loose during shipment and handling.
c) Check components for any moisture, rust, or dust which may have accumulated during shipping, and
clean or dry where necessary.
All pool heaters covered in this manual have integral thermostats, contactors and sequencers where
required.
Wiring diagrams included show internal wiring and required field connections for various models. Consult
your local electrical code for proper wire and conduit sizes, and other local requirements.
Do not connect the pool heater to, or operate at a voltage other than the voltage rated on the heater label.
Wires of adequate size are to be fed from a fused disconnect switch or circuit breaker with an ampere
rating of 125% of the ampere rating shown on heater label. Connect power conductors to the power
distribution block inside the heater. All other internal connections are completed and tested at the factory.
Overcurrent protection must also be provided in the form of a Miniature Circuit Breaker (MCB). Due to
the continuous high load that will be drawn, MCBs should be rated at least 20% higher than of the current
shown below.
