GENERAL INSTALLATION INSTRUCTION 2.1 Mounting instruction The heater should be either installed horizontally or vertically allowing enough space for the pipe connections and wiring.
2.2 Pipe work The heater should be installed at a low point in the filtration system. It should be positioned downstream of (after) the filter and upstream of (before) any dosing or other water treatment plan. (see Fig 3.). Fig 3. 2.3 Flow direction The heater can accept flow of water from only one end (please refer to flow direction labels on the products).
• The power supply must be fitted with a 30mA RCD. If required, the Electrician may replace the cable entry gland supplied with a larger size to secure the cable powering the heater. Minimum cable sectional area This should be calculated at 5-amp/mm for distances up to 20 metres (these sections are indicative and should be checked and adapted if necessary, for cable lengths over 20 metres).
3. OPERATING INSTRUCTIONS 3.1 Flow requirements The heater should be connected to a filtration system with a minimum flow volume of 12,000-litres per hour (2,640 UK gallons per hour). The maximum flow volume that the heater will operate with is 40,000- litres per hour (8,800 UK gallons per hour).
3.3 Digital touchscreen heater overview The Touchscreen digital heater has been pre-programmed with all the necessary parameters to ensure reliable service & operation. Below is an overview indicating the heater button keys and graphical symbols. On initial power up of the heater the digital display will be illuminated. The heating device will only be switched ‘On’...

In this mode the heater will only heat during a timed-on period and when receiving sufficient flow. If no or insufficient flow is being received no heating will take place. When in a timed off period no heating will take place. Temperature Display Mode Select your required temperature (described earlier in this booklet).
Once the ‘Priority of Heating’ feature has been enabled the heater will take a water temperature sample every hour and the message ‘SAMPLING’ will be displayed. If the pool water temperature is below the required temperature, the heater will send a signal to the heating device to come on until the required temperature is reached.
the first reading from the second reading the number of units (kilo Watts kW) consumed can be calculated. Note that your heater is also rated in kW hours. The pool pump and heater will need to be running continuously during the test. To avoid inaccurate results when performing this test, it is important to refrain from using other high current consuming appliances in the property, such as tumble dryers, showers, cookers etc.

Insufficient flow. - if this is the cause the display will show ‘No Flow’. Possible cause 3: If using a cartridge filter: Confirm this by running the system with the cartridge removed from your pump & filter unit, this will supply the heater with the maximum flow rate that your unit is capable of.
5. MAINTENANCE We recommend annual maintenance and cleaning of the heater to ensure proper operation. WARNING: Before performing any maintenance on the unit isolate from the main power supply. The heater should be drained, the flow tubes and heating elements should be cleaned. Removing scale/sludge and any debris or blockages will extend life expectancy of the heating element(s) and avoid potential failures.
