Installation

Note: This installation procedure is for guidance only, and the installer should verify its suitability. Make sure that the solar system is physically installed, manually tested, and ready for controlled operation.

The following safety precautions is strongly recommended:

1.Before attempting to install and operate the unit read this instruction manual carefully.

2.Only suitably qualified personnel should carry out installation and required maintenance.

3.It is recommended that the unit be connected to the power supply via an on/off switch or plug.

4.WARNING: When the unit is connected to the 115-volt power supply and the cover is opened, high voltage circuits will be exposed. When installing the unit, all required connections should be completed and the cover attached to the controller box before turning the power on. Ensure that all connections are secure. If any maintenance work is required isolate the unit from the power supply before removing the cover. Never leave the unit unattended if the cover has been removed and the power supply is connected.

5.Do not exceed unit ratings of 3.15 amps (1/6 HP or 245 Watts).

6.It is advisable to route power cables away from sensor cables.

Sensor installation: Temperature sensors may be installed with fluid lines by mounting in a well or strapping it to the piping directly. For the system to function correctly, it is essential that the sensors are located and installed properly. Sensors must be well insulated in order to

prevent them from being influenced by the ambient temperature.

When used outdoors, water must not enter the immersion sleeves. Exposure to moisture (e.g. condensation) can diffuse through the cast resin and damage the sensor.
