2.2 Installation and connections
Install the unit outside as you can see on page 27.
The Sun Spring heat pumps are designed and constructed to provide long performance life when in-
stalled and operated properly under normal conditions. Periodic inspections are important to keep your
heat pump running safely and efficiently through the years.
The following basic guidelines are suggested for your inspection:
•
Make sure the front of the unit is accessible for future service.
•
Keep the surrounding areas of the heat pump clear of all debris.
•
Keep all plants and shrubs trimmed and away from the heat pump.
•
Keep lawn sprinkler heads from spraying on the heat pump to prevent corrosion
and damage. Use a deflector if needed.
•
If the unit is installed under a very sharp roof pitch or under a roof without a gutter, a gutter
or diverter should be fitted to prevent excessive water from pouring down onto the unit.
•
Do not use the heat pump if any part has been under water. Immediately call a qualified
professional technician to inspect the heat pump and replace any part of the control system,
which has been submerged.
2.3 Water connections
The piping to and from the heat pump need to have a 50mm outer diameter and need to be glued or
clamed onto the water connections that came with the heat pump.
These pipes can be hard PVC or flexible. Always install piping intended for swimming pool use and
use the correct glue to put them together.
2.4 Electrical connection
Always check if the voltage from the network corresponds with the operating voltage of the unit.
The heat pump must only operate together with the filter pump. Both should always be powered
together. Therefore, connect them to the same circuit breaker type D. The heat pump will get dama-
ged when operated without water flow and will void warranty.
Please adhere to the following guidelines for the rest of the electrical installation:

Attention: Ensure good grounding
The heat pump is supplied with a connection cable and can
be plugged directly into an outlet. The cable has standard a 30mA RCD.
Attention: test the RCD before usage as follows:
1. Plug the RCD into a fixed socket
2. Press the “RESET” button. The indicator should be “ON”.
3. Press the “TEST” button. The indicator should be “OFF”.
4. Press the “RESET” button again to start using the heat pump.
You should always switch off the heat pump immediately when the RCD indicator is turned “OFF”.
Be extremely careful when pressing “RESET” after a failure because there might still be a problem.
