Electrical System - Sanyo SPW-W366HH58 Notice D'installation

• Water quality:
- In order for the heat pump to operate under good conditions and provide optimum performance, it is essential to
ensure that the system's water circuit is clean. If the water circuit becomes clogged, this will significantly affect the
machine's performance. The circuit must therefore be cleaned with suitable products in compliance with current
standards as soon as it is installed, both for new and renovation work.
We recommend the use of products which are compatible with all metals and synthetic materials and approved by
official bodies.
Recommendations regarding water quality:
- PH: 6 to 9.
GB
- TH: 10 to 20°F.
- Dry material in suspension: < 2 g/l
- Granulometry: < 0.4 mm
- Chloride: 50 mg/l maximum
- Conductivity: 50 to 500 µS/cm2
- Resistivity: 1 to 10 kΩ
- Fibre: no fibres.
Any disorder which may occur on our machines due to the poor quality of the fluid in the installation will not be
covered by the warranty.

6.2 - CONFIGURATION AND PARAMETERISATION
6.2.1 - AUTO-ADDRESSING OF INDOOR AND OUTDOOR UNITS
• Set the control unit selector to "OFF".
• Turn on the indoor and outdoor units. The unit cycles through an automatic addressing phase when the power is first
turned on. This phase may take 2 to 3 minutes and is indicated by the alternate blinking of LED1 and LED2 on the
outdoor unit card.
When these indicator lights cease blinking, addressing is completed and communication between the indoor and outdoor
unit is established.
Note 1:
The addressing phase is indicated on the screen of the RCS-TM80BG keyboard/display unit (if installed) by the flashing
"SETTING" message.
Note 2:
Should a problem arise during this automatic addressing phase, a new phase can be restarted. To do this, simply
disconnect the power supply for at least 1 minute and when power is restored, press the black "AUTO ADD" button on
the outdoor unit's electronic board.
Meaning of LED1 and LED2 activity on the outdoor unit's board.
= ON steady
= ON blinking
= OFF
