▪
Charge the refrigerant in liquid form. Adding it in gas form may prevent normal
operation.
CAUTION
When the refrigerant charging procedure is done or when pausing, close the valve of
the refrigerant tank immediately. If the valve is NOT closed immediately, remaining
pressure might charge additional refrigerant.
Possible consequence:
Incorrect
refrigerant amount.
1.2.4 Water
If applicable. See the installation manual or installer reference guide of your
application for more information.
NOTICE
Make sure water quality complies with EU directive 98/83 EC.
Avoid damages caused by deposits and corrosion. To prevent corrosion products
and deposits, observe the applicable regulations of technology.
Measures for desalination, softening or hardness stabilization are necessary if the
filling and top-up water have a high total hardness (>3 mmol/l–sum of the calcium
and magnesium concentrations, calculated as calcium carbonate).
Using filling water and top-up water which does NOT meet the stated quality
requirements can cause a considerably reduced service life of the equipment. The
responsibility for this is entirely that of the user.
1.2.5 Electrical
DANGER: RISK OF ELECTROCUTION
▪
Turn OFF all power supply before removing the switch box cover, connecting
electrical wiring or touching electrical parts.
▪
Disconnect the power supply for more than 10 minutes, and measure the voltage
at the terminals of main circuit capacitors or electrical components before
servicing. The voltage MUST be less than 50 V DC before you can touch electrical
components. For the location of the terminals, see the wiring diagram.
▪
Do NOT touch electrical components with wet hands.
▪
Do NOT leave the unit unattended when the service cover is removed.
WARNING
If NOT factory installed, a main switch or other means for disconnection, having a
contact separation in all poles providing full disconnection under overvoltage
category III condition, MUST be installed in the fixed wiring.
