1.2.3. Cautions
W
ARNING
• Only use copper wires.
• All field wiring must be performed in accordance with the wiring diagram and installation manual supplied with the
product.
• If the power cable and lead wires have scratches or deteriorated, be sure to replace them. Damaged cable and wires
may cause an electrical shock, excessive heat generation or fire.
• Secure all terminal connections and provide proper routing for cables, both inside and outside the switchbox.
• NEVER squeeze bundled cables and make sure they do not come in contact with the piping and sharp edges.
• Make sure no external pressure is applied to the terminal connections.
• Make sure to check the earth wiring. Do NOT earth the unit to a utility pipe, surge absorber, or telephone earth.
Improper earth wiring may cause electrical shock.
• Make sure to use a dedicated power circuit. NEVER use a power supply shared by another appliance.
• Make sure to check the required fuses and/or circuit breakers before starting works.
W
ARNING
• After finishing the electrical work, confirm that each electrical component and terminal inside the electrical
components box is connected securely.
• Make sure all covers are closed before starting the unit again.
W
ARNING
• The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician
is aware of potentially toxic or flammable atmospheres.
• Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i.e.
non-sparking, adequately sealed or intrinsically safe.
W
ARNING
• Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant.
• The label shall be dated and signed.
• For appliances containing flammable refrigerants, ensure that there are labels on the equipment stating the
equipment contains flammable refrigerant.
C
AUTION
Provide adequate measures to prevent that the unit can be used as a shelter by small animals. Small animals that make
contact with electrical parts can cause malfunctions, smoke or fire.
C
AUTION
• Make sure water quality complies with EU directive 98/83 EC.
• Check the system for leaks after each repair/modification of the water side.
• Check drainage system(s) after repairs.
• Be careful when tilting units as water may leak.
