4. PRE-REQUISITES BEFORE COMMISSIONING

4.1. Verification before switching on

• Check that the electrical and hydraulic diagrams of the installation the machine is connect-
ed to are available.
• Ensure that the isolation valves of the hydraulic circuits are open.
• Check that there are safety valves filters and expansion systems.
• Ensure that the hydraulic circuit is filled, pressurised and bled.
• Check that all of the hydraulic connectors are fitted correctly and that all of the instructions
on the labels have been followed.
• Check that the hydraulic installation is in accordance with the diagram included in the Eco-
mod Heat Control regulation instructions.
• Ensure that arrangements have been made to evacuate the condensation.
• Check that the terminals are connected and attached correctly.
• Check if the electrical connections comply with the regulations in force, including the
earth.
• Check the order of the phases, the voltages between each phase and the neutral, then
between each phase and the earth.
• The voltage must be the same as that stated on the appliance's rating plate.
• Ensure that the voltage is definitive and within the tolerance limits (±5%).
• Before switching on, check if all of the cover panels have been fitted and attached with the
appropriate screws.
CAUTION:
44 / 78
• Power up the heat pump at least 12 hours before switching it on, in
order to enable the resistors to heat the compressor casing enough
(the resistors are automatically supplied when the switch is closed).
The heating elements are operating correctly if after a few minutes the
temperature of the compressor housing resistor is 10 to 15°C hotter
than the ambient temperature.
• Check that the weight of the pipes is not resting on the machine
structure.
• Stop the appliance temporarily, do not switch off the power supply
using the main isolator switch; this operation must only be used to
switch off the electrical power supply to the appliance for prolonged
stoppages (for example, seasonal holidays, etc.). Furthermore, the
absence of the voltage means that the housing resistors are no longer
powered and that there is a risk of compressor failure when the unit is
switched back on.
• Do not modify the electrical connections of the appliance, otherwise
this will nullify the warranty immediately.
