Pre-Requisites Before Commissioning; Verification Before Switching On - Ideal Heating ECOMOD AHP60 26 kW Installation And Servicing

AHP60 26/32 kW - Installation, Use and Maintenance

4. PRE-REQUISITES BEFORE COMMISSIONING

4.1. Verification before switching on

• Check that the electrical and hydraulic diagrams of the installation the machine is connected
to are available.
• Check that there are safety valves, filters and the expansion system.
• Ensure that the isolation valves of the hydraulic circuits are open.
• Ensure that the hydraulic circuit is pressurised and that the air has been evacuated.
• Check that all of the hydraulic connectors are fitted correctly and that all of the instructions
on the labels have been followed.
• Ensure that measures have been taken to evacuate the condensation.
• Check that the terminals are connected and attached correctly. Check the order of the
phases, the voltages between each phase and the neutral, then between each phase and the
earth.
• Check if the electrical connections comply with the regulations in force, including 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 / 74
• Power up the unit for at least 12 hours before switching it on, in order
to enable the resistances to heat the compressor casing enough (the
resistances 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.
