14. COMMISSIONING
14.1. PRE-START CHECK LIST
1. Electrical installation has been carried out according to unit wiring diagram and the Supply Authority
Regulations in effect.
2. Size fuses or circuit breaker has been installed at the main switchboard.
3. Supply voltages as specied on unit wiring diagram.
4. Check that all of the appliance’s electrical connections have been tightened.
5. Check that the electric motors are planned for the network supply voltage.
6. the cables and wires are clear of or protected from pipework and sharp edges.
7. Check the electrical grounding of the appliance.
1. Check that the external water circuit components (pumps, user equipment, lters, expansion tank
and reservoir if supplied) have been correctly installed in accordance with the manufacturer’s
recommendations and that the water inlet and outlet connections are correct.
2. Check that the water quality complies with the indicated standards (Refer to the § WATER QUALITY,
page 17).
3. Check that venting and draining caps are properly closed.
4. Check the presence, direction and position of the water lter upstream of the appliance (mailles ≤
800µm).
5. Check the presence and position of the stop valves to isolate the unit during maintenance periods.
6. Check that the hydraulic circuit is lled correctly and that the uid ows freely without any signs of
leaks or air bubbles. When glycol anti-freeze is used, check that the concentration level is correct.
7. Check that the pump liners are not stuck. The shaft of the motor must turn freely "by hand". If
necessary, free up the shaft using a tool.
8. Check the direction of rotation of the pump and leave the uid to circulate for at least 12 hours for
each pump. Then clean the pump inlet water lter.
9. Adjust the water ow in order to comply with the specications.
1. Check the lack of debris or cardboard in the unit.
2. Check free clearances around the unit :
 exchanger air intake
 exchanger air outlet
 access or maintenance work.
3. Unit mounted as specied.
4. Check that the unit is level and that condensates drain freely away from the unit (pouHeat pump
units).
5. Check that there is no possibility of blown air being recycled through the fans due to wind exposure.
6. In arduous climates (sub-zero temperature, snow, high humidity), check that the appliance is raised
10 cm off ground.
7. For loose or missing bolts or screws.
8. For refrigerant leaks in connections and components.
Before commissioning the system, you must carry out a certain number of installation checks to ensure that
the appliance will operate in the best possible conditions. The following list of checks is not exhaustive and
only serves as a minimum reference guide.
14.1.1. VISUAL CHECK
14.1.2. ELECTRICAL CHECK
14.1.3. HYDRAULIC CHECK
1. Check that the oil heating resistances have been energised for at least 12 hours.
