14. Commissioning

Thorough safety precautions shall always be taken when performing startup and service.
CAUTION
Only qualifi ed individuals should perform these functions.

14.1. Pre-start check list

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.
1. Check that the equipment installed matches the order
2. Check that the crankcase heaters have been energised for at least 12 hours.
14.1.1. Visual check
1. Check for 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 specifi ed.
4. Check that the unit is level and that condensates drain freely away from the unit (applicable to heating operation only).
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 ≥100mm above the
ground or supporting structure.
7. For loose or missing bolts or screws.
8. For refrigerant leaks in connections and components.
14.1.2. Electrical check
1. Electrical installation has been carried out according to unit wiring diagram and the Supply Authority Regulations are in
effect.
2. Correctly sized fuses or circuit breakers have been installed at the main switchboard.
3. Supply voltages as specifi 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 suitable 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.
14.1.3. Hydraulic check
1. Check that the external water circuit components (pumps, user equipment, fi 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 19).
3. Check that venting and draining caps are properly closed.
4. Check the presence, direction and position of the supplied water, fi lter upstream of the appliance (mesh ≤ 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 fi lled correctly and that the fl uid fl ows freely without any signs of leaks or air bubbles.
When ethylene 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 fl uid to circulate for at least 12 hours for each pump. Then clean
the pump inlet water fi lter.
9. Adjust the water fl ow in order to comply with the specifi cations.
