2. Size fuses or circuit breaker has been installed at the main switchboard.

3. Supply voltages as specified on unit wiring diagram.

4. All cables are properly identified and tight connected at the unit.

5. the cables and wires are clear of or protected from pipework and sharp edges.

14.1.2. HYDRAULIC CHECK

1. Check that the external water circuit components (pumps, user equipment, filters, 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 hydraulic circuit is filled correctly and that the fluid flows freely without any signs of leaks

or air bubbles. When ethylene glycol anti-freeze is used, check that the concentration level is correct.

3. Check that the condensates drainage pipe is properly attached and free of any blockages.

4. Carry out the usual checks on the main water loop and particularly to ensure that the water circulation

pump operates correctly.

Non-compliance with this rule may result in irreversible damage to the plate exchanger.

In addition, we recommend the use of a flow controller on the units' inlet pipe (not

supplied).

5. Adjust the water flow in order to comply with the specifications.

6. Check that the water quality complies with the indicated standards.

1. Rotate the fan by hand to ensure that it turns freely and that the fan turbine is properly attached to

the motor shaft.

2. Ensure that the finned heat exchanger surfaces are clean. Clean if required.

3. Check the correct positioning of the filters and that they a clean and accessible.

4. Clearances around unit including outdoor air entry and discharge openings and service accesses.

5. Unit mounted as specified.

6. For loose or missing bolts or screws.

1. Before the first start-up the compressor transport clamping be removed. Failure to do this

could result in vibrations, high noise and could lead to the refrigerant tubes breaking.

2. Before attempting any start-up, ensure that the air and water temperatures are within the appliance's

operating limits (Refer to the § OPERATING LIMITS, page 6).

3. Ensure that no Alarm code is displayed when the mains power supply is switched on (Refer to the

"Alarm code" chart).
