COMMISSIONING THE HEAT PUMP
7.3.1.
ON-SITE COMMISSIONING REQUIREMENTS
Before the heat pump can be commissioned, the following prerequisites must be fulfilled by the customer:
1. Electrical connections have been made in accordance with local public utility regulations, including
the necessary fuses.
2. The electrical wiring between the on-site components, including the data line, has been fully and
continuously produced.
3. The heat pump is connected on the sink side. Strainer and pipe network are installed. The con-
nected circuits are filled and vented.
4. Signal lines for fault signal and external release have been routed and connected accordingly.
5. General basic requirements at the installation site such as sufficient lighting, power supply, accessi-
bility, etc., are guaranteed.
6. External services that must be provided by other specialist companies must be available during
commissioning.
7. Sufficient heating load (min. 50%) is permanently available during installation to enable the heat
pump and its safety device to be checked.
8. Information on the adjacent hydraulic losses of the hot water pipeline is available.
7.3.2.
INDIVIDUAL STEPS TO BE COMPLETED DURING COMMISSIONING
1. System check (visual inspection), e.g. checking on-site services, etc.
2. Check the factory-set control parameters and adjust to local conditions.
3. Connect external release lines and sensors.
4. Connect the potential-free fault signal (output 13, terminal strip X1) to the BMS.
5. Electrical test of the supply, control and electrically operated safety devices in dry operation (without
compressor operation).
6. Refrigeration test of safety devices such as high-pressure/low-pressure devices.
7. Start up the heat pump and log the measured data (temperatures, pressures, power consumption of
all consumers).
8. Leak test according to Regulation (EC) No. 842/2006 of the cooling circuit(s) by means of suitable
measuring instruments or suitable measuring methods. Document the inspection.
9. Testing the functionality of the smoke detector and bypass damper
10. Adjusting the constant-pressure-controlled exhaust fan
11. Instruct the operator or a representative. Instruction is given with regard to the operation of the unit,
the function of the safety devices and the behaviour in the event of accidents or faults.
