8 Commissioning
The heat pump controller must be configured for the heating system before the commissioning.
The description of the control system and the manual for its setting is in a separate document
supplied with the heat pump. Further, the system must be inspected per following items.
8.1 Mechanical Installation Inspection
•
suitable unit location inside/outside if the building
8.2 Piping Network Inspection
•
inspection of pressure and leak test according to local regulations
•
safety equipment complies with local regulations and standards, between safety valve
and heating equipment must not be any closing armature
•
dimension inspection of piping on the side of the ground loop and the heating system,
flow speed must not exceed 1m/s for connection length of up to 3m, in the case
connection of up to 10m the speed must not exceed 0,6m/s. In the case the connection is
longer, hydraulic resistance of external pressure of circulation pumps used or circulation
pumps inside the heat pump unit must be surveyed
•
liquid circuits pressure inspection
•
gas filling of expansion vessels inspection
•
filters on the unit inlet
•
heating circuit inspection
•
ground loop venting inspection, liquid must flow through all loops, inspection by closing
the ball valve of each loop – immediately before closing a strong hydraulic noise is heard
•
inspection of mixing of anti-freeze mixture by closing one loop at a time for half the time
required for a full circle of the entire volume of anti-freeze mixture
•
flow sensor inspection, or modification of its setting
•
inspection of hydraulic connection – preventing the hot heating water from entering the
heat pump, typically from gas boilers and solid fuel boilers
8.3 Electrical wiring check
•
inspection of initial revision of electric connection
•
dimensioning of main switchboard and supply cable
•
inspection of setting and operation of operating thermostats of bivalent sources in
relation to heat pump operating requirements
•
inspection of emergency thermostats with manual reset under the cover which is difficult
to remove, typically for electric radiators located in accumulation reservoirs
•
inspection of correct phasing
•
presence of current guard, in the case outer electric components are installed
•
inspection of connection and switching of tariff control
8.4 Start-up and Filling of Start-up Protocol
It is allowed to start-up the heat pump after the inspection. Data is filled in the Start-up Protocol
and the Service Book after stabilization of operating parameters. The Start-up Protocol and the
Service Book are supplied with the heat pump.
