4 Commissioning
4.1 Prerequisites for commissioning
Installation, commissioning, or service of the appliance is to be carried
out by authorized and trained personnel only, adhering to all local
regulations and requirements.
The person commissioning the system must:
● have qualification and competence for installing high pressure devices
● have expert knowledge about heating and cooling systems
● be familiar with the heat pump control system
It is recommended that an Oilon expert performs commissioning.
Tasks to be completed before commissioning:
● connect the electrical supply to the heat pump
● fill and vent the pipe lines
● connect the feed cables and sensors
● connect the safety valve pipeline to outside air
● check the refrigerant level
● connect the pipings correctly according to the PI diagram or according to the
instructions in section
Installation site requirements
.
● check that the shut-off valve of the liquid line open.
In low ambient temperatures, to avoid freezing, liquid systems should be protected
using insulation tape, trace heating cables and a suitable antifreeze liquid. To make
sure that the liquid circulates, when the ambient temperature is close to the freezing
point, pumps must be used. Also heat exchanger nozzles must be insulated.
Do not touch any liquid without protection. Operating liquid contact
may cause frostbite. Always immediately inform operating staff about
leakage.
Before commissioning, check that the shut-off valve of the liquid line is
open.
Do not start any circulation pumps before the circuits have been filled.
Otherwise pump shaft seal gets damaged.
