14 Start-up checklist

14 Start-up checklist
Check the following checklist before putting the heat
pump into service. Only operate the heat pump when all
points have been satisfied in essence.
Heating circuit checklist
During planning, was consideration given to parts of the building
that are to be heated at a later time?
Was the power for the hot water supply considered?
Were the heating circuits in the system hydraulically balanced?
Were leakage pressures determined by pipe network calculations?
If planning calculations showed that pressure losses were to be
expected: Was a second pump incorporated to overcome the
pressure losses?
Have you taken the minimum mass flow of the heat pump into
consideration?
Was a dirt filter incorporated in the return line?
Was the system provided with all the safety devices described in
this manual?
Were an overflow funnel and blow-out line incorporated?
Were the pipes insulated with thermal insulation?
Was the heating circuit flushed, filled and bled?
Was the heating circuit checked for leaks?
Brine circuit checklist
Was the brine circuit pressure tested with water and checked for
leaks?
Were the water/antifreeze mixing proportions
(2:1) adhered to?
Was the frost protection (-15 °C) tested with a frost protection
tester?
Was a pressure switch incorporated in the brine circuit?
Was the pressure switch connected to the heat pump?
Was a dirt filter fitted at the brine side input to the heat pump?
Were stop valves incorporated into the brine circuit?
Were pressure regulating valves incorporated into the brine
circuit?
Were the brine circuits hydraulically balanced?
Was the brine expansion tank fitted?
Was the brine source circuit filled to a pressure of 1.5 bar?
Was the brine expansion tank filled to 2/3 full?
Were isolating devices fitted ahead of the heat pump?
Were the pipes thermally insulated against vapour diffusion?
