heat pump system. The electrical safety checks should
be completed by a qualified electrician. All results
measured should comply with your local/national
electrical installation regulations.
Earth continuity test
On completion of the electrical installation a resistance
test should be completed on the earth conductor to

This test must be completed using a 500 V D.C.
insulation resistance tester. Insulation resistance tests
should be completed between each live terminal and
earth.
