Electrical safety checks
The electrical safety checks must be completed before
turning on the electrical supplies to the Air to Water
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
ensure continuity between all pieces of equipment on
the earth conductor.
Insulation resistance test
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.
