6. TESTING
6.1 Inspect heat pump before use
a. Ensure the ventilation is adequate and there are no obstructions.
b. Ensure your Davey heat pump is not close to any corrosive substances.
c. Verify that the electrical wiring has been completed as per instructions.
6.2 Leakage detection notice and method
a. Keep away from any sources of ignition. A halide torch
(or any other detector using a naked flame) shall not be used.
b. Leakage detection fluids can be applied with most refrigerants but the use of detergents containing
chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe.
c. If a gas leak occurs, cease operation and contact a Davey service centre.
6.3 Trial
a. Your water circulation pump must be running before your Davey heat pump starts and needs to continue
running until after your heat pump stops. This will avoid damage to your heat pump.
