F. Testing
1. Inspect the heat pump before use
a. Ensure the ventilating device and outlets are operating adequately and are not obstructed.
b. It is prohibited to install refrigeration pipe or components in corrosive environment.
c. Inspect all the electrical wiring and earthing connections by referencing the electrical wiring diagram.
d. Double check that the main power isolation switch is off.
e. Inspect the air inlet and outlet vent/s, coil/s and fan/s.
2. Leakage detection notice and method
a. Leakage checks are prohibited in closed area.
b. Any ignition source is prohibited during a leakage inspection. A halide torch (or any other detector
using a naked flame) should not be used.
c. 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 pipes.
d. Vacuumise completely before welding. Welding can only be carried out by professional personnel
in a well-ventilated area.
e. Please stop using the heat pump if gas leakage occurs. Contact Rheem or one of their qualified
service agents.
3. Trial & Start Up
a. The user must “Start” the circulation pump before the heat pump is turned on and “Turn” off the
heat pump before the pump” is stopped, or the unit could be damaged.
b. Before starting the heat pump, check for any water leaks around the plumbing fittings.
c. Set the desired temperature on the heater thermostat, and then switch on the power supply.
d. To protect the heat pump, the unit is equipped with a time lag starting function. The fan will run
for 1 minute before the compressor starts and it will stop running 1 minute after the compressor
stops when the unit switches off.
e. When running the startup trial, check for any abnormal noises and leaks from the unit.
f. Please note that condensation will form at the bottom of the unit when it is running and will leak
from the condensate drain hole if the condensation drainage kit and hose are not fitted.
Condensation is normal during operation.
