The appliance is operated under the conditions in Clause 11 at rated voltage or at the upper limit of the rated voltage range, at an ambient temperature of 23?C ? 5?C. When steady conditions are attained, the heat transfer medium flow of the outdoor heat exchanger is restricted or shut off, whichever is the most unfavourable without the appliance being non-operative.
After this test, protective devices that may operated are reset, and the test is repeated, with the heat transfer medium flow, fluid or air, of the indoor heat exchanger, restricted or shut off, whichever is the most unfavorable without the appliance being non-operative. In the case of appliances with defrosting systems, the transfer medium flow rate is additionally shut off at the beginning of the defrosting phase.
Appliances incorporating a motor common to both the indoor and outdoor heat exchangers are subject to the above test, the motor being disconnected once steady conditions are attained. |
