Fouling Factors - Haier AU082FYCRA(HW) Service Manual

Note:
1. During winter leaving the unit unused, please drain water out completely from unit if no anti-freeze were charged
into pipeline, or keep power on (at standby or off status) and ensure that water is contained inside of unit.
2. When ambient temperature lower 5, running cooling mode must be charged antifreeze. Refers to upper
parameters for the charged volume.
b) Fouling Factors
The performance data given refer to conditions with clean evaporator plates (fouling factor=1). For different fouling
factors, multiply the figures in the performance tables by the coefficient given in the following table.
