PC Cooling not enough / Ice forming
1. Symptom of the problem
PC less cooling.
2. Cause
Fan motor does not work due to ice forming,
stuck to fan motor area.
Fan motor can’t blow cold air.
Then PC temperature is insufficient.
3. Detail of countermeasure / TI No. : REF 12-02
Protect ice-forming to fan motor areas.
1) Add new insulation plate : Kit Part No. WS-08x100x250MM 1 pcs. to INS. rear of cover coil.
2) Add new insulation plate : Kit Part No. WS-08x100x250MM 1 pcs. to rear side of coil EVP.

Estimate cause
Circulated air from PC doesn’t pass into evaporator, pass on only surface.
Therefore circulated air doesn’t become to dried, then circulated air form FC is provided with humidity and
comes out in fan motor area. This area is very cold, so that humidity in circulated air will become ice and
ice forming.
