Ventilation Methods Hot Air Exhaust; Power Level P-0 To P-90 Cooking - Frigidaire CFMV152KW Servicing Manual

VENTILATION METHODS HOT AIR EXHAUST

1. Vertical Venting
For this venting method, hot air rising from the
conventional range below is drawn in by the hood fan
motor through the grease fi lters at the right and left
sides of the base cover, up through the right and left
sides of the oven cavity, then discharged vertically at rear
center top of the oven, into the customer's vent system.

2. Horizontal Venting
The air handing is the same as Vertical Venting except
that fi nal air discharge is directed horizontally out from
the top rear of oven into the customer's vent system.

3. Re-circulation (Inside venting)
The air handing is the same as VERTICAL VENTING
except that the final air discharge is directed horizontally
through the upper front of the oven into the kitchen. In
this case, the accessory charcoal Filter RK-240 must be
provided to filter the air before it leaves the oven.

POWER LEVEL P-0 TO P-90 COOKING

When Variable Cooking Power is programmed, the
120 volts A.C. is supplied to the power transformer
intermittently through the contacts of relay (RY2) which
is operated by the control unit within an interval second
time base. Microwave power operation is as follows:
Vari-Mode
Power 10 (High) (100% Power) 29 sec.
Power 9 (P-90) (Approx. 90%)
To Duct
Power 8 (P-80) (Approx. 80%)
Power 7 (P-70) (Approx. 70%)
Power 6 (P-60) (Approx. 60%)
Power 5 (P-50) (Approx. 50%)
Power 4 (P-40) (Approx. 40%)
Power 3 (P-30) (Approx. 30%)
Power 2 (P-20) (Approx. 20%)
Power 1 (P-10) (Approx. 10%)
Power 0 (P-0) (0% power)
NOTE
The ON/OFF time ratio does not correspond with
the percentage of microwave power, because
approximately 2 seconds are needed for heating of
the magnetron filament.
