Ventilation Requirements
The Wavejet Microwave requires unobstructed air at the rear inlets at an inlet air
temperature not exceeding 35
°
C. The unit dissipates approximately 500 watts of
heat via two 3-inch diameter fans located in the top rear portion of the unit. Cool air
is drawn into the two ports located in the top rear of the unit and warm air is ejected
out the ports located in the lower portion of the unit. For proper cooling of the
microwave oven, it is strongly recommended to prevent the mixing of the cool inlet
air with the warm exhaust air. The unit has its own fans but they must have a fresh
air supply and a way to exhaust the warm air. There are three ways to do this:
1. Provide a space around the unit that is separated top to bottom with a
piece of foam or rubber (baffle) that allows the air to come in the top and
go out the bottom. Figure 2 shows the suggested installation to properly
channel the air using baffles.
2. Provide an intake at the rear and at the top of the cavity plus an exhaust
at the rear bottom. Both to be approximately 10 to 14 inches
