4 HOOD EXHAUST DUCT
When the hood is vented to the outside, a hood exhaust duct is required. All ductwork must be metal; absolutely do
not use plastic duct. Check that all connections are made securely. Please read the following carefully:
Exhaust connection:
The hood exhaust has been designed to connect to a standard 3-1/4” X 10” rectangular
duct. If round duct is required, a rectangular-to-round adapter must be used.
Rear exhaust:
If a rear or horizontal exhaust is to be used, care should be taken to align the exhaust with the
space between the studs, or wall should be prepared at the time it is constructed by leaving enough space
between wall studs to accommodate exhaust.
Maximum duct length:
For satisfactory air movement, the total duct length of 3-1/4” X 10” rectangular or 6”
diameter round duct should not exceed 140 feet.
Elbows, adapters, wall caps, roof caps, etc. present
additional resistance to air flow and are equivalent to a
section of straight duct which is longer than their actual
physical size. When calculating the total length, add
the equivalent lengths of all transitions and adapters
plus the length of all straight duct sections. Figure 3
shows the approximate feet of equivalent length of
some typical ductwork parts. Use the values in paren-
theses for calculating air flow resistance equivalent,
which should total less than 140 feet.

3 ELECTRICAL GROUNDING INSTRUCTIONS
This appliance must be grounded. This oven is equipped with a cord having a grounding wire with a grounding plug.
It must be plugged into a wall receptacle that is properly installed and grounded in accordance with the National
Electrical Code and local codes and ordinances. In the event of an electrical short circuit, grounding reduces risk of
electric shock by providing an escape wire for the electric current.
WARNING
-
Improper use of the grounding plug can result in a risk of electric shock.
Electrical Requirements
The oven is equipped with a 3-prong grounding plug. DO NOT UNDER ANY
CIRCUMSTANCES CUT OR REMOVE THE GROUNDING PIN FROM THE PLUG.
The Power Supply Cord and plug must be connected to a separate 120 Volt AC, 60
Hz, 15 Amp, or more branch circuit, single grounded receptacle. The receptacle
should be located inside the cabinet directly above the Microwave Oven mounting
location as shown in Figure 2.
NOTE:
1. If you have any questions about the grounding or electrical
instructions, consult a qualified electrician or serviceperson.
2. Neither Sharp nor the dealer can accept any liability for
damage to the oven or personal injury resulting from failure to
observe the correct electrical connection procedures.
Radio or TV Interference
Should there be any interference caused by the microwave oven
to your radio or TV, check that the microwave oven is on a
different electrical circuit, relocate the radio or TV as far away from
the oven as feasible or check position and signal of
receiving antenna.
