Sharp R1870 Ation Instruction Manual

							
2WALL CONSTRUCTION
This Microwave Oven/Hood should be mounted against and sup
ported by a flat vertical wall. The wall must be flat for proper
installation. If the wall is not flat, use spacers to fill in the gaps.
Wall construction should be a minimum of 2 x 4 wood studding
and
3/8or more thick dry wall or plaster/lath. The mounting sur
faces must be capable of supporting weight of 110 pounds—the
oven and contents—AND the weight of all items which would nor
mally be stored in the top cabinet above the unit.
The unit should be attached to a minimum of one 2 x 4 wall stud.
To find the location of the studs, one of the following methods may
be used:
A. Use a stud finder
,a magnetic device which locates the nails in
the stud.
B. Use a hammer to tap lightly across the mounting surface to find
asolid sound.  This will indicate stud location. 
The center of the stud can be located by probing the wall with a
small nail to find the edges of the stud and then placing a mark
halfway between the edges. The center of any adjacent studs will
normally be 16 or 24 to either side of this mark.
NOTE:In the event that the unit will be unable to be supported by any stud, i\
t will be necessary to use spe 
cial care in the placement of the toggle bolts and top cabinet screws. S\
ee Wall Template for details. The top
cabinet should be tested to ensure it is securely attached to the wall. \
Place extra weight up to 110 pounds
inside the top cabinet to test the support.

INSTALLATION INSTRUCTIONS
P lease read all instructions thoroughly before installing the Microwave O\
ven/Hood System. Two people are
recommended to install this product.
If a new electrical outlet is required, its installation should be compl\
eted by a qualified electrician before the
Microwave Oven/Hood is installed. See 3 ELECTRICAL GROUNDING INSTRUCTIONS on page 2.
1 MOUNTING SPACE
This Microwave Oven/Hood requires a mounting space on a wall
as shown in Figure 1.   
If the space between the wall cabinets is greater than 30inches
(36inches or 42inches), a Filler Panel Kit may be used to fill the
gap between the Microwave Oven/Hood system and wall cabi
nets. The Filler Panel Kit is sold as an optional accessory; each
kit contains two 3inch panels.  The Filler Panel Kit should be
installed before the Microwave Oven/Hood is installed.
For proper installation and servicing, a 2inch space is necessary
between the top of the range backsplash and the bottom of the
Microwave Oven/Hood system.

							3 ELECTRICAL GROUNDING INSTRUCTIONS
This appliance must be grounded. This oven is equipped with a cord having a grounding wire with a ground
ing 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, ground
ing reduces risk of electric shock by providing an escape wire for the electric current.
WARNINGImproper use of the grounding plug can result in a risk of electric shock.
The oven is equipped with a 3prong 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/Hood
mounting location.
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 dam
age to the oven or personal injury resulting from failure to
observe the correct electrical connection procedures.

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 31/4 x 10 rectangular
duct. If round duct is required, a rectangulartoround 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 31/4X 10 rectangular or 6
diameter round duct should not exceed 140 feet.
Elbows, adapters, wall, roof caps, etc. present addi
tional resistance to air flow and are equivalent to
asection 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 4 shows the approximate feet of
equivalent length of some typical ductwork parts.
Use the values in parentheses for calculating air
flow resistance equivalent, which should total less
than 140 feet.
5TOOLS RECOMMENDED FOR INSTALLATION
•Phillips Screwdriver • 11/2 Wood Bit or Metal Hole Cutter (if metal cabinet is used)
•Electric Drill •
