KitchenAid KEHU309SSS03 Installation Instructions Manual page 4

A cold water supply with water pressure between 30 and 120 psi
(207 and 827 kPa) is required to operate the steam feature. In
Massachusetts, plumbing code 248 CMR 3.00 and 10.00 must
be followed. If you have questions about your water pressure call
a licensed, qualified plumber.
Reverse Osmosis Water Supply
IMPORTANT: The pressure of the water supply coming out of a
reverse osmosis system going to the water inlet valve of the oven
needs to be between 30 and 120 psi (207 and 827 kPa).
If a reverse osmosis water filtration system is connected to your
cold water supply, the water pressure to the reverse osmosis
system needs to be a minimum of 40 psi (276 kPa).
If the water pressure to the reverse osmosis system is less than
40 psi (276 kPa):
• Check to see whether the sediment filter in the reverse
osmosis system is blocked. Replace the filter if necessary.
• Allow the storage tank on the reverse osmosis system to refill
after heavy usage.
If you have questions about your water pressure, call a licensed,
qualified plumber.
If codes permit and a separate ground wire is used, it is
recommended that a qualified electrical installer determine that
the ground path and the wire gauge are in accordance with local
codes.
Check with a qualified electrical installer if you are not sure the
oven is properly grounded.
This oven must be connected to a grounded metal, permanent
wiring system.
Be sure that the electrical connection and wire size are adequate
and in conformance with the National Electrical Code, ANSI/
NFPA 70-latest edition or CSA Standards C22.1-94, Canadian
Electrical Code, Part 1 and C22.2 No. O-M91-1atest edition, and
all local codes and ordinances.
A copy of the above code standards can be obtained from:

Electrical Connection
To properly install your oven, you must determine the type of
electrical connection you will be using and follow the instructions
provided for it here.
• Oven must be connected to the proper electrical voltage and
frequency as specified on the model/serial number rating
plate. The model/serial number rating plate is located at the
bottom of the right-hand mounting rail. See the following
illustration.
A
A. Model/serial number plate
Models rated from 7.3 to 9.6 kW at 240 volts (5.5 to 7.2 kW
at 208 volts) require a separate 50-amp circuit. Models rated
at 7.2 kW and below at 240 volts (5.4 kW and below at
208 volts) require a separate 30-amp circuit.
A circuit breaker is recommended.
Connect directly to the circuit breaker box (or fused
disconnect) through flexible, armored or nonmetallic
sheathed, copper cable (with grounding wire). See "Make
Electrical Connection" section.
Flexible conduit from the oven should be connected directly
to the junction box.
Do not cut the conduit. The length of conduit provided is for
serviceability of the oven.
A UL listed or CSA approved conduit connector must be
provided.
If the house has aluminum wiring follow the procedure below:
1. Connect a section of solid copper wire to the pigtail
leads.
2. Connect the aluminum wiring to the added section of
copper wire using special connectors and/or tools
designed and UL listed for joining copper to aluminum.
Follow the electrical connector manufacturer's recommended
procedure. Aluminum/copper connection must conform with
local codes and industry accepted wiring practices.
