SAFE SERVICING PRACTICES
To avoid the possibility of personal injury and/or
property damage, it is important that safe servicing
practices be observed. The following are examples,
but without limitation, of such practices:
1. Do not attempt a product repair if you have any
doubts as to your ability to complete it in a safe and
satisfactory manner.
2. Before servicing or moving an appliance:
• remove fuse.
• turn off gas supply.
• turn off water supply.
3. Never interfere with the proper operation of any
safety device.
4. USE ONLY REPLACEMENT PARTS CATALOGED
FOR THIS APPLIANCE. SUBSTITUTIONS MAY
DEFEAT COMPLIANCE WITH SAFETY STANDARDS
SET FOR HOME APPLIANCES.
5. GROUNDING: The standard color coding for safety
ground wires is GREEN or GREEN with YELLOW
STRIPES. Ground leads are not to be used as current
carrying conductors.
IT IS EXTREMELY IMPORTANT THAT THE SERVICE
TECHNICIAN RE-ESTABLISH ALL SAFETY GROUNDS
PRIOR TO COMPLETION OF SERVICE. FAILURE TO
DO SO WOULD CREATE A POTENTIAL HAZARD.
6. Prior to returning the product to service
ensure that:
•
all electric, gas, and water connections are
correctly and securely connected.
•
all gas and water connections are tested for
leaks. DO NOT TEST FOR GAS LEAKS WITH A
FLAME.
•
all electrical leads are properly dressed and
secured
away
from
sharp
edges,
high-temperature components and moving
parts.
•
all uninsulated electrical terminals,
connectors, heaters, etc. have adequate spacing
from all metal parts and panels.
•
all safety grounds (both internal and external
to the product) are correctly and securely
connected.
•
all panels are properly and securely
reassembled.
CAUTION!
When servicing a water-using
appliance in a location where the water supply
has not been in use for an extended time (such
as vacation) open the hot water faucet at the
sink and allow the water to run for several
minutes allowing water and accumulated
hydrogen gas to escape. Make sure there are no
open flames (pilots) or cigarettes near the
faucet.
CAUTION
A lightning flash symbol, within a triangle. Is intended
to alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclosure
that may be of sufficient magnitude to constitute a
risk of electric shock to persons.
CAUTION
:
TO REDUCE THE RISK OF
ELECTRIC SHOCK DO NOT REMOVE
COVER OR BACK. DO NOT EXPOSE TO
RAIN OR MOISTURE.
NO USER SERVICABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE
PERSONNEL.
An exclamation point within a triangle is intended to
alert the user to the presence of important operating
and maintenance (servicing) instructions in the
literature accompanying the appliance.

NOT EXPOSE THIS PRODUCT TO RAIN OR
MOISTURE.
