WATER HEATERS EQUIPPED FOR ONE VOLTAGE
ONLY: This water heater is equipped for one type
voltage only. Check the rating plate near the bot-
tom access panel for the correct voltage. DO NOT
use this water heater with any voltage other than

doubts consult your electric company.
ACAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of[
the water heater must be accomplished in such a )
manner that if the tank or any connections should I
leak, the flow of water will not cause damage to the [
structure. For this reason, it is not advisable to install I
the water heater in an attic or upper floor. When
such locations cannot be avoided, a suitable drain
pan should be installed under the water heater.
Drain pans are available at your local hardware
store. Such a drain pan must have a minimum diam-
eter of at least 1'/, inches greater than the water
heater diameter and must be piped to an adequate
drain. Under no circumstances isthe manufacturer to
be held liable for any water damage in connection

The Convertible Lower
Element
The Upper Element, is a conventional 3800 watt element
which only operates at its rated wattage on 240 volts.
(See rating plate on water heater).
The Lower Element of the water heater can be converted
from operation at 3800 watts to 5500 watts on a 240 volt
system.
Read and follow water heater warnings and instructions. If
after reading these instructions in this manual, if you do not
understand any portion, call Maytag Customer Service at
1-800-788-8899 for an authorized servicer.
AWARNING
Before making the conversion to 5500 watts, check
the (1) power supply...must be 240 volts, (2)
wiring...10 gauge AWG @ Type TW, 60oC or equiva-
lent, and (3) Circuit breakers or fusing...capable of
30 amp loading. Also, the installation must conform
with this manual, local codes and electric utility
rules. Failure to comply can result in DEATH, SERI-

NOTE: Whether or not the dement conversion is made the
model rating plate must be marked. Using ahard point ink
