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 the one shown on the model rating plate. Failure to use the correct voltage can cause problems which

can result in DEATH. SERIOUS BODILY INJURY. OR

PROPERTY DAMAGE. If you have any questions or

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 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
