Water Piping
HOTTER WATER CAN SCALD: Water heaters are intended to
produce hot water. Water heated to a temperature which will
satisfy clothes washing, dish washing, and other sanitizing
needs can scald and permanently injure you upon contact.
Some people are more likely to be permanently injured by hot
water than others. These include the elderly, children, the infirm,
or physically/mentally handicapped. If anyone using hot water
in your home fits into one of these groups or if there is a local
code or state law requiring a certain temperature water at the
hot water tap, then you must take special precautions. In
addition to using the lowest possible temperature setting that
satisfies your hot water needs, a means such as a mixing
valve, shall be used at the hot water taps used by these people
or at the water heater. Mixing valves are available at plumbing
supply or hardware stores. Follow manufacturers instructions
for installation of the valves. Before changing the factory setting
on the thermostat, read the “Temperature Regulation” section
in this manual.
See Figure 8 on page 9 for mixing valve usage.
Figure 9 shows the attachment of the water piping to the water
heater. The water heater is equipped with 3/4” water
connections.
If a water heater is installed in a closed water supply system;
such as one having a back-flow preventer, check valve, water
meter with a check valve, etc... in the cold water supply; means
must be provided to control thermal expansion. Contact the
local utility or call Maytag Customer Service at 1-800-788-
8899 for an authorized servicer on how to control this
situation.
NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adapter to the water inlet connection.
Do not solder the water supply lines directly to the cold water
inlet. It will harm the dip tube and damage the tank.
NOTE: To protect against untimely corrosion of hot and cold
water fittings, it is strongly recommended that di-electric
unions or couplings be installed on this water heater when
connected to copper pipe.
1. Look at the upper pipe nipple on the water heater. The water
outlet is marked hot. Connect the hot water pipe to the hot
water outlet of the water heater.
2. Look at the lower pipe nipple on the water heater. The cold
water inlet is marked cold. Connect the cold water pipe to
the cold water inlet of the water heater.
NOTE: Your water heater is insulated to minimize heat loss
from the tank. Further reduction in heat loss can be
accomplished by insulating the hot water lines from the
water heater.
FIGURE 9.
T & P Valve and Pipe Insulation
Remove insulation for T & P valve and pipe connections from
carton.
Fit pipe insulation over the incoming cold water line and the hot
water line. Make sure that the insulation is against the top
cover of the heater.
Fit T & P valve insulation over valve. Make sure that the insulation
does not interfere with the lever of the T & P valve.
Secure all insulation using tape.
