WARNING
When water is at a high temperature and high pressure, excessive splashing of hot water
may occur that could result in injury.
1.4. PLUMBING CONNECTIONS
The plumbing installation should be done by a licensed plumber and must comply with local and national codes.
The instructions for appliances connected to the water mains by detachable hose sets shall state that new hose sets
will be used and that the old hose sets should not be reused (if applicable).
1.4.1. WATER INLET CONNECTIONS
If your appliance is equipped with a faucet or a water fill option connections to a potable water supply will be
required. If a single water connection is required it is recommended that the appliance is connected to hot water
supply. This will greatly decrease the time and energy required for the appliance to reach operating temperature.
Prior to installation, a water treatment specialist should inspect the water supply. Water hardness should contain
no more then 2.0 grains/gallon. The pH level should be between 6.5 and 8.0. These conditions can be obtained
with the use of a properly maintained water softener. The incoming water pressure should be between 20 psi (138
kPa) to 60 psi (414 kPa). For higher water pressures, a high-pressure regulator must be installed to inlet plumbing
to avoid damage caused by water hammer. The maximum allowable incoming water temperature is 180°F
(82°C). Have your water tested and record the measured values below.
1.4.2. DRAIN CONNECTIONS
Each tank has a drain that can be connected to a drainage system. Each tank also has an overflow line. The
overflow connection is after the drain valve to provide an unobstructed overflow path. The tank drain and
overflow line for each tank is connected together to form a common drain line.
When there are more than 2 appliances joined together the common drains can be connected together with a
manifold that has a 1-1/4” NPT outlet connection. The outlet on the can be mounted so it can drain under the left
or right hand unit.
