If the installation of the ELITE requires domestic hot water for a commercial dish- washer, the installer may insert a tee con- nection between the unit and the mixing valve to provide 140ºF domestic hot water. The installer must reference local plumbing codes to ensure if this type of application is permissible.
DANGER
The thermostatic mixing valve MUST be installed and utilized on the ELITE. Removal of the thermostatic mixing valve will result in severe personal injury or death.
CAUTION
The installer should remove the thermostatic mixing valve from the units and install a single thermostatic mixing valve at the outlet of the hot water manifold. The thermostatic mixing valve should be sized according to the required flow rate and pressure drop. Refer to the ther- mostat mixing valve manufacturer specifica- tion and installation instructions for more details.
Reference Fig. 4, page 15 for piping diagram.
Storage Tank Application
For applications requiring large volumes of domestic hot water in a relative short period, the installer may include a storage type tank (see Fig. 5 page 16) in the domestic piping. The installer must:
1.Relocate the thermostatic mixing valve from the ELITE to the outlet of the stor- age tank.
2.Provide recirculation from the storage tank back to the ELITE using a bronze type circulator. Maximum recommend- ed flow rate is 5 to 10 gpm.
The manual valve on the
Domestic Drain Valve
-The installer must install a drain valve and drain leg as shown in Fig. 2 page 14 or Fig. 3 page 15.
-The drain valve should be positioned close to the floor to aid in the siphon action required to drain the inner tank.
Multiple Units Installation
For applications using multiple units the domestic piping should be piped using a bal- anced manifold arrangement.
