Domestic Piping
3. Solder the U-Tube Assembly onto the
adapter. (See Fig. 1)
4. Once the adapter has sufficiently
cooled, re-insert the check valve assem-
bly making sure of orientation and
reconnect onto the mixing valve.
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.
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.
The manual valve on the U-Tube assem-
bly must remain in the full open position
for proper operation of the thermostatic
mixing valve.
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.
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.
