Domestic Piping

3. Solder the U-Tube Assembly onto the

adapter. (See Fig. 5)

4. Once the adapter has suff i c i e n t l y

cooled, re-insert the check valve assem-

bly making sure of orientation and

reconnect onto the mixing valve.

If the installation of the PERFORMANCE

PLUS requires domestic hot water for a

commercial dishwasher, the installer may

insert a tee connection between the unit and

the mixing valve to provide 140ºF domes-

tic 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 PERFOR-

MANCE PLUS. Removal of the thermo-

static 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. 6 page

17 or Fig. 7 page 18.

- 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. 8, page 18 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. 9 page 19) in the domestic piping. The

installer must:

1. Relocate the thermostatic mixing valve

from the PERFORMANCE PLUS to

the outlet of the storage tank.

2. Provide recirculation from the storage

tank back to the PERFORMANCE

PLUS using a bronze type circulator.

Maximum recommended flow rate is 5

to 10 gpm.
