Instructions

PI-PR-561051 0312 (Enhanced Mixing Station)

Mounting the Mixing Station

The Mixing Station comes factory tested and mounted on brackets making it ready to hang. Simply install

four pan head screws, or wood screws with washers, into the pre drilled holes in the mounting brackets. See

Dimensions on page 2 for mounting holes and spacing. The station brackets have the same offset as the

Manifolds, making direct connecting simple. The station can also be used as a centrally located control center for

remote manifolds instead of direct connecting to manifolds. Use the 1” M NPT adapters at the end of the station

to connect to Viega PEX Press ttings and ViegaPEX Barrier or FostaPEX tubing to remote manifolds in different

areas of the job.

Connecting The Enhanced Mixing Station to a primary loop ( boiler loop)

The Enhanced mixing station is available in three boiler side connections:

1. Copper (male) stock code number 12151 -- Copper (male) when soldering stations to boiler loop

(primary loop).

2. ProPress stock code number 12152 -- ProPress connections when connecting station to boiler loop

(primary loop).

3. PEX Press stock code number 12153 -- ViegaPEX Barrier or FostaPEX when connecting the station to boiler

loop (primary loop).

Note: When using Copper (male) stations be aware that the isolation ball valve is a ProPress connection and

needs to be protected when soldering. The Copper (male) length is in accordance with ProPress distance

requirements for soldering, but take additional steps to be sure press connection is protected to prevent the

sealing element from being damaged. A damp rag wrapped around the ProPress Ball Valve will protect the

sealing element from overheating.

Connecting The Enhanced Mixing Station to Stainless Manifolds

Connecting the The Enhanced Mixing Station to Stainless Manifolds

Use Teon tape to wrap the 1” M NPT mixing station adapter. Wrap tape in the same direction as tightening the

adapter. Once taped, apply a small amount of pipe dope on top of the tape for rst few threads. Connect the

supplied 1-1/4” x 1” Brass Bushing to the 1” M NPT adapter. Use the 1-1/4” threads to connect the 1-1/4” union

connection to the Enhanced Mixing Station. Do this for both supply and return manifolds. Supply and return

manifolds are identied by the red (supply) and blue (return) caps. The Mixing Station is identied by the red cap

ProPress Ball Valve (supply) and blue cap ProPress Ball Valve (return) caps.

Sensor Well

The sensor well is designed to house the supply temperature sensor for the Basic Heating Control. Align the

at side of the sensor perpendicular with the set screw. Tighten screw with athead screwdriver (thermostat

screwdriver) to secure the sensor in the well.
