Instructions

The Viega Mixing Station provides supply water temperature

modulation when connected to a variety of heat sources

such as conventional or condensing boilers, water heaters,

or geothermal heat pumps. Stations are now available

with 3-speed circulator pumps either in high or low head.

Boiler connections can be made with ProPress, PEX Press

Adapters, or Copper (male) for soldering. Red and blue caps

on the ProPress Ball Valves clearly indicate system supply

and return connections. A built in sensor well allows easy

mounting of the supply temperature sensor for the Basic

Heating Control.

Features

• Ready to Hang, Factory Tested

• Ideal for Direct Connect or Remote Locations

• Can be Manually or Electronically Adjusted

• Versatile Boiler Side Connections

• Compatible with Most Heat Sources

Product Instructions Installation 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 predrilled 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.

Product Instructions Manual Air Bleeder Purge Valve (Draw Off) Manual Air Bleeder Isolation Ball Valves Pressurization Kit Purge Valve (Draw Off) Diverting Valve Pressure Testing Before the finish floor is installed and during a concrete pour the radiant system must be pressure tested. Air or water may be used as the medium. The following procedure is recommended by Viega. Check with the local authority having jurisdiction for additional test requirements. 1. 2. 3. 4. 5. 6.

Product Instructions Purging Assuming that the heat source is already filled and purged: Stainless Balancing Manifolds Supply manifold: remove black caps to expose balancing valve. Use a 5mm allen wrench to open and close each circuit. Return manifold: use each blue return cap to open and close each circuit. Stainless Balancing and Flow Meter Manifolds Supply manifold: lift locking cap and turn flow meters to open and close each circuit.

Product Instructions Setting Safety High Limit The Mixing Station is provided with a pre-installed temperature safety high limit feature that allows a maximum fluid temperature to be set. This feature should be used when purging is complete and system is fully operational. To use this feature follow the steps below: If radiant system is being serviced, the safety high limit must be turned off for purging. Reset after purging. Viega...
