Installation Guide
Manifolds
Each manifold has a galvanized back plate for easy mounting to any structure.
The cover plate, for labeling purposes, is constructed of 1/4" ABS. All manifolds
are bolted to the back plate, rather than screwed. Each manifold consists of two
inlet ports that supply the dual chambers. Typically one inlet is used for cold
water supply, and the other inlet is used for hot water supply. However, both
inlets may be used for either hot or cold water. The inlets are not temperature
specic. The water inlets connections are 3/4" PEX Barb, The outlets are 1/2"
MPT. 1/2" FPT Swivel x Barb valves are included.
Each manifold is individually boxed, and includes red and blue labels for
indicating the destination xtures. Keep the manifold in it’s carton until ready
for installation. Protect the manifold from dust and debris until plumbing
system is fully installed.
How To Install:
1. Count the number of cold and hot water locations in the house. Be sure to include outside hose bibs and the
refrigerator ice maker.
2. Make sure the manifold has as many ports as the house has hot and cold locations.
3. Find an accessible location near the water heater, but not closer than 18" from the water heater outlet, to place
the manifold.
4. Attach the shut o valves.
5. Position the manifold in the desired location and nail or screw the mounting bracket to the studs. Make sure all valve
handles have room for operation.
6. Attach 1/2" PEX pipe to the inlets and outlets and crimp or clamp securely. Close and cap all unused manifold ports.
7. Label each connection to the water location it supplies. Labels are included with each Apollo manifold.
Manifold Installation Warnings:
• Before and after installation, ensure manifold is kept in a location with limited exposure to chemicals, paint, hazardous
materials, debris, excessive heat, direct flame, or moving objects that could cause damage.
• The manifold should be located in an area that will not be covered permanently with sheetrock, plywood, or paneling.
• Manifolds should not be installed or kept in a location exposed to freezing temperatures.
• Do not allow water to freeze in the manifold.
• Do not use pipe dope or tape to seal any fittings on the manifold.
• Care should be taken not to over or under tighten fittings.
• Distribution lines must connect to the connecting valves in a straight line perpendicular to the manifold as to avoid
bending stress on the valves.
• Manifolds should be installed per all local and national building/plumbing codes. Where a conflict exists between
installation instructions and local requirements, the local codes shall take precedence.
• The installer must also meet all qualifications required by the state and/or local administrative authority administering
the provisions of the code where PEX piping is installed.
• Apollo is not responsible for leaks and property damage caused by failure to follow the installation instructions.
