OWNERS MANUAL
Remote Manifold Installation
Robust-Aire systems that were ordered with the optional remote manifold were pre-built with a single air-line
exiting each compressor. Follow the instructions below to assemble and install the remote manifolds.
Installation Tools & Materials:
¾” Sch. 40 PVC Pipe (amount to be determined by user)
¾” Sch. 40 PVC Pipe Couplings (as needed)
PVC Primer and Glue
PVC Pipe Cutter
Shovel or other trenching tools
Pliers (hose clamp installation)
Thread sealant
A trench will need to be excavated to bury the PVC air-line. Start by determining the path of the trench from the
Robust-Aire system to an area by shore. The path should be as straight as possible with a gentle downward
slope from the Robust-Aire system towards the shore. Dig the trench 6” to 8” deep.
For two or three station valve manifolds, excavate an area large
enough to bury the included valve box. An area at least 18” wide by
25” long x 13” deep will be needed. Dig the area deeper and add
crushed rock to allow for needed drainage.
CAUTION
: In northern climates where the ground freezes during the
winter, be sure there are no high or low spots in the PVC air-line.
Condensation in the air line may pool, freeze, and block the flow of air
to your diffuser. This can also damage your compressor.
For RA1 – RA3 systems, a single trench is required.
For RA4 – RA6 systems, either a single trench or two separate trenches
may be required depending on pond size and diffuser placement
locations.
Connect brass barb fitting to PVC adapter, applying thread sealant to
male threads on PVC adapter. Connect barb fitting to rubber compressor
hose lead and secure with clamp.
Connect PVC adapter and PVC pipe with primer and glue. Add pipe
sections as needed to reach the remote manifold.
