ONGA
1. Run 50mm PVC pipe line from the spa pool manifold outlet to spa blower position
(maximum operating distance 12 metres), ensuring that the 50mm pipe line has a
minimum fall of 1:10 back to the spa, this will allow the pipe line to have minimum
water lying in the pipe (refer diagram 1).
2. Run your vertical 50mm pvc pipe a minimum of 600mm above
the spa pools maximum water level.
Allow 24 hours for glue vapours to dissipate from the pipe work before
mounting spa blower onto pipe (failure to do so may cause damage to the
spa blower, pipe work and void warranty). Place the blower on the pipe and
tighten the stain-less steel mounting screw located on the check-valve
(refer diagram 1).
DO NOT GLUE THE SPA BLOWER TO THE 50MM PIPE.
SPA BLOWER INSTALLATION AND OPERATION INSTRUCTIONS
3. If the spa blower is to be mounted below water level, extend the
air loop 600mm above the maximum water level and return back to
the spa blower, drill a bleed hole after loop to remove any
condensation (refer diagram 2). DO NOT create a water trap in the
blower supply pipe (refer diagram 3), as the water lying in the pipe
will create additional back pressure on the spa blower. Mount the
spa blower as instructed above (2).
