The
B

TREAM

assembly package contains
all necessary parts for the installation of the unit
into concrete, gunite, liner or fiberglass pools.
: All necessary screws and bolts included
with the
B
ADU

TREAM

are stainless steel or
plastic.
ALL
screw threads and threaded inserts are
METRIC! ONLY METRIC
bolts and nuts may be used!
The two exceptions are the connecting thread for
the intake and delivery connections on the
B
ADU
S
TREAM

and pump housing and the hardware
for the air regulator assembly. The intake and delivery
connections on the pump model 21-80 are 3" NPT
threads and 4" slip (3" on pump model 98). The air
regulator assembly hardware is US standard thread.
: The center of the housing (the nozzle)
should be 10"
BELOW water level for maximum
efficiency.
The air regulator should be approximately
4"
ABOVE
the water level. (See fig. 3.)
: When connecting the pressure line to the
pressure connection on top of the 4 HP Pump Model
21-80, first install a 15 cm (6") riser (fig. 1) before
installing an elbow and leading the pressure line
downward to the pressure connection at the jet housing.
This will guarantee trouble-free priming of the pump.
(Not required for the 3.5 HP Model.)
: The suction line should run below water
level right up to the pump location.
: In areas with soft soil conditions or with
frequent earth movement, a flexible section of hose
should be attached to the back of the jet housing to
prevent housing breakage.
: Throughout the entire installation, make
sure plumbing connected to the
B

housing is well supported. Unsupported plumbing
will crack the
