Location and
Installation of
Pump
The plrmp should be in a readily
accessible
location
to allow easy service or repair if required.
The Model
Series
200 Pump
has excellent
priming
characteristics.
It
can be located above, even with
or
below the water
tank level. Secure the pump with
screws
through the rubber feet in the mounting plate. Take
care
not to
tighten the screws so tight that they depress the
rubber feet
as
this prevents
the shock absorber effect and
increases
pump
noise.
The water tank must be vented to the outside of the
coach.
It
is
essential
that a filter be
used
in
the pump
input
line
to
prevent particles from entering rhe pump head. A
tank filter or an
in-line
filter
is ideal.
Filter screen should
be
50
mesh
or
smaller.
Electrical
The pump should be on a circuit of its own. Use
14
gauge
wire up
to
20 feet and 12
gauge rvire
from
20
feetto
50 feet. Run the
same
gauge
ground wire
back

when traveling.
Plumbing
Use
only high
pressure
potable u'ater hose (Shurflo Part
#007-003) or equal. Any length
hose
may be used on the
input
(non-pressure)
side. The output hose should not
exceed
24
inches
to
comply
r,vith
most codes.
Care
should be taken to avoid any kinks in the line. Use
hose
clamps at both ends
of
each hose. Clamps prevent air
leaks
which can prevent proper
priming.
Check valves used in
the system must be
a
free
flow
design.
If you
can
blow through it in the direction of the
flow the valve
is
suitable.
If you cannot, it may
cause ex-
cessive
restriction.
CAUTION: Do not
use
pipe dope on the input
side
of the
pump.
Pipe
dope can get into the pump head and
may
cause
failure.
Water purifiers must be
on a
separate
line

Requirements
The inside diameter of the
plumbing line
is
of utmost
importance.
If too
small,
it
increases
back pressure and
reduces
the flow causing excessive pump cycling. Main
lines should be at least
l/2
inch in diameter and shorter
"feeder" lines
to
the
faucets should
be
3/8
inch
in
diameter.
Allfittings
used
to
join
sections
of the
plumbing
should have the same
flow
diameter as the lines. Filter
screens
should
be
removed
from
faucets
as
they may lime
up or clog, thus causing
a
problem.
The output hose on the pump may be exposed
to
pressure
when the RV is connected to city
water.
