Spray

FAQs
—
--Why
does the
pump not
run all the
time?
This is
a demand pump
and only
runs with
ow;
spray wand,
by-pass,
spray
tips or leak
in system
--Why
does the
pump surge
while
using the
spray
wand?
Low flow
may cause
the pump
to surge
(or cycle).
This could
happen
when
the spray
wand
is adjusted
for
a small
or
ne
spray
pattern.
To overcome,
slightly
open the
by-pass
valve.
--How
do I adjust the
pressure?
Pressure should
be adjusted
by regulating
the
by-pass
valve
(slightly
opening
or closing).
What is the
optimal
operating
pressure?
40 PSI
- This can
be accomplished
by turning
on
the pump
and adjusting
the bypass
valve
until
the gauge
reads
40
PSI (or
slightly
higher). The
pump will
run continuously.
Ensure
that
the boom
and/or
handgun
is not
spraying
while
you set
the
pressure.
The
pressure
will drop
slightly when
the boom and/or
handgun
is
operated.
--What
pressure
should the
pressure
gauge
read?
Please
refer to the
operation instructions
for boom
operating
pressures,
varying
boom
pressures
can be
achieved
by regulating
or
adjusting
the by-pass
valve.
Typically
the spray
wand
will be
operated
between
20 and
40 PSI.
--My
pump quit
and will not
restart
- what
should
I check?
Check all electrical
connections.
Ensure switch
is in
the on
position.
Check
in-line fuse
and/or
fuse
in car
adapter
end.
Ensure
correct
voltage
+/-
10%.
12-13
volt
--Low flow
or no ow
at all
- what should
I check?
Check
for a clogged
suction hose
and/or
suction
strainer.
Often
you will need
to
clean the
suction
strainer.
Check
for
proper
voltage
--Is there
a fuse
for the sprayer?
‘
Yes, either
an in-line
fuse, a fuse
located in
the car
adapter
housing
or both.
--What
size fuse
should
I use as
a replacement?
7.5 amp
--What is the
range
of the spray
wand?
35
feet
max
--How
should
I clean the
tank after
use?
1)
Rinse tank thoroughly
with
water
only, empty,
rell with
water.
2)
Open shut-off
and allow
water
to run through
discharge
assembly.
Empty
sprayer.
3) Store sprayer
tank
upside down,
in a warm
dry location.
--Is
there an
adjustment
screw
on the pump
to adjust
pressure?
Yes, please
refer to
the operation
instructions,
"Adjusting
the Pressure
Switch“.
--How
do I remove
/ replace
fuse?
Unscrew
in-line
fuse connector,
or
unscrew
the car adapter
housing.
--Can
the spray
tip on
the wand
be replaced
with a
different
type
of tip?
Yes, however
your
wand comes
with
a #18
tip which
is standard.
Brass
tips generally
produce
better
spray patterns
than plastic.
--Each
time I turn
on the
pump my
fuse
blows.
1) Excessive
voltage
2) Improper
adjustment
of the pressure
switch
3)
Damaged
wiring
harness.
--What
is the
warranty
(time duration)
on pump,
tank,
and accessories?
1 years as stated
in operation
instructions.
--Pressure
gauge reads
85 -90
psi before
shutting
off - should
pump
shut
off at
60 psi?
Pump
7802 2.2
GPM comes
preset
from the
factory
to shut
off at 60
PSI.
Should
this vary
please
see,
"Adjusting
the
Pressure
Switch"
in the operation
manual.
Turn
on pump
and hold
spray
wand open,
slowing
adjust
until
the
pump
shuts
off at
60 PSI.
--Pump continues
to
run and
surge when
not
spraying.
Ensure
the by—pass
is completely
closed
and
your system
has
no leaks.
Check
by-pass
hose
to ensure
no
uid
is passing
through
the
valve
while in the
closed position.
If
so replace
valve.
WARNING
- Ensure
the wiring
harness does
not become
pinched
or damaged
in any
way.
This may
damage
the pump
or cause
the wiring
harness
to overheat,
resulting
in
a melt down
or re.
