Step IV: Install the new tank.

Install the new tank. Place it where the old tank was or stand
it  in  a  position  so  that  you  can  make  the  pipes  meet  the
tank  cross.  If  necessary,  place  the  tank  on  garden  bricks  or
cinder blocks to make sure that it stands at the right height.
Connect  the  tank  to  the  pump
supply  lines  using  piping  to  fit.
Follow  all  applicable  local  and
state codes and ordinances.

Note:

Do not place the tank where it or
the controls on it will freeze. This
can damage the system.

Screw the pipe unions hand tight
first, then tighten wrench tight
using the pipe wrench.

Re-install the wires in the pressure
switch. Attach the leads to the
connections as you marked them.

(Fig. 16)

4. Replace the cover to the pressure

switch. Check to make sure that
the standard drain/boiler drain
valve is closed.

(Fig. 17)

Remove the plastic cap on the air
valve on top of the tank. Check
the air charge in the tank using the
tire pressure gauge.

Adjust  the  precharge  pressure  in
the  tank  to  be  1  to  2  psi  below
the  pressure  switch  pump  cut-in
setting. First, look inside the cap to
the  pressure  switch  to  determine
the pump cut-in setting. It should
say “20/40” or “30/50” or the like.
The  pressure  in  the  tank  should
be adjusted to be 2 psi below the
lower of these two numbers. That
is, the tank pressure should be set
at about 18 psi if the cap indicates
a  cut-in  setting  of  20/40,  or  set
at about 28 if the cap indicates a
setting of 30/50.

The  table,  "Exhibit  A",  indicates
the air charge in the tank when the
tank  is  shipped  from  the  factory.
Release  or  add  air  to  adjust  the
pressure  properly.  If  the  charge
is  too  high,  release  some  air  by
pressing  down  on  the  pin  inside
the  air  valve.  If  the  charge  is  too
low, pump it up using a bicycle tire
pump or air compressor.

Alternatively, you can adjust the
pressure switch to match the pressure
in the tank. See instructions on the
inside of the cap to the pressure switch
for how to do this.

Step V: Turn the power back on. The pump

will fill the tank. The system is now ready

to use

Open  the  gate  valve  to  let  water
flow back into the tank. This is the
valve  that  you  closed  in  Step  I.3
{See  Step  I.3  for  a  photo  of  the
gate valve}

(Fig. 18)

Turn on the faucet that is the
highest in the house and farthest
from the tank. This will allow air to
exit the system as water enters.

Turn the power back on. The pump
will  start  and  fill  the  tank.  Watch
for any leaks in the system. If you
do  see  a  leak,  turn  the  power  off
immediately and repair the leak at
the joint. It should take 30 seconds
to a minute for the pump to prime
if it is a jet pump. If the pump does
not fill the tank and shut off in one
minute  or  so,  check  the  pressure
gauge.  If  the  gauge  is  moving,
let  the  pump  continue  to  run.  If
the gauge is not moving, turn the
power  off.  This  means  that  the
pressure  switch  is  either  installed
improperly  or  is  defective.  Check
the  manufacturer’s  instructions.
Replace  it  if  necessary  and  test
the  system  again  to  see  that  it  is
installed properly.
