Installation
For example, model FP7110T precharged tank
has a drawdown of 5.8 gallons (22L) and is
equivalent to a 42 gallon standard tank that has
a drawdown of 4.3 gallons (16.3L).
Risk of electric shock and
explosion. Disconnect all power to pump and
bleed all pressure from system before working
on pump, tank, or piping.
For jet pump installation, remove AVC tube
from port in pump body or jet body and plug
port (see Figure 3). New pumps come with
plug installed.
Figure 3 - Plug AVC Port when installing pre-
charged tank on existing pumps. New pumps
come with plug Installed.
When working on submersible pumps in wells
be sure safety rope is solidly connected to pump
and to secure anchor at the well head at all
times. Do not drop the pump down the well!
Bleeder Orifices
NOTICE For submersible pump installations,
there may be bleeder orifices in the vertical
discharge pipe. They must be removed and
the tees plugged when a pre-charged tank is
installed in the system. To do this, raise the
pump and discharge piping enough to bring the
bleeder orifices clear of the well. Remove the
bleeder orifices from tees and replace with plugs
(see Figure 4). Bleeder orifices may be any of
several sizes. Have a pair each of 1/2
1
plugs available. Replace pump and reconnect
"
the discharge pipe.
Adjusting Tank Pre-charge
In areas where temperature is high for long
periods of time, tank pre-charge pressure may
increase. This may reduce tank drawdown
(amount of water available per cycle). If this
occurs, adjust pre-charge pressure according to
Chart 1.
Flush all air out of piping system and water
reservoir portion of pre-charged tank. Required
on: new installations, pumps requiring
repriming, and pumps disassembled for service.
