Instructions / Assembly

All tanks must have the same pre-charge for the system to function properly. Tanks should be installed on a header to ensure all
tanks receive equal and balanced pressure. Adjust each tank pre-charge as detailed in the adjusting tank pre-charge section.
The system pressure switch or control should be centrally located (see Figure 2.1 & 2.2) in order for the tanks to function
properly.
CONNECTING TANK TO SYSTEM
IF REPLACING A TANK
Remove and discard the protective cap from the pressure
tank’s stainless steel water connection. Connect the
tank cross / tee fitting (3- or 5- way connector for inline
or horizontal pressure tanks) into the pressure tank with
adequate pipe sealant (Teflon™ Tape or pipe dope) on the
male threads. Be cautious to not over-tighten, cross, or
strip threads when connecting fittings.
Once the fitting is securely tightened, be sure that the
threaded holes for your pressure switch and pressure
gauge on the tank connection fitting are in the upward
position. (See vertical tank examples Figures 1.1, 1.2, and
1.3, horizontal tank example Figure 1.4 and inline tank
example Figure 1.5).
With adequate pipe sealant, connect all of the fittings,
valves, pressure switch, pressure gauge and water system
pipe / connection unions to the connection fitting.

PRESSURE TANK INSTALLATION MULTIPLE TANK INSTALLATION
It is recommended that the system is checked annually by a qualified professional. The pressure tank and its connections
to the system should be visually inspected regularly for any signs of water leakage or corrosion on the exterior of the tank or
connection. If any is seen, replace tank immediately. Although our PressureWave™ diaphragm tank design is maintenance-
free, damaged and/or poorly working accessories and tank fittings can adversely affect the tank's performance, as can extreme
temperature variations and age. Therefore, the tank pre-charge should also be checked periodically.
MAINTENANCE
Disconnect or shut off all electric
power to the water supply/pump
system. Shut off the water supply
to the system and remove all water pressure from the
system. Failure to follow these instructions may result
in serious injury, death and/or property damage and will
void product warranty.
A suitable pressure relief valve,
set at a maximum of 125 psi, must
be installed in the system near the
pressure tank (see Fig.1.1)
All piping and electrical components should
be in accordance with prevailing local codes
and standards.
Inspect the installation for water leaks
paying close attention to the connection
between the pressure tank and the system piping.
The pressure tank should be installed in the incoming
water supply line from the pump system and before any
point of user (POU) fixtures. (see Fig. 1.1)
STARTING THE SYSTEM
Before turning on the water supply to the system, open a
water faucet to allow air from the system piping to be purged.
Turn on the power to the water supply and the pump should
turn on, filling the system piping. When the water is flowing
freely from the faucet without air, close the faucet. The pump
will continue to run filling the pressure tank.
With all power turned off to the pump system, drain the old
tank, close all water flow to the tank and disconnect it from
the system. Check all fittings, valves, switches and gauges for
proper working condition and replace as appropriate.
