CAUTION:
To prevent personal injury, ensure all water
pressure is released from the pressure system prior to work
being performed. Ensure pumps are disconnected and / or
electrically isolated.
WARNING:
It is strongly recommended that the system is
protected by a suitable pressure relief valve set at or below
the maximum tank pressure rating. Failure to install a relief
valve may result in tank explosion in the event of a system
malfunction or over pressurization, resulting in property
damage, serious personal injury or death.
WARNING:
If the pressure tank leaks or shows signs of
corrosion or damage do not use it.

PressureWave™, Max™, UltraMax™, M-Inox™, E-Wave™,
All-Weather™, Challenger™, C2-Lite CAD™, and
FlowThru™ Series tanks are designed for use in well water or
potable water booster systems. Refer to Sec. 1 for installation
details.
HeatWave™ and SolarWave™ Series tanks are designed
for use in non-potable closed loop hydronic or solar water
heating systems. Refer to Sec. 2 for installation details.
ThermoWave™ Series tanks are designed for use in open loop
potable water heating applications. PressureWave™, E-Wave™,
Challenger™ and SuperFlow™ Series may also be used in
open loop potable water heating applications. Refer to Sec. 2
for installation details.
See tank data label for maximum working pressure and
maximum temperature.
Be sure to protect tank, piping and all system components
from freezing temperatures.
The manufacturer is not responsible for any water damage in
connection with this diaphragm pressure tank.
Installation
In order to ensure your tank provides its maximum service
life it should always be installed in a covered, dry position. The
tank should not be allowed to rub against any surrounding hard
surfaces, such as walls etc.
Install the tank at a suitable location to prevent water damage
due to leaks. The tank should always be located downstream
from the pump. If the tank is located at a lower elevation than
the demand then a check valve should be installed. If the tank is
installed remotely from the pump then install the pressure switch
near the tank. The tank should be installed as close as possible to
adverse effects of added friction loss and differences in elevation
between the tank and / or the water mains’ and the pressure
switch, transducer or sensor.
1.2 System Connection
1.
2. Level as necessary. All vertical and horizontal model tanks
in the vicinity the tank should be mounted on a resilient
mounting. Tanks with steel bases should be mounted using
supplied “L” brackets, while tanks with plastic bases should be
mounted through the holes in the base. For bases without
holes, holes should be drilled at four points equally distant
along the rim of the base and then mounted accordingly. Inline
tanks should be connected directly to the pump or to the
supply line using a “T” connection.
3. Connect the tank to the pump supply line with a short pipe to
eliminate unnecessary friction loss.
4. All piping should be in accordance with prevailing local codes
and standards.

connections.
6. Tanks mounted on booster sets should be strapped down for
shipment.
1.3 Adjusting Precharge Pressure
Correct precharge is required for proper tank performance.
1. For tanks installed with a pressure switch controlled pump
with a differential pressure set up to 2 bar (30 psi), the
precharge should be set to 0.2 bar (2 psi) below the cut-in
pressure.
2. For tanks installed with a pump controlled by a pressure
switch with a pressure differential greater than 2 bar (30 psi),
electronic controls or variable speed controls, the precharge
should be set to 65% of the cut-out or maximum system
pressure.
3. For tanks installed on mains’ pressure, the tank precharge
should be set equal to the mains’ pressure. For mains’ pressure
