Operation

This pressure tank has been designed to store and deliver potable water under pressure in a domestic water system. It features a diaphragm or membrane design that keeps the system water in a safe and contaminant-free chamber for pressurized water supply between pump cycles. Without a pressurized storage tank, a domestic water system’s pump would turn on every time there is a demand for water, even if the demand is small. This frequent on/off cycling shortens the useful life of the pump. Pressure tanks are designed to store water when the pump is running and then deliver pressurized water to the system when the pump is shut off (See Fig. 1). A properly sized tank will store at least one gallon of water for every gallon per minute (GPM) of pump capacity. This allows for fewer pump starts and longer run times which maximizes the life and efficiency of the pump system.

WARNING: COMPLIANCE TO CODES This pressure tank must be installed by a qualified professional following all local and national plumbing and electrical codes. The tank must be annually inspected for visible signs of damage, corrosion, or leakage and replaced immediately if these signs are present. Failure to follow these instructions and codes may result in serious injury, death and/or property damage and will void the product warranty.
WARNING: EXPLOSION HAZARDThis pressure tank is designed for water storage at a maximum pressure of 150 psi and a maximum temperature of 194° F. The system must be protected by a suitable pressure relief valve set at a maximum of 125 psi. This pressure tank is shipped with a pre-charge of 38 psi and any adjustment to the pre-charge must be done prior to installation and at ambient temperature. Do not adjust the pre-charge of this tank if the product is corroded or damaged or shows any signs of diminished integrity. The maximum allowable pre-charge in this pressure tank is 80 psi. Failure to follow these instructions may result in serious injury, death and/or property damage.
WARNING: PROPER PLACEMENT OF TANK This pressure tank should be installed in a covered, dry area. This tank must not be installed in a location that is subject to freezing or where it can rub or vibrate against a hard surface. The tank must be installed in a suitable location to prevent water damage due to leaks and have means for adequate drainage. The manufacturer of this product is not liable or responsible for any water damage associated with the installation and/or failure of this product. Failure to follow these instructions may result in serious injury, death and/or property damage.
WARNING: FOR POTABLE WATER USE ONLY This pressure tank is intended for use with potable water systems only. Use with non-potable water or any other fluid may be dangerous and will void the warranty. This product’s performance and lifespan can significantly be impacted by aggressive water conditions. A water test should be conducted specifically looking for corrosive water, acids and other relevant water contaminants which, if present, must be treated appropriately. The system piping must be properly grounded to earth. A dielectric union may be required in the system. Failure to follow these instructions may result in serious injury, death and/or property damage.

ADJUSTING TANK PRE-CHARGE

Correct pre-charge is required for proper tank performance. Any adjustments to the factory pre-charge must be done prior to initial tank installation and with zero pressure on the system.

WARNING: Do not adjust the tank air pressure if there are any visible signs of corrosion on the tank. If this pressure tank shows any visible signs of corrosion or rusting, the tank must be replaced immediately. Failure to follow these instructions may result in serious injury, death and/or property damage.
DO NOT ADJUST THE PRE-CHARGE OF THE PRESSURE TANK WITH THE SYSTEM UNDER PRESSURE.

This pressure tank is shipped from the factory with a pre-charge of 38 psi.

For tanks installed with a fixed speed pumping system with a differential pressure set up to 30 psi, the pre-charge should be set to 2 psi below the cut-in pressure. (Example: In a 20/40 pressure switch, the tank is set to 18 psi; a 30/50 pressure switch, tank is set to 28 psi; and a 40/60 pressure switch, tank is set to 38 psi.)
For tanks installed with a pump controlled by a pressure switch with a pressure differential greater than 30 psi, electronic controls or variable speed controls, the pre-charge should be set to 65% of the maximum system pressure.
For tanks installed on mains pressure, the tank pre-charge should be set equal to the system pressure. If the system pressure exceeds 88 psi then a suitable pressure reducing valve should be installed.

WARNING: In no event should the tank pre-charge exceed 80 psi.

TO ADJUST TANK PRE-CHARGE PRIOR TO INSTALLATION

Remove the protective cap from the air valve.
Check the tank pre-charge pressure using a suitable pressure gauge.
If required, add air at ambient temperature to the tank using a manual pump or air compressor until the proper pre-charge pressure is reached.
Replace the protective cap on the air valve.

TO ADJUST TANK PRE-CHARGE AFTER INSTALLATION (IF REQUIRED)

Disconnect all power to the system pump.
Drain the tank of water by opening a faucet or drain valve.
Add or release air at ambient temperature, if required, using a manual pump or air compressor until the proper pre-charge pressure is reached.

Installation location

WARNING: The tank must be installed in a suitable location to prevent water damage due to leaks and have adequate drainage. The manufacturer is not liable for any water damage that occurs in association with tank installation or failure.
In order to ensure your tank provides its maximum service life, it should be installed in a covered, dry area that is not subject to freezing. This tank must not be installed in a location where it can rub against a hard surface such as a wall.
The tank should always be located downstream from the pump. If the tank is located at a lower elevation than the demand, a check valve must be installed.
The tank should be located as close as possible to the system pressure switch, transducer or flow sensor to reduce the negative effects of added friction loss and/or differences in elevation between the tank and these components.
This tank has been designed to be mounted on a level surface and must be adequately supported around the entire base using the mounting holes or brackets provided. Inline tanks should be connected directly to the pump or the supply line using a 3- or 5- way fitting.

If replacing a 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.

Connecting tank to system
WARNING: 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.
WARNING: 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) 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)

EASY AS 1-2-3 INSTALLATION

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.

WARNING: All piping and electrical components should be in accordance with prevailing local codes and standards.

STARTING 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.
WARNING: Inspect the installation for water leaks paying close attention to the connection between the pressure tank and the system piping.

MULTIPLE TANK INSTALLATION

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 precharge 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. $globalwater-PWN-US-160LV-PressureWave-42 $9$$ $globalwater-PWN-US-160LV-PressureWave-42 $10$$

MAINTENANCE

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.
