RULES FOR SAFE INSTALLATION AND OPERATION
Risk of explosion. Installation must comply with
all applicable state, provincial, and local statutes, codes and
ordinances. Non-compliant installation may result in product
failure, property damage, and/or personal injury.
1. Read the owner's manual and Rules for Safe Installation and
Operation and Installation instructions carefully. Failure
to follow these rules and instructions could cause serious
bodily injury and/or property damage.
2. Always test water from well for purity before using. Check
your local health department for testing procedure.
3. Before installing or servicing your tank, BE SURE pump
electric power source is disconnected.
4. Release all pressure before working on tank or system. Make
sure all air pressure has been released before removing
tank supply connection fittings.
CH21086 (08/01/21)
5. BE SURE your pump electrical circuit is properly grounded.
6. Remove bleeder orifices, air volume controls or other air
charging devices in existing system.
Risk of explosion. To prevent possible serious or
fatal in jury and/or damage to equipment, system pressure must
be less than 125 pounds per square inch gauge (psig) under any
circumstances. Failure to follow this instruction can result
in tank explosion. If system discharge pressure can exceed
125 psig, install a relief valve capable of passing the full pump
volume at 125 psig. Install relief valve in pump supply line to tank,
as close to tank as possible.
Risk of freezing. To avoid possible equipment
failure, severe injury, and property damage, do not allow pump,
tank, or piping system to freeze.
GENERAL SAFETY
All tanks are factory pre-charged with air. When installing tank,
adjust pre-charge to 4 psig below pump cut-in pressure setting.
To do this, bleed air from or add air to the valve on top of the tank.
For applications with high flow rates, high system pressures
or elevated water and/or air temperatures, it is recommended
to adjust the pre-charge pressure differential to 10 psig below
pump cut-in pressure setting.
NOTICE Always set pre-charge with NO WATER in tank.
Check pressure frequently with an accurate tire pressure gauge
until correct pressure has been reached. For correct pre-charge
pressure settings, see Table 1.
