DANGER! EXPLOSION HAZARD. When the well tank has been in
service and a change to a higher pre-charge pressure is necessary
due to a required change in the pressure switch setting, failure to follow instructions below
can cause a rupture or explosion, possibly causing serious or fatal personal injury and/or
property damage.
• Do not adjust or add pressure if there has been a loss of air.
• Do not adjust the pre-charge pressure if there is visible exterior corrosion.
• Do not adjust the pre-charge pressure if there has been a reduction of the pump
cycle time or the pre-charge pressure compared to its initial setting. This is because
reduction in pump cycle time can result from loss of tank air pressure which in turn
can mean there may be internal corrosion and any re-pressurization or additional
pressure could result in rupture or explosion.
• Do not install with components that are incompatible with the DC2.
NOTE: Inspect for shipping damage and notify freight carrier or store where purchased
immediately if damage is present. To avoid risk of personal injury and property damage,
if the product appears to be malfunctioning or shows signs of corrosion, call a qualified
