PLEASE READ THE FOLLOWING INSTRUCTIONS CAREFULLY FOR IMPORTANT
GENERAL SAFETY INFORMATION AND ADDITIONAL SPECIFIC SAFETY ALERTS.
UNIT MUST BE INSTALLED BY A LICENSED PROFESSIONAL.
Pre-Installation
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
a reduction in pump cycle time can result from loss of
tank air pressure which can mean there may be internal
corrosion. Any re-pressurization or additional pressure
could result in rupture or explosion.
• Do not use with components or materials that are
incompatible with the Guardian CP.
Plumbing Connection
1. The Guardian CP should be mounted as close as
possible to the pressure tank.
CODES. DO NOT LOCATE THE UNIT WHERE IT CAN
BE AFFECTED BY FLOODING.
2. You may assemble the Guardian CP to a "Tank Tee" or
"Tank Cross" (Figure 1) or adapt the unit to an in-line
pipe fitting (Figure 2). Use pipe sealing tape or pipe
sealant. Tighten the Guardian CP using the wrench
flats provided on the bottom connection. DO NOT
EXCEED 15 LB./FT. of torque.
NOTE: Do not allow pipe sealant or other contaminants to
enter the small port in the Guardian CP connection.
NOTE: A mechanical pressure gauge is not required.
Use the appropriate plug to block any unused ports.

ELECTRICALLY GROUNDED.
NOTE: The Guardian CP will operate on 115 VAC & 230 VAC
systems. Its ambient air temperature rating is 122°F / 50°C.
NOTE: The Guardian CP has openings to accept standard
conduit terminations. Outdoor installations must use
watertight connections.
1. Disconnect power and verify with a volt meter.
2. Determine the pump electrical requirements. If
unknown, contact the pump manufacturer.
3. Select the appropriate wire gauge per local codes and
the pump manufacturer's recommendation.
4. Loosen the screw on the cover of the controller and
remove the plastic cover, exposing the wiring leads.
(When reassembling cover, do not over-tighten screw.)
5. The wire conduit hub is to be connected to the conduit
before the hub is connected to the enclosure. The
maximum hub diameter cannot exceed 1.15" (1 3 /20").
Larger hub will interfere with cover closure.
6. The opening of the enclosure shall be closed with hubs
rated 3, 3S, 3SX, 3X, 4, 4X, 6 or 6P.
NOTE: Steps 5 and 6 are required for outdoor installations only.

7. Following all electrical codes, wire the Guardian CP
using the appropriate wiring diagram (Figure 3).
