Application:
The Taco Plumb n’ Plug (PNP) “00” Series circulators are
designed to increase comfort and conserve water and
energy by decreasing the delivery time of hot water to out-
let fixtures. An average residence can save up to 25 gallons
of water per day, 9,000 gallons a year. A 6 foot line cord is
pre-wired on all PNP models providing an easy installation.
Simply plumb-it-in then plug-it-in.
Pump Control Options:
1. The basic PNP with line cord is designed for constant
circulation where the pump runs 24 hours a day.
2. An optional aquastat kit (#563-2) can be added to con-
trol pump operation to maintain water temperature
between 95˚F – 115˚F.
Two automatic timer options are available to control
pump operation and increase total energy savings.
3. A 24 hour/15 minute interval analog timer controls
pump operation for the same time settings every day,
usually early morning and early evening.
4. The digital 7 day programmable timer can be set for up
to 8 different on/off and day/time settings to match
homeowners’ weekly schedules and maximize energy
savings.
Benefits:
•
Water Conservation:
The average residence can save
up to 25 gallons of water per day, 9000 gallons per year.
•
Comfort and Convenience:
Hot water is always avail-
able in seconds.
•
Efficiency:
24 hour analog timer can be set to control
daily pump operation and increase energy savings. 7
day digital timer allows for different settings each day to
match homeowner’s weekly schedule, for even greater
convenience and savings.
•
Reliability:
Unique cartridge design runs quietly and is
easy to replace.
Sizing:
• 003-PNP should be used when the total run of pipe
(supply and return) is under 200 feet of
3
⁄
4
" pipe.
• 006-PNP should be used when the total run of pipe
(supply and return) is from 200 to 400 feet of
3
⁄
4
" pipe.

WARNING: Do not use in swimming pool or spa areas;
pump has not been investigated for this appli-
cation.
WARNING: In the event the retaining screws have been
pulled out of the housing, DO NOT replace them.
Use of any other screw may short out the stator
windings, creating a risk of electrical shock.
CAUTION: When installing electrical connections, do not
apply mechanical loads to the capacitor box;
otherwise, retaining screws may be pulled out
of the housing, making circulator unusable.
CAUTION: 1. The addition of petroleum based fluids or
certain chemical additives to systems utilizing
TACO equipment voids the warranty.
2. Use supply wires suitable for 90°C – ATTEN-
TION: Employer des fils d alimentation ade-
quats pour 90°C.
