Taco 0012 Instruction Sheet

0012 & 0013 Multi-Speed Cartridge Circulator with Integral Flow Check
SUPERSEDES: January 18, 2014
Plant ID# 001-4195
APPLICATION:
• Maximum operating pressure is 125 psi (862 kPa).
• Maximum water temperature not to exceed nameplate rating.
• Cast iron circulators are to be used for closed loop systems only.
• Taco Cartridge circulator pumps are for indoor use only – employer uniquement a l´interieur.
• For use with water or maximum of 50% glycol/water mix systems only.
WArNINg: Do not use in swimming pool or spa areas; pump has not been investigat-
ed for this application.
WArNINg: In the event the electrical box has been pulled off of the housing, DO NOT
attempt to reattach it. Use of any other screw may short out the stator windings, cre-
ating 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, mak-
ing 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 – ATTENTION: Employer des fils d´alimentation
adequats pour 90°C.
WArNINg: To avoid electrical shock, disconnect the power supply to the circulator
and the main electrical unit.
INSTALLATION:
CAUTION: Installations at higher elevations over 5000 feet must have
higher fill pressure of 20 psi minimum to prevent pump cavitation and
flashing. Premature failure may result. Adjust expansion tank pressure
to equal fill pressure. A larger size expansion tank may be required.
1. Location – Install the "00" circulator on the system supply side of the boiler
"pumping away" from the expansion tank as shown in Figures 4, 5, and 6. This
is the best pump location for optimum system performance and maintaining
positive system pressure.
CAUTION: Do not use flat rubber gaskets. Only use o-ring gaskets
provided or leaks may result. Warranty will be void.
2. Mounting position – Mount circulator with the motor in the horizontal posi-
tion. It may be mounted vertically with the motor up, provided that the sys-
tem cold fill pressure is at least 20 psi (138 kPa) to ensure proper air purg-
ing and prevent flashing. Make sure that the junction box is NOT located underneath the circulator. See Figure 3.
3. Rotating body – Body has an arrow on the front that indicates direction of flow. To rotate body, remove the four body bolts, rotate
body and replace bolts.
4. Electrical connections – Observe all applicable codes when connecting to power supply. The motor is thermally protected, and does not
require additional overload protection. Remove smaller conduit box cover. Attach the white wire to the white (common) power supply
wire and the yellow wire to the black (hot) power supply wire. See Figure 2.
5. Fill system with tap water or maximum 50% glycol/water mix – The system must be filled before operating the circulator. The bearings
are water lubricated and should not be allowed to operate dry. Filling the system will result in immediate lubrication of the bearings.
It is always good practice to flush a new system of foreign matter before starting the circulator.
6. Circulator operation – Operate the circulator for 5 minutes at full speed immediately after flushing the system to purge remaining air
from the cartridge. This is especially important when installing the circulator during the off-season.
7. Turn speed dial on circulator to the desired speed and performance range. See Page 3 for performance curves.
