1. Maximum operating pressure is 125 psi (862 kPa).
2. Maximum water temperature not to exceed nameplate rating.
3. Cast iron circulators are to be used for closed loop systems. Bronze or stainless steel circulators are to be used for
open loop, fresh water, or potable water systems.
4. Taco Cartridge circulator pumps are for indoor use only – employer uniquement a l´interieur.
1. Mounting position – Circulator must be mounted with the motor in a horizontal position. It may be mounted
vertically with the motor up, provided that the system pressure is at least 20 psi (138 kPa).
2. 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. Make sure that the junction box is NOT located underneath the circulator. (The
junction box must NOT be located in the 6 o’clock position, as viewed from the motor end.)
3. Electrical connections – Observe all applicable codes when connecting to power supply. The motor is impedance
protected, and does not require overload protection. Either colored wire from the capacitor box can be attached to
either colored wire from the power supply. There is no “hot” or “common” wire leading from the capacitor box. Typical
installation would be to attach the white wire to the white (common) power supply wire and either the yellow or blue
wire to the black (hot) power supply wire. The pump cannot run backwards.
4. Fill system with tap water – The system must be filled before operating the circulator. The bearings are water lubri-
cated 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.
5. Circulator operation – Operate the circulator for 5 minutes immediately after filling system to purge remaining air from
the bearing chamber. This is especially important when installing the circulator during the off-season.
