Recommended Purging Steps:
1. Open fixture at highest point in system

Open all isolation valves
Once system is filled, close the fixture at

the highest point in the system
Close isolation valve on pump discharge

(Option No. 1 location)
Open drain valve on pump discharge until

all remaining air has been purged
Close drain valve
Operate pump until all remaining air is

purged from bearing chamber

WARNING: 

Do not use in swimming pool or spa areas. Pump has not been investigated for these applications.

AVERTISSEMENT : 

Ne pas utiliser dans une piscine ou un spa. La pompe n’a pas été étudiée pour ces applications.

CAUTION:

 The addition of petroleum based fluids or certain chemical additives to systems using TACO equipment voids the 

warranty. Consult factory for fluid compatibility.

ATTENTION :

 L’ajout de liquides à base de pétrole ou de certains additifs chimiques à des systèmes utilisant un équipement 

TACO annule la garantie. Consultez le fabricant pour connaître la compatibilité de liquides.

CAUTION: 

Installations at 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.

ATTENTION:

 Des installations à des altitudes de plus de 1600 mètres doivent présenter une pression de remplissage plus élevée 

de 20psi au minimum afin d’éviter toute cavitation ou flashing de la pompe. Une défaillance prématurée peut en résulter. Réglez 

la pression duréservoir d’expansion de façon qu’elle soit égale à la pression de remplissage. Un réservoir d’expansion d’une taille 

supérieure peut être nécessaire.
