Introduction
This manual is broken down into two sections and describes the instal-
lation, operation and control module for 1900e series pumps. Section 1
describes the installation and operation features. Section 2 describes the
control module and its functions.
1 - General Information Uses
The 1900e series circulating pumps are available in 2 versions. The ductile
iron version is used for the transfer of liquid media within a closed-loop
hot-water heating or air-conditioning hydronic system. The stainless steel
version is used in potable DHW systems or where NSF/ANSI 61 & 372
compliance is required.
Both the ductile iron and stainless steel versions are designed as single or
parallel main/standby operation variable-speed pumps, where the speed
is regulated by an on-board electronic device.

2 - Safety

These instructions should be studied carefully before installing or oper-
ating the pump. They are meant to help you with installation, use and
maintenance and to increase your safety. Installation should be performed
with regards to local or national standards. Only qualified personnel should
maintain and service these products. Failure to comply with safety precau-
tions could cause personal injury or machinery damage.
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.
Warning: To avoid electrical shock, disconnect the
power supply to the circulator and the main electrical unit.
Follow all local electrical and plumbing codes.
AVERTISSEMENT: Pour éviter tout choc électrique,
débranchez l'alimentation électrique vers le circu-lateur
et l'unité électrique principale. Respectez tous les codes
de plomberie et électriques locaux.
Warning: Hot surfaces can cause burns. The motor
can also reach temperatures that could cause injury.
AVERTISSEMENT: Les surfaces chaudes peuvent provo-
quer des brûlures. Le moteur peut également atteindre des
températures qui peuvent entraîner des blessures.
Warning: The addition of petroleum based fluids or certain
chemical additives to systems using TACO equipment voids
the warranty.
AVERTISSEMENT: L'ajout de liquides à base de pétrole
ou de certains additifs chimiques à des systèmes
utilisant un équipement TACO annule la garantie.
Warning: Use supply wires suitable for 90°C.
AVERTISSEMENT: Employer des fils d'alimentation
adeqauts pour 90°C.
Warning: Misconnection or overload of electrical or signal
connections could cause pump to shut-down or cause
permanent damage.
AVERTISSEMENT: Toute erreur de raccordement ou
surcharge des connexions électriques ou de signali-sation
peut entraîner un arrêt de la pompe ou des dommages
permanents.
Warning: Do not operate pump without the electrical
cover securely attached.
AVERTISSEMENT: Ne pas actionner la pompe si le
couvercleélectrique n'est pas correctement fixé.
Warning: Pump motor, electronics enclosure and conden-
sate drain openings should not be thermally insulated as it
could interfere with cooling and condensate drainage.
AVERTISSEMENT: Lemoteur depompe, l'enceinte
électronique et les ouvertures de drainage de
condensat doivent être thermiquement isolés car il
peut y avoir interférence avec l'évacuation de
condensat et deliquide de refroidissement.

3 - Pump Description

The high-efficiency, electronically commutated, close coupled 1900e
series pumps consist of two main parts; the centrifugal pump and the
electronic control. The hydraulic section is sealed from the motor assembly
by a mechanical seal. 1900e series pumps are powered by a permanent
magnet electronically commutated motor (ECM) which does not consume
energy to magnetize the rotor, providing superior energy efficiency.
The ECM is run by an on-board frequency converter. The converter
estimates current flow and head from the motor load and speed. With
this information the self-sensing ECM pump constantly calculates pump
head and flow and adapts motor speed to the appropriate flow for the
selected curve.

3.1 - Features

• 10 easy to set modes to match system requirements:
º 4 - Constant Pressure modes
º 3 - Constant Speed modes
º 1 - Proportional Pressure mode
º 1 - 0-10v mode
º 1 - 2-pump operation mode
• ECM performance equivalent to the versatile 1900 & 1600 series
pumps.
• Fully rotational User Interface (UI) to accommodate any pump position.
• LED Status monitors Pump On (solid green), Pump in Standby (flashing
green) and Error (flashing red error code - see section 22.1)
• Mechanically sealed for easy maintenance.

4 - Use

All 1900e series pumps equipped with a ductile iron casing are intended
for circulation of solid-free fluid in pressurized, hot and chilled hydronic
systems. All 1900e series pumps equipped with a stainless steel casing
are intended for DHW and potable water applications and are NSF Com-
mercial Hot (180°F water) rated and suitable for sanitizing applications.
