1. GENERAL INFORMATION, USES:

The circulating pumps are used for the transfer of liquid media

within a closed-looped hot-water heating or air-conditioning

hydronic system. They are designed as single or parallel

main/standby operation variable-speed pumps, where the speed

is regulated by an on-board electronic device. They are to be

used with a water or glycol/water mixture.

2. SAFETY:

These instructions should be studied carefully before installing or

operating 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 prod-

ucts. Failure to comply with safety precautions could cause per-

sonal injury or machinery damage.

3. PUMP DESCRIPTION:

The high efficiency, electronically commutated Viridian pumps

consist of two main parts, the centrifugal pump and the electronic

regulator. The hydraulic part is hermetically sealed from the motor

assembly and has no mechanical seals. Viridian pumps are pow-

ered by an ECM permanent magnet motor which does not consume

energy to magnetize the rotor, providing superior energy efficiency.

The ECM motor is run by an on-board frequency converter with

an integrated PFC (Power Factor Correction) filter. The converter

estimates current flow and head from the motor load, information

essential for differential pressure control.

4. PUMP INSTALLATION:

The Viridian pump is protected with a double box during shipping.

It can be lifted from the box with internal handles or by lifting it by

the heat sink.

Pumps are designed to be installed using standard ANSI class

125 flanges. It is recommended that the Viridian pumps be

installed with at least 5 to 10 pipe diameters of straight pipe on

the inlet and outlet of the pump. Use all nuts and bolts to attach

companion flanges to the pump flanges. For pumps to operate

with minimal vibration and noise, it should be installed with the

axis in a horizontal position (see Figure 1).

Desired head orientation can be achieved by rotating the pump

head. The pump is mounted to the volute with four screws. By

unscrewing those the head can be turned. Caution: When

reassembling, care should be taken to avoid damaging the O-

ring and insuring a tight seal. For replacement O-rings, use part

number 975-001RP. See detailed Motor Rotation Procedure 4.1

below.

CAUTION: Use supply wires suitable for 90°C.

ATTENTION: Employer des fils d’alimentation

adeqauts pour 90°C.

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.

CAUTION: The addition of petroleum based fluids

or certain chemical additives to systems using

TACO equipment voids the warranty.

ATTENTION: L'ajout de liquides à base de pétrole

ou de certains additifs chimiques à des systèmes

utilisant un équipement TACO annule la garantie.

WARNING: Hot surfaces can cause burns. The

motor can also reach temperatures that could

cause injury.

AVERTISSEMENT: Les surfaces chaudes peuvent

provoquer des brûlures. Le moteur peut également

atteindre des températures qui peuvent entraîner

des blessures.

CAUTION: Pump motor, electronics enclosure and

condensate drain openings should not be thermally

insulated as it could interfere with cooling and

condensate drainage.

ATTENTION: Le moteur de pompe, l'enceinte élec-

tronique et les ouvertures de drainage de condensat

doivent être thermiquement isolés car il peut y avoir

interférence avec l'évacuation de condensat et de

liquide de refroidissement.

CAUTION: Misconnection or overload of electrical

or signal connections could cause pump to shut-

down or cause permanent damage.

ATTENTION: Toute erreur de raccordement ou sur-

charge des connexions électriques ou de signali-

sation peut entraîner un arrêt de la pompe ou des

dommages permanents.

CAUTION: Do not operate pump without the electri-

cal cover securely attached.

ATTENTION: Ne pas actionner la pompe si le cou-

vercle électrique n'est pas correctement fixé.

CAUTION: Pump may be heavy. Provide yourself

help if needed.

ATTENTION: La pompe est lourde. Veillez à deman-

der de l'aide si nécessaire.

The pump has built-in over current fuse protection, temperature protection and basic overvoltage protection. It does not require additional overload protection devices unless required by local electrical codes. Power supply cabling should be capable of carrying rated power and be properly fused. Ground lead connection is essential for safety and should be connected first. Grounding is only meant for pump safety. System piping should be grounded separately. A ferrite core is supplied in a separate bag.

.3 Constant Duty Curve (Unregulated Pump) Control: An unregulated pump CONSTANT decreases its head with H DUTY increasing flow. This unregCONTROL ulated setting can be achieved by setting the limit head (Hmax) to “no Max RPM or Unregulated Curve limit (99)” in the pump tab (see below) with a jumper across IO2/24V (or 8Vdc Reduced RPM and above). Note: I1 must Curves be closed and set to "no function". Limit rpm to should be set to the maxiQ mum value to achieve full pump curve.
