Product overview
The POLYMETRON model 8544 is a cleaning system for electrodes. There are two models:
•Air or water electrode cleaning system: Models 8544.1 (220 V), 8544.2 (110 V) and
8544.3 (24 V). An electrovalve supplies air or water to the sensor tip. Refer to Figure 1.
•Chemical electrode cleaning system: Models 8544.4 (220 V), 8544.5 (110 V) and 8544.6 (24 V).
A twin chamber hose pump uses an air–instrument to supply a measured volume of a cleaning
fluid with a nozzle that is installed immediately below the sensor tip. Refer to Figure 2.
The manufacturer recommends that a junction box is used to connect the POLYMETRON
9500 series or SC200 controller to the system as shown in Figure 1 and Figure 2. Then, the cleaning
interval is configured at the controller. Refer to Replacement parts and accessories on page 16 for
ordering information.

Installation
WARNING
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
Installation guidelines
N O T I C E
Make sure to install the instrument vertically. Make sure that the distance between the instruments and the
cleaning container is less than 2 m (6.6 ft).
Make sure that hazardous fluids or fluids that can produce hazardous vapors are handled safely.
These fluids must be handled in accordance with local regulatory agency requirements on
permissible exposure limits.
Install the instrument:
• In a location with a flat surface to prevent the unit from movement
• In a location with minimum mechanical vibrations and electronic noise
• In a location where the power switch and power cord are visible and easily accessible
• In a location where there is sufficient clearance around it to make plumbing and electrical
connections
Keep the sample tubing as short as possible to minimize lag time. Keep the instrument away from a
heat source.

Electrical installation
D A N G E R
Electrocution hazard. Always remove power to the instrument before making electrical connections.
Wiring for power
D A N G E R
Electrocution hazard. Protective Earth Ground (PE) connection is required.
D A N G E R
Electrical shock and fire hazards. Make sure to identify the local disconnect clearly for the conduit
installation.
WARNING
Potential Electrocution Hazard. If this equipment is used outdoors or in potentially wet locations, a
Ground Fault Interrupt device must be used for connecting the equipment to its mains power source.
WARNING
Electrical shock and fire hazards. Make sure that the user-supplied power cord and non‐locking plug
meet the applicable country code requirements.
N O T I C E
Install the device in a location and position that gives easy access to the disconnect device and its operation.
Supply power to the instrument with conduit or a power cable. Make sure that a circuit breaker with
sufficient current capacity is installed in the power line. The circuit breaker size is based on the wire
gauge used for installation.
For installation with conduit:
• Install a local disconnect for the instrument within 3 m (10 ft) of the instrument. Put a label on the
disconnect that identifies it as the main disconnect device for the instrument.
• Make sure that the power and safety ground service drops for the instrument are 18–12 AWG and
the wire insulation is rated for 300 VAC or higher.
• Connect equipment in accordance with local, state or national electrical codes.
• Connect the conduit through a conduit hub that holds the conduit securely and seals the enclosure
when tightened.
• If metal conduit is used, make sure that the conduit hub is tightened so that the conduit hub
connects the metal conduit to safely ground.
For installation with a power cable, make sure that the power cable is:
• Less than 3 m (10 ft) in length
• Rated sufficient for the supply voltage and current. Refer to the requirements in Specifications
on page 3.
• Rated for at least 60 °C (140 °F) and applicable to the installation environment
• Not less than 18 AWG with applicable insulation colors for local code requirements
• A power cable with a three-prong plug (with ground connection) that is applicable to the supply
connection

Présentation du produit
Le POLYMETRON modèle 8544 est un système de nettoyage des électrodes. Il existe en deux
modèles :
•Système de nettoyage d'électrode à air ou hydraulique : modèles 8544.1 (220 V),
8544.2 (110 V) et 8544.3 (24 V). Une électrovanne conduit l'air ou l'eau jusqu'à la pointe du
capteur. Voir Figure 1.
•Système de nettoyage d'électrode chimique : modèles 8544.4 (220 V), 8544.5 (110 V) et
8544.6 (24 V). Une pompe tubulaire à double chambre utilise un instrument pneumatique pour
fournir une mesure de liquide de nettoyage, à l'aide d'une buse installée juste au-dessous de la
pointe du capteur. Voir Figure 2.
Le fabricant recommande l'utilisation d'un bornier de raccordement pour connecter le
POLYMETRON 9500 ou le transmetteur SC200 au système comme illustré en Figure 1 et Figure 2.
L'intervalle entre les cycles de nettoyages se configure ensuite au niveau du transmetteur. Référez-
vous à la section Pièces de rechange et accessoires à la page 31 pour les modalités de
commande.
