FOIRE AUX QUESTIONS - CF Plus STIEBEL ELTRON

Comment installer le chauffe-eau CF Plus ?

L'installation doit être effectuée par un électricien qualifié conformément aux normes locales. L'appareil nécessite une alimentation triphasée (208/240/480/575 V) et un raccordement d'eau avec des vannes à bille fournies. L'enceinte NEMA 3 est conçue pour une installation intérieure ou extérieure.

Quelle est la consommation électrique maximale ?

La consommation dépend de la puissance du modèle. Par exemple, un modèle de 144 kW sous 480 V triphasé tire 173 A en pleine charge. Chaque résistance est protégée par un fusible individuel et l'appareil est pré-câblé.

Comment régler la température de sortie ?

La température se règle sur la carte électronique PCB à l'intérieur de l'enceinte, par incréments de 1 °F (de 60 à 180 °F). Les modèles CF Plus n'ont pas d'interrupteur externe ; le réglage se fait directement sur la carte.

Que faire en cas de panne ou d'absence d'eau chaude ?

Vérifiez d'abord les disjoncteurs et les fusibles. Assurez-vous que le débit d'eau est suffisant (activation à 0,75 GPM minimum). Si le problème persiste, contactez un professionnel agréé. L'appareil est équipé de multiples protections de sécurité.

Comment entretenir le CF Plus ?

Un entretien régulier consiste à nettoyer l'extérieur de l'enceinte avec un chiffon doux et à vérifier périodiquement les connexions. Il n'est pas nécessaire d'entretenir l'intérieur, mais une inspection par un professionnel est recommandée tous les 2 ans.

Le chauffe-eau est-il protégé contre le gel ?

Oui, la protection antigel est intégrée en standard. Elle permet d'éviter les dommages en cas de températures négatives, mais l'appareil doit être alimenté en eau et en électricité pour fonctionner.

Quelle est la durée de vie typique ?

La durée de vie n'est pas spécifiée, mais avec un entretien approprié et une installation correcte, ces chauffe-eau commerciaux peuvent fonctionner pendant de nombreuses années. La garantie de 6 ans sur l'échangeur témoigne de leur robustesse.

Peut-on utiliser le CF Plus pour une douche de sécurité ?

Oui, il convient aux applications de douche de sécurité, mais un mélangeur peut être nécessaire pour respecter les normes OSHA (température entre 60 et 90 °F). Les modèles CES Plus sont spécifiquement conçus pour cet usage.

Quels sont les modèles de la série Plus ?

La série Plus comprend quatre gammes : CF Plus (démarrage à chaud), CE Plus (démarrage à froid avec réglage externe), CES Plus (pour douches de sécurité) et CERO Plus (résistances en titane pour fluides caustiques). Chacune a des caractéristiques spécifiques.

Où trouver des pièces détachées ?

Les pièces détachées sont disponibles auprès de Stiebel Eltron ou de ses distributeurs agréés. Contactez le service commercial au 800-TANKLESS ou par email à [e-mail].

C Series Commercial/Industrial 3-Phase Electric Tankless Water Heaters

C Series 3-phase electric tankless water heaters are designed to provide hot water for commercial and industrial use. Tankless water heaters do not store hot water as a tank water heater does, but make it on demand as it is needed. There are several major benefits of tankless water heaters over tanks because of this difference.

First, a tankless water heater never runs out of hot water. As long as it is needed, a tankless water heater will make and deliver hot water at the specified set point temperature. Second, tankless water heaters are not storing hot water, and they have no standby heat losses. This results in energy savings on the order of 20% over an electric tank. The exception is hot-start tankless models like our CF Plus, but their standby heat loss is minimal when compared to the extensive surface area of a standard tank. And third, tankless water heaters are considerably smaller than a tank, saving space, and are not prone to leakage. Electric tankless water heaters also do not need venting.

CF Plus | General Purpose Water Heaters

CF Plus models are electronically-controlled, hot-start models that will deliver immediate hot water. When shipped they are set to output hot water at a single temperature specified when ordering. Output temperature can be easily adjusted on the printed circuit board, but CF models lack an external toggle switch to make a temperature adjustment. CF Plus models are accurate to ±1.5^ F at low flow rates. They are used for applications where continuous delivery of hot water is demanded and an immediate start is important. Typical applications include circulation systems, boiler replacement, process manufacturing, and cleanup. CF Plus models can also be used in safety shower applications, but a mixing valve may need to be installed.

CES Plus | Eyewash & Emergency Shower Water Heaters

CES Plus models are designed to heat water for emergency eyewash/face wash stations and emergency drench showers to meet OSHA requirements. The CES Plus has the same operation, capacity, and voltage ranges as the CE Plus series. It differs from the CE Plus by limiting temperature control to 60-90°F and using a 180°F manual-reset safety cut-off.

CES Plus 12 kW through CES Plus 36 kW units should be used solely for eyewash station applications. Depending on size, they will heat up to 7 gallons per minute by 35°F (20°C) and limit the output temperature to OSHA requirements. CES Plus 60 kW through CES Plus 144 kW units will meet OSHA requirements for many installations including emergency drench showers.

Incoming water temperature must be measured on a cold day to verify the kilowatt size needed to comply with emergency shower and eyewash/face wash requirements. Only the largest models will be sufficient for cold temperate climates. We recommend targeting 85°F for best results. To meet regulations 60°F must be attained. Regulations also require at least 20 GPM per minute per shower for 15 minutes to comply, plus eyewash/face wash station requirements.

Features

• Meets all OSHA and ANSI Z 358.1 requirements
• Minimum activation rate of 0.75 gpm
  Output temperature range 60-90° Fahrenheit
• Rocker switch on outside of enclosure adjusts temperature in increments of 1° Fahrenheit
• Individually fused element circuits
• 840 Incoloy sheathing material for the elements
• Temperature of output water and set point temperature both displayed behind front panel window

CERO Plus | Caustic Fluid Heaters

CERO Plus models are designed to heat reverse osmosis (RO) water and caustic fluids. They have corrosion-free titanium-sheathed elements that will last longer in a caustic environment than standard Incoloy-sheathed elements. CERO Plus has the same electronic operation as the CE Plus series, calculating the amount of energy needed to meet hot water demand, then activating the minimum number of elements necessary to satisfy that demand, depending on flow rate and temperature measurement. No energy is used when the unit is idle other than the indicator light.

Features

• Minimum activation rate of 0.75 gpm
• User set output temperature 60–180° Fahrenheit
• Rocker switch on outside of enclosure adjusts temperature in increments of 1° Fahrenheit
• Individually fused element circuits
• Titanium-sheathed elements for resistance to caustic fluids
• Temperature of output water and set point temperature both displayed behind front panel window

Options

- NEMA 4 and NEMA 4X enclosures are available NEMA 4X is recommended for highly corrosive environments.
