F263 Series Liquid Level Switches Installation Instructions
Applications
The F263 Series Liquid Level Switches are designed to maintain a liquid level in indoor or outdoor closed tanks
holding water or other non-corrosive liquids. When the liquid level in the tank rises above or falls below the required
level, the SPDT switch closes one circuit and opens a second circuit.
Use F263 Series Liquid Level Switches in closed tanks where a liquid level is to be maintained. A change in the
liquid level opens or closes an electrical circuit.
Use F263MAP switches on indoor or outdoor tanks that hold water or other nonhazardous liquids at temperatures
greater than the liquid's freezing point and between -20°F (-29°C) and 212°F (100°C). The maximum allowable
liquid pressure is 150 psig
(1035 kPa).
Use F263MAC switches on indoor or outdoor tanks that hold water or other nonhazardous liquids at temperatures
greater than the liquid's freezing point and between -20°F (-29°C) and 250°F (121°C). The maximum allowable
liquid pressure is 100 psig (690 kPa).
Note:
Do not use these liquid level switches with liquids with a density less than the density of water.
IMPORTANT:
Use this F263 Series Liquid Level Switch only as an operating control. Where failure or
malfunction of the liquid level switch could lead to personal injury or property damage to the controlled equipment
or other property, additional precautions must be designed into the control system. Incorporate and maintain other
devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against
failure or malfunction of the liquid level switch.
IMPORTANT :
Utiliser ce F263 Series Liquid Level Switch uniquement en tant que dispositif de régulation.
Lorsqu'une défaillance ou un dysfonctionnement du liquid level switch risque de provoquer des blessures ou
d'endommager l'équipement contrôlé ou un autre équipement, la conception du système de contrôle doit
intégrer des dispositifs de protection supplémentaires. Veiller dans ce cas à intégrer de façon permanente
d'autres dispositifs, tels que des systèmes de supervision ou d'alarme, ou des dispositifs de sécurité ou de
limitation, ayant une fonction d'avertissement ou de protection en cas de défaillance ou de dysfonctionnement
du liquid level switch.
IMPORTANT:
Do not use F263MAC and F263MAP Liquid Level Switches where the fluid in the pipes drops
below the fluid’s freezing point, causing an internal freeze-up.
IMPORTANT:
Do not use F263 Series Liquid Level Switches with hazardous fluids or in hazardous
atmospheres. Use in these conditions may cause malfunction or improper operation.
This product is made of a copper alloy, which contains lead. The product is therefore not to be used on drinking
water.
