Integration Constraints - Pentair AUTOTROL MAGNUM 293 Installer Manual

• temperature — Extreme hot or cold temperatures may cause damage to the valve or
controller. Freezing temperatures will freeze the water in the valve. This will cause physical
damage to the internal parts as well as the plumbing. High temperatures will affect the
controller. The display may become unreadable but the controller should continue to
function. When the temperature drops back into normal operating limits the display will
return to normal. A protective cover (P/ N 1267811) should assist with high temperature
applications;
• insects — The controller and valve have been designed to keep all but the smallest insects
out of the critical areas. Any holes in the top plate can be covered with a metal foil ductwork
tape. The top cover should be installed securely in place;
• wind — The Logix cover is designed to withstand a 48 km/h wind when properly installed on
the valve.
