shown in "Condensate overflow safety switch connection (CN4F)" section.
CAUTION
When installing the float switch, consider the following potential water leakage issues:
• between the SS2 housing and SS2 coupling
• between the drain pan screw and SS2 coupling
Refer to www.rectorseal.com for float switch WARNING, CAUTION and NOTICE, prior to
float switch installation. Float switch is made of PVC . Extremely high furnace discharge
temperature may cause damage to the float switch. Mitsubishi Electric US, Inc. is not
responsible for float switch damage caused by gas furnace heat.
If extension is added to the drain pipe, ensure that the float switch can safely detect
overflow conditions. If float switch water detection level is higher than drain pan overflow
level, Mitsubishi Electric US, Inc. is not responsible for water leak or gas furnace damaged
problems, caused by water leak from the PAA unit.
Specifications are subject to change without notice.
