DEFASM Engine Heater (X2 Models) (If Equipped)
Only connect the DEFASM engine heater to a grounded socket.
Only a DEFASM connection cable must be used for the DEFASM WarmUp system.
Power Off and On will either be controlled by the DEFASM WarmUp control unit or manually using the connection cable.
When connecting the connection cable, the vehicle socket must always be connected first before finally connecting the plug to a grounded 230V AC socket.
DEFASM engine heaters are designed for normal use. DEFASM defines normal use as 3 connections for 3 hours per 24 hours based upon 150 days per year (5 months a year).
When the DEFASM engine heater is used in application where it is switched on and off x number of times per hour, its lifetime will be reduced significantly.
