5.1.2 The exterior of the controller and CPR assembly should be
periodically wiped down with a cloth dampened with disinfectant.
CAUTION! DO NOT spray disinfectant directly on the
electrical controller, or immerse the controller in any type of
liquid. This could result in a severe electrical hazard.
5.1.3 Before plugging in the controller, check the power cord for
electrical hazards, e.g., cuts, exposed wires, worn insulation, etc.
If hazards are present, take the controller out of operation
immediately and contact Tridien Customer Service at 800-474-

Contact Tridien Customer Service for calibration and Bio-Med
information. Tridien will provide one free Bio-Med test.

1. Unplug the electronic controller.
2. Remove the filter grill cover and remove the filter. DO NOT
