not be rendered inoperable during the cleaning process.
Care shall be taken not to apply cleaning chemicals on fusible links or other detection devices of the automatic extinguishing system.
When cleaning procedures are completed, all electrical switches and system components shall be returned to an operable state. All access panels and/or doors and cover plates shall be replaced. Dampers and diffusers shall be positioned for proper airflow.
D.Water Wash System – every 4 to 6 months
The water wash spray pattern should be checked on each nozzle to ensure that a full spray pattern is developed. Distorted patterns are usually caused by dirt in the nozzle orifice, which can be cleaned by inserting a small gage, soft copper wire into the orifice. If any one manifold contains several nozzles that are restricted, the drain plug at the idler end of the manifold should be removed, after the nozzles have been cleaned, and the manifold flushed with clean water. The main supply line strainer and the strainer in the detergent system should be checked and cleaned. Check the wash manifold drive belt and linkage connections and replace or tighten as required.
WARNING:
DO NOT USE HIGH PRESSURE STEAM CLEANING EQUIPMENT TO CLEAN CELLS. THE EXCESSIVE HEAT AND PRESSURE WILL CAUSE THE PLATES TO WARP AND IN TURN POSSIBLY CAUSE EXCESSIVE ARCING.
E.Power Supply(s) and Control every 12 months Examine the electrical components located inside the control housing for any accumulated dirt or dust. If necessary, clean with a good brand of electrical contact cleaner.
F.Blower Bearings - every 4 to 6 months
Grease the two blower bearings at the grease fitting provided with Shell Alvania #2, Texaco Multifac #2 or Mobilux #2. At this time, examine the blower for any accumulated dirt and clean as required.
G.Motors – every 24 months
As the operation of detergent pump motor is limited, frequent oiling is not required. Lubricate with several drops of SAE 10 motor oil every two years. DO NOT OVER OIL. The manifold drive, detergent pump and blower motors have sealed bearings, are factory lubricated for life and require no oiling.
