Garcia, Engineer Review Level: 3 Administrative Support: Leslie Oulashian, Management Analyst II Section 303.015 Page 1 of 5 PURPOSE The purpose of this procedure is to provide information and operational procedures for the Hale EZFill Foam Tank Refill System for Fresno Fire Department (FFD or Department) members. APPLICATION FFD Brush Engines are equipped with the Hale EZFill Foam Tank Refill System. OPERATIONAL POLICY This section intentionally left blank. OPERATIONAL GUIDELINE This section intentionally left blank. PROCESS 1. Operation: The EZFill system should receive power from the down side of the main disconnect of the apparatus and is always operable while power is supplied to the pump panel. a. To fill the foam tank: i. The switches on the smart-switch controller illuminate (white) to indicate the system is operational. Section 303.015 Page 2 of 5 ii. Connect the suction hose to the quick disconnect adapter on the operator panel and assure a tight seal. iii. If not already installed, slide the strainer on the end of the suction tube until the tube bottoms within the strainer. iv. Fully insert the tube into the foam bucket. (usually a 5- gallon container) v. Press and release the FILL button to begin the tank fill process. The CLASS1 will light when the fill pump/motor is running. The pump/motor runs for approximately sixty seconds or until the tank FULL sensor is activated, indicating a full tank. vi. As the foam container empties, replace the container and repeat step 6 until the tank is full. vii. To FORCE FILL the tank, press and hold the FILL button. The foam pump/motor runs continuously until the button is released. 1) In the FORCE FILL mode, an operator must always be available to monitor the capacity of the tank to avoid an overfill condition. 2. Flush Operation: a. Connect the suction hose to the quick disconnect adapter on the operator panel and assure a tight seal. b. Fully insert suction tube into container of clean, fresh water. i. Pump flow rate is approximately 10.5 gpm. Therefore, a 30 second flush cycle requires just over 5 gallons of water. c. Place the FLUSH discharge hose into an empty container or discharge to the ground. d. Press and release the FLUSH button to begin flowing fresh water throughout the system for approximately 30 seconds i. CLASS1 will light when the fill pump/motor is running. Section 303.015 Page 3 of 5 e. As the clean water container empties, replace the container and repeat step 5 until all signs of foam residue are flushed from the system. f. To force flush the tank, press and hold the FLUSH button. The foam pump/motor runs continuously until the button is released. 3. Routine Maintenance: The unique design of the Hale EZFill system makes it virtually maintenance free. However, as with any electromechanical system, periodic inspection and lubrication is required to ensure a long, trouble free life. a. After each use: i. Flush EZFill system with fresh water. ii. Visually inspect the 3 position valve to insure there is no debris caught between the valve body or valve ball. iii. Cycle the 3-position valve to verify it operates smoothly. Apply an approved lubricant to the valve if necessary. b. Monthly: i. Cycle the 3-position valve from fully closed to the fully opened position, noting the torque required to operate the valve. If excessive resistance is noted, contact the shop for trouble shooting the valve. INFORMATION The Hale EZFill Foam Tank Refill System is an electronically controlled, easy to operate, fixed mount, 5 gpm foam tank refill system. It features the Class1 push button Smart Switch technology, interconnecting wire harness, motor/pump and valve assembly. The EZFill system is self-priming and automatically shuts off after sixty seconds or when the foam concentrate reservoir is full.
