Page 7: How It Works
HOW IT WORKS DeltaPoint Jr. is a cooling water flow switch. It is comprised of a flow sensor, a shut-off valve, a check valve, and all the associated wiring, complete in one package. When installed in the return leg, it can detect changes in water flow due to cap loss or a break in the line, and shut off the supply/return water legs. -
Page 8: Installation
ROCON LLC INSTALLATION There are no upstream or downstream piping requirements to achieve proper operation. Refer to page 22 to review requested water flow test using 90 degree elbow. The unit should be installed on the fence line for best results. The unit can be installed in any position as long as good piping installation requirements are adhered to. -

ROCON LLC SET-UP PROCEDURE Configuring the Engineering Units In order to configure the engineering units (GPM or LPM), proceed as follows: 1. Press and hold the MENU pushbutton, the display shows “---”. Continue holding the pushbutton for at least 5 seconds. - Page 12 ROCON LLC Note: Flow fault occurs when flow =< setpoint. The LED display starts blinking to indicate this. After the occurrence of a flow fault, the unit must be restarted. If in bypass mode, the alarm signal returns to normal when flow > setpoint + hysteresis (display stops blinking).

ROCON LLC Check to determine if air is trapped in the cooling water circuit. Remove the hoses TO CELL and FROM Cell. Attach a 5-foot plastic (see-through) loop hose between TO CELL and FROM CELL on the unit. Power up the unit. Use a flashlight to look through the plastic hose and see if air bubbles are present in the water line. -
