V8043A E F 5000 Series VALVES These valves consist of a motorized and valve assembly for controlling flow of hot water to a heat exchanger as a radiator convector finned radiator or infloor radiant coil space temperature control The V8043 series valves provide two position through control of supply water at to 300 psi operating pressure Quick Fit actuator provides easy snap on and connection to the valve assembly Electrical Rating 60 Hz 0.30 A Current Draw W 7.2 VA maximum Connection leads or screw terminal board Switch Rating 4.4A running 26.4A Inrush 60 Hz VA Pilot duty at 24 V Temperature

electrical or equipment damage 2 Normally it is not necessary to remove actuator from the valve body during If the valve must be be certain that it is with the water flow in the of the arrow Reversal of the results in damage to the gear 3 On 24V systems never jumper the coil terminals even temporarily can burn out the heat anticipator in thermostat Installing this Product 1 Read these instructions carefully Failure follow them could damage the product cause a hazardous condition 2 Check the ratings given in the and on the product to make the product is suitable for your 3 Installer must be a trained experienced technician 4 After installation is complete check out operation as provided in these Install the valve in an area with adequate to Move the manual opening lever on the of the actuator Remove the actuator cover Wire the actuator Replace the actuator motor The valve location should be in an area the temperature does not exceed the valve operating ambient and fluid temperatuare Lever V8043 normally closed valves can be manually by moving the manual lever and firmly to the MAN OPEN position pushing up to the stop The stop permits valve to be locked in the open position valve returns to automatic position when is energized Printed in Canada No 95C 10932 The valve can be mounted in any position a vertical line See Fig 2 If the valve is horizontally the actuator must be with or above the center line of the Make sure to leave enough room the actuator to remove the cover for the valve directly in the tube or pipe the coil Make sure that the flow the valve is in the direction by the arrow stamped on the body 2 Mounting Positions Copper Models Use new properly reamed pipe free dents or corrosion Place the valve on the pipe Set the opening lever to MAN OPEN before applying heat This the plug inside the valve by it from the seat Sweat the joints keeping the outer free from solder DO NOT use solder because of the high temperature required INSTALL A COMPLETE VALVE V8043 Disconnect power supply before wiring to prevent electrical or equipment damage Install valve into pipe on the return side the coil See Mounting Section Make wiring connections to valve Refer Wiring section for proper instructions Inspect the valve installation to ensure all connections and adjustments been correctly made Adjust the or controller connected to the so that the valve runs through its Make sure the valve runs and positively from closed to to closed again See Operation Checkout Sections REMOVE THE ACTUATOR FROM THE BODY See Fig 3 is not necessary to drain the hydronic if the valve body assembly remains in pipe line Switch power supply OFF Disconnect leads carefully noting the and colour of each lead Place the manual lever in the MAN position Remove
