Page 17: Other Applications
INSTANTANEOUS HOT WATER APPLICATIONS. When water is being drawn directly from the Econoplate into the distribution system to the taps this is termed instantaneous hot water generation. The cold water feed connection is made into the bottom horizontal bronze connection on the rear of the Econoplate. - Page 18 SECONDARY INSTALLATION DETAILS. Instantaneous Application.

Page 20: Operation
OPERATION. Prior to switching the Econoplate on it must be ensured that the unit is filled with water and that all pipework and pumps are vented. Once this is complete and the unit is on, the Econoplate Controller should be set up as described in the Econotrol 2100 Controller Manual to suit the particular requirements of the client. - Page 21 AVM124 actuators also have a switch coding for valve speed inside the actuator cover, which can be seen through the clear lid, and these should be set as below. There is also a single green LED just below the switch box which gives indication of the following functions of the actuator.
- Page 22 AVM234 actuators also have switch coding for the actuator/valve speed and characteristics (which are on the inside the actuator terminal box) should be as below. AVM234 actuators have the following indicators on the outside of the actuator assembly whilst in operation.

Page 23: Maintenance
MAINTENANCE. If the installation is set up as per the above instructions, and if the pre-set factory values are unchanged, the Stokvis Econoplate Unit should not need dismantling for service for many years. Any clogging, may be detected as follows: - A high pressure drop between inlet and outlet of the secondary hot water circuit. - Page 24 A visual check on the correct assembly can be made by looking at the edge of the plates. A pattern resembling a honeycomb should always be seen. Plates can be identified in the following way. G30 all have gaskets on one side of each plate facing the fixed chassis. G30 have octagonal gaskets around the ports and the corner of the plate is cropped at 45 GL13 have round gaskets around the ports and have the corner of the plate is...

Page 25: Fault Finding
FAULT FINDING. E SERIES PLATE HEAT EXCHANGER FLUCTUATING TEMPERATURES AT OUTLET. Check that the secondary pump is operating correctly and that good circulation exists - feel the temperature of the return pipe, if it is cool then there is no circulation. Check that a non-return valve is fitted on the HWS return and that it is not letting by and so allowing the cold feed to pass up the HWS return - feel for a cool return pipe. - Page 26 Check to ensure correct connection of valve and actuator as described previously in the Operation section. Check that the valve motor is operating - raise and lower the set point on the controller and observe. - If the motor does not work, perform the procedure above for the temporary hot water supply.
- Page 27 Ensure that there is an electrical supply to a primary pump and link the start/stop terminals for that pump if not already made. Reduce the boiler flow temperature to a maximum of 65°C to prevent excess secondary temperatures. Set the high temperature alarm to automatic - refer to “Econotrol 2100 manual” for procedure.
