Installation
and should be regularly checked after set-up. Replace/rinse the filter elements when
the pressure drop rises above 1.2 bar.
13
Current Drawn - Check input current and voltage to make sure acceptable limits are
maintained.
14
Process Control - When the unit is set-up and operating properly with the correct
heater selection and supplies it will deliver water heated to within ± 1ºC of the controller
set point. Confirm that the unit controls the process as specified.
SYSTEM FLUSHING
When the system is not in use it should be thoroughly flushed with fresh water and
completely drained according to the Shutdown Procedure detailed in section 3.5.
Note
When diving in dirty water it may be necessary to pre-filter the water supply to the
water heater to 100 micron, or less to ensure satisfactory performance and
manageable filter element changeovers.

Start Up and Function Check – Remote Control
The function of the WHE-3 remote control must also be thoroughly checked prior to being put
into service. This should be done after the start up and function checks on the WHE-3 unit
have successfully been completed. The following procedure outlines the steps used in
conducting remote control start-up and functional checks.
1
Remote Emergency Stop – Test the function of the remote emergency stop with the
WHE-3. Activation of the remote emergency stop will remove power from the main
control circuit, stop the pump motor and de-energize the heater banks. The heater
banks will remain selected as the rotary selector switches are not reset. An alarm will
be generated and the general fault on the remote panel will illuminate in addition to the
indication on the local control panel.
2
Remote Pump Run Indication – Check that pump run indication illuminates when the
pump motor is running and is extinguished when it is stopped normally.
3
Remote General Fault Indication – The general fault indication on the remote control
panel will be illuminated when the pump trip, over-temperature or low level fault
indication is present on the local control panel.
4
Remote Temperature Display – The remote temperature display is calibrated during
factory testing. Calibration should be confirmed by comparison of the remote display
indication against the local controller indication.
5
Remote Control Selection (Remote vs. Local) – Remote fine control is selected using
the temperature controller in the WHE-3 electrical panel. Refer to the temperature
controller manual for details on switching between local and remote set point input,
Refer to the temperature controller manual in Appendix B.
6
Remote Set Point Potentiometer Calibration – The potentiometer is a 0 - 10 V output
signal generator. The output bias and ratios are set so as to match the temperature set
points and range indicated on the remote panel faceplate, i.e. 35 to 65ºC.
