Installation
2.4.1
Fluid System Priming Procedure
After the electrical and pipe work installations have been completed, purge the piping system
of air in order for the pumps to function properly and for the electric heater elements to be fully
immersed.
LOW WATER LEVEL OPERATION
The equipment may be severely damaged if heaters are supplied with power when
there is no water in the system.
Use the following procedure to correctly prime the system:
1
Open the salt or fresh water input valve slightly to allow water to flow into the system.
Water supply should be at sufficient pressure (3 bar minimum).
2
Check that all the ball valves on the filters are open.
3
With the vent valve on top of the level control tank open, leave the water supply on until
water flows out of the vent tube.
4
Close the vent valve and wait for water to flow through the pump and out of the HP
water outlet fitting.
5
Allow the water to run for 5 to 10 minutes in this mode.
6
Confirm that the heater tank is full by opening the tank vent valve to purge any residual
bubbles in the heater tank.
7
To complete priming shut the vent valve and supply valve(s).
2.5
Start Up and Function Check – Local Control
After installation is complete the WHE-3 must be thoroughly checked prior to being put into
service. The following procedure outlines the steps used in conducting a comprehensive
start-up and functional check. Ensure that the controller is set in local control mode and carry
out all local control checks before commencing remote control checks. Refer to the
temperature controller manual in Appendix B for detail on how to switch between remote and
local operation switching.

Power Supply - Turn on the mains power to the unit. Input power must be as defined at
Paragraph 2.3.
FAULT INDICATION
The system will be prevented from being started if faults are indicated. Press the fault
reset button to clear any fault indication.
If fault indication is not reset or the fault recurs refer to troubleshooting for corrective
action.
