5. Fill Umbilical – Connect umbilical to HP water outlet port and open the salt water inlet
valve. Allow water to flow through the system until it flows out of the umbilical. Salt
water or fresh water may be used depending upon which is available.
6. Pump Motor Star t - Push the pump Start button, the pump will start running and
system pressure will rise to balance the pressure drop down the length of umbilical.
The flow rate will be approximately 30 lit/min.
7. Pump Flow Rate - The pump is a positive displacement type and the flow rate may
only be limited by an under-supply of water to the pump. To check flow rate, use an
inline flow meter on the outlet or collect the water from the output in a container of
known volume and measure the time it takes to fill this know volume.
8. Heater Bank Selection - Determine the temperature rise required through the unit to
provide the correct temperature of fluid at the user. Use the heater selection table, (See
Table 3.1 ), mounted on the panel door to determine which heater banks should be
used to achieve calculated temperature rise. Switch on the required heater bank
switches sequentially. Refer to trouble shooting if any fault lights illuminate during this
operation.
9. Monitor Performance - Monitor the unit inlet and outlet temperature and the
differential temperature rise. The outlet temperature should rise until the set point is
reached. As the outlet temperature approaches the set point the controller begins to
govern the process by activating the automatic dump valve. The process should
stabilize and accurately maintain the temperature differential provided that the inlet
flow rate and temperature is sustained and consistent. The inlet water pressure should
be a minimum of 3 bar and should be maintained during dumping of excess hot water.
10. Filter Check - Two water filters are provided to clean inlet water. One for operation and
the other for stand-by. The pressure drop across each filter should be between 0.5 – 1
bar. Check the pressure drop after running the unit for a 4 to 5 hour settling-in period.
The filter will trap all contaminants introduced into the system during installation and
