Installation
2 Pump Oil Level - Check the oil level in the pump crankcase (level with dot on sight
glass).
3 Pump Rotation - To check the rotational direction of the motor push the start button and
then stop button. This will momentarily power the pump motor. Confirm the correct
rotation of the pump as indicated by the rotation arrows on the both sides of the pump.
Pulley rotation should be anti-clockwise when viewed from the control panel side of the
unit. Incorrect rotation may be solved by interchanging any two phases of the supply to
the motor.
4 Controller Setup and check - To power up the controller ensure that the main isolator
and all the circuit breakers are switched on. Check the controller settings before
function testing. The controller display indicates the Measured Value (PV), Set Value
(SV) and run indication for the Auto tuning (AT), Output 1 and 2 (OUT1, OUT2) and
Alarm 1 and 2 (ALM1, ALM2). The display is used during setting to show parameters
and functions.
5 Changing Set Point – In local mode the set point is changed using the controller
interface by pressing the “Set” key to enter the SV Setting Mode and modify SV (set
point) value. Change the controller set point, using the <R/S key to select the digit to be
changed and the arrow keys to change the digit. (Determine the required outlet
temperature from section 3.1).
6 Parameter Setting Mode - Refer to the controller manual in Appendix B for parameter
detail, selection and operation.
7 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.
8 Pump Motor Start - 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 45 lit/min.
9 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.
10 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.
11 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 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.
12 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
