Horizon Reverse Osmosis Seafari Escape 200, Owner'S Manual

11. Open any auxiliary valve within the incoming feed line, Outgoing Brine Discharge Line and Outgoing
Product Water Line.
Caution: Any auxiliary valve in these lines damages the Horizon Reverse Osmosis System
if left closed during starting and/or operation of the system.
12. If the optional Clean Rinse Valves are installed, ensure that they are positioned properly for normal
operation.
13. Switch the electrical power source to the “ON” position, the boat’s circuit breaker.
14. Perform a booster pump motor rotational check. Ask an assistant to view the fan chapter of the
Feed Water Pump Motor while “jogging” this electric motor.
Press the “START/STOP” switch; then immediately after the booster pump starts, press the
“START/STOP” switch. Ensure that the Feed Water Pump Electric Motor is turning in the proper
rotation.
To change rotation in DC systems, reverse polarity to the electric motor by interchanging the positive
and negative power leads to the motor. Then check the rotation again to ensure proper rotation.
Caution: The booster pump is a very close tolerance vane pump. It requires water for
lubrication. Operating this pump dry will damage it within 30 seconds. Prime the system
with water up to the booster pump inlet to ensure that it is wet prior to starting.
15. To start the system, press, the “START/STOP” switch. If the system automatically shuts off
immediately or after 20 seconds of operation, this may be due to a system fault. Look at the touch
pad to confirm whether a fault has occurred. If the “High-/Low-Pressure” Fault Lamp is illuminated,
ensure that the system feed line is primed and that there is no air in the feed water line. Press the
Fault Reset button on the touch pad and restart the system. Initial new system commissioning may
require priming of the feed water up to the Booster Pump inlet and through the prefiltration chapter
in order to build sufficient feed water pressure to maintain operation.
a) Low Pressure Fault
The Low-Pressure Switch is a normally open switch that closes at 40 PSI or greater pressure.
The Low-Pressure Switch must receive a minimum of 40 PSI line pressure in order for it to
“close” and maintain operation of the system. The Low-Pressure Switch monitors the feed water
line pressure from the outlet of the Booster Pump and signals the electronic controller if there
is a low-pressure condition in the feed line prior to or at the Booster Pump. When the line pressure
at the Booster Pump inlet experiences an abnormal vacuum, or the Booster Pump is unable to
develop an outlet pressure of more than 40 PSI into the prefiltration components, the
“High-/Low-Pressure“ lamp illuminates and intermittently, blinks. If the condition does not correct
itself or is not corrected by the operator, the system automatically shuts down after 20 seconds
and the “High-/Low-Pressure” lamp steadily illuminates. Refer to the Troubleshooting Chapter
of this manual.
b) High-Pressure Fault
The High-Pressure Switch stops the system if the pressure at the Booster Pump outlet exceeds
190 PSI. This protects the prefiltration components from excessive pressure. The High-Pressure
Switch is a normally closed switch and will open to immediately shut the system off at 190 PSI.
Refer to the Troubleshooting Chapter of this manual.
16. If there are no unforeseen abnormalities, the Seafari Escape System pressure will automatically
increase to normal operating range immediately after starting. The ETD will increase pressure to
a point at which the system produces the specified amount of product water. The next section
(Production, Operating Pressure and Operating Power Consumption) lists approximate expected
