Page 4: Introduction
Introduction Welcome to Spectra Watermakers, your trusted solution for water purification needs. Introducing the Spectra LB-1800/2800/4000, equipped with the revolutionary Spectra Pearson Pump. This cutting-edge high-pressure pump, featuring integrated energy recovery, empowers users to purify up to 75 gallons of seawater per hour (120 gph for the LB-2800) on as little as 750 watts of power. -

Valve and Gauge Panel Connections Limit Switches The Normally Closed terminals on the membrane pressure switch are connected to the controls and will stop the system if it exceeds 850 psi. The Feed Pressure limit switch is also wired to the Normally Open terminals and will close when the feed pressure exceeds 10psi. - Page 6 Valve and Gauge Panel Connections - Back of Panel Filter Condition — Inlet Filter Condition — Outlet Boost Pressure Vacuum Switch Product Inlet Filter Condition Gauge Seawater Inlet Fresh Water Flush Inlet Feed Water Outlet High Pressure Limit Switch Product Water Outlet Membrane Pressure Connection...

Page 7: Component Description
Component Descriptions The Spectra LB-1800/2800/4000 watermaker is designed to be installed in a building or pump house so the system is not exposed to the elements. Feed water must be supplied to the unit at 6gpm (22 lpm) at a minimum of 10psi (0.7bar) and a maximum of 20psi (3.5 Bar). A media filter, which must be sourced independently by the consumer, can be used to reduce the consumption of the cartridge filters. - Page 8 Component Descriptions - Cont. The Valve and Gauge Panel has the analog gauges and valves mounted used to monitor and operate the system. There is a flow meter for the feed and one for the product water. One three-way valve controls the feed water source to switch between running and flush water.
- Page 9 Component Descriptions - Cont. The Valve and Gauge Panel has a series of analog gauges and valves mounted for easy reference to system operation. There are two flow meters, one to measure the inlet flow from the feed pump and the other to measure the product water flow rate.

LB 1800-4000M Plumbing Schematic Note: The inlet and discharge service valves should be installed so the service hoses (when installed) can both be place inside the same bucket. To clean or pickle the system chemicals will be recirculated through the system and must be done with no air in the circulation loop. - Page 13 LB 1800-4000M Plumbing Schematic Cont.

Brine Service Valve Restrictor –Assembled at Factory The system is more tolerant to changed in feed pressure and knocking is reduced if there is a restrictor in the brine discharge line. This restriction creates 3-5 psi of back pressure in the discharge which will increase that range of acceptable feed pressure.
- Page 16 Plumbing Connections - Cont. Product Water Outlet Connect the 1/2” black tubing to the product water outlet fitting on the membrane end cap. Lead the 1/2” hose to the bottom fitting of the product flow meter on the Control Panel. Connect the product flow meter outlet fitting at the top of the flow meter to the common port (bottom of the T) of the supplied 3-way sampling valve, one port should be plumbed to a sampling tap, and the other should be plumbed to the potable water storage tank.

Electrical Connections Systems Pressure Switch cable Mount the Electrical Control Box within 6 feet (2meters) of the motor for the Spectra Pearson Pump. Mount vertically and in a dry location, preferably above the pump assembly to ensure proper ventilation across the heat-sink and so that no water will accidentally spill on the switches or speed control knob. -

Page 23: Initial Startup (Purging Storage Solution)
Initial Startup (Purging Storage Solution) Note: The crankcase in this unit shipped from the factory with oil in the crankcase and tape over the crankcase vent. Confirm that the crankcase is roughly half-full of oil before starting the watermaker (there is a sight glass on back of the crankcase). When starting the machine for the first time ensure the product water is going to a drain until it becomes potable. -
Page 24: Normal Operation
Normal Operation Note If the system contains preservative or antifreeze, or if the condition of the membrane is unknown, follow the “Initial Startup” (purging) instructions on the previous page. When in doubt, Purge the system before running at pressure. Starting: Set the product sampling valve (if used) to send the product to a drain. Turn the feed valve to the ‘RUN’... -
Page 25: Fresh Water Flushing - Dc
Fresh Water Flushing - System It is always a good idea to flush the watermaker after each production cycle. If the system is not used to make water the flush process should be repeated once every 3-5 days, depending on climate (shorter cycle in warm climates) to prevent bacteria growth. Turn off the feed water supply pump and close the Feed valve (OFF). -

Page 27: Maintenance
Maintenance General In installations where the unit is running 24/7 it is prudent to perform a weekly visual inspection. Pressures and flow rates should be recorded in the log for reference. Repair any leaks as soon as possible. Periodically inspect the entire system for leaks and any chafing on the tubing and hoses. - Page 28 Maintenance - Cont. GEARCASE LUBE OIL Use only 5W-30 synthetic oil in Spectra-Pearson Pump crankcase. Do not overfill the crankcase with oil. Check oil condition and level frequently. The oil should be changed every 5000 hours or annually, whichever comes first. The Pearson Pump comes mounted on a counterclockwise rotating CAT crankcase.

Page 29: Long Term Storage
If there is danger of freezing Propylene Glycol potable water antifreeze should be used instead of Spectra Watermakers SC-1. The Pressure Relief Knob on the Spectra Pearson Pump must be open one full turn while circulating preservatives or cleaning compounds!

Page 32: Membranes/Membrane Cleaning
The acid cleaner should be used first. If the membrane fails to respond to both cleanings, this is an indication of another problem with the system, or that it is time to replace the membrane. Contact Spectra Watermakers before removing a membrane. Membrane Cleaning Warning! The pressure relief valve on the Spectra Pearson Pump must be open for this procedure or membrane damage may result. -
Page 33: Cleaning Procedure
You will need 5 gal (20 L) of chlorine free water and the system must have already been thoroughly flushed. 1 lb. (.5 kg) of Spectra Watermakers cleaning chemical into the water and stir It will dissolve in about an hour. Some of the chemical may not dissolve completely, this is normal. -

Page 35: Specifications
Specifications Power consumption will vary with changes in feed water flow rate, salinity and temperature. On standard seawater the 1800 will draw ≈800 watts and the 2800 will draw ≈1200 watts. The boost pump for the feed will typically draw 150 to 300 watts depending on the lift and distance required for pipe runs. -
