CONGRATULATIONS
Your Spot Zero™ reverse osmosis system is a durable piece of equipment, which, with
proper care, will last for many years. This User’s Manual outlines installation, operation,
maintenance and troubleshooting details vital to the sustained performance of your system.
Your system is designed to operate at a pressure of 80-150 psi, unless otherwise stated.
The recovery set for your system is between 50%-75%.
NOTE: Prior to operating or servicing the Spot Zero reverse osmosis system, this User’s
Manual must be read and fully understood. Keep it and other associated information for
future reference and for new operators or qualified personnel near the system.
SYSTEM REQUIREMENTS AND OPERATION GUIDELINES
PLUMBING
The membranes and high-pressure pumps used on Spot Zero systems require a continuous
and nonturbulent flow of water to the system with a minimum feed pressure of 20 psi during
operation, which does not exceed 105°F.
The tubing or piping used for the inlet of the feed water is 3/4" ID. The tubing or piping used
for the discharge of the concentrate is 1/2" O.D. and should be run to an open overboard
free and unrestricted
The tubing or piping used for the product is 3/8” O.D. and can be transported to the holding
tank or directly through a high-quality nylon tubing or PVC pipe or other FDA accepted
materials.
Material must not precipitate in the system. Be certain that all the components of the feed
water are soluble at the concentrations attained in the system.
CAUTION: Any restrictions or blockage in the overboard discharge line can cause back
pressure, which will increase the system’s operating pressure. This can result in damage to
the system’s components and possible leaks of components or tubing.
ELECTRICAL
The motors used on Spot Zero™ systems are pump and motor combinations. They are
available in single- phase 115 volt or 230-volt AC.
Please ensure that the electrical circuit supplying the system is compatible with the
requirements of the specific Spot Zero™ model.
4

PRE-FILTRATION
Spot Zero™ systems are supplied with a 1-micron sediment pre-filter (part # 252404005) that
filters out most particles over 1-micron, a GAC/KDF (part # 252404004) Cartridge that removes
chlorine, chloramine, VOCs and heavy metals. CAUTION: a traditional carbon block filter must
not be used as it will not remove chloramines and will cause permanent membrane damage.
Pre-Filters should be changed every 100 hours and/or whenever there is a pressure difference
of 15 psi or more between the pressure readings before and after the filter. The pump must
NEVER be run dry. Operating the pump without sufficient feed water will damage the pump.
ALWAYS feed the pump with filtered water. The pump is susceptible to damage from sediment
and debris.
NOTE: THE SZ10KDF2 CARTRIDGE MUST BE FLUSHED OUTSIDE OF SYSTEM BEFORE
OPERATING TO REMOVE CARBON DUST.
You can head to www.spotzero.com/support to see demo videos. Do not attempt to clean used
filter cartridges. The SZ10KDF2 is rated to absorb chlorine, chloramine, heavy metals, etc. up to
18,000 gallons of feed water, which is the equivalent to approximately 100 hours of runtime.
CAUTION: If the pre-filter becomes clogged and the water flow to the pump is
reduced or interrupted, cavitation will occur. This will damage the pump.

PRINCIPLES OF REVERSE OSMOSIS
HOW FRESH WATER IS PRODUCED
Reverse Osmosis or “RO” is a process where freshwater water is produced by pumping
saltwater through a semi-permeable membrane.
OSMOSIS
Osmosis is a naturally occurring process where a weak solution will cross a semi-permeable
membrane to mix with a highly concentrated solution. For example, a freshwater solution will
naturally want to mix with a saltwater solution.
REVERSE OSMOSIS
To reverse this process work is put into the system using a pump. The pump causes pressure
to build up on the saltwater side of the membrane. This pressure forces water across the semi-
permeable membrane. The membrane is designed to allow the water molecules to pass while
preventing the salt and other solids from doing so. Fresh water is collected on the other side
of the membrane as a result.

3. From the pre-filter outlet fitting, run the white nylon 1/2” Spot Zero water tubing to the
feed from pre-filtration fitting.
4. From the “Overboard” discharge fitting, run the white nylon 1/2” Spot Zero water tubing
to a dedicated overboard fitting. Water must be allowed to run freely, without any
restrictions or blockage in the brine discharge line. Be sure that no back pressure exists
in the “Overboard” discharge line.
Note: There is an internal check valve in the brine discharge line in the system.

STORAGE
STORAGE OR WINTERIZATION OF UNIT
If the vessel will not be able to allow for fresh water flushing over the duration of the storage
period, themembrane vesselsmust have static water replaced with membrane storage chemical
solution. Membrane storage chemical part # is 252404263.
WINTERIZATION
Option 1: Winterization with membrane rack removal - The best practice for winterization is
to remove membrane rack and store with membrane storage chemical inheatedstorageclimate.
The remainderofthe system should be stored with propylene glycol from sea cock to overboard
to prevent freeze damage (propylene glycol can be purchased at most hardware or automotive
retailers).
Option 2: Winterization without membrane rack removal - If the system is going to be
exposed to freezing or near freezing temperature while being stored and the membrane rack
cannot be removed and stored in a heated climate, the following should be done. A 50% solution
of storage chemical and 50% propylene glycol should be run through the entire system from sea
cock to overboard andthen valveoff both seacock and overboard. Membrane storage chemical
part # is 252404263.
NOTE: PROPYLENE GLYCOL CAN BE PURCHASED AT MOST HARDWARE OR
AUTOMOTIVE RETAILERS
WARNING:DO NOT USE ETHYLENE GLYCOL, ONLY NON-TOXIC
PROPYLENE GLYCOL SHOULD BE USED.
RE-COMMISSIONING OF SYSTEM AFTER STORAGE OR WINTERIZATION
After storage or winterization, the system must be completely voided of all storage chemical and
or propylene glycol. To do this, follow the new system startup guide on page 33.
