Membrane Element Handling and System Storage Warnings
Freezing Temperatures
Caution: The System must be protected from freezing if it will be exposed to temperatures below 32°F (0°C).
Freezing temperatures will cause extensive damage to the System as the water expands during the freezing
process. Resulting damage to the System caused by freezing temperatures is the liability of the Operator.
Caution: DO NOT subject the System to temperatures below 32°F (0°C), unless the System has been rinsed
with a solution of Product Water with 20% food-grade Glycerin (Propylene-Glycol).
RO Membrane Element Handling
Caution: Never store the RO Membrane Element or Membrane/Vessel Assembly in direct sunlight. Never
expose the RO Membrane Element or Membrane/Vessel Assembly to storage temperatures above 120ºF
(50ºC) or below 32ºF (0ºC). High temperatures may cause irreversible damage and up to 40% production
loss in the RO Membrane Element. Freezing temperatures cause mechanical System damage, as well as
irreversible damage to the RO Membrane Element.
Caution: The RO Membrane Element must remain wet at all times. Never allow the RO Membrane Element
to dry out, as drying out may cause up to 40% production loss, as well as irreversible damage. Some, but
not all, production may be restored by saturating the RO Membrane Element in Product Water for several
days, and then operating the System by feeding Product Water into the System for a continuous 48-hour
period.
Caution: Never expose the RO Membrane Element to chemicals other than those supplied by Horizon
Reverse Osmosis. Use caution when operating the system in harbors that may be polluted with chemicals,
oil or fuel, as these chemicals may damage the RO Membrane Element beyond repair.
Caution: Protect the RO Membrane Element from biological fouling, as it may cause significant production
loss. Some, but not all, production may be restored after cleaning. The System must be protected from
biological fouling if it will not be operated over a period of two (2) weeks or more.
Important: Third-party chemicals will destroy the RO Membrane Element! Only use Horizon Reverse
Osmosis-supplied chemicals. Never use third-party chemicals, as they are incompatible with various System
materials and will dissolve the co-polymer parts. Damage to the System or its components as a result of
using third-party chemicals is not covered by the Horizon Reverse Osmosis Corporation Warranty.
Fresh Water Flush
There must be sufficient Fresh Water in the Potable Water Storage Tank. In order to provide the required water
flow to the System during the Fresh Water Flush cycle, the ship's fresh-water pressure system must deliver a
