Pump output flow of water must all be matched. Upon leaving Horizon Reverse Osmosis’s factory at
the time of shipment, these components have been matched and tested together as a system.
If the initial Horizon Reverse Osmosis customer (distributor, dealer or boat builder) has mistakenly
interchanged one or more of these components from other systems in their stock, this will cause a
mismatch resulting in insufficient operating pressure, insufficient product water flow, excessive operating
pressure or excessive product water flow. If one or more of these components has recently been
replaced, it may have been replaced with the incorrect component.
If the system is new and being operated for the first time or if one or more of the above-mentioned
components has recently been replaced, check to ensure that the three components are properly
matched. Refer to the following two pages.
ETD: If the ETD has been improperly changed to a higher size code from “B-22” to “B-25,” product
water flow will increase along with higher-than-normal operating pressure. The High-Pressure Switch
will eventually signal the system to shut down due to excess pressure at the Prefilter Inlet Pressure
Gauge.
If the ETD has been improperly changed to a lower size code from “B-25” to “B-22,” product water
flow will decrease along with lower-than-normal operating pressure and poor product water quality.
BOOSTER PUMP: If the Booster Pump has been improperly changed to a higher size code (i.e., from
100 GPH to 140 GPH) product water flow will increase along with higher-than-normal operating
pressure. The High-Pressure Switch will eventually signal the system to shut down due to excess
pressure at the Prefilter Inlet Pressure Gauge.
If the Booster Pump has been improperly changed to a lower size code (i.e., from 190 GPH to 125
GPH) product water flow will decrease along with lower-than-normal operating pressure and poor
product water quality.
RO MEMBRANE ELEMENT: If the RO Membrane Element has been improperly changed to a HIGHER
size code from “A” to “B” or “C” or from “B” to “C,” then product water flow will not change and the
operating pressure will decrease resulting in poor product water quality.
If the RO Membrane Element has been improperly changed to a lower size code from “B” to “A” or
from “C” to “B” or “A,” then product water flow will not change but the operating pressure will increase.
The High-Pressure Switch will eventually signal the system to shut down due to excess pressure at
the Prefilter Inlet Pressure Gauge.
Product Water Abnormalities
• Insufficient Product Water Flow
• Excessive Product Water Flow
• Poor Quality Product Water
The production of the system (product water flow) and the quality of the product water (high quality
indicates low salinity; low quality indicates high salinity) are dependent upon the proper amount of
feed water flow and operating pressure at the RO Membrane Element. Product water flow or quality
abnormalities can be the result of pressure abnormalities described on the previous pages, which are
repeated below.
Production abnormalities can also be the result of worn seals, worn O-rings, cracks or damage at
sealing surfaces, or a fouled RO Membrane Element.
Quality abnormalities can also be the result of worn seals, worn O-rings, cracks or damage at sealing
surfaces, or a fouled RO Membrane Element, Feed Water Temperature, and/or feed water salinity.
