Draining Component Water (For Winterizing); Cleaning The Ro Membrane - Sea Recovery Aqua Matic XL Compact Modular Series Owner's Manual

4. Configure the System for a Recirculating Closed-Loop configuration as described in the topic
Configuration on page 52.
5. Start the System in MANUAL MODE.
6. Operate the System in the Recirculating Closed-Loop configuration for 10 minutes. After 10 minutes, STOP
the System.

Draining Component Water (for Winterizing)

If the System is, or will be, exposed to freezing temperatures, then components within the System's Post-Filtration
section must be drained of all Product Water.
1. Drain the Charcoal Filter and replace the element.
a) Remove the Charcoal Filter bowl.
b) Remove the water from the bowl.
c) Replace the Charcoal Filter Element with a new Charcoal Filter Element.
d) Place the bowl back onto the lid.
2. Drain the pH Neutralizing Filter.
a) Remove the pH Neutralizing bowl.
b) Remove the water from the bowl.
c) Place the bowl and pH element back onto the lid.
3. Drain the UV Sterilizer.
a) Disconnect the Product Water Line from the UV Sterilizer Filter.
b) Drain the Product Water.
c) Turn the System's power OFF.
d) Lock and Tag the Power Breaker to ensure that the System isn't turned back ON (which will displace the
Winterizing Mixture with Feed or Fresh Water).
e) Discard the Storage Chemical in an environmentally safe manner.

Cleaning the RO Membrane

Throughout its life cycle, the RO Membrane Element requires cleaning; the frequency of which depends on the
amount of production and salt-rejection loss (from normal, day-to-day use). At the element's end of life (EOL),
biological growth and salt accumulation make replacement necessary. To properly assess the RO Membrane
Element's performance changes, Sea Recovery Corporation strongly recommends that you maintain a daily log
of readings for comparison. When making performance comparisons, you must consider, and compensate for, the
following variables:
• Feed Water Temp
• Feed Water Salinity
• System Operating Pressure
After compensating for the preceding variables, a 10% decline in productivity (measured in GPH Flow), and/or a
10% increase in salt passage, indicate that the RO Membrane Element may need to be cleaned.
Important: If a dramatic drop in productivity is observed after the System has been in storage, it may indicate
that the RO Membrane Element has dried out and/or fouling has occurred. In this case, attempt to operate
the system for 48 (or more) continuous hours to saturate the RO Membrane Element's Product Water Channel.
If a dramatic drop in productivity is observed on a day-to-day basis, it may indicate non-cleanable fouling
(e.g. suspended solids from silt, coral dust, iron (rust), river or inland waterway debris, other small solid matter,
etc.). Sewage chemicals and petroleum products will cause irreparable damage to the RO Membrane Element.
