The Craft Brew 500 Reverse Osmosis water system is ideal for small commercial applications
requiring a consistent supply of high-quality water in a simple and compact package. Designed to
be a modular system using mostly common nonproprietary components which allows for cost
effective maintenance and the highest degree of reliability. The 500 can produce up to 500 gallons
of high-quality reverse osmosis water per day. Available with float switch control or stacked with
pressure tank.
Filtration Process
Mechanical Filtration- The USA made sediment prefilter reduces dirt, silt, rust and other sediment
in the water. It’s 5 µm nominal rating helps to give a maximum life to the carbon filtration step.
Activated Carbon w/Polyphosphate- Carbon reduces chlorine and the Polyphosphate reduces
scaling of the membranes.
Reverse Osmosis Membranes- The 500 GPD reverse osmosis membrane is designed to reduce the
dissolved mineral content of the water. In the Reverse Osmosis process, dissolved minerals are
separated from the incoming water to produce the product water (permeate). The excess
minerals are rinsed to the drain. The reverse osmosis membranes have a typical rejection of >
90%. The water is then stored in either an atmospheric tank or a pressurized storage tank for
future use.
Post Filtration- The most common post filter is a carbon block and it is designed to give the water
and enhance polished taste.
Ultraviolet Sanitization- The water passes through an ultraviolet chamber which reduces the
potential of bacteria, viruses and other microorganisms from contaminating the high quality
water.
Dual Digital TDS Meter- The Craft Brew 500 comes installed with a Dual Digital TDS Meter. This
allows you to monitor incoming feedwater and permeate product water.
Blending Valve- The Blending Valve allows you to brew with straight reverse osmosis water or
you can blend minerals back into your product water.

Installation
The Craft Brew 500 is designed for an easy installation. It can be wall hung or it can be installed on
the floor. The system has three John Guest push in connections and a float assembly for a
atmospheric tank.
1. Feedwater is connected to the first bulkhead on the right side labeled INLET. Use the red
3/8 tubing and the 3/8 ball valve included with the system. Connect one end to the unit
the other end to your feed water.
2. Install the float assembly into your atmospheric tank. The float has a 3/8 John guest
tubing fitting on the end.
3. The middle bulkhead labeled TANK, use the yellow 3/8 tubing and connect one end to the
middle bulkhead of the unit and the other to the float assembly.
4. The last bulkhead to be connected labeled DRAIN use the black 3/8 tubing and run that to
a sink or floor drain. Included is a saddle clamp to run to sink.
If wall hanging, the wall holes are set to the 16 inch center for easy hanging.
Included in the manual are a couple of drawings for installation.
Startup
After all connections have been made and unit is secure open your feed valve and flood the filters
with water. The system is now ready to be plugged in. The system is pressure switched controlled
and will start filling your tank immediately. Look inside the tank to make sure the tank is filling
properly. Lift float up and wait for unit to shut down. This should take one to two minutes. Make
sure your blending valve is off. After the system is running press the power button on the TDS
meter. You should see digital numbers representing TDS of the water, press the number two
button on the meter to see your product water quality. Make sure your blending valve is off.
TDS Meter and Blending Valve
The blending valve is designed to allow feedwater after the carbon filtration into your product
water. All product water blended or not will run through the ultraviolet. With your TDS meter on
and the number two button selected slowly open the blending valve. You will see the number rise
on the TDS meter. This gives the Brewer control over the quality of water they require for
brewing. You have the option to brew with straight RO or blended.

Pre-Filtration Maintenance
1. Pre-filter’s (Sediment and Carbon) should be change approximately every three months.
More often in high demand use. Sediment filter removes dirt, sand, and other debris
down to a 5 µm range. Regardless of how many gallons or a how the filter looks, regular
replacement is important in order to keep the system sanitary. The high-capacity carbon
block with polyphosphate core reduces chlorine and other chemicals and adds a scale
inhibitor to the water in order to extend the life and performance of the reverse osmosis
membrane. The carbon block has an estimated capacity of 20,000 gallons or three
months, whichever comes first.

3. To change the filters unplug the power and turn off the water supply to the system.
Depressurize the filters, do this with the water shut off. Plug in the unit for three seconds.
Use the supplied filter wrench and remove the filter housings from the unit. Remove and
dispose of the use pre-filter’s. Use proper sanitary procedures for replacing the new
filters. Do not touch the filters at any time. It is recommended that the filter housings be
sanitized with 50 ppm chlorine solution during the filter change out procedure and that
the O-ring be removed and cleaned and lubricated with an appropriate silicone O-ring
lubricant. Install the new filters and use the wrench to gently tighten the filter housings.
DO NOT OVERTIGHTEN the filter housings and do not use a petroleum-based lubricant on
the O-rings or lip seal.
Reverse Osmosis Membrane Maintenance
The reverse osmosis membrane should be changed no less than annually. If the water quality or
production rate falls below acceptable tolerances, the membrane should be replaced. It is
recommended that the membrane housing be sanitized with 50 ppm chlorine solution during the
filter change procedure and that the O-ring to be removed cleaned and lubricated with the
appropriate silicone O-ring lubricant. Lubricate the membrane O-ring and lip seal with silicone O-
ring lubricant. Install the new membranes and gently tighten the filter housing caps. DO NOT
OVERTIGHTEN the filter housing and do not use a petroleum-based lubricant on the O-rings or lip
seal.

Ultraviolet Maintenance
The Bulb on the ultraviolet should be changed annually to ensure proper sanitization.

Daily Maintenance:
The system should be left powered on at all times and the system must be installed in a location
that is not subject to water damage. Regular maintenance will lessen the potential for system and
component failures.
1. Check the system for leaks, unusual noises, excessive heat, or any other anomalies
2. Check the water quality daily
Weekly Maintenance:
Carefully and closely inspect the entire system. Confirm that there are no drips or leaks on any of
the system tubing connections.
Three Months Maintenance:
Replace the pre-filters and post filter
https://www.craftbrewwater.com/products/20-x-2-5-3-pack-filter-set
Annual Maintenance:
1. Replace the UV lamp and clean the quartz sleeve
2. Replace the membranes
3. Carefully remove TDS meter probes and soak for two minutes and 10% HCl solution. Rinse
and reinstall
