Installation & Operating Manual
G500

2
Congratulations on your purchase of the G500™ Direct Flow Reverse Osmosis System.
The G500 Direct Flow Reverse Osmosis System is designed with advanced filtration technology, and utilizes a
5-stage filtration process to purify and deliver fresh tasting water. This system is designed exclusively for municipal
water systems, and will remove volatile organic chemicals, chlorine, odor, sediment, suspended impurities, metals
and other harmful contaminants from your water.
This instruction manual illustrates the G500 Direct Flow Reverse Osmosis System installation and operation. Please
read the contents of this manual before installation.
The system should be installed by a qualified professional installer or licensed plumber. Installation must be in
accordance with local and state plumbing codes.
INTRODUCTION AND WARNINGS
G500 Compact Reverse Osmosis System
INTRODUCTION
PRECAUTIONS BEFORE INSTALLATION
• WARNING: Do not use with water that is microbiologically unsafe or of unknown quality without adequate
disinfection before or after the system.
• WARNING: The system may at no point be exposed to pressures above the rated pressure as this may cause
system damage!
• WARNING: A qualified installer shall install protective devices if the system pressure may at any time exceed the
rated maximum pressure due to pressure surges or water hammer, or other excessive pressure events to ensure
that the maximum operating pressure of the system will not be exceeded!
• CAUTION: Water pressure must not exceed 4 bar | 60 psi. Minimum water pressure should not be lower than
1.4 bar | 20 psi.
• CAUTION: Protect system against freezing. Freezing can cause system damage and result in water leakage!
• CAUTION: Install the system in a sheltered or covered location and protect it from excessive heat!
• CAUTION: Do not install where the system will be exposed to direct sunlight!
• CAUTION: The system is intended for use with tap water, and should not be installed for use with other water
sources, such as mountain spring water or groundwater.
• CAUTION: System must be installed on the cold-water piping line. Do not install on hot water piping. Inlet water
temperature should not exceed 100°F | 38°C.
• CAUTION: Avoid ambient temperatures over 100°F | 38°C
• CAUTION: System contains replaceable sediment and activated carbon filters, as well as a replaceable reverse
osmosis membrane which is critical for the eective reduction of TDS (Total Dissolved Solids). Water purified by
this system should be tested periodically to confirm the system is operating properly.
• CAUTION: Filters must be installed according to labeling and with the designated inlet water flow direction.
• CAUTION: Pay attention to safety when drilling close to the wires and plumbing parts of the installation.

REPLACEMENT FILTERS AND PARTS
• Filters are consumables and are not covered by the warranty.
• Only use GWS approved replacement filters. Product warranty is void if non-GWS approved replacement filters
are used.
• Only use GWS approved spare parts. In the case of any failure of the pump, electric adapter or any other
replaceable part of the system, the replacement product must be approved by Global Water Solutions or an
authorized GWS distributor. Product warranty is void if non-GWS approved spare parts are used.
OTHER IMPORTANT INFORMATION
• Please note that the lifetime of the filters as well as their replacement interval strongly depends on the inlet
water quality, the amount of water consumed, the sediment and chlorine content etc.
• System should be isolated from water supply and disconnected from power if not used for more than 1 week.
If not used for a period of 1 month or more RO water storage tank should be emptied.

FILTER REPLACEMENT PROCEDURE
1. When replacing the filters, first release the water and air inside of the system by closing the water inlet. Open the
faucet and drain out the water inside of the G500 system before opening the housing cover.
Important: For first installation, turn o the water inlet switch or water source. (refer to Fig. 1)
G500 SYSTEM LIGHT INDICATION
AUTO-REL.: A blinking light indicates that the system is performing auto flush.
