Installation Instructions
Residential Reverse Osmosis
Drinking Water System
PuROMax Reverse Osmosis System has been tested to ensure it will operate correctly. The following periodic
maintenance is recommended so your system will provide years of trouble-free service:
Replacement parts Replacement
PuROMax SF5-10 Pre-filters (sediment) every 6 mos.
PuROMax PCTO/2 Pre-filter (activated carbon) every 6 mos.
PuROMax R/O membrane every 2-3 years
PuROMax Aicro Post filter (carbon) Every 6 mos.
Components
The following components make up your PuROMax Reverse Osmosis Drinking Water System:
PuROMax SF5-10 Pre-filter
(sediment) removes larger particles such as sand, silt, rust and scale.
PuROMax PCTO/2 Pre-filter
(activated carbon) removes chlorine in the feed water to protect the reverse osmosis
membrane.
Reverse Osmosis Membrane
reduces
dissolved
minerals, metals and salts. During the process harmful compounds are
separated by the membrane and the reject water goes to waste (drain).
An activated carbon
post-filter
is provided for a final “polish” and to remove foul tastes, odors and to
provide great tasting drinking water.
Filter housings
and
R/O module
hold pre-filters and membranes. A
bracket
is provided so they may be mounted,
typically below sink.
Storage tank
holds filtered water, ready for use.
Automatic shut-off valve
senses when the storage tank is full and closes the water supply to conserve water.
The dedicated
faucet
is used to dispense RO produced water when needed.
Feed water saddle valve
is connected to the cold water line to supply water to the R/O system.
Waste water saddle valve
is connected to the drain to remove reject water from the R/O system.
Tubing
supplies feed and reject water.
Fittings
are used for necessary hose connections.
Tools
The following tools may be necessary, depending on each particular installation:
3/8” variable speed electric drill; 1/8” &1/2” bits
1-
1/4” porcelain whole cutter (if hole for second faucet is not provided).
Center punch and hammer
1-
1/4” wood bit
Concrete drill bits
Phillips head and flat blade screwdrivers
Adjustable wrench
Crescent wrench
Teflon tape
Plastic tube cutter
Air pressure gauge (low pressure)
Air pump (hand)
System location
Your PuROMax R/O system may be installed under a sink, in a basement or other location, depending on available
space. Do not install unit where temperatures fall below freezing. Do not install the drain saddle valve near a garbage
disposal; otherwise, plugging of the waste water line may occur. If discharging into a utility sink or standpipe, an air gap
must be provided. (Air gaps must be 1” or greater above the floor rim.)
Note: Plumbing codes may require the use air gaps. Please check with your local municipality.
Do not connect the R/O system drain line to the dishwasher drain line due to the fact back pressures may cause the air
gap to overflow.
