INSTALLATION

VMT- v. JUNE 2008
The product water hose line must go into the top of the product tank to prevent any possible back flow
when the watermaker is off. Teeing into the tank fill or tank vent line (if it is large enough to allow air out
while filling) is sometimes possible.
NOTE:
Village Marine Tec. recommends running the sample line to a galley sink and installing a
dedicated water spigot, free flowing, always open (i.e. a ‘cane shaped’ fixture as used in a
manual galley pump). This allows easy sampling at a sink, a drain overboard and the capability
to fill extra water bottles, while your Little Wonder produces water for all purposes.
FRESHWATER FLUSH
Tap into your boat’s freshwater pressure system (Tee into the cold pressurized side) with a ½” diameter
hose to the carbon flush filter. If the freshwater pressure on board is above 35 psi, install a pressure
regulator.

TO CONNECT THE ELECTRICAL
TURN OFF ALL ELECTRICAL POWER FOR USE WITH THE RO UNIT PRIOR TO CONNECTING TO
THE RO POWER SOURCE. FAILURE TO DO SO MAY RESULT IN SERIOUS INJURY OR DEATH
TO PERSONS HANDLING THE UNIT.
NOTE
:
Adhere to all electrical codes and regulations governing the installation and wiring of electrical
equipment. Typical codes specify the type and size of conduit, wire diameter, and class or wire
insulation depending upon the amperage and environment.
NOTE:
The power supply should always be of greater service rating than the requirements of the RO
unit. This will assure proper voltage even if power supply voltage is slightly less than required.
Never connect the RO unit to a line that services another electrical device. THE RO UNIT
SHOULD HAVE ITS OWN INDEPENDENT POWER SUPPLY
.
Step 1:
Verify all power switches and power sources are in the
OFF
position.
Step 2
Connect power source wire (Po) to line side on RO unit’s breaker.
Step 3:
AC POWERED 110V/220V Little Wonder FRAME:
Connection will be from the separate control box to the vessel’s circuit breaker panel. VMT
recommends use of a 15 amp fuse or circuit breaker.
DC POWERED 12V/24V Little Wonder FRAME:
12 Volt DC units require 6 gauge wire. VMT recommends use of a 25 amp fuse or circuit breaker for the
12 VDC
FRAME
unit. Connect RO unit’s power supply wire (Po) from load side of unit’s breaker,
to power input on the
Little Wonder FRAME’s
terminal strip (Refer to Figure 2.7).
Step 4:
Connect a negative wire from the ground bus bar behind main breaker panel to negative power source
input on unit.
Step 5:
To connect the boost pump, connect positive red wire to switch (+) boost pump terminal and negative
black to negative power source terminal.
