Description and Usage:  Inline tankless water heater. Use for space restricted applications such as boats, pool, camp facilities and RV. You can have a fully functional hot water shower system at a fraction of the normal equipment cost and installation time normally required. This system only uses electricity when operated. The units are "on-demand" and "tankless" and therefore only need a single water source to operate. When installed, they provide an instant heating on demand.  Simpler setup than with a water heater. Less to go wrong and easier to install and maintain. Available in 120 volts AC,  5400 watts OR  220 volts AC 5400 watts range  On standard 240 VAC power rating is 6200 watts.  You can also opt for an element that yields 8200 watts on 240 VAC power for an extra 10$. ( requires 33 amps @ 240VAC ....not available for the 120VAC element ) 

Operation: You control temperature by changing the amount of water coming out. Same heat setting with more water means cooler output and vice versa. Great for installing in your cabin ! New in package. Comes with instructions. See full instructions and description at  (cut and paste into browser) 

   Below are the instructions for installation.

Features

Practical and economic. Automatic drive switching turns on heating element with the opening of the water 
valve therefore consuming energy only in this condition. The power is switched  when you turn on the water 
valve  by a pressure sensing unit. The temperature of the water is set by modulating how much water flows 
through the heating element.

INSTALLATION 
The installation sequence in this manual should be carefully followed. 
Verify the voltage of the heater corresponds the voltage of the line you are
installing on. The voltage is printed on the unit.  See Fig  1.

 figure 1

Verifies you have a direct line from the breaker.  See the picture of the power 
distribution circuit  fig. 2. 

Figure 2

 Use adequate wiring and breaker or fuse taking in account the values of voltage
 power and the length of wiring. See table below: 

For distances above 90 feet, you should use bigger conductors. .
Use a bipolar breaker 220 Volts(phase-phase) or single-pole breaker in the 
conducting phase for 127 Volts(phase-neutral). Verify ground in the
power line is making good connection.

The water pressure at the water output must be a minimum of 2 mca. 
This is the pressure of water that corresponds to a height
of a column of water that is 2 meters tall. The maximum pressure allowed is
40 mca. See fig. 3

Safety Notes 
To prevent electric shock, connect the ground wire of the product to an
adequate grounding system.

Do not use the Neutral wire as ground.

The installation of the system must be performed by a qualified professional.

See fig.4.

Plumbing Installation

Open the valve and let it run water sufficiently in order to remove any sediment.
If the water pipe is not 1/2 inch is of 3/4" use an adapter to 1/2" inch. 

For water pressure between 8 mca. and 40 water mca. you should include the reducer
in the water input of the inline water heating unit. If the pressure exceeds 40 mca
you can destroy the unit. 

This unit must be installed vertically as show below in figure 5

Fig 5

The unit can be installed on a single line faucet or with a mixer type
plumbing setup as show in fig 5. 

To mount elbow "B" to the wall separate elbow "B" from elbow "A" by removing
the retaining key. Mount elbow "B" to wall and re-mate elbow A to elbow B 
making sure to replace the O-ring where you found it at dissassembly. Fig. 6
Make sure to use only your hands to mount to the wall to avoid damaging the 
pipe. Use thread tape where appropriate but not in the elbow to elbow junction.

If other piping is available you may leave out elbow B and mount directly to 
elbow A.

The flexible hose is the output port of the inline heater. Use the flexible hose
to make the water connection to the sink assembly. Use the washers to 
make the water seal on the flexible hose assembly as shown in fig 6

Places the on/off switch of the Heater in the off position.
The threading system of the elbows has been designed to allow for versatility of placement
when mounting the heater.


PREFILL THE HEATING CHAMBER

Run water through the Heater before making the electrical connection to fill it with
water. Doing this prevents burnout of the heating element. Verify flow of the water
out of the faucet and after adequate time for filling close the water valve. Here
by water valve it is meant the valve used to operate the sink normally. (Not
the cut off valve.)

ATTENTION: Always repeat this operation when the inline heater is removed for some reason.

ELECTRIC INSTALLATION 

When newly installing the inline heater set the wall wiring box 12 inches above
the water pipe coming out of the wall.  See  fig. 7. 

Disconnect the breaker in the circuit that feeds the inline heater.
Connect the wires of the Heater to wires of the power circuit. See fig. 8.
Connect the heater ground to the grounding system.

Operation

Place the On/Off switch of the Heater in the on position. See Fig 9.
Close the breaker in the electric distribution circuit that the heater
is installed in. Open the water valve (hot water valve) and you should
sense that the warming of the water occurs in the output of the faucet.
You regulate the temperature of the water through the faucet valve.
The unit uses a relatively constant amount of power to heat the water
so more water with same power yields cooler water. Conversely lowering
the water flow rate allows the water longer time to heat as it passes
through the unit and therefore it exits at a higher temperature.
For safety and greater useful life of the components of the heater,
only switch the unit with the water faucet valve closed. This can 
be done easily because there is a pressure sensor that automatically
turns on the unit when you turn the faucet on.

MAINTENANCE 

Do not disassemble the product with the power on. For internal maintenance
disconnect the power breaker that feeds the inline heater.

Use a damp cloth to clean the outside when required. Do not use abrasives as it
will mar the finish.
