Installation Information

Before we get into the installation, let's familiarise ourselves with the components.

HOH Cell (24.5 cm D x 6 cm W) Electrolyte Reservoir (28- 20cm H x 10cm D) Fluid Level Indicator Fluid Return Gas and Fluid Exit Gas Out to Air In-take Auxiliary Port Water Refill and Pop Off Cap

The installation requirements for the HOH Cell and Electrolyte Reservoir are quite straight forward.

The Electrolyte Reservoir needs to be mounted just above the HOH Cell, this allows for gravity circulation between them and maintains a small bulk head of pressure / vacuum between the two devices. This contributes to the outstanding efficiency of HOH Cell and allows the HOH Cell to continue to function normally when either under pressure or vacuum. The Electrolyte Reservoir carries out the functions of a Bubbler, where the gas and fluid is bubbled through the liquid, before being scrubbed to remove excess electrolyte.
The HOH Cell can be mounted in a variety of directions to fit under the hood of your vehicle, horizontal as shown above, or vertical with the cell directly below. The Electrolyte Reservoir's height can be adjusted prior to assembly to reduce the overall height should this be required! See Specifications for details. Should you decide, additional cells can be added in series (double the voltage) or parallel (double the amperage). This is only limited by the safe working energy available from your power source (alternator) Less than 30 AMPs for most passenger vehicles, unless otherwise stated in your vehicles specifications.
The HOH Cell can be mounted lower and further away from the Electrolyte Reservoir than pictured. The lower the HOH cell is mounted beneath reservoir the greater the circulation. Pictured is the minimum mounting distances, where the HOH gas out port is no higher than the entry point in the reservoir. If the HOH Cell can be mounted in a well ventilated area this would be advantageous. The gas entry and exit ports are fully adjustable allowing you to install the cell in the most convenient location. The connection hose to the Fluid in Port should be longer than the gas exit port. The ports can be adjusted by 360 degrees and Teflon tape should be used to ensure a water tight seal. There are a number of ways these ports can be configured, both entry and exit port on the front, entry port on the rear, exit port on the front and vise versa, both entry and exit ports connected to the top back and top front of the cell, the HOH cell can be mounted flat, although keeping the cell on its vertical plain will increase efficiency, DO NOT connect both entry and exit port to the bottom ports of the HOH Cell, as this will empty the cell of water and prevent it's operation. The unused bottom ports on the rear of the HOH Cell can be used for vacuum air in-take, a one way inline check valve is used to prevent fluid from existing the cell, yet allowing air to enter when running under vacuum a tap can be used to regulate the volume of air drawn in to the cell.
Electrical Connection
Electrically the HOH cell is mounted to the chassis of the vehicle, providing the earth connection. With the other sides connection nuts providing the positive 12V connection to the battery. Below is a schematic of the full wiring diagram.
It is important that the cell runs only when the car is running, therefore using the Oil Pressure Switch as the trigger for the relay ensures the engine has started before the cell begins to operate and stops if the engine stops, even if the ignition is still on.
Connecting the Gas to your Engine
There are a number of ways to connect your HOH Cell to your intake of your vehicle.
In this picture you will see that the gas is connected underneath the carburetor, just below the butterfly. It can also be connected as shown below on carbureted vehicles in between the air filter and carby.
In most EFI vehicles, the HOH gas line would be connected between the air filter and manifold inlet.
It is also possible to connected the HOH gas line to the air filter itself.
Maintaining your HOH Cells
Filling your HOH Cell with electrolytic fluid. As indicated by the Number 8 the refill cap is removed and using a funnel Deminalised Water and Sodium Hydroxide, Lye (NaOH) is added. Refill Cap can be located on either side which allows for the cell to be mounted either to the left or right of the reservoir. The concentration of the Sodium Hydroxide can be as high as 25% of water volume. As in most cases Sodium Hydroxide comes in pre-mixed with water in concentration of 48.5%, in this case add 50% Sodium Hydroxide and 50% water for a 25% concentration. If the sodium Hydroxide is in a crystal form, concentration is calculated by 25% weight. (250 grams to 1 Litre of water). It is recommended that a weak concentration is used to begin with, then additional alkaline added to increase to desired amperage (15-20 Amp with the Cell is at operating temperature (40-50 Deg C.) The concentration of the Sodium Hydroxide can be varied to lower or increase the total load put on your alternator. Gas quantity will fall with weaker concentrations and rise with higher levels to a maximum of 25%. Sodium Hydroxide is very corrosive so be sure to follow the safety instructions provided with your HOH Cell and clean any spillage thoroughly with water. WEAR SAFETY GLASSES AND SKIN PROTECTION WHEN EXPERIMENTING!

Even though the installation is quite simple, if you are not mechanically oriented, then simply take your HOH cell and these instructions to your local auto shop. They should be able to install this for you within 2-3 hours.
