2.2 Safety Information
Read the instructions before operating and keep them
nearby. Be sure to follow all directions in the manual.
Do not open unit or fuel cartridges. Do not use force to
open cartridges and do not refill them. Any
modifications to the unit may affect safe operation,
will lead to a loss of license and will void the warranty
Use only original EFOY equipment.
Do not store unit and fuel cartridges at temperatures
above 45° C. Do not operate at temperatures above
40° C. Keep away from heat and direct sunlight.
Store the unit where there is no danger of freezing, or
use the automatic antifreeze feature.
Do not smoke when handling the unit or the fuel
cartridges.
Keep away from heat and open flame.
There is a danger of fire if methanol leaks out
following an accident, or if the unit or the fuel
cartridge has been damaged. Keep away from open
fire and make sure area is well ventilated. Small
amounts of methanol which may leak out will
evaporate without leaving any residue.
Keep unit and fuel cartridges (including empty or
partially filled cartridges) out of children’s reach.
Operate the unit only in accordance with instructions
and keep operating area well ventilated. Do not block
exhaust. Avoid inhaling exhaust fumes directly or for
prolonged periods of time.

2. Introduction

There is no risk of coming into contact with methanol
provided that you handle the unit and fuel cartridges in
accordance with instructions.
We are required by law to print the following notice.
Methanol is toxic if inhaled, ingested or if it comes into
contact with skin. Irreparable damage may occur if
inhaled, ingested or if it comes into contact with skin. In
the event of an accident or if nausea occurs, consult a
physician immediately. Be sure to bring the fuel
cartridge label or these instructions to the consultation.
System exhaust may contain harmful components. Avoid
inhaling exhaust directly or for prolonged periods of
time. Use the exhaust hose to conduct exhaust gases to
the exterior.
Improper use or improper connection to other electrical
devices may result in damage.
WARNING
In addition to these safety instructions, please observe
the passages in bold type. Otherwise, you may
endanger yourself and others.

Methanol is easily flammable. Methanol is toxic if
inhaled, ingested or if it comes into contact with skin.
In the event of an accident or if nausea occurs, consult
a physician immediately. Be sure to bring the fuel
cartridge label or the methanol material safety data
sheet to the consultation.
Storage and transport of methanol may be subject to
statutory regulations.
More information is provided in the methanol safety
data sheet on our website www.efoy.com or by SFC

WARNING
Securely fasten unit and fuel cartridges when using on
board motor vehicles.
Do not operate unit if there is danger of explosion.
Unit is not watertight. Make sure that no water can
enter.
Keep unit and fuel cartridges away from children,
temperatures in excess of 45° C and direct sunlight.
4.1 Tools and Materials
You will need the following tools and sealants to install
the fuel cell:
electric drill
jigsaw
screwdriver
hexagonal (Allen) wrench
sealant such as Sikaflex
Use the following screws, depending on the mounting
surface (screws are not included):
8 screws to attach the mounting plate
4 screws to attach the remote control
4 screws to attach the fuel-cartridge holder
cable clamps and fixing screws, if needed

4. Installation

4.2 Space Requirements
Installation should be carried out by trained personnel
only. Wear proper work clothes. Avoid flowing
garments and wear a hair net if you have long hair.
Clothing and hair can get caught in moving or rotating
parts such as in a drill.
Be sure to leave enough space behind the installation
area when drilling or cutting out openings. Also be sure
to follow the tool manufacturer’s safety instructions.
Solvents used in sealants may emit fumes. Make sure
that there is sufficient ventilation and follow the
instructions for the sealing compound.
Make sure when choosing a location, that the
temperature ranges between –20° C and +40° C.
WARNING
This unit generates heat, thus requiring ventilation.
Please take this into account when considering
possible locations.

Make sure that the fuel cartridge is located within
reach of the connecting hose (30 cm) and that the hose
is neither kinked nor crushed.
The fuel-cartridge hose and the exhaust hose may not
be damaged. Do not substitute another hose for either
of the two.
Use only original-equipment EFOY hoses.
4.3 Securing the unit
Select a suitable location as described in Chapter 4.2,
paying attention to the dimensions in Chapter 3.4.
1. Run the belt in the groove under the mounting plate.
2. Secure the mounting plate tightly to the desired
location. Use eight proper screws and dowels, if
necessary, so that the mounting plate cannot shake
loose in case of an accident.
3. Place the unit onto the mounting plate.
4. Strap the unit tightly to the mounting plate.

Use the bow to conduct warm air to the side.
If you do not need the off-heat bow, you can disconnect it
from the off-heat flange and connect the off-heat tube
directly to the flange.
Make sure that the off-heat tube is not kinked; use a
second bow if needed.
Sink the screws for the off-heat flange into the holes
provided.
Then pass the off-heat tube to the exterior. You will
need an opening with a 100 mm diameter.
Be careful of electrical lines when drilling. Your dealer
can provide information as to the location of lines.

Pass the off-heat tube through the opening; any excess
may be shortened.
It may be necessary to use an external face plate to
protect the outlet. Use a suitable sealant to prevent
moisture from penetrating into the body or into the
interior.
4.5 Connecting the Exhaust Hose
Within the fuel cell methanol and oxygen are converted
into water and carbon dioxide. This chemical reaction
generates off-heat which needs to be conducted
together with water vapour and carbon dioxide to the
outside.
WARNING
Connect the enclosed exhaust hose and always
evacuate the exhaust gases from the installation
compartment or site to outdoors.
Exhaust gasses contain moisture and may exceed
60° C, causing scalding. Exhaust byproducts may
contain injurious substances. Avoid inhaling exhaust
directly or for long periods of time.
To prevent freezing in winter, the exhaust hose may
not too long and should be cut diagonally to avoid the
emergence of drops.
At no time may siphoning occur in the hose. Make sure
that the hose is neither clogged nor blocked.

Routing the exhaust hose
Up Down Avoid siphoning

Remove the cap from the exhaust port. Retain the
cap for winter storage or for possible returns.
Attach the exhaust hose (included) to the exhaust
port.
Take the exhaust hose out of the installation
space and seal the opening for the exhaust hose
with suitable sealing material. The exhaust
(which also includes condensate) can be directed
outside, to a wastewater tank or other suitable
container (on yachts also in the bilge). But make
sure that there is a hose that allows the gasses
including the carbon dioxide to evaporate.
The exhaust hose should be as short as possible.
The part of the hose at the outside should not be
longer than 5 cm. Cut diagonally the end of the
hose to avoid the emergence of drops.
The exhaust hose can be shortened as required.
The opening must have a diameter of 10 mm.
Make sure the exhaust hose has no kinks or
blockage and that exhaust can escape freely.
