Figure 2: Preventing electric shocks
Preventing electric shocks
• Always ground (earth) the machine electrically.
• Use only a source of AC power that complies with
local building and electrical codes, and that has
both overload and ground-fault protection.
• Before connecting the machine to power, check
that the voltage indicated on the machine’s serial
label matches your local AC power voltage. If your
AC power voltage does not match, do not use the
machine. Contact Martin™ Service for assistance.
• Before using the machine, check that all power
distribution equipment and cables are in perfect
condition and rated for the current requirements of
all connected devices.
• If the machine or any cables connected to it are
in any way damaged, defective, wet, or show
signs of overheating, stop using the machine
and contact Martin™ Service for assistance. If
the supply cord is damaged, it must be replaced
by a special cord or assembly available from the
manufacturer or its service agent.
• Disconnect the machine from AC power before
servicing and when not in use as directed.
• This machine is not waterproof and must not
be exposed to wet outdoor conditions. Do not
immerse in water or any other liquid. Do not
expose to high-pressure water jets.
• Do not spill uid over or inside the machine. If
uid is spilled, disconnect AC power and clean
with a damp cloth. If uid is spilled onto electronic
parts, take the machine out of service and contact
Martin™ for advice.
• Do not remove the covers or attempt to repair a
faulty machine. Refer any service not described in
this manual to Martin™ Service.
• Do not operate the machine if any parts are
damaged, defective or missing.
• Moisture and electricity do not mix. Do not aim fog
output at electrical connections or devices.

Preventingburnsandre
• Do not attempt to bypass thermostatic switches,
uid sensors or fuses.
• Replace fuses only with ones of the type and
rating specied in this manual for the machine.
• Provide a minimum free space of 500 mm (20 in.)
around the machine.
• Provide a minimum free space of 500 mm (20 in.)
around fans and air vents and ensure free and
unobstructed air ow to and around the machine.
• Do not operate the machine if the ambient
temperature (Ta) is below 5° C (41° F) or above
40° C (104° F).
Preventing injuries
• Check that all external covers are securely
fastened.
• Do not operate the machine with missing or
damaged covers or shields.
• In the event of an operating problem, stop using
the machine immediately and disconnect it from
power. Do not attempt to use a machine that is
obviously damaged.
• Do not modify the machine in any way not
described in this manual or install other than
genuine Martin™ parts.
• Refer any service operation not described in this
manual to a qualied technician.
• Fog output can cause condensation. Do not point
the output at smooth oors. Floors and surfaces
may become slippery. Check these frequently
and wipe dry as necessary to avoid any danger of
slipping.
• Ensure at least 2 m (6.6 ft.) visibility in areas
where fog is being produced.
• Fog uid contains food-grade glycols in solution
but may present health risks if swallowed. Do not
drink it. Store it securely. If eye contact occurs,
rinse with water. If uid is swallowed, give water
and obtain medical advice.
• This appliance is not intended for use by persons
(including children) with reduced physical sensory
or mental capabilities, or lack of experience
and knowledge, unless they have been given
supervision or instruction concerning use of the
appliance by a person responsible for their safety.
Children should be supervised to ensure that they
do not play with the appliance.

Preventing breathing problems
• A machine can operate safely only with the fog
uid it is designed for. Use the machine only with
uids specied or you may cause the release of
toxic gases, presenting a severe health hazard.
You will also probably damage the machine.
• Do not create dense fog in conned or poorly
ventilated areas.
• Do not expose people with health problems
(including allergic and/or respiratory conditions
such as asthma) to fog output.
• Do not point fog output directly at a person’s face
or at face height.
Tools
Make sure that the tools below are available before you
start working on the product.
• Pozi-driver #0, 1, 2
• Epsilon 5 Programmer (P/N: 50502004)
• Slotted screwdriver #0
• Temperature calibration box (P/N: 92620005)
• Digital multimeter with probes

Repair and maintenance
Heat exchanger calibration
The heat exchanger will require calibration after 1000
hours of operation or annually. This procedure will
take about 45 minutes to complete and requires the
temperature calibration box, available from Martin™.
This procedure is for qualied service personnel only
and only those competent should perform the task.
• For machines tted with analog PCBs
(manufactured before April 2012) follow the
procedure in “Heat exchanger calibration - analog
PCB” on page 8.
• For machines tted with digital mains PCBs utilize
the procedure in “Heat exchanger calibration -
digital PCB” on page 11.
Heat exchanger calibration - analog PCB
1. Power off the machine.
2. Remove the control panel access cover (four M5
screws).
Figure 10: Removing the cover
Figure 11: Lifting the cover
3. Lift the control panel access cover up.

Figure 12: Mains PCB
Figure 13: Disconnecting the thermocouple wires
4. Locate the mains PCB.
5. Disconnect the thermocouple wires from their
spade terminals, PL4 (1) and PL5 (2). See gure
12.
NOTE! If your machine was manufactured prior
to November 2006 these wires may be colored
green and yellow. Green is negative (-), and
yellow is positive (+).
6. Replace the thermocouple wires with the
calibration box leads.
NOTE! The correct orientation: Red is positive,
PL5 and black is negative, PL4.
7. Power on the calibration box.
8. Set the ramp button to off (LED ashing green)
and depress the VAR button (LED on steady red).
9. Use the variable slider to set the calibration point
to 11.5 mV.
10. Power on the machine.
Danger!
Take precaution to limit exposure to
live wires. Figure 14: Replacing thermocouple wires

11. On the mains PCB, adjust potentiometer P1 until
the red heating LED on the PCB starts to ash.
See gure 16.
12. On the calibration box, turn ramp button on (LED
on steady green). The red LED on the PCB
should go off.
13. For verication, turn the ramp button off (LED
ashing green), and the red heating LED on the
PCB should start ashing again.
14. Adjust if necessary following directions from step
11.
15. Power off and disconnect the calibration box.
16. Replace the thermocouple wires onto the correct
terminals.
NOTE! Thermocouple wires are colored black/
white and white. Black/white is positive (+), PL5
and white is negative (-), PL4. See gure 13.
NOTE! If your machine was manufactured prior
to November 2006 these wires may be colored
green and yellow. Yellow is positive (+), PL5 and
green is negative (-), PL4.

Figure 16: RedLEDisashing
Figure 17: Connecting a digitial multimeter
17. Connect a digital multimeter to the thermocouple
connectors. Positive to PL5 and negative to PL4.
18. Power on and set DMM to read mV DC.
19. Allow the machine to heat to the ready state.
DMM values should rise as machine heats.
20. DMM should read 11.5 mV when the machine
displays “RDY” and the red LED on the PCB turns
off.
21. Re-calibrate if necessary starting from step 7.
22. If no re-calibration is required, turn off and unplug
the machine.
23. Remove the DMM probes and replace the control
panel access cover and fasten the four M5
screws.
24. If re-calibration is not possible, the PCB may need
to be replaced. Contact Martin service for detailed
instructions to proceed.
