Preventing burns and fire
•The fog produced by the machine is hot enough to cause burns when it
leaves the nozzle, and very hot droplets of fluid escape occasionally.
Keep people and objects at least 60cm (24 inches) away from the fog
output nozzle.
•Do not touch the fog output nozzle during or after use – it becomes
extremely hot and remains hot for several hours after the machine has
been shut down.
•Fog output contains glycol, a flammable alcohol that burns with an
almost invisible blue flame. Do not point fog output at sources of ignition
such as open flames or pyrotechnic effects.
•Do not attempt to bypass thermostatic switches, fluid sensors or fuses.
•Replace fuses only with ones of the type and rating specified in this
manual for the machine.

14 Installation and setting up
Before connecting the machine to power, verify that the AC supply is adequately
dimensioned for the current draw of the machine.
1200W 240V EU / 1000W 120V US
1550W 240V EU / 1450W 120V US
2100W 240V EU / 1800W 120V US
Check that the local AC voltage is appropriate, as indicated on the machine’s
serial number label. If your AC voltage is outside the appropriate range, do not
use the machine. Contact Martin™ Service for assistance.
Setting up
Fill the fluid tank with a suitable JEM™ fluid as shown on page 20. If DMX control
is being used, connect the machine to the DMX line (see page 19).
If you are using several machines from one control panel in master-slave mode,
link the machines in a daisychain using the DMX input and output sockets. It
does not matter which socket is used as input or output.
Final checks
Before applying power to the machine, verify the following:
•the machine is safely located or installed and meets the location
requirements stated on page 13
•the operator is familiar with, and able to comply with, the requirements
for safe operation listed on page 5.

DMX control 19
DMX control
Overview
DMX is a digital control system widely used in entertainment and architectural
lighting. Any controller meeting the DMX-512 standard may be used to control
and program the fog output of the JEM ZR series™ machines.
When a DMX signal is present, the
J
EM ZR series™ machine
’
s
stand-alone functions do not work. To fire the unit from the control
panel or remote control, the DMX controller must be powered off or
disconnected.
If the DMX signal is removed (controller turned off or unplugged),
the machine will revert to its previously stored RUN MODE settings.
If the machine was set to OFF it will revert to this state.
If the machine was set to STANDBY it will revert to this state.
If the machine was set to TIMER it will revert to this state.
If the machine was set to CONTINUOUS it will revert to this state.
Connection
The JEM ZR series™ machine provides 5-pin XLR connectors on the rear of the
machine for DMX connection.
For best results, use cable designed for high speed digital data transmission.
Suitable DMX cable is available from your Martin™ dealer.
DMX functions
The JEM ZR series™ address setting must match the DMX address allocated to
it on your controller. To set the address, see “Setting the DMX base address” on
page 16. The JEM ZR series™ machine requires one DMX channel.
When the machine is at running temperature and is under DMX control it
displays DMX (+ the current DMX base address).

20 Fog fluid types
Fog fluid types
The JEM ZR series™ machines must only be used with the JEM™ fluids listed
below. Martin™ supplies high quality fog fluids that are based on ultra-pure
deionized water. No other fluid is suitable for use.
Regular DJ Fluid (DJ mix)
Regular DJ fluid is an economical fluid that gives a good, medium density
smoke well-suited for atmospheric effects.
Pro Smoke Super (ZR mix)
Pro Smoke Super fluid is a high-quality, general purpose fluid that produces a
dense white airborne fog with medium dispersal time. Its medium to high index
of refraction permits both good atmospheric effects and denser “white-outs”.
Pro Smoke High Density (SP mix)
Pro Smoke High Density fluid generates a high density, white, airborne fog with
a very high index of refraction and slow evaporation rate. It is well suited for
scenic obscuring, dramatic strobe effects, and “white-outs”.
Pro Steam Simulation
For ZR45 only - Pro Steam Simulation fluid is a light fluid that
produces well-defined cones of vapour that disperse quickly. It is
ideal for chase effects and theatrical use. Not suitable for ZR25
and ZR35.
TEMPERATURE MENU
The different fluid types listed require correct selection of the relevant
temperature setting in the TEMPERATURE sub-menu of the SETTINGS menu.
Select the required temperature and press Enter to store.
The selected temperature setting will remain after power off and is indicated on
the display whilst in standby (TEMP=NORM) and also shows during manual
operation/DMX control (T=N).

DANGER! The JEM ZR series™ machines can run safely only on the specific
fog fluids they are designed for. Use ONLY the JEM™ fog fluids designated in
this manual. NEVER use any other type of fluid, or toxic gas may be produced.
You will probably also cause damage to the machine that will invalidate the
product warranty. Do not dilute fog fluid with water or any other liquid. Discard
fog fluid if it becomes contaminated.
