Rear fan diagnostics
The rear fans should be visually and audibly checked
for operation every 250 hours for correct operation. The
rear fans are what propel the fog from the machine and
are vital to operation.
To verify fan operation simply operate the machine
manually from the control panel.
1. Turn on “ICE” and “Standby” then allow the
machine to get to its ready state.
2. Once ready, set fog output at 10 on the left hand
display and density to “Hi” on the right hand
display.
NOTE! The fan speed should be low and the fan
noise should match that speed.
3. Set density to “Nor”, the fan speed and noise
should increase.
4. Set the density to “Lo”, the fan should now be
operating at full speed.
If the fan speeds do not change or the fan is not
running at all, contact Martin™ Support for service and
support.
Sight glass level check
Inside of the uid compartment is a sight glass
for visual indication of the refrigeration’s systems
operation. Check this sight glass every 1000 hours
or annually, alongside the refrigeration system check,
“Refrigeration system check” on page 17.
1. Open the uid compartment door and locate the
sight glass.
NOTE! A ashlight or work light may be necessary
to better illuminate the space.
2. With the machine powered on and in its ready
state but not producing fog, observe the sight
glass.
There will be visible liquid level rising and falling in
the sight glass.
3. There is no dened level but the rising and falling
should time with the expansion valve opening/
closing, which can be audibly observed by the
clicking/surging noise the machine’s emits,
approximately every 10-15 seconds.
4. If no level is seen and clicking noise is more
frequent than normal, a possible refrigeration leak
is possible. Contact Martin™ Service for service
and support.

Condensate drain
When operating the machine for long periods, there will
always be a buildup of condensation in the evaporator
unit. This will drain into the drip tray, which should be
emptied and cleaned regularly.
For installation purposes, a drain hose can be tted into
the condensate drain hole.
A visual inspection of the condensate drain should be
performed every 500 hours or semi-annually. When
performing an inspection, it is only necessary to verify
that waste water is properly draining from the drain
hole or drain hose.
Caution!
Isolate the machine from power and
allow it to cool completely before
performing the following procedure.
1. If the drain hose or drain hose appears to be
clogged, clear the obstruction.
2. Use a small slotted screwdriver or an awl and
simply dislodge any debris out of the way of the
hole or clear the hose.
3. If an obstruction cannot be cleared contact
Martin™ Service.
