Operating instructions

o If the fog is wet this is usually caused by turning up the volume too high. Only operate

at 100% (below blast on the remote control) or below 75% on the DMX fog.

o If the fog rises this is usually caused by turning up the volume too high, or not enough

refrigeration (see section 3.7). Only operate at 100% (below blast on the remote control)

or below 75% on the DMX fog. For short periods you can blast higher amounts of fog,

but continuous use will cause residue accumulation (see section 4.3) and raise the

temperature in the chiller causing rising fog. A 30-minute shutdown may be necessary to

cool the compressor. Shut off the refrigeration switch (left side) for 30 minutes and wait.

o If the fogger or chiller circuit breaker blows you most likely have one of the following

three fault conditions:

1. Low Line Voltage: occasionally the power company will be providing a voltage at

the lower end of the acceptable range, but most likely, this fault is caused by using

extension cords that are too long and of inadequate wire gauge. The 120V Polar

Controller

requires a 20 amp circuit, so the extension cord should be at least 12

awg (14 awg is too small). The 230V Polar Controller

requires a 10 amp circuit, so

the extension cord should be at least 14 awg (16 awg is too small).

2. Running too long in continuous operation: refer to section 3.7 to learn about the

Polar Controller’s

duty cycle limitations. The Rest Period is important to avoid

overheating the compressor in the chiller. You may pop the breaker on the

compressor or activate the over-temp breaker on the compressor motor by running

the unit too long. In either case the unit needs to be shut down for about 30 minutes

to cool off. Then you can try resetting the chiller circuit breaker. The over-temp

breaker auto-resets.

3. Internal short: If you are sure the voltage is adequate (90% of nominal) and you

have let the unit cool off, then resetting the breaker should get it running again. If the

breaker immediately pops again, then you probably have an internal short, which will

require factory service. See the section at the end of this booklet on service returns.

5.10 Notes on DMX Operation

1. Polar Controller

and DMX

CITC’s Polar Controller

Fog Unit has one DMX channel with 5-pin XLR to control on/off

and volume output of fog (there is no timer on this DMX).

The refrigeration unit has DMX. You may plug in the 5 pin XLR connector to the DMX

function and set the address for the correct address. This will turn on/off the cooling

portion (chiller) of the low-ground fogger when DMX control is above 50%. This unit uses

5-pin XLR connectors.
