Specifications:
The FF13 is a 9Kw 3 phase industrial electric fan heater.
The appliance is connected to a 16Amp 3P+N+E 50Hz power supply and comes fitted
with the appropriate plug.
The machine is not phase rotationally sensitive !
The FF13 is fitted with a high quality forward curved motorised impellor which will allow
it to operate with up to 7.5m of 250mm duct. When using twin 150mm ducts, both ducts
should not exceed 10m total. DO NOT EXCEED THESE DUCT LENGTHS!
The FF13 is fitted with an internal thermostat as standard.
Setup and operation:
To start:
Please note ! the control panel is at the rear of the appliance. (See P7) •
Site the appliance on a firm level working surface or floor. •
connect to a 16 Amp 400v 3P+N+E 50Hz power supply. •
Switch the fan rocker switch to I. ( please note! the heater rocker switch will •
not operate the heating elements unless the fan switch is on).
Switch the heater rocker switch to I. •
Set the thermostat to the desired temperature. •
To stop:
Switch the heater rocker switch to 0 and allow the fans to run for a minimum •
of five minutes to cool the machine. Failure to follow this procedure may
cause the safety limit thermostat to nuisance trip and damage sensitive
components. This will invalidate the warranty.
Switch the fan rocker switch to 0 when the heat has dissipated. •
If the heater is not in regular daily use disconnect from the power supply. •

Using flexible ducting:
This appliance is designed to be operated with a maximum flexible duct length •
of 7.5m.
250mm ducting should be fitted. Do not use reducers. Where twin 150mm ducts are •
used the total length of the combined ducts should not exceed 10m.
Aluminium foil duct is recommended. Do not use plastic flexible duct. •
Always keep duct lengths to a minimum. •
Always keep duct runs as straight as possible. •
Poorly run flexible ducting can cause overheating of the machine. Do not •
run ducting through 180 degrees.
Acceptable duct runs:

Thermostat
Safety limit
thermostat.
Fan on/off switch.
Heating on/off switch
Circuit breaker.
The FF13 is fitted with a safety limit thermostat. This is a fail-safe device. •
Should the maximum design operating temperature be exceeded it will shut down
the heating elements and leave the fan running. This device requires a manual reset
and should only operate in the event of a fault. Any activation of this safety device
should be investigated by a competent engineer.
IT SHOULD BE NOTED! Failure to shut the machine down correctly can cause this
device to nuisance trip. See P5.
The FF13 is fitted with a limit thermostat. Should the maximum operating •
temperature be exceeded it will shut down the heating elements and leave the fan
running. This device will automatically reset once the temperature falls to an
acceptable level.
The control circuit is protected by a 7A circuit breaker. •
