Use: The FLE-60 Electric Construction Heater is designed for temporary heat only.
The heater may be installed indoors or out and used to bring 100% outdoor air, or heat
and re-circulate building air. The FLE-60 is designed to heat large spaces, buildings
and machines without worrying about on site fuel.
Quality
: The FLE-60 is built with the highest quality of components giving our
customers the confidence they deserve in a Flagro product.
Convenience:
The FLE-60 gives our customers the flexibilty of a 20kW/40kW/60kW heat setting.
The heater is equipped with a fan speed inverter control that provides optimum temperature rise
by adjusting blower output at each heat setting. Colour coded Cam Locks power connections
for easy installation. Remote thermostat option available.
Inlet Duct Adapter
The FLE-60 includes a permanant inlet duct adapter.
Heater manufacturer approved ducting must be attached for outdoor use.
Safety
Always verify that you have proper voltage supply. (480V) It is important to check
the wiring connections inside the heater before plugging in the Cam Locks.
Use a meter to measure volt supply to each cam lock.
Work on the internal systems should only be attempted by a certified electrician and
only when power has been disconnected and can not be reconnected to the heater.
Grounding
The heater is supplier with a cam lock system with a grounding connection and is indicated with a "G"
on the cam lock panel. The heater is also supplied with a grounding nuts found on all panels.
It is very important to double check that all grounding connections are properly secure.
Clearance from Combustibles
The discharge temperature of these units may reach very high temperatures. Maintain minimum
distance from combustible materials as follows:
Top: 6 Inches
Bottom: 6 Inches
Sides: 6 Inches
Discharge: 15 FT

MAINTENANCE
1Every heater should be inspected before each use, and at least annually by a
qualified service person
2The appliance must be kept clear and free from combustible materials,
gasoline and other flammable vapors and liquids
3The flow of ventilation air must not be obstructed.
Be sure to check the fan assembly and ensure the motor and blade
are operating properly and it is important to clean air filters
4Compressed air may be used to keep components free of dust and dirt
build up.
Pre-Start Checklist
1 Heater must be level and lockable wheels must be in the lock position
2 Make sure blower switch and both heat switches are in the "OFF" positions
3 Make sure the air intakes are free from any obstruction(s)
4 Make sure the heater oulet is free from any obstruction(s)
5 Make sure the heater is properly grounded
6 Check power supply voltage and ampacity
7 If using the heater outdoors, heater manufacturer approved ducting must be attached to heater.

START UP INSTRUCTIONS
1Determine power source - 480V (confirm power source is correct)
2Remove top cover and inspect all wiring
(once complete, secure top cover to heater using the same hardware)
3Connect Flanged Camlocks to female camlocks ( colour coded)
Connect camlocks as follows:
Red A
Black B
Blue C
Ground G
3 PHASE UNIT CONNECTION
4Turn on power supply
5Pull "Master" button to the out position
6Determine "Manual" or Remote Thermostat (if remote, set desired temperature)
7Turn Blower on/off switch to the "ON" position
(The blower will start and the green air flow light will come on)
8Turn on heater settings as desired
( 60kW= 20kW & 40kW combined)
Failure to have proper air flow will cause unit to overheat and shut down
The green light should come on and air should be pushed through the outlet port
Check to see that only the green light is on.
Caution: Heater body panels will get very hot

Notes:
Speed inverter is pre-set for optimum air flow/temperature rise.
Based on kW selection, blower will adjust speed. See Chart below
