customers the confidence they deserve in a Flagro product.
Convenience:
The FLE-150 gives our customers the flexibilty of a 60kW/90kW/150kW 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 Lock power connections
for easy installation. Remote thermostat option available.
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

"OFF" positions
3 Make sure the air intake is 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

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
