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.

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

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)

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
