OPERATION
1. Set the thermostat (internal or remote) to highest setting.
This will energize the heating elements and the fan causing
air to flow from the center of the heater.
2. After the operational check, set the thermostat to obtain the
desired comfort level.
Note: Heater contains a fan delay on shut down.
– The fan energizes immediately when the thermostat turns on
the elements.
– Fan will operate for a short time after the heating elements
are turned off (approx. 1 minute).
Field Conversion for Lower Wattage Rating
(Figure 13)
To convert the heater to a lower watt-age rating, completely
remove one (1) red jumper wire from one heating element for
25% wattage reduction. Completely remove two (2) red jumper
wires for a 50% wattage reduction. Discard the jumper(s). Be
sure the remaining wires are securely connected.
Conversion for 3Ø Installation
Heater is factory wired for connection to 1Ø only. To convert to
3Ø, remove and discard blue jumper wire between L1 & L3.
(Figure 13).
