OR
Unit is forming ice or frost on the
outer air coil, usually at the bottom.
Outside air temperature below operating range
of 45 F., unit is in "defrost" mode. Discharge
air flow is restricted. Discharge air is accumu-
lating and being drawn back through the outer
air coil. The fan is obstructed, low air flow.
Large amounts of roof run off water restricting
fan blade rotation. Sprinklers spraying on the
outer air coil during cooler temperatures. Outer
air coil clogged with debris. Plants too close to
heater, blocking air flow. Low refrigerant pres-
sure caused by a Freon™ leak. Possible mal-
functioning of the internal low refrigerant pres-
sure switch. Do not try to operate the heater when the
outside air temperature drops below 36 F
and 45 F with very high humidity or high
wind speed. Make sure heater is installed
with the required placement clearances for
air flow and roof clearance. Do not install
indoors. Make sure that your sprinklers do
not spray on the heater in any way what so
ever. If ice forms on the outer coil, shut the
heater off and allow ice to thaw. You may
use water at low pressure to thaw ice build
up on the outer coil, shut the heater off when
doing so. Call the factory for advice.
