Installation:
Contractors other than Hot Box are responsible for the installation of the G.F.I. protected service and receptacles, ref.
UL 943, NEMA 3R. When multiple heaters are required it is recommended that each heater be on a separate 20 amp
circuit so if a circuit fails, all other circuits will remain powered. All installations to be in accordance with local and
national codes.
Locate the aluminum heater plate(s) inside the enclosure and hang the heater(s) on the provided hangers.
Plug the heater into the ground fault circuit protected outlet.
Note: The heater assembly may be installed on any vertical wall no closer than 2 inches from the adjacent box wall or
seam.
Maintenance:
Perform the following maintenance prior to installation and at least once per season, preferably before energizing the
system each fall or immediately after any work has taken place on the piping system.
Check to be sure heater power cord is free from mechanical or thermal damage (cuts or nicks in the cable insulation
from utility knife, use of metal clamps, solder or overheating)
To test heaters with adjustable thermostats, the thermostat should be turned clockwise until the heater activates and
then reset to the minimum setting (40-45°F) by turning the knob counter-clockwise, after testing is completed.
To test heaters with the older pre-set thermostats, spray CO2 on the thermostat bulb to simulate cold temperature until
the heater activates.
Vacuum occasionally using standard vacuum attachments.
The heaters are intended to keep the equipment from freezing and are not to be used as a climate control de-
vice. Running the heaters for extended periods of time above 45°F will shorten heater life.
Warning! A ground fault circuit interrupting device shall be installed in the electrical supply circuit to this heater.
Failure to do so may result in injury or death. The interior of the enclosure is considered a damp
location.
Warning! Hazard of severe shock, disconnect all power before servicing.
Warning! Do not block air flow in any way.
Warning! Avoid contact. The heater surface is HOT.
For replacement heaters please contact your local Hot Box Representative.
