READ ALL INSTUCTIONS! WARNING: This unit operates with high voltage and has the ability to produce extreme temperatures. Failure to follow all instructions shown in this manual may result in serious injury or death. RECEIVING INSPECTING 1. Check the exterior of the shipping container or packaging material for obvious damage.
SAFETY SYMBOLS The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols and the explanations with them deserve your careful attention and understanding. The symbol warnings do not, by themselves, eliminate any danger. The instructions and warnings they give are no substitutes for proper accident prevention measures.
To reduce risk of injury to persons or damage to the CAUTION – unit, remove objects that can be moved by the Blown Debris cooling fans of the unit. WARNING – This unit can potentially operate at high voltage Electrical and current.
Extreme caution is necessary when any heater is used by or near children or invalids and whenever the heater is left operating and unattended. Always unplug heater when not in use. Do not operate any heater with a damaged cord or plug or after the heater malfunctions or has been dropped or damaged in any manner.
POWER AND GROUND CONNECTIONS Customer Cam-Lock Ground Connections WARNING: ELECTRIC SHOCK HAZARD. All power connections must be connected or covered.

Some important considerations when installing ducting with your heater: Only use ducting that can connect to the intake or exhaust adapters designed by Mosebach Manufacturing. Other adapter designs may allow you to connect incorrectly sized ducting which may result in heater failure.
EXHAUST TEMPERATURE WARNING: FIRE AND BURN HAZARD. Keep flammable material at least 40 feet away from the Heater. A great deal of heat is expelled from the Heater. Temperatures inside the Heater are sufficient to ignite flammable fumes or materials. Failure to maintain proper housekeeping and properly securing flammable material could lead to fire, burns, and/or injury.

• Using one thermocouple will control heater based on the local temperature of that thermocouple. • Using two thermocouples will control heater based on the average of the two local temperatures of thermocouples. • When placing thermocouple(s), keep ten feet from the unit and not in direct exhaust.
This is an indication that the internal cabinet temperature has exceeded 150°F. Over Temperature Make sure the cabinet is ventilated. Light Check over temperature sensors (OTS) see figure 4. This indicates the unit is not level. Tip Fault Light Do not try to operate unit while tipped or tilted more than 15° from horizontal. The heater has a built in voltage sensing system to protect itself.
