IMPORTANT: THE PROPER MOTOR/FAN ROTATION, VIEWED FROM THE REAR OF THE HEATER IS OUNTER LOKWISE FOR THE SMALL ABINET UNITS AND LOKWISE FOR THE LARGE ABINET UNITS, AS INDIATED BY THE FAN ROTATION LABEL ON THE HEATER. INORRET ROTATION OF THE FAN WILL AUSE THE HEATER TO OVERHEAT AND YLE ON THE HIGH LIMITS. ONSULT FATORY IN ASE OF INORRET ROTATION. 7.0 MAINTENANE 7.1 The NORSEMAN explosionproof unit s are designed constructed operate in ugh industrial applications with a minimum of maintenance. However, some routine maintenance is recommended extend life of its components Always disconnect electrical supply before performing any maintenance. 7.2 Periodically inspect installation ensure that all connections, fittings, plugs, screws, covers, etc. are tight free of corrosion. 7.3 heck inside of cabinet around element fins for dust buildup debris, especially after seasonal shutdowns. lean with an air blast or vacuum. Ensure that nothing is restricting air flow in unit that blade is free rotate. 7.4 MOTOR The mor supplied with small cabinet units is approved for lass 1, Group D, lass II, Group E, F & G, T3B code. The mor supplied with large cabinet units is approved for lass I, Group & D, lass II, Group E, F & G, T3B code. All mors have internal rmal protection eliminate mor overheating. 7.5 FAN BLADE Visually inspect blade ensure it is free rotate accidental damage has not occurred. If bent or damaged, a facry balanced blade should be installed so that rated airflow is maintained. A damaged blade may not deliver required airflow over elements, resulting in cycling on high limit which can significantly reduce life of contacr high limit. 7.6 HEATER ABINET ycling of high limits should not be permitted. Should this occur, unit should be inspected determine cause of cycling condition should be corrected. 8.0 REPLAEMENT PARTS LIST The replacement parts list is included for reference only.
