INSTALLATION INSTRUCTIONS 
To install the MOTOR:  
1.  Connect the black wire from the motor to the switch Ⓢ (Figure 
8).  
2.  Connect the white motor wire to the piggyback terminal of the 
white element connector wire (Figure 8). 
3.  Slide shrink up over both white wires and connect white wire 
from cordset. Position shrink tube Ⓣ over all 3 terminals 
(Figure 8). 
4.  Assemble motor into housing and with (2) #6-32 x .50 long 
screws Ⓛ (Figure 1). Torque to 16 – 20 in-lbs. 
5.  Assemble (1) M3 x 0.5 Ⓚ (Figure 1) through back side of 
housing and into motor frame at a torque of 2-5 in-lbs. 
Excessive torque will warp the motor frame, resulting in reduced 
air flow and damage to the motor. 
6.  Assemble blower wheel onto shaft of motor and tighten set 
screw with 1/8 inch hex key. Top of blower wheel hub must be 
flush with top of motor shaft. Must not rub against frame of 
motor and must not rub against wiring (Figure 9). 
7.  Ensure electrical barrier Ⓥ is between wiring terminals and 
metal enclosure (Figure 8). 
To install the ELEMENT CONNECTOR: 
1.  Connect the black wire from the new element connector to the 
switch Ⓝ (Figure 7 & 8).  
2.  Connect the white motor wire to the piggyback terminal of the 
white element connector wire (Figure 8). 
3.  Slide shrink tube up over both white wires and connect white 
wire from cordset (Figure 8). Position shrink tube Ⓣ over all 3 
terminals.  
To install the CORDSET: 
1.  Install new cable ties in metal housing (figure 1). 
2.  Connect the green cordset wire to the enclosure’s ground post 
using the green screw (Figure 6). 
3.  Connect the black cordset wire to the jumper’s piggyback 
terminal attached to the switch (Figure 8).  
4.  Connect the white motor wire to the piggyback terminal of the 
white element connector wire (Figure 8). 
5.  Slide shrink tube up over both white wires and connect white 
wire from cordset (Figure 8). Position shrink tube Ⓣ over all 3 
terminals.  
6.  On 220-240V cordsets use supplied cord clamp (figure 10). 
To install the SWITCH / BEZEL ASSEMBLY: 
1.  Connect the wires to the appropriate switch terminals per 
instructions above (Figure 8). The black jumper wire is to wrap 
around the white wires from the motor and element connector, 
and the green wire from the cordset.
