8. The cover plate should be placed over the rectangular opening  
with its four mounting holes lined up with the four holes in the  
cabinet and the four holes in the mounting bracket (see Figure 7).  
9. Insert the four self tapping screws into the four holes until they  
engage the holes in the mounting bracket and tighten until they  
are secure (see Figure 8).  
10. Place plastic bezel over the installed switch and push towards the  
switch until the tabs snap into place (see Figure 9).

WIRING  
POWER DISCONNECT SWITCH (Available as a kit or  
factory installed option.) (KDS-1)This switch disconnects the  
power to power leads when the handle is rotated to the “0” posi-  
tion (left). The power is on when the switch handle is rotated to  
the “1” position (top) position. (KDS-2 and KDS-3) This switch  
disconnects power to the power leads when the handle is placed  
in its full lower position. The power is on when the switch handle  
is in its full upper position.  
ELECTRIC SHOCK HAZARD. Disconnect all power  
before installing disconnect switch. Failure to do  
so could result in personal injury or property dam-  
age. Disconnect switch must be installed by a  
qualified person and must be effectively grounded  
in accordance with the National Electrical Code,  
NFPA 70.  
1. Use the three pigtail leads supplied with kit (40 & 80 Amp) when  
connecting to the power line.  
For future replacement parts, the model number should be modi-  
fied on the nameplate to show that a disconnect kit has been field  
installed on the heater. A label kit (see Figure 14) (P/N 170-  
302788-002) has been included in the plastic envelope located in  
the disconnect kit. Cut off the appropriate number for the size dis-  
connect being installed (40 Amp = 1; 80 Amp = 2; 100 Amp = 3).  
The label has a pressure sensitive adhesive back so that the num-  
ber can be placed over the “0” as shown in Figure 14.  
a. Use No. 4GA Copper conductor wire only for 100 Amp dis-  
connect when wiring to the power line.  
2. The power disconnect wiring to the heater is to be made using the  
pigtail leads supplied on the heaters up to and including 25 kW.  
On larger heaters, the installer should supply 105˚C type AWM  
600V wire.

2. For units without contactors, disconnect switch is to  
be wired to lead wires on heater power.  
KUH-30 through KUH-45 units with 2 contactors  
where the total load does not exceed 48 Amps.  
3. Use copper supply wire only with this switch.
