Install Instructions

Step 2. Mount Switch

Insert the DB10 conduit connector through a knock-out

in the electrical box and secure with the nut as shown.

Switch must be positioned so

that diaphragm is maintained

in vertical plane.

Step 3. Installing Grommet and Tubing

Note: Gr

ommet should be mounted no mor

e than 30 inches fr

om the pr

sure switch in order to allow the tubing to reach from the switch to the duct.

First, drill a 1/4 inch to 5/16 inch diameter hole in the duct wall. Car

efully

insert the grommet into the hole. (Drilling a metal duct may produce

bur

rs. Be car

eful not to be cut or pricked by the bur

rs or the duct.) Next,

force one end of the tubing over the nipple on the switch. It may be nec-

essary to use a lubricant in order to slide the tubing over the entire nip-

ple. Make a mark a distance of 1/2 inch fr

om the other end of the tubing.

Slide this end of the tubing through the center of the grommet up to the

mark. Do not use a lubricant on this end of the tubing.
