Cold Climate Kit
A cold climate kit provides heat to the pulse valves
to prevent cold weather freeze up. The basic kit, for
use in applications that have a moderate amount of
moisture in the compressed-air supply, consists of a
small heating element and thermostat installed in the
solenoid enclosure. The basic kit is factory-installed
and supplied with the appropriate solenoid wiring
instructions.
A heavy-duty kit is available for applications that
have moderate-to-high amounts of moisture in the
compressed-air supply and consists of the basic kit
plus a heat cable to deliver heat to the large pulse
valves. This kit is customer-installed and detailed
installation instructions are provided.
1. Install the power connection kit on the heat
cable following the manufacturers instructions.
2. Start with the upper right-hand valve, wrap heat
cable around the valve as shown in
Detail A. Pull heat cable tight.
Note: Double wrap between round coupling and
square valve cover.
3. Position a 3-in hose clamp around the double
wrapped heat cable and tighten securely.
4. Wrap remaining valves using the same technique
in the order shown in Detail B.
5. Drill a 1-in diameter hole in the back of the
junction box. See Detail C. Assemble the power
connection kit following the manufacturers
instructions.
6. Secure junction box to manifold using two 8-in
hose clamps wrapped around the standoff.
7. Wrap 6-ft of pipe insulation tape around each
heat-cable wrapped valve. Wrap the entire valve,
double wrapping the hose-clamped heat cable.
Secure with cable ties.
