Strainer

 • 

 

Inspect the strainer screen at least twice during the first year. If 
fouled, inspect it more frequently.

Steam trap

 • 

 At  least twice a year verify that the steam trap is functioning 
properly. A blocked steam trap is cold. A "blowing" steam trap 
is hot and noisy, and the discharge pipe from it is hot for 30 
feet. A properly operating steam trap is hot and makes noise 
at intervals, and the discharge pipe is progressively cooler 
beginning at the trap.

Valves

 • 

 

Pneumatic 

Inspect annually to be sure the valve closes off steam tightly, the 
stem packing is not leaking steam, and the diaphragm in the 
actuator is not leaking air.

 • 

 

Electric modulating 

Inspect annually to be sure that the valve operates freely and 
closes off steam tightly and the stem packing is not leaking.

 • 

 

Solenoid type 

Inspect annually to verify proper functioning with steam-tight 
shut off.

O-Rings (slip couplings)

 • 

Inspect after two or three years of service, replace if necessary.

High-efficiency tubes

 

•

   If the insulating material gets torn, repair the tear with our 

Insulating Material Repair Kit before dispersing steam or  
moving air through the air handler to prevent further damage. 
This available kit uses tested and proven PVDF as repair  
material; do not use other adhesives or repair methods in place 
of the kit.

 

•

   If the insulating material gets dirty or smudged, gently clean  

it with a damp cloth and a solution of soapy water or diluted 
non-toxic, biodegradable cleaner/degreaser.

 

•

   Do not clean the insulating material with a pressure washer. The 

direct spray could cause damage.

 

•

   If using a torch in the vicinity of the dispersion panel, keep the 

flame away from the insulating material to avoid damage.

 

•

   PVDF is inherently resistant to UV light. Indirect, low-intensity 

UV-C light from germicidal lamps will not cause the insulating 
material to degrade.

 

•

   Do not tighten mounting clamps or fasteners to any part of the 

dispersion tube.
