Note: Starting up the system will require bleeding air and draining water from the valve.
Take proper precautions to protect your space from water damage.
STEP 1
Start with the upstream and downstream isolation
valves in your system closed, labeled 1 and 2 in Figure 1
respectively.
Begin by backing the adjusting screw on the LFCP15 pilot
valve all the way out by loosening the lock nut and turning the
adjusting pin just until it comes off the tension (See Images 1
and 2 below).
Ensure the inlet and outlet shutoffs on the pilot system are
open.
If your valve includes a speed control, loosen lock nut.
Set the valve to its fully closed position and back it off
approximately 11/2 to 2 turns from fully closed (See
Images 3 and 4 to the right).
The speed control can be fine-tuned once the valve
startup has been completed.
