test again to try and flush any debris that may be lodged
in the valve. If repeated tries fail to stop the leakage,
contact a licensed contractor or qualified service
personnel to replace the valve.
While performing a "try lever test", a quantity of heat
transfer fluid will be discharged from the piping system
and the system pressure will drop. This fluid must be
replaced. To refill and pressurize your system, we
recommend using a system pressurization appliance
such as an Axiom Industries model series. Capture the
discharged fluid in a container and recycle it by
returning it to the system feeder appliance. This is
particularly important when your system contains
treatment chemicals or glycol solutions. If the system
employs plain water, the boiler auto fill valve must be
turned on in order to recharge the lost fluid.
