Adjustable by-pass:

Sizes 1-1/4" and 1-1/2" come with a by-pass to restrict the flow rate passing through the Caleffi

XF magnetic filter and thereby increase the Cv value. However, 0% by-pass is recommended

during commissioning and for the first few weeks of system operation. Then, during the

"constant" phase, the XF magnetic filter can be set to operate with by-pass to achieve a higher

Cv. This reduces the pressure drop and puts less demand on the system circulators.

Additives dosing:

The Caleffi XF magnetic filter can also be used as an access point to inject chemical additives

into the circuit in order to protect the system.

Additives can be injected using

pressurized canisters.

Air vent:

The air that builds up at the top of the

body can be purged by unscrewing

the vent cap with a screwdriver.

Liquid additives can only be

added if shut-off valves have

been installed downstream

and upstream of the device.
