water circulation in fully pumped systems, which employ a single pump for
both hot water and central heating circuits by allowing the flow to either or
both circuits using separate valves.

Operation
Installation
Valve position - In the event that
mains power is disconnected the valve
automatically spring-returns to the closed
position.
Override lever: For manually operating
systems to open valve for system
draining or filling. During normal
operation, the lever must be in the auto
position
The Z222 consists of a 2 port valve
body (Ref. B222) to which a self
contained actuator (Ref. A222) is
attached
POSITIONING OF VALVE
On new installations fit the Z222 valve
ensuring that the actuator head is NOT
below the horizontal level of the pipe
work and that the flow is in the direction
of the arrow. Also check that neither the
open vent or the cold feed are isolated.
This will ensure system and product
safety at all times. Remember to make
allowances for working, maintenance and
replacement.
