It is recommended the supply connections to the manifold are direct
from the primary heating circuit, prior to any zone valves or control by
other emitters or devices. Interlock should be established between
the underfloor heating and the heat source. Failure to do so can lead
to instances where the primary supply is not active when it is when
required by the underfloor heating.
The sizing of the primary supply should always be calculated,
properly accounting for the design primary flow rate.
The WHS-M-S3-VALVES have Female 1” G connections to the primary
supply. The pack also includes a pair of 22mm compression fittings,
allowing 22mm pipe to be connected directly to the manifold where
applicable.
NOTE
: PTFE or similar should be used to connect the 22mm
compression fittings to the 1” Isolation valve if used.
