WARNING
Valves with pressure ratings other than specied are unsuitable and MUST NOT be used.
*Where required. For ratings see the table on page 12.
It may be a requirement that the hot and cold water supply pressures to a Temperature Limiting Device (TLD) are
equal. If this is the case, a PLV with the same pressure rating as the PLV for the hot water is required for the TLD
as shown�
