Installation guidance
The unit should be mounted horizontally, and while any other position will work the switch flow may change. There are bulkhead mounting
holes available on the counter box but these should not be used to support pipe-work connected to the ports. Any pipes that can move during
normal operation should be locally clamped to prevent excess stress on the ports.
The unit will allow reverse flow to pass without excessive pressure drop, but it will not trigger the counter.
The design is tolerant of some fluid contamination, but it should be kept below NAS 8 or ISO 19/17/14. A maximum 40micron filter should be
installed in the circuit.
Rapidly changing or pulsating flows should be avoided.
