The air injector has an air filter which should be cleaned once a week by removing it
and washing it in warm soapy water.
The air injector is connected to the jetter line as well as the milk line, with a valve
between the two.
This valve must be closed during milking and open during
washing.
CLUSTER WASHERS
Your
Waikato
Rotary Loopline
is fitted with Waikato G2 or Waikato NRV (non return
valve) cluster washers which allow you to place the clusters into the washers under
vacuum as you remove them from the last cows. Each unit also has a flow control valve
which is adjusted at the time of installation to ensure that sufficient wash water flows
through each cluster washer.
The cluster washers have nipples with screw (Waikato G2) or bayonet (Waikato NRV)
connections. In the unlikely event of a nipple being damaged simply remove it by
turning it anticlockwise and replace it with a new one. The rubber cups are pull off,
push on type. They should be replaced as and when they wear out. Air leaking past
the rubber cups will adversely affect the wash cycle.
VALVE SEALS
Your
Waikato
Rotary Loopline
has one main milk line valve and one jetter suction
valve which contain nitrile seals. The receiver and sanitary trap have two seals each.
These seals should be inspected annually and replaced if they are damaged.
MILK LINE SEALS
The
Waikato
Rotary Loopline
has stainless steel RJT unions containing seals joining
the milk line components. Inspect these seals twice a season and replace them if they
are damaged.
Check the unions monthly and tighten them if necessary. Air leaking into the milk line
through loose unions can cause excessive milk frothing.
CLUSTERS
Waikato Milking Systems NZ Ltd markets a range of claws, each with slightly different
maintenance requirements. All claws have rubber or silicone components (seals, shut-
off valves) and bowls which should be checked monthly and replaced if damaged. The
cluster air admission holes on all claw types should also be checked regularly and
cleaned if necessary.
Please consult your Waikato Milking Systems dealer for information on the claws you
have chosen.
