MOUNTING & HANDLING
2.1.
Mounting:-The Atomiser is normally operated in the vertical position with
the rotating Spray Head at the bottom, and the liquid input
to the Feed Tube at the top - as shown in the diagram, but the
unit can be used at an angle too, provided the Spray Head is
always lower than the liquid input. Operation upside-down
however, ie. with the Spray Head at the top and the liquid input
beneath is not possible - this way the shaft can fill
up, leading to flooding of the Atomiser's bearings.
There are six
vent holes in the underside of the Electronics
Housing - they allow any liquid overflow inside the unit to
escape and must not be sealed, nor should
any mounting block them.
A special Mounting
Kit, including a padded bracket suitable for holding the Atomiser
is available from Newland
Design. It fits around the Motor Housing, and leaves the vent holes clear.
Suspending the Atomiser is acceptable provided the weight is taken by the
Power Lead, and not the Feed Tube (but check the cable gland
is tight). Do not suspend the unit by the Feed Tube.
The high rotational
speed of the Atomiser can give rise to noise and vibration if
it is not carefully mounted. Ensure that mountings are firm,
with no loose screws &c..
The Atomiser
warms up during running, reaching 40 - 50° C in normal ambient
temperatures, after about 15 minutes.
2.2.
Weight:-The standard Atomiser
in stainless steel weighs 750 g; about 1 kg with packaing.

Operating & Storage Temperatures:-
1. May be extended to
85 ° C for short periods.

2.4.
Wetted Parts:-
In the standard unit, these
are made from the following materials: stainless steel alloys
304, 316 (AISI), 1802(Sandvik); porous and non-porous polypropylene.
In addition
at the top of the Shaft, inside the Electronics Housing (at
"X" in the diagram 1.3.) there is a Nitrile seal seated
on a sleeve of PTFE with 25%-Graphite fill: the seal can be
omitted from assembly on special request to the factory at time
of ordering.
2.5.
Handling Precautions:-
The Atomiser incorporates precision bearings
and high-quality machining and should be protected from severe
shock and mishandling.
The Spray Head should be protected from contamination by dirt or grease.
The Spray Head should be inspected regularly, and replaced
if distorted, cracked, or very dirtySpare Spray Heads are available from Newland
Design; for replacement procedure, see 6.3..
Nothing should be attached to the Spray Head; the rotating parts of the Atomiser are dynamically balanced
to give smooth running, and any additional mass can cause vibration
of the Feed Tube, or undue wear on the bearings.
