OPERATIONAL TIPS
1. Always use Cirrus/Cirro fluid. Operation with any other liquid will invalidate the guarantee
and invalidate the COSHH health and safety approvals for the unit.
2. The Cirro Strata machine incorporates the CIRRUS system which has been COSHH tested in
the UK. It is on the approved list for use in areas of public entertainment. Certificates are
available for inspection if required.
3. The machine will provide a fine even mist. The recommended level for use in an eight hour
day is 5mg/CuM (reference OSHA), and this represents a fine mist, NOT fog or smoke.
When the mist is just visible with the eye, this represents a maximum working concentration.
4. Position the Strata downwind of the prevailing draught, If required an additional fan can be
used , but this must always BLOW the mist. Never extrude the mist through the fan as this will
result in loss of output and heavy fluid build-up on the fan blades.
5. The mist will always rise or fall to the coolest areas. In very humid conditions, use of a heavy
duty fan might be required to avoid the mist becoming localised.
6. Never use a hose on the tank top output (5) as this will result in loss of output.
7. It is NOT important to position the tank near to where the mist is required as this type of effect
is ambient rather than localised.
8. When the desired effect is achieved, switch the machine off, and then switch on again as
necessary. Do not just leave the machine running as this will result in too high a concentration
of mist. Since the desired effect will be dependent on the Directors requirement and ambient
conditions of temperature, humidity and prevailing draughts, it is suggested that some
experimentation is carried out prior to use.
9. NEVER block the supply of air to the fan located on the underside of the compressor case.
This is essential for the cool operation of the compressor as well as providing air for the
compressor input.
10. The tank output incorporates a removable foam silencer pad. Should the absolute
maimum mist output be required then this filter can be removed, although audible tank
noise will increase slightly and fluid residues will need periodic wiping from the tank top
plate.
11. If absolute quietness is needed, the Strata case should be split so that the compressor section
can be remotely sited. Externsion hoses are available as optional parts. Refer to the section
‘Two Part Operation’.
12. The air supply to the tank is filtered to remove any moisture content. The filter is located on
the bulkead panel of the tank case and is supplied set for automatic draining. The small
amount of water collected will drain through the pipe onto the floor beneath the case. In
situations where this is not acceptable the drain should be locked off by rotating the knurled
ring on the base of the filter cup, to the right. Regular draining should then be undertaken by
temporarily resetting the knurled ring to the automatic position with the unit switched off.
