Start Up Procedure
AIR:
Slowly press the orange rocker on the air
valve to the down position to supply air to
the machine.
The valve is located on the left side of the
machine.
Check air pressure regulators inside the front door.
Left 80 PSI | Right 60 PSI
POWER:
Press the red rocker switch, just to the left
of the touchscreen, to the ON position.
WATER:
Empty the water buckets and wipe out
with 90% IPA or bleach, weekly to kill any
algae and bacteria.
Fill the clean water bucket with deionized
water that is 1MΩ or better.
After refilling the buckets, prime the wash
pump. Refer to page 23
1

Add more coating if needed by pouring it
directly into the coating bowl.
Start Up Procedure
Inspect the coating filter to ensure that
there are no air bubbles. If so, release
any air bubbles from the filter using the
bleeder cap. Refer to pages 19 & 22
** When bleeding air from the filter, make sure to only open the
cap a 1/4 of a turn and continue to hold on to the cap. This will
prevent the bleeder cap from blowing off from the pressure of the
coating pump.**
Prime the coating for 5 minutes.
Check the coating reservoir to make
sure the coating level is high enough.
The coating level should be at least ½
full.

Start Up Procedure
If it is not, use the adjustment knob
located on the top of the HEPA filter
blower unit.
Run one or more sample lenses to verify
that the lens is dry before running live
work. Refer to page 6
Using a KimwipesTM , hold it above the
front opening and check to make sure the
KimwipesTM is blowing away from the
opening at a 45˚ angle.
Check the coating height to make sure
it is level with the top of the coating
bowl. Refer to page 5
3

OTB Start Up Procedure
UV-Lamp Intensity should be greater than
70%, if less replace the UV-Lamp.
Wipe out the inside of the suction cup with a
lint free cloth.
Empty the trap at the bottom of the wash
bowl. Use teflon tape on the trap plug and
retighten. Do not overtighten, it only needs
to be hand tight.
Verify the water quality sensor is illuminated
green, indicating the water quality is 1MΩ or
better.

Press UV LAMP TEST

Checking The Coating Height
Press MACHINE SET-UP.
Press COATING PRIME.
Press VACUUM.
Chuck a lens on the suction cup located
over the coating bowl.
Press COATING ON/OFF.
Adjust the coating height to the top of the
coating bowl using the speed
potentiometer labeled “Coating Pump”.
Clockwise to increase.
Counterclockwise to decrease.

Dry Lens Test
Press PRODUCTION CYCLE.
Chuck a lens on the suction cup located
over the wash bowl.
When the wash pump starts to beat, count
how many times it beats before the air jet
turns on.
This needs to be 21 beats for the M/R III
and 26 beats for the OTB.
Allow the lens to complete the drying
cycle.
As soon as the spindle starts to come up
out of the wash bowl, press CYCLE
STOP.
Remove the lens using the foot pedal.
Wipe away any moisture from the front
side of the lens and inspect the backside
to ensure it is dry.
6

De-blocking & Lens Prep
Immediately after polishing, rinse the lens and
the block thoroughly with hot water before
placing it back into the tray.
The amount of time should not exceed 15
minutes from the time when the lens leaves
the polisher to when the lens is de-blocked.
The person de-blocking and removing the tape
from the lenses should not be the same person
washing the lenses.
If the same person has to do both jobs, then they
must always wash their hands and change to a
new pair of gloves before washing lenses.
This is to avoid carrying over any adhesive from
the de-blocking and tape removal process.
7

Use hot water and dish soap. Make sure the
dish soap is non-lemon. Ultra Optics
recommends original formula DawnTM dish
soap.
Change the water when the temperature falls
below 85° F.
Wash the lens with a sponge or alpha type
cloth. Make sure to replace with a fresh cloth
every 2 hours.
The time between washing the lens and
coating the lens should be no more than 20
minutes.
After cleaning, the longer the lenses sit there is a
higher risk of defects due to residual polish left on
the lens.
