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.
2

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 SYSTEM DETAILS
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.
5

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.
8

Procedure For Coating Lenses
Press PRODUCTION CYCLE.
Place trays in order.
Press ON/OFF on touch screen so that
the green bar is towards “ON”
9

Pre-Coating Lens Prep
Put on a clean pair of approved Nitrile
gloves.
Hold the lens backside up.
Keep fingers only on the edges of the
lens.
Squirt a quarter size amount of 90% IPA
or UOC Lens Cleaner on the backside of
the lens.
Using a finger with light pressure, clean
lens using a circular motion starting from
the center and moving towards the
outside edge.
Hold the lens in a vertical position.
Rinse the lens off into a waste container.
This will ensure the lens is as clean as
possible.
10

Chuck the lens onto the suction cup over
the wash bowl.
Check that the lens is centered before
removing your hand from window.
If the lens is not centered on the suction
cup, press the foot pedal to release and
rechuck.
Procedure For Coating Lenses
Continue this procedure until there is a
lens ready to be removed.
Press the foot pedal and remove the
coated lens above the wash bowl.
Chuck the next lens onto the suction cup
over the washbowl.
11

Procedure For Coating Lenses
When there are no more lenses to coat,
remove the lens above the wash bowl.
Hold LAST CYCLE until the button turns
green.
This will finish the remaining lenses in the
machine.
**DO NOT attempt to load any lenses
once LAST CYCLE is activated**
Make sure that all coated lenses have
been removed from the spindles.
Press ON/OFF on the touchscreen so that
the RED bar is towards “OFF” to
deactivate spindle vacuum.
12

Lens Care After Coating
The lenses must sit for a minimum of 45
minutes before edging or tinting.
The reason for this is to stabilize the lens
material after the coating process.
Keep lenses away from constant water
contact and allow airflow underneath to
prevent fogging.
Cleaning the lens is okay, but avoid
contact with wet areas like dirty trays.
Before tinting, Ultra Optics recommends
cleaning the lens using the Lens Wash
Procedure.
Refer to page 8

Preventive Maintenance
Daily
Wipe out wash bowl and deck area with a
clean damp lint free alpha type cloth.
Check air pressure regulators inside the
front door. Left 80 PSI |Right 60 PSI
Wipe out inside of coating bowl with a clean
lint free alpha type cloth slightly dampened
with Acetone or 90% IPA.
Rinse wash bowl and coating bowl screens
with Acetone or 90% IPA, replace as
needed.
14

Preventive Maintenance
Daily
Check that the coating height is up to the
top of the coating bowl.

hours.
**Ultra Optics guarantees the UV Lamp up to 800
hours and pro rates any returns under 800.** 15
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.

The coating level should be at least ½
full.

Preventive Maintenance
Weekly
Visually inspect the suction cups and water
deflectors for any deterioration. Replace as
needed.
Check the spindle speeds at each spindle.
Check that the lamp cycle time is at 24
seconds. If it is not, adjust by using the
speed potentiometer labeled LAMP.
