APOLLO ULTRASONIC OIL LEVEL MONITOR
THE RIGHT CHOICE
The Apollo Ultrasonic Oil Level
Monitor measures the level of usable oil in your tank in 10
graduations of the tank height.
We give a full 1 year warranty subject to normal conditions.
Supplied with long life lithium battery (3V-CR2430). The
warranty becomes invalid if the sealed unit is opened.
Suitable for use in tanks for the storage of diesel fuel,
kerosene, gas oil types A2, C1, C2, and D as defined by BS
2869. Check with the manufacturer and/or supplier before
using with any other fluids.
The Apollo Ultrasonic will fit easily to most standard oil storage
tanks (plastic or steel) that has a 20 mm, 32 mm or 38mm
(1½”) gauge hole.
TOOLS REQUIRED
Star/Philips head screwdriver.
INSTALLATION INSTRUCTIONS
1 SETTING RECEIVER
Accurately measure the height of your tank. Using the tank
height chart on page 2, read across to the relevant multi switch
settings. The multi switches are located in a recess at the back
of the receiver above the pins.
Using screwdriver or tip of ball point
pen, flip the relevant switch (es)
upwards (= ON). As an example, if the
tank is 850 mm high, set switches ON
(Up) Number 4 & 8.
Set switch 1 on/up to enable the low
level audible warning.
Your Apollo Ultrasonic receiver is now programmed to your
tank height.

MATCHING RECEIVER AND TRANSMITTER
You should match the receiver with the transmitter so that the
system code is unique to your tank.
You only need to do this once.
Plug receiver into a suitable and
convenient electrical socket and switch
on. The display screen on the front of
the receiver will show a flashing top bar
as shown in diagram. This indicates
that the receiver is awaiting a unique
code. The flashing top bar will last for 2
minutes during which time you can
match the transmitter to the receiver.
Hold the transmitter against the receiver
right hand side, as shown, so that the
black dots are touching each other
(important!) for about 20 seconds to
allow unique code to be transferred.
Bars will increase up the display screen.
During the matching process you will
hear an audible beep to indicate matching is in progress. A
change in tone will indicate completion of the matching
process. When all 10 bars are shown they will flash to
indicate that the unique code is transferred.

FITTING TRANSMITTER
The procedure is the same for fitting to
both old and new tanks.
For tanks with pre-drilled 20 mm or
32 mm hole
Remove cap from hole and insert
transmitter, ensuring the weather seal is
securely in place.
Ensure the transmitter is vertical on top of the tank.
Tighten on to the tank using the 2 stainless steel self-tapping
screws supplied. Do not over tighten. Do not use longer
screws.
For tanks with 1½” (38 mm) BSP gauge socket
An optional adapter is available
Unscrew cap from hole and fit the adapter provided by
screwing into gauge socket.
Fit the transmitter to the adaptor on the tank as described
above.
The Apollo Ultrasonic Oil Level Monitor is now fully installed
and signals should be received every hour. If the transmitter is
installed within 10 minutes of matching, the current level will be
displayed otherwise, it may take one hour for the correct oil
level indication to be displayed on screen.
NOTE:
Please ensure the receiver is plugged into an electrical socket
at all times. Do not unplug to reset.
In the event of a power failure or if the receiver is switched off
or moved to a new socket: When power returns again or unit is
switched on, the receiver display screen will show the top bar
flashing. There is no need to repeat the matching
instruction. The top bar will continue to flash for 2 minutes,
after which time the display screen will be blank, whilst the
unique signal is located. This may take up to one hour.
