SET UP
CAUTION - Please read and understand the following instructions
before use.
CAUTION - Once the compressor has been correctly filled with
lubricants, the compressor must be kept upright at all
times. Ensure the compressor is used on an anti-slip floor,
preferably placed on anti-slip matting.
1) Crank Oil Level
With the compressor positioned on a level surface, check that the oil
level meets the red dot on the sight glass.
Top up as necessary as per the following procedure:
— Ensure the correct oil type is used.
— Remove red crank case cap by unscrewing (anti-clockwise).
— Slowly squeeze the Hill A73 crank oil into the exposed hole until
the lubricant level meets the red dot in the sight glass. This
should approximately use a full bottle (50ml).
— Replace the red cap finger tight (clockwise).
DO NOT MIX CRANK OIL AND SILICONE OIL
DO NOT OVERFILL
After an oil change or fill, leave the oil to settle for 5 mins, if the
oil level drops below the red dot, top up with more oil until the level is
maintained.

3) Power connection
Insert the C13 power cable into the C14 socket on the left hand side
of the compressor.
Please avoid using any electrical extension leads if possible.
However, if you must use a third-party extension lead, this must be as
short as possible and must be rated to minimum of 110V / 16A
or 230 V / 13 A depending on your local power supply. If unsure,
please determine what your local power supply is before operating
the compressor.
4) Connecting to a vessel
Connect filling probe to hose, ensure spanner tight or use Quick
Release Coupling fitted.
Connect filling probe to vessel.
Ensure bleed screw is closed (finger tight).
CAUTION: If using a quick release coupling, always check and
make sure the collar on the female quick disconnect is
in the forward position and secure on the male fitting
you are connecting it to. It is recommended that you
check the connection by attempting to pull the female
and male ends apart while the fitting is in the forward
position before pressurizing.

Switching on power
Power up the compressor using the red switch on the left hand side.
The display will briefly show the Hill logo, the firmware version and the
running time.
Next, the compressor will request the user to confirm the lubricant
levels have been checked and are correct.
Press the rotary control knob to confirm the lubricant check. After this,
the display will show the first page of the main menu; the target
pressure display.
Operang Instrucons
Setting Target Pressure
The target pressure is the pressure at which the compressor will
automatically stop filling a vessel.
To set the target pressure, first navigate to the “Target Pressure”
display. This is the first display in the main menu, which appears after
the lubricant check described above.
With the target pressure display visible, press the rotary control knob
once to enable selection mode. A selection arrow will appear next
to the pressure value. With the selection arrow visible, rotate the
rotary control knob clockwise or anti-clockwise to Increase or
decrease the target pressure setting.
Once the desired target pressure is displayed, press the rotary control
knob once to confirm the target pressure selection. After confirming
the target pressure selection, the start display at the end of the main
menu will appear.

Rev 5 May 2022
Starting a fill
First navigate to the start display by rotating the rotary control knob
clockwise while in the main menu.
The start display shows the current cylinder block temperature and
the selected target pressure.
If the compressor detects that there is high pressure (roughly greater
than 70 BAR / 1015 PSI) in the system, this pressure will be displayed
on the lower left of the start display. The target pressure is displayed
on the lower right.
If no high pressure is detected in the system, only the target pressure
will be displayed.
With the start display visible, press the rotary control knob once to
start the compressor. After starting the compressor, the running
display will appear.
If the pressure in the system is low (roughly less than 70 BAR
/ 1015PSI), the display will show “Pressurising”.
If the pressure in the system is above this, the display will show
the current pressure on the lower left side and the target pressure on
the lower right.

Pausing a fill
A fill can be paused at any time by pressing the rotary control knob
once.
After pausing a fill, rotating the rotary control knob in either direction
will cycle between the option to resume or abort the current fill.
Auto Cooling
The compressor is designed to operate within a specific temperature
range. The operating temperature range varies depending on the
pressure in the system.
The compressor will automatically pause for cooling when it detects
that the running temperature has exceeded the maximum operating
temperature. This is normal and no operator intervention is required.
The compressor will automatically resume after a sufficient period of
cooling.
When auto cooling is in progress, the display shows the “cooling”
indicator.

Rev 5 May 2022
Auto Cut-Off & Depressurisation
When the target pressure has been reached, the display will show
“Fill Complete”. It is normal for the achieved pressure to reduce by up
to 5% after the fill has completed, particularly in smaller vessels. This
is due to the effect of cooling and flow losses. To compensate for this,
the user may wish to increase the target pressure, permitting that the
vessel is sufficiently rated.
DO NOT disconnect the vessel until the compressor has been
fully depressurised.
Depressurise the compressor by unscrewing the bleed screw; using a
rag for this is advised. Whilst depressurising, some moisture and
silicone may be expelled from the water separator.
Suitable precautions should be taken to protect any floor coverings
under the compressor.
The display will show the progress of the depressurisation.
When the compressor detects that the pressure is low (roughly below
70 BAR / 1015PSI) the display will return to the main menu.
The bleed screw should remain unscrewed to allow the compressor to
fully depressurise. After this, the vessel can be safely disconnected.
Lubrication check timeout
During long fills, the compressor will occasionally automatically stop
and request that the lubricant levels are checked.
At this time it is also necessary to fully bleed the water separator to
prevent excess moisture accumulation. If connected to a vessel
without a non-return valve, close the valve on the bottle and bleed the
compressor as described above. Users in particularly humid climates
may need to bleed the water separator more often.

Setting units of pressure
The unit of indicated pressure used throughout the operation of the
compressor is user selectable as BAR, PSI or MPa.
The unit of indicated pressure can be selected on the first page of the
settings menu. The settings menu is accessible from the second page
of the main menu.
Press the rotary control knob once to enter the settings menu.
“set units” is the first page of the settings menu.
Press the rotary control knob a second time to enable selection mode.
A selection arrow will appear next to the currently selected unit of
pressure.
Rotate the rotary control knob in either direction to cycle between the
selectable units. Once the desired unit is visible, press the rotary
control knob once to save the selection. The compressor will retain
the selected pressure unit, even after being powered off.
To exit the settings menu, rotate the rotary control knob clockwise
until “Main Menu” is displayed and press the rotary control knob once.

Trimming Calibration
The compressor is factory calibrated and should accurately sense its
internal pressure out of the box. It is however possible that over many
hours of use, some pressure sensor drift could occur.
To compensate for the occurrence of slight pressure sensor drift, the
compressor features a trim calibration setting. This allows the user to
apply a scale and offset to the factory calibration.
Trim calibration is the second page in the settings menu; accessed as
described in the previous chapter.
The default settings for trim calibration are 100% scale and 0 BAR
offset. It is NOT advised that users change these settings without
having observed a consistent inaccuracy in indicated pressure.
Sensor drift is not to be confused with the effects of post-fill cooling
as described on page 10.
NOTE: The trim calibration setting should NOT be used to attempt
running pressures higher than the maximum operating
pressure of the compressor (310 BAR / 4500 PSI). Changes
to this setting are recorded and any obvious intentional misuse
will void the warranty.
ACTUAL Pressure Displayed pressure
without trim Displayed pressure with a trim of 101% + 1 BAR
100 102 100
300 304 300
The scale and offset are applied to the TRUE pressure.
For a given target pressure setting:
A scale setting of 105% will increase the achieved pressure by 5%.
An offset of 5 Bar will increase the achieved pressure by 5 Bar.
As an example of how this feature can be used, consider a sensor
with a measured drift of +2 BAR at 100 BAR and +4 BAR at 300
BAR (as shown in the table below). To increase the accuracy of this
sensor, the following trim can be applied: 101% + 1 BAR.

Troubleshoong
- Compressor will not turn on:
Make sure that the power cable is inserted correctly and that the fuses in the power cable
plug and next to the compressor switch are present and functional.
- Pressure does not exceed 50 BAR and/or air escapes from the Pressure Relief Valve (PRV):
With the bleed screw open, run the compressor for 5 mins and then attempt another fill. If
the problem persists, contact your retailer.
- Pressure achieved in the bottle is lower than the target pressure:
The differential pressure across the bottle valve and hose, combined with the effects of
cooling may cause a small pressure loss. This will differ from one vessel to another.
Adjust the target pressure on the compressor to compensate.
- Motor will not start
As a built in safety feature the compressor will not start if the block temperature is
extremely low, due to the possibility of internal ice crystals. Thaw the compressor out in a
warm room to raise the block temperature.
Shung the compressor down
Make sure that the cylinder is removed and bleed screw is opened to release pressure. With the motor
at rest, turn the compressor off at the switch to the left of the consol.
Storage
Keep upright at all times. Do not store below 5°C (41°F)
Maintenance
Change crank oil every 50 running hours or once yearly (whichever comes first).
Unscrew sight glass to change Crank Oil (make sure you have a suitable container underneath) and
drain.
Regularly check that the Silicone lubrication is free from dirt and debris.
Service kits containing replacements for wearing components are available for specific running time
intervals. These intervals are: 50 hours, and 100 hours. The running hours are briefly displayed on the
console whenever a compressor is switched on.
Timely servicing is recommended to maximize the longevity of the unit. Heavy users such as clubs,
may find that they reach servicing intervals within the warranty period. in this case the services must be
carried out in order for the warranty to remain in force.
