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. -
Silicone Oil Level
Top up the silicone oil reservoir as per the following procedure:
• Ensure the correct oil type is used.
• Remove silicone oil reservoir blue cap by unscrewing (anti-clockwise).
• Slowly squeeze the Hill A72 silicone oil into the exposed hole until the lubricant level meets the blue max level line indicated on the reservoir. Ensure that the silicone oil uptake straw is submerged in the reservoir.
• Replace the blue cap finger tight (clockwise).
DO NOT MIX CRANK OIL AND SILICONE OIL DO NOT OVERFILL
-
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. -
Connecting to a vessel
Connect filling probe to hose, ensure spanner tight or use Quick Release Coupling fitted.
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.
Connect filling probe to vessel.
Ensure bleed screw is closed (finger tight).
Operating Instructions
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.
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.
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.
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.
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.
ACTUAL Pressure| Displayed pressure without trim| Displayed
pressure with
a trim of 101% + 1 BAR
---|---|---
100| 102| 100
300| 304| 300
Troubleshooting
-
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.
Shutting 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.
DO NOT LEAVE THE COMPRESSOR UNATTENDED WHEN IN USE!
IN THE UNLIKELY EVENT OF MALFUNCION, PLEASE CONTACT THE DISTRIBUTOR FOR
ADVISE BEFORE ATEMPTING REPAIRS.
PLEASE RETAIN THE ORIGINAL RECEIPT OF PURCHASE, AND ANY RECIEPTS FOR
SERVICE KITS PURCHASED.
