Checking the Basic Pump Operation

3.1 Initialise the pump (Refer to Page 1, Section 1).
3.2 Connect a garment to each pump hose set assembly. Make sure the connection and garment
types are confirmed correctly on the display (Refer to Table 3).
Note: Although it is preferable to connect two different garment types to test the pump, the
pump can be tested with two identical garments or even just a single garment connected.
3.3 Press the green Run button
depressed until the pump "beeps". The green LEDs on the front of the pump will illuminate and
the compressor will start. Figure 16 shows the pump running, and the left calf garment inflated to
40 mmHg.
Note: The green LEDs do not illuminate when operating from the battery.
3.4 The pump provides intermittent cycles of compressed air to the two connected garments, which
are inflated alternately. During the test, check the LCD display to make sure that:
3.4.1 It shows the correct type of garments connected to the pump.
3.4.2 The correct pressure is being applied to each garment (Refer to Table 3).
Note: It is only necessary to check that the pressures are approximately correct.
3.4.3 No fault messages appear.
3.5 Check that the inflation hold time and cycle time are correct (Refer to Table 3).
Note: It is only necessary to check that the times are approximately correct.
3.6 Check the Lo alarm on the pump as follows:
3.6.1 Disconnect a garment from its hose set assembly while the pump is running, and check
that within one complete inflation cycle (which will be between 30 and 72 seconds
depending on the garment types connected to the pump), the pump will detect the fault
and flash Lo Alarm - Garment unplugged on the LCD display (Refer to Figure 17).
Note: If the garment is disconnected while it is actually being inflated, the LCD display
may initially flash Lo Alarm - Garment leak instead, followed by Lo Alarm -
Garment unplugged.
