Transport And Storage - Makita DVP181ZK Bedienungsanleitung

NOTICE:
The oil level is important. Operating the
pump in the condition with the oil level not between the
upper and lower level lines may result in malfunction.
Checking performance
► Fig.5:
1. Charging hose
(yellow)
2. Intake port
3. Vacuum pump
1. Connect the low side valve of the manifold and the
intake port of the pump with a charging hose.
2. Close the low side valve of the manifold.
3. Turn the pump on. If the pressure of the manifold
indicates a vacuum of -0.09 to -0.1 MPa within
30 seconds, the pump is operating properly.
4. Turn the pump off.

8. Service port (Low
pressure side)
1. Connect the pump, manifold and outdoor unit with
hoses.
NOTE: When the size of the service port on the unit is
1/4", use the supplied different diameter adapter.
2. Check that the high side and low side valves of the
manifold are closed.
3. Install the two batteries to the pump. (See "Installing
or removing battery cartridge" for the installation
method.)
4. Open the gas ballast valve.
5. Turn the pump on. The LED lamp (RED) lights up
and the motor operates.
6. Open the low side valve and high side valve of the
manifold.
7. Close the gas ballast valve after 5 to 10 minutes.
NOTE: The gas ballast valve is used to remove water
(vapour) and condensable gas (taken into the pump
during exhaust) from oil. If the condensable gas liquifies
and gets into oil, it can cause a decrease in lubricity,
and shorten the service life of the pump and seal. When
the air enters from the gas ballast valve, the condensed
gas remains as it is, and is exhausted with air.
It is recommended to warm up the pump before
operation because the more pump temperature is high,
the higher gas ballast efficiency can be obtained.

8. When the remaining capacity of the battery (on
the Left port) becomes empty, the power supply
automatically changes to the battery (on the Right
port). Remove the battery L, and replace it with
a spare battery. When the remaining capacity
of battery R becomes empty, the power supply
changes to the battery L again. The pump can be
operated for a long time by using the charged spare
batteries repeatedly for L-R-L-R.
WARNING:
The pump becomes hot during
operation and immediately after stopping. Do not
touch the area around pump while it is hot. Doing so
may result in burns or other accidents.
NOTE: The motor may not operate when it is cold (5°C
or less). In these cases, bring the pump indoors and
allow it to warm up.
9. When the specified vacuum (refer to the manual
provided by the air conditioner manufacturer) is
reached, close the low side valve of the manifold.
10. Turn the pump off.
Airtightness test
There are no leaks if the pressure of the manifold does
not rise for 5 minutes or more after leaving the pump and
manifold.
NOTE: When the battery remaining capacity becomes
low, LED lamp goes out and at the same time a long
alarm beep start sounding. About two minutes later
the motor stops. And then alarm beep changes into a
repeated short-time interval beeping which notifies the
motor stop and 30 seconds later the beeping stops.
However, do not wait until the motor stops (or alarm
beep changes to a short-time beeping), and instead
close the inlet valve of the pump and the low pressure
side valve of manifold.
Check that the pump is turned off, remove the battery,
and charge it or replace it with a spare battery.
• Refer to the following table for the battery operation
times.

• After finishing work, remove the battery and attach
the supplied cover.

Transport and storage

• Always drain your vacuum pump of all fluids before
shipping to prevent the damage of the container.
• Always cover the intake port with cap to keep any
dust from entering the pump.
• Be sure that the pump is kept in a horizontal position.
• The pump is stored in indoor ambient temperature
5°C – 40°C .
