COMPACT 1.4
• Proceed according to paragraph E.
• Vacuum in each circuit during 30 minutes and introduce 250 g of R134a in each one of the
circuits.
• After verifying charge, check pressures and in case they are below 0.5 kg, while equipment is
working, clean circuits or replace obstructed component (possibly capillary tube).
• Cool down for a while using the vehicle's Air conditioner and then use Compact / Place vehicle
at shade. Minicool Compact is designed to use during rest period and at night time.
• Fit the front canalisation system to the Compact base.
• Verify pressure, the lower the temperature, the lower the pressure. As a maximum reference,
they must be between 2.6 and 3 bars in both circuits, if outside temperature is between 30º
and 32º. (One circuit must always have a slightly higher pressure).
• Proceed according to paragraph E.
• Dismantle and clean obstructed component and if necessary, replace it. (1).
• Leave recirculation entry, situated at equipment base, free.
• Clean condenser / grid.
• Replace electro fan.
• Check that air is expulsed outside equipment, if not, invert connector connection.
• Correctly place joint or replace it (it is very important to properly clean the surface where joint
will be assembled).
• Clean draining pipes and place the draining valve.
• Replace electronic control or controls plate.
• Connect the tape with connectors correctly.
(1) Each time it is necessary to extract or introduce gas charge out of/in circuit, it is necessary to
do it using adequate machinery and always respecting the environment. The refrigerant gas
recovery will never be accurate because part of this gas will remain inside the presure gauge
pipes.
