consult an authorised supervisor.

Installation

Performance

To achieve standard performance, the Atlas Copco
WAP 2 water pump requires a nominal oil supply of
20 lpm (5 US gal/min) at a pressure of min. 100 bar
(1400 psi), and the WAP 3 trash pump requires a
nominal oil supply of 30 lpm (8 US gal/min) at a

Hoses

For connection on the machine, the hydraulic hose
must be approved for a working pressure of at least
160 bar (2,300 psi) and have a 12.7 mm (½ in.) inner
diameter. To resist exterior wear and tear, we
recommend using a 2-layer hydraulic hose. The
machine connection marked P (pump) is the oil inlet,
and the connection marked T (tank) is the oil outlet.
Always connect both hoses and make sure that all
hose connections are tight. Never carry the machine
by the hose.

Quick-release couplings

The original hydraulic hoses are fitted with Flat-Face
quick-release couplings that are strong and easy to
clean. The quick-release couplings are fitted so that
the male connection supplies oil and the female
connection receives oil.
NOTICE Wipe all couplings clean before
connecting. Ensure that couplings are clean and
correctly engaged before operation. Failure to do so
may result in damage to the quick couplings and
cause overheating and cause foreign matter to enter
the hydraulic system.

Hydraulic oil

In order to protect the environment, Atlas Copco
recommends the use of biologically degradable
hydraulic oil. No other fluids must be used.
