SECTION 1 | GENERAL INFORMATION & OPERATING PROCEDURES
Flush & Fill Cart SFFC-70/2 | 13
The following coolant system components are located on the Flush and
Fill Cart.
COMPONENT DESCRIPTION
Tank Shutoff Valves
This gate valve is located at the tank outlet
into the pump suction line. When closed, this
valve allows service to be performed on the
system without draining the tank. (V6 & V7)
Tank Drain Valves
This gate valve is located underneath the tank
to allow coolant to be drained from the tank.
Filter
The filter between the supply hose and the
pump filters impurities from the coolant
leaving the pump. This filter is a 5-micron
absolute filter and has a removable element.
Y Strainer
The strainer prevents particles from entering
the pump. The strainer is located just after
the tank shutoff valve.
Pump
The pump delivers coolant from the coolant
tank to the aircraft. This diaphragm pump is
belt-driven by the motor and runs whenever
the motor is running.
Meter
The meter measures, in gallons, the amount
of coolant pumped to the aircraft. The meter
is directly above the main valves. It may
be reset to zero using a knob on the meter
housing.
Sight Glass
The sight glass allows the operator to visually
see that coolant is moving through the service
hoses and into the waste tank.
Check Valves
Two check valves are installed in the system.
They are located before valve 4 to ensure
that coolant does not flow back through the
strainers and into the tanks. Refer to the
coolant schematic (Fig. 1.1.1.2)
1.1.1.3 | Electric Motor
The motor is mounted parallel to the pump in the center of the cart. The
drive shaft of the motor drives through a belt to the diaphragm pump. Op-
erating controls for the motor are located on the control panel.
1.1.1.4 | Electrical System
The electrical system for the cart is a 480 volt three phase AC system.
