NOTE: Always use Genuine Graco Parts and Acces-
sories, available from your Graco distributor. If you
supply your own accessories, be sure they are ade-
quately sized and pressure rated for your system.
NOTE: Letters and numbers in parenthesis refer to the
callouts and the parts list on page 10.
Bring a compressed air supply line from the air com-
pressor to the pump location. Be sure all air hoses are
properly sized and pressure-rated for your system.
Use only electrically conductive hoses. The air hose
should have a 3/4 npsm(m) thread.
Before installing any air line components, blow out the
air lines to remove scale and other debris. Use pipe
compound or tape sparingly and only on male threads.
Install a bleed-type shutoff valve in the air line up-
stream from all other air line components, to isolate
them for servicing.
Electrical Service
Electrical power to the crossover is supplied by a
power cord.
WARNING
FIRE, EXPLOSION, AND
ELECTRIC SHOCK HAZARD
The electrical wiring shall be performed
only by trained and qualified personnel
to reduce the risk of serious injury and
electric shock.
Observe all local codes and regulations
regarding electrical wiring.
Installation
When installing in a flammable atmosphere (hazardous
location) refer to Article 500 of the US National Electric
Code or other applicable agency standards to plan the
work.
The operating voltage is 120VAC. This equipment re-
quires a 50/60 Hz, single-phase, 15 Ampere grounded
power supply.
Application
The electric crossover kit is designed to allow two
drum ram systems to be converted into a continuous-
flow system. It shifts pumping from an online ram
when the drum becomes empty.
Typical Electric Crossover Installation
Never leave fingers between the ram plate and the
drum when the ram plate is being operated.
Never enter the operating area of the ram , when
the ram is in the top position. When the air pres-
sure is lost or in the case of leaks in the air pres-
sure system, the ram plate may drop.
The typical installation, shown on page 4, Fig. 1 of this
manual, is only a guide. See the system manual for
your application or contact your Graco distributor for
assistance in designing a system to meet your needs.
See your ram manual if installing a new ram or relocat-
ing an existing ram.
