INTRODUCTION
Uni-ram holds many patents on designs used in its innovative products. Every machine is tested
for compliance with Quality Assurance standards. Follow the directions in this manual under Setup,
Operation and Maintenance in order to operate this machine safely and effectively. Not following these
instruction can lead to malfunction or damage to the machine. Ensure that the manual is readily avail-
able for the operator at all times. If you have any questions about the operation of this machine, call your
distributor or a Uni-Ram Service Engineer.
SETUP
DELIVERY INSPECTION
• Inspect the shipping carton for any sign of transport damage. Carefully remove the unit from the ship-
ping carton and check the unit for damage. Report any transport damage immediately to the carrier
and your vendor. Initiate a freight claim with the carrier. The manufacturer is not responsible for the
freight damage.
LEVELING AND AIR SUPPPLY
• Level the machine using the adjustable legs.
• Attach an air supply adapter (not supplied) to the Air Inlet.
The air supply pressure must be at least 85 PSI and the air must be free from contaminants such as
water, dust, rust, tar, grease etc.
To prevent damage to the Diaphragm Pump an internal Air Pressure Regulator has been installed to limit
the air pressure to precisely 85 PSI. Do not install a second air pressure regulator or use a pressure
set below 85 PSI.
If you have model, UG7500NGH, with hose cleaning, skip the next 2 sections on Pail Setup
and Operation for the UG7500NG.
PAIL SETUP AND OPERATION FOR THE UG7500NG
PAIL SETUP FOR UG7500NG

TROUBLESHOOTING PROCEDURES
PROCEDURE 1
Blocked Fluid Passage In Diaphagm Pump
If the pump sounds like it is working but liquid does not flow,
clear the fluid passage as follows:
• Remove suction tube from the pail and blow air at 85 PSI
into the INLET Liquid Hose (see diagram). Step on foot
pedal to activate pump. This procedure may have to be
repeated several times. If this procedure does not help,
blow some water into the suction hose using a spray gun,
wait one minute and step on foot pedal to activate pump.
This procedure may have to be repeated several times. If
this procedure does not work, the pump must be replaced.
If you need to replace the pump call your local dealer.
The warranty on the diaphragm pump is two years from date of
purchase.
This procedure will also clear a blockage in the fluid line for the
brush. Follow the same procedure to clear a blockage in the
automatic nozzle except turn the timer instead of stepping on the foot pedal.
PROCEDURE 2
Blocked Air Passage In Diaphragm Pump
If there is a steady hissing sound and the pump is not
cycling, the spool valve has stalled due to a blocked air
passage. Follow the procedure below to clear the blockage.
• Connect a blow gun to an 85 PSI source. Locate the
blue hose that extends from the air exhaust port of
the diaphragm pump. Use a blow gun to blow air into
the open end of this hose. Turn timer. If the procedure
is successful, the pump will start working. The proce-
dure may have to be repeated several times. If this
procedure does not work, replace the pump.
• Cause: Contaminants in the air supply (water, oil,
solid particles etc)
• Preventative Action: If necessary, install an Airline
(Moisture) Filter.
PROCEDURE 3
Blocked Passage in Air Line
The components in the air line are the diaphragm pump, air valve, foot pedal, 3-way ball valve
and regulator. See the Flow Diagram and the section: Replacement Parts.
To troubleshoot a component:
1) Disconnect the air line to the component using the quick disconnect.
2) Step on foot pedal and check for presence of positive air pressure in the air line. If there is ample
positive air pressure, replace the component.
If air pressure is absent, there is a faulty component upstream. Reconnect the air line and check the
operation of the next component upstream by following steps 1 and 2 above.
