The Robo-Vac is designed for trouble-free operation. When
installed and operated properly, the Robo-Vac will provide
years of reliable service collecting and discharging
condensate, along with pipe scale and other contaminants
typically found in vacuum systems.
INSTALLATION
Before installing the drain, ensure the source vessel is
isolated from the interconnecting piping to the drain.
Confirm the air system pressure will not exceed the 90 PSI
(6.2 bar) rating of the drain and the inlet temperature should
not exceed 180
o
F (82
o
C).
The condensate source must be connected to the ¾” NPT
inlet connection on the pinch valve. The installation of a pre-
strainer is not required or recommended.
Install the drain on a level surface and as close to the source
to be drained as possible. Since the Robo-Vac uses gravity
to fill the reservoir, the entire drain must be installed below
the source. It isn’t recommended that flexible tubing be used
on the discharge to prevent it from whipping casing damage
or injury.
If the drain is to be installed where the temperatures can fall
below 32
o
F (0
o
C), special precautions are needed, including
but not limited to heat tracing pipelines and the optional
immersion heater.
The Robo-Vac will only accept condensate via the pinch
valve connected to the upper drain inlet connection. The
lower inlet connection has been permanently sealed to
prevent inadvertent use.
The use of isolation valves and bypass piping will permit
quick and easy routine maintenance.
The Robo-Vac uses compressed air to drive (control) a drain
cycle.
ONLY CLEAN DRY AIR MUST BE USED!
The
required control air pressure for the standard models,
irrespective of system pressure is 60-130 PSIG (4.1-9.0
barg). The Robo-Vac can be supplied as an LP variant and
will model should be between 40 and 130 PSIG (2.8 and 9.0
barg).The Robo-Vac is supplied with a filter for installation
on the control head. The use of unfiltered air can result in
failure and can void the product warranty.
Once installed and control air supplied, the drain is ready to
be placed in service.
CHECKING THE OPERATION
After installation is complete and the drain is in service, a
check should be made that the drain is functioning properly.
1. Ensure that condensate is properly entering the
reservoir. This can be easily done looking through the
translucent reservoir
2. Press the test button to ensure the drain valve opens and
closes when the button is released.
3. Inspect for any air or condensate leaks. Correct as
necessary.
TROUBLESHOOTING
If condensation is not entering the reservoir, check for the
following:
1.
Check that any valves between the source and drain are
open.
If the drain is not emptying:
1. Press the test button to force a manual drain cycle. If the
air actuator does not open the valve , check that the
control air supply is at least the minimum pressure
required.
2. If the valve opens, but the drain does not empty quickly,
no more than 20 seconds, ensure that there is system
pressure.
3. If still not emptying, check the downstream piping from
the drain valve to ensure there isn’t a closed valve or an
obstruction.
4. If the drain is still not draining, suggest contacting the
factory.
