Accelerator Option
FM-086G-0-45B
Resetting the Accelerator device:
Make sure the system is properly drained and reset.
Observe the air pressure gauge (3) on top of the
accelerator. The gauge must read zero before the
accelerator will automatically reset. It may be necessary to
loosen, remove and re-install the accelerator air gauge
(use the appropriate wrench) to vent trapped air pressure
from the upper chamber, even when the gauge indicates
zero if the air supply is on while performing the reset.
Make sure system is pressurized according to
recommended settings. Do not exceed 60 Psi (414 kPa).
INSPECTION & TESTS:
After every operation, and each time water is allowed to
enter the system:
1. Inspect the interior of the accelerator for the presence
of water. Dampness or condensation may indicate
that the air supply is not being dried adequately. If
water is allowed to enter the middle or upper chamber
of the accelerator, it may contaminate the accelerator
orifices and prevent it from operating properly.
2. Remove the 1/2" NPT plug from the base of the
accelerator. If water or dampness is present, the
accelerator must be disassembled, cleaned and dried.
For more information about this procedure, refer to
Viking datasheet 122 (Form No. 071692).
3. Weekly inspection is recommended unless system is
provided with low air alarm, then monthly inspection
may be adequate.
4. Check the air pressure gauge (3) at the top of the
accelerator. Air pressure in the upper chamber of the
accelerator should be equal to the air pressure
maintained in the system on which it is installed.
Note: Standard tolerance allowance in pressure gauge
calibration may result in a slight variation when pressure
readings of any two gauges are compared.
A difference in pressure other then slight variation due to
gauge calibration may indicate gauge malfunction, plugged
accelerator orifices and/or filters, or other maintenance is
required. See Viking datasheet 122 (Form No. 071692),
paragraph. 12 ACCELERATOR MAINTENANCE.
5. Verify that all other trim valves are in their normal
operating position.
6. Check for signs of mechanical damage and/or
corrosive activity. If detected, perform maintenance
as required or, if necessary, replace device.
7. Verify that the water supply main control valve is open
and secure and that the by-pass valve (1) is open.
