OPERATION
Ambient conditions - All air pumps should be operated in a well
centilated area where the surrounding air is relatively clean, dry and
temperatures are consistently within the range of 35°F and 100°F.
WARNING
To avoid re or explosion, do notoperate this product in areas with
ammable gases, vapors or explosive dust in the air. Flammable gases
or vapors include but not limited to; lighter uid, solvent type cleaners,
oil -base paints, gasoline, alcohol or aerosol sprays. Explosive dusts
inclued but not limited to; coal, magnesium, grain or gun powder.
ELECTRICAL
Operation of all linear air pumps require connection to a source of
electric power. On models supplied with a factory mounted cord and
plug assembly, the three prong plug can simply be inserted into a
standard 115 volt wall outlet to make the pump operate (see grounding
instructions). For models supplied with bare wire leads, a qualied
electrician should be contracted to install the pump.
These linear air pumps are electrically thermal protected using a “single
trip”, Non-replaceable type protector. If the pump fails to operate
after initial start-up, the protector may have tripped indicating a high
temperature condition existed. Once these “single trip” type protectors
have tripped the pump is no longer usable and must be replaced.
MAINTENANCE
Periodic maintenance is required on all linear pressure pumps. (Models
2420, 2430, 2440, 2460, & 2478). Diaphragm and head assemblies for
theses models should be replaced after every 24 months of operation.
