2. The compressor will run HOT. Although the compressor pump includes an
internal thermal disconnect switch which will automatically shut the unit off if it
becomes too hot, as much ventilation as possible is advised. Do not install the
pump in a very small enclosed space.
3. We recommend that the tank be bulkhead mounted with the ¼" N.P.T. Drain
Cock facing down and accessible. Once a year, switch the PT148-005 Pressure
Switch on the compressor to OFF, and open the drain cock on the tank to drain
condensation from the tank, if any. Experience will dictate if the tank should be
drained more or less often. IF ANY PRESSURE IS LEFT IN THE SYSTEM,
BLEED IT OFF SLOWLY BEFORE OPENING DRAIN COCK
COMPLETELY.
4. Wiring connections are made within the PT148-005 Pressure Switch which is pre-
wired to the compressor pump. Simply connect your your positive line voltage to
the RED line connection marked "Line", and ground to "Line" matching the
BLACK compressor wire. (

Units, the electrical circuit should include a slow burn fuse or breaker rated for
20 amps. For 12 Volt Units, a 25 amp slow burn fuse or breaker should be used.
Refer to the installation drawing included with these instructions for additional
information. We recommend placing a single pole toggle switch in either of these
lines if not connected to a breaker panel, to disconnect the compressor when not
needed during storage periods etc.
5. The pressure switch mounted on the compressor will automatically switch on the
compressor when the pressure in the system is below 120 P.S.I. and turn
compressor off when pressure reaches 150 P.S.I. MAKE SURE THE SWITCH
ON THE SIDE OF THE PRESSURE SWITCH IS SET TO "AUTO".
Upon initial installation of this system, verify that the compressor

pumps strongly to a pressure between 140-150 p.s.i. and shuts off.
You should here an audible "click" when the pressure switch
trips. The time to pump the system from 0 p.s.i. to 150 p.s.i.
should not exceed 8 minutes. If the pumping time exceeds 8
minutes and the system does not reach full pressure, immediately
disconnect power to the unit and see the troubleshooting list
below.
7. Please note that the P553-01 Air Regulator should be set to 100 p.s.i. for
maximum blast duration at the horn.
