CAUTION Unusuts noise or vibration indicates a
problem. DO not continue to Operate unUI
you Identify and correct the source of the
problem.
NOTE Ensure the direction of rotation Is correct
per the arrow on the motor. If the rotation
Is incorrect on three-phase units,
interchange any two of the three leads. COMPRESSOR CONTROLS
AUTOMATIC START & STOP CONTROL. This tYpe of
control applies to electric motor ddvan modets under

NOTE Automwits Start & Stop Control is
intended for usa when the motor will start
no more than 6 tlmes per hou_
_en the receiver tank pressu_-e reaches the fair/preset

sta ps the u nit. When the receiver tank pres_ re dlops below
the factory _'e-set minimum (usually 135 PSIG), the pressure

DUAL CONTROL This type of control applies to etectnc
motor units over I 0 horsepowen Sei_.t either automaUc start

NOTE The auxiliary valve is thc_ry pre-set at

switch setting.
CAUTION Running unloaded for more than
20 minutes per hour or more than
15 minutes continually with the use of
constant speed control will cause oll

WARNING High voltage Is present at the pressure
switch contacts when the power supply is
connected. Disconnect, lock and tag main
power supply before making adjustments.
CAUTION DO not adjust the pressure switch to
exceed the maximum discharge pressure
of the unit.
NOTE Adjust the pressure swltob only If

CUT-IN & CUT-OUT. The cut-out (compressor shut-down) is
the pressure at which the swit_-h contacts open, and the c,_in
(compressor restart) is the pressure at whi_l the switch
contacts dose. See COMPRESSOR CONTROLS.
ADJUSTMENT CONTROLS.A_I pressure switches have a
range adjustment control (A). Some pressure switches also
have a differential adjustment (B) control On switches with nu_ a
differential adjustment control, the span between cut_n and cut-
out pressure levels switches is factory set for 40 ± 4 PSIG and
cannot be adjusted.
NOTE Some pressure switches are equipped
with an on-off lever used to open and close
the electrical contacts Inside the swif_h.
THIS LEVER IS NOT A DIFFERENTIAL
ADJUSTMENT CONTROL. The pressure
sw_che_ with the on-off lever do not have
a differential adjustment control.
ADJUSTMENT PROCEDURES (SWITCHES WITHOUT
DIFFERENTIAL ADJUSTMENT CONTROL):
1. Remove the p_ssure switch cove_
2. Adjust the range by turning the range adjustment s_rew
clockwise (in) to increase the cut-c,JI point or Coun_e_
clockwise (cut) to decrease the cu_ut point.
NOTE: One full turn changes the switlng
approximately 2 PSIG.
3. Replace cove_ reconnect power supply and start the
compresson
4. Note the pre_ure gauge reading at which the compressor
