IMPORTANT INSTALLATION INSTRUCTIONS
FOR DIAL-AIR™ REGULATORS
1. DO NOT install the unit until you have read
this entire product information sheet.
2. EXCEPT
manufacturer, this product is specifically
designed for compressed air service, and use
with any other fluid (liquid or gas) is a
misapplication. For example, use with or
injection of certain hazardous liquids or gases
in the system (such as alcohol or liquid
petroleum gas) could be harmful to unit or
result in a combustible condition or hazardous
external leakage. Manufacturer's warranties
are void in the event of misapplication and
by
manufacturer assumes no responsibility for
any resulting loss. Maximum pressure rating
is 300 psig (21 bar). Temperature range is
32°F to 150°F (0°C to 65.5°C).
3. INSTALL upstream of and as close as
possible to where regulated air is needed.
4. INSTALL with air flow in direction of arrow on
casting.
5. DO NOT restrict the air flow with undersize
your local piping or fittings, unless maximum air flow is
not needed.
6. INSTALL regulator in any rotational position.
7. GAUGE PORTS may be used for installing
!
gauge or they may be used as additional
regulated air outlet ports. Plug all unused ports.
8. PANEL MOUNTING requires a 2 11/16" (69
mm) diameter hole, and 4 7/32" (5.5 mm)
screw holes. Unit can be mounted on material
up to 1 1/4" (32 mm) thick.
!
9. INSTALLATION of a 5-micron rated filter
upstream of regulator is recommended.
10. TO REGULATE AIR turn adjustment knob
clockwise to raise the regulated air pressure
and counterclockwise to lower the regulated
air pressure.
IMPORTANT MAINTENANCE INSTRUCTIONS
FOR DIAL-AIR™ REGULATORS
1. BEFORE SERVICING THIS UNIT, READ
THIS ENTIRE PRODUCT INFORMATION
SHEET AND TURN OFF AIR SUPPLY AND
VENT BOTH SIDES OF REGULATOR.
LUBRICATION OF DIAL-AIR™ REGULATORS
1. FOR TROUBLE-FREE OPERATION, proper
lubrication of the Dial-Air™ regulator is
essential.
2. WHEN ANY of the following symptoms occur,
lubricate regulator with Magnalube-G
note) If Magnalube-G
heavy grease such as Parker O-ring Lube,
Lubriplate, or Molykote, however, these
lubricants "wash out" much sooner than
Magnalube-G
lubricant.
YOUR LOCAL A. Excessive relief venting.
B. Inability
pressure.
C. Erratic secondary pressures.
as otherwise specified by

Dial-Air™ Regulators
D. Excessive hysteresis (a retardation of
desired effect: in this case because of the
lack of lubrication).
3. Refer to "Figure A" for steps 1 thru 10.
1. Remove bottom plug (1), main valve
spring (2), main valve (3), pilot valve
spring (4), and pilot valve (5).
2. Clean main valve molded rubber seat (Do
not lubricate).
3. Clean and lubricate bottom plug seal,
main valve seal and pilot valve seal.
4. Reassemble unit.
5. If problem is not remedied, lubricate
remaining seals. (See steps 6 thru 10)
6. Remove retaining ring (6) and pull bonnet
assembly (7) from unit.
7. Remove upper piston (8), upper piston
cup (9), lower piston (10), needle valve
(11), and needle valve spring (12).
8. Clean and lightly lubricate inside of body.
9. Clean and lubricate upper piston seal,
upper piston cup seal, lower piston seal,
needle valve seal and main valve slide
seal (13).
10. Reassemble unit. If symptoms still exist,
contact manufacturer.
RECALIBRATION OF DIAL-AIR™
REGULATORS
1. DO NOT ATTEMPT TO CALIBRATE UNIT
UNTIL ALL EIGHT SEALS HAVE BEEN
PROPERLY LUBRICATED.
2. TO RECALIBRATE Dial-Air™ REGULATOR:
A. INSTALL regulator on air line with at least
110 psig (7,5 bar) air pressure at the inlet
port.
B. INSTALL an air pressure gauge to one of
the gauge ports. Plug remaining gauge
port with plug (supplied).
C. REMOVE lock button (Figure A, Item 14)
from unit.
D. TURN adjusting knob to 100 psi (7 bar)
setting.
E. CHECK the gauge for 100 psig (7 bar)
reading. If gauge reads other than 100
psig (7 bar) adjust screw "A" (Fig. B) with a
screwdriver while holding adjusting knob
on 100 psi (7 bar) setting. If more than
one-half turn of screw "A" is required to
achieve 100 psig (7 bar), see "G" below.
F. TO CHECK CALIBRATION ADJUSTMENT:
when dial and gauge are reading the
same (100 psig ± 2 psig; 7 bar ± 0,14
bar), turn adjusting knob to 20 psi (1,4
bar). Unit is calibrated when gauge reads
20 psig ± 5 psig (1,4 bar ± 0,34). (The ± 2
psig and ± 5 psig are accepted tolerances
of the most commonly used gauges.)
G. DO NOT adjust screw "A" more than one-
half turn when calibrating unit. If unit has
been properly lubricated and more than
one-half turn is required to calibrate it,
additional problems with unit are involved
and unit should be returned to the vendor.
