Quincy QTS Series Instruction Manual page 9

Noise
Federal and local laws govern acceptable noise lev-
els; should a question about noise levels arise, check
with local officials for specifications.
CAUTION !
Unusual noise or vibration indicates a problem. Do
not operate the compressor until the source has
been identified and corrected by a qualified techni-
cian.
Electrical Information
The installation, electric motor, wiring, and all elec-
trical controls must be in accordance with NFPA
National Electric Code, National Electric Safety Code,
state and local codes. Failure to abide by the national,
state and local codes may result in physical harm
and/or property damage. Note: This unit must be
grounded.
Portable Industrial & Air Master Series compres-
sors are equipped with an electrical supply cord. Do
not modify the cord! If the plug will not fit the outlet,
have the correct outlet installed by a certified electri-
cian.
Stationary Industrial & Air Master Series (2 & 4
cylinder) compressors, not equipped with a power
cord, must be wired in accordance with the NEC and
all state and local codes and ordinances. (See Figs. 1
through 8 for Wiring Schematics.) .
DANGER !
High voltage may cause personal injury or death.
Disconnect and lockout/tagout per OSHA regula-
tion 1910.147 all electrical power supplies before
opening the electrical enclosure or servicing.
WARNING !
Never assume a compressor is safe to work on just
because it is not operating. It could restart at any
time. Follow all safety precautions outlined in MAIN-
TENANCE.
Overload Relay Protection
(if so equipped)
An overload relay will stop the unit if the motor
becomes overheated. (Causes for overheating of the
motor can be found in TROUBLESHOOTING.) Once
the overload relay has been tripped, the motor must
cool and the red overload button on the motor must
be reset before the unit will start.
Industrial Series
50263-106, October 2004
CAUTION !
Overload relays are designed to protect the motor
from damage due to motor overload. If the overload
relay trips persistently, DO NOT CONTINUE TO PUSH
THE RESET BUTTON! Contact your local Quincy
distributor for assistance.
Extension Cords (portable units)
To avoid power loss and overheating of the motor, use
of additional air hose is recommended rather than an
extension cord. If an extension cord is to be used, it
must be a 3 wire cord with a 3 prong plug. Refer to the
following chart to determine the wire gauge required
in relation to the cord length:
Cord Length
up to 25 ft.
up to 100 ft.
CAUTION !
QTS compressors should not be operated more
than 10° off level.
Mounting Stationary Units
Proper mounting of Quincy compressor units is cru-
cial to the safe operation and longevity of the equip-
ment. The installation requires a flat and level con-
crete floor or pad (for mobile units see Mounting
Mobile Units). Satisfactory results can usually be
obtained by mounting the compressor unit on vibra-
tion isolating pads (see Fig.9) available from your
local Quincy distributor. All vertical tank units
must be anchored!
