Safety Precautions
Power sources, protective devices, and grounding provi-
sions must be in accordance with wiring instructions
provided in this manual.
Blower becomes hot during operation and may cause
burns if touched.
Do not operate the blower under load conditions which
exceed the rated full-load amps on the nameplate.
Do not install the blower in any area which may have an
explosive atmosphere or which may contain flammable
gases or liquids. Always provide proper ventilation. Do
not install in any area which may subject the blower to
corrosive liquids. Excessive moisture may cause electri-
cal failure; install the blower in areas free from water or
rain. Do not operate blower without motor cooling fan
cover, or without impeller end cover.
Before installing blowers with explosion-proof motors,
the buyer must check federal, state and local codes to
see if such motors are appropriate for the intended appli-
cation environment. It is the buyer's responsibility to
determine the suitability of any product for a particular
purpose.
Storage
If machine is to be stored for an extended period of time,
it must be carefully protected from dampness and dirt.
II. Installation
Locating, Mounting, Connecting
Ambient temperature at the installed location should not
be less than -5˚ F or greater than 104˚ F. Relative humidity
should not exceed 80%.
Mount the blower in a horizontal or vertical position as
shown in Figure 1; VB-055, VB-075 and VB-110 models
must be mounted only in a horizontal position.
Remove protective coverings, such as vinyl tape or
plastic plugs, from the inlet and outlet ports. For
models VB-004 and larger, attach to system piping
using threaded connection as provided. Avoid exces-
sive stress caused by pipe connector tightening or by
misaligned pipe on the inlet and outlet ports. Support
piping by brackets or other means. Models VB-001, VB-002
and VB-003 are supplied with a patented (U.S. Patent
5,791,870) reversible flange with threaded pipe or tubing
connections.
