INSTALLATION − SECTION B
Review all SAFETY information in Section A.
Since pump installations are seldom identical, this
section is intended only to summarize recom-
mended installation practices for the pump and
control box. If there are any questions concerning
your specific application, contact your Gorman-
Rupp distributor or the Gorman-Rupp Company
All functions performed by the customer on the
pump or control must be done in accordance with
MSHA schedule 2G regulations to ensure the ex-
plosion-proof integrity. No alterations of original
design may be made without the consent of the
Gorman-Rupp Company and MSHA.
To retain permissibility" of this equipment,
the following conditions shall be satisfied:
1. GENERAL SAFETY. Frequent inspec-
tion shall be made. All electrical parts,
including the portable cable and wiring,
shall be kept in a safe condition. There
shall be no openings into the casings of
the electrical parts. A permissible distri-
bution box shall be used for connection
to the power circuit unless connection is
made in fresh intake air. The machine
frame shall be effectively grounded. The
power wires shall not be used for
grounding. The incoming voltage must
match the voltage rating of the motor.
2. SERVICING. Explosion-proof enclo-
sures shall be restored to the state of
original safety with respect to all flame
arresting paths, lead entrances, etc.,
following disassembly for repair or re-
building, whether by the owner or an in-
dependent shop.
3. FASTENING. All bolts, nuts, screws,
and other means of fastening, and also
threaded covers, shall be in place, prop-
erly tightened and secured.
4. RENEWALS AND REPAIRS. Inspec-
tions, repairs, or renewals of electrical
parts shall not be made unless the por-
table cable is disconnected from the cir-
cuit furnishing power, and the cable
shall not be connected again until all
parts are properly reassembled. Spe-
cial care shall be taken in making renew-
als or repairs. Leave no parts off. Use re-
placement parts exactly like those fur-
nished by the manufacturer. When any
lead entrance is disturbed, the original
leads or exact duplicates thereof shall
be used and stuffing boxes shall be re-
packed in the approved manner.
5. CABLE REQUIREMENTS. A flame-re-
sistant portable cable bearing a MSHA
assigned identification number, ade-
quately protected by an automatic cir-
cuit-interrupting device, shall be used.
Special care shall be taken in handling
the cable to guard against mechanical
injury and wear. Splices in portable
cables shall be made in a workmanlike
manner, mechanically strong, and well
insulated. One temporary splice may be
made in any trailing cable. Such trailing
cable may only be used for the next
24-hour period. No temporary splice
shall be made in a trailing cable within
25 feet of the machine, except cable reel
equipment. Connections and wiring to
the outby end of the cable shall be in ac-
cordance with recognized standards of
safety.
