11. Determine location on the operator
panel for the air bleeder valve and cut
holes in the panel according to the
dimensions shown in figure 7D.
12. Install panel placard with valve
attached and secure in place using the
¼-20 UNC X 1 inch long cap screws and
¼-20 UNC nuts provided.
WARNING: Use tubing rated at the
maximum discharge pressure of the fire
pump, 500 PSI (34 BAR) minimum.
13. Connect a length of 3 /
8
inch O.D. tubing
from the fitting on the Hale MIV valve
body to the fitting on the inlet of the air
bleeder valve.
14. Connect a length of 3 /
8
inch O.D. tubing
from the outlet of the elbow on the
outlet of the air bleeder valve and route
this tubing away from the operator
position. Make sure the outlet of this
tube is visible to the pump operator.
F. SUCTION HOSE PRIMING
NOTE: If suction hose priming
connection is not used, remove plastic
shipping plug and replace with ¾ inch
NPT pipe plug.
NOTE: Coat all fitting threads with a
suitable sealant before connections are
made.
1. Remove plastic plug from ¾ inch NPT
outboard priming tap located next to
relief valve.
2. Install a priming hose connection fitting
into ¾ inch NPT tapped hole
3. Using hose rated at 26 in. (760 mm) Hg
and 500 PSI (34 BAR) pressure, connect
the outboard priming tap to Priming
pump. Continue installation of priming
pump in accordance with procedures
provided with priming pump.
Dependent on configuration either an
additional priming pump is installed or a
three way valve is installed to control
priming.
G. PANEL PLACARDS, HANDWHEEL
AND HANDWHEEL EXTENSION
1. Locate and install the panel placard(s)
on the pump operator panel. Mounting
dimensions are provided in figure 7 to
assist in making cutouts for placard
mounting.
CAUTION: Electric motor and wiring are
protected by a circuit breaker. DO NOT
remove or bypass the circuit breaker as
severe damage to the electric motor or
apparatus wiring could result during a
motor stall condition.
WARNING: Any electrical system has the
potential to cause sparks during
installation, service or repair. Take care
to eliminate explosive or hazardous
environments during installation, service
or repair.
CAUTION: The Hale MIV is designed for
operation on 12 Volt DC negative
ground electrical systems only.
NOTE: The electric panel placard wiring
harness is 96 inches (2438 mm) long. If
the panel layout requires extra wire
length a jumper (Hale P/N 513-0270-06-
0) is available or one may be fabricated
using minimum 14 AWG chemical
resistant wire with Packard WeatherPack
connectors. Care should be taken to
make sure the color code is maintained
per the original wiring. Wiring diagrams
are provided in the troubleshooting
section of this manual.
CAUTION: Follow NFPA requirements for
apparatus electrical wiring. Use
minimum 14 AWG, type SXL or GXL (SAE
J1128) wire. The wiring shall be
protected using 289
o F (143 C) minimum
flame retardant, moisture resistant loom
or braid.
