INSTALLATION
HT2000/MAX200 Water Muffler Instruction Manual
Position and Connect the Pump to the Water Table
1. Place the pump near the Water Table feed port to be used. The pump
must
be
below the Water Table Water level in order to properly function.
Note: It is important to place the pump as close as possible to the Water
Table. Longer distances can result in pump priming and water lag
problems during startup, resulting in excessive noise and smoke during
initial starting.
2. Install the suction filter/strainer (#027009) to the Water Table feed port. Figure
2-2 represents an optional installation; the user may wish to use another configu-
ration. The reducer bushing (#015578) and nipple (#015509) are supplied; other
required filter/strainer connection and support hardware are customer- supplied.
3. Connect the pump inlet to the filter/strainer assembly using the supplied four-foot
hose assembly (#024023). (See Figure 2-3.) If more than four feet of hose is
required, use solid tubing (eight feet maximum). If solid tubing is not used in
installations of over four feet, the hose could collapse due to the initial suction of
the pump at turn on. If solid tubing is to be installed,
do not use PTFE tape
.
Use liquid pipe sealant only.
Connect the Pump to the Nozzle Assembly
Route the pump discharge hose assembly (# 024022) from the pump to the
nozzle assembly through the power track or festoon system. In no case should
the discharge hose be longer than 80 feet (24.4 m). The elbow on the nozzle
can swivel for easy access. Tighten with set screw (see Figure 2-1).
Note: If the discharge hose is routed in an overhead festoon system, a check
valve may be required. To determine if a check valve is needed, refer to
the
Pump Discharge Hose Water Recovery Checkout at the back of this
section.
Connect the Pump to the HT2000
1. Make all electrical connections as detailed in Figure 2-3. The pump should be
electrically installed by an experienced electrician in compliance with the
specifications of national or international electrical codes. The motor is provided
with overload protection.
WARNING
Turn all power to the HT2000 or MAX200 OFF before connecting pump to power supply!
