INSTALLATION
HT2000/MAX200 Water Muffler Instruction Manual
Connect the Pump to the MAX200
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.
2. Connect the water pump contactor to the MAX200 power supply with customer-
supplied three-conductor cable (see Figure 2-3).
3. Route the cable through the feed-thru located on rear panel of the power supply.
4. If using the MAX200/RHF power supply, connect the cable to TB4-302 (AC Hot),
TB4 -303 (Neutral), and shield. If using a standard MAX200 power supply,
connect the cable to TB4-89 (AC Hot) and TB3-79. Also connect a jumper
between TB4-88 (Neutral) and TB3-78.
Test the System
With all power and water connections complete, test the Water Muffler System:
1. Apply primary power to the HT2000 or MAX200 power supply.
2. Be sure that the Water Table water level is high enough to feed the pump (covers
the filter intake completely).
3. Check the Water Muffler pump for a proper direction of rotation. To do this,
proceed as follows:
Caution: Operating the pump in reverse rotation may cause extensive
damage.
• Depress the green POWER ON switch to turn on the HT2000 or MAX200.
• Depress the plasma start switch. As soon as the pump energizes, depress
the red POWER OFF switch.
• Look for a clockwise pump rotation as viewed from the top of the motor. A
direction of rotation arrow is also shown on the side of the pump casing. If
the pump rotates in a counter clockwise direction, reverse any two of the 3-
phase power leads to the motor.
4. Once the pump rotation is verified correct, energize the pump by depressing the
plasma start switch.
• If the water does not start flowing within 10 to 15 seconds, deenergize the
pump.
