CONCENTRATE (WASTE WATER) CONNECTION
Locate the 1" or 3/4" connection (Depending on the unit) labeled concentrate and attach to a drain. Run
the concentrate line to an open drain in a free and unrestricted manner (no backpressure). It is advised
that an air-break be used on the concentrate line to prevent siphoning of water from the pressure vessels
when the system is in standby.
CAUTION: ANY RESTRICTIONS OR BLOCKAGE IN THE DRAIN LINE CAN CAUSE
BACKPRESSURE, WHICH WILL INCREASE THE SYSTEM'S OPERATING PRESSURE. THIS CAN
RESULT IN DAMAGE TO THE SYSTEM'S MEMBRANES AND COMPONENTS.
ELECTRICAL
The motor used on the HRO 6-Series systems are pump and motor combination. The motor is available
in 220/460 Volt, 50/60 Hertz, 1 Phase/3 phase. Each HRO 6-Series system is equipped with a 5 foot
electrical cord.
Ensure that the electrical circuit supplying the system is compatible with the requirements of the specific
HRO 6 model you are installing.
NOTE: IT'S RECOMMENDED THAT A LICENSED ELECTRICIAN WIRE YOUR SYSTEM IN
ACCORDANCE WITH LOCAL AND NATIONAL ELECTRICAL CODES (NEC).
WARNING: TO REDUCE THE RISK OF ELECTRICAL SHOCK, THE INCOMING POWER
SUPPLY MUST INCLUDE A PROTECTIVE EARTH GROUND.
HRO 6-Series systems are typically controlled with a liquid level switch in a storage tank. The liquid level
switch turns the system on when the water level in the tank drops, and off when the tank is full. Liquid
level switches can be obtained by your local dealer or distributor. If a liquid level switch is to be used,
install it at this time.
PRE-FILTRATION
HRO 6-Series systems are supplied with a 5 micron sediment filter. Change the cartridge once a month or
when a 10-15 psi differential exists between the two pre-filter gauges. Ask your local dealer or distributor
about Pre-Filtration systems, if required.
NOTE: THE SYSTEM MUST BE OPERATED USING FILTERED FEED WATER ONLY.
PUMP
The pump used on the HRO 6-Series systems is of the multi-stage centrifugal stainless steel type.
Follow these guidelines to ensure proper operation of the pump:
The pump must NEVER be run dry. Operating the pump without sufficient feed water will damage
the pump.
