CONTROLLER
The Hydroid microprocessor controller includes
numerous standard features such as pressure switch
controls, TDS/conductivity monitor, pre-treatment lock
out, float switch controls, and flush valve control. The
controller displays system status, fault sensors, and
input TDS status on an easy-to-read 3-digit LED display.
PRE-FILTRATION
Hydroid systems come standard with a carbon pre-filter.
Change the pre-filter when 75,000 gallons of purified
water has been produced. Or, a 15 or more psi drop
occurs on feed gauge, when compared to the initial
startup reading. For example, if the FEED Pressure
Gauge reads 60 psi (you will need to log initial pressure
after step 10 on page 15 has been performed) the pre-
filter should be changed when the FEED Pressure
Gauge is 45 psi or below.
BE SURE TO LOG ALL DATA UPON STARTUP (PG 25)
THE SYSTEM MUST BE OPERATED ON PRE-FILTERED WATER ONLY
FEED PRESSURE GAUGE
This gauge measures the water pressure when it exits the pre-filter.
LOW PRESSURE SWITCH
The low pressure switch shuts off the system when the FEED water pressure drops below 15
psi, preventing damage to the pump. The system restarts automatically when there is a
constant pressure of 40 psi or more.
IF THE SYSTEM PRESSURE IS FLUCTUATING, AND THE SYSTEM CYCLES
OFF AND ON, TURN THE SYSTEM OFF AND ENSURE THAT PROPER FEED
WATER FLOW AND PRESSURE ARE BEING SUPPLIED TO THE SYSTEM.
