1.0 STORAGE TANK COMPONENTS
THEORY OF OPERATION
The storage tank is equipped with 3 float switches, which will turn the
reverse osmosis unit off when the water reaches the predetermined
cutoff point and turn the RO on when the tank is drained to the
appropriate level float. The distribution pump on the storage tank will
cycle whenever there is a pressure drop detected. A third float
switch has been wired into the pump to act as a kill switch to prevent
the pump from operating when there is no water. (Applies to
models, 00HC-0091, 00HC-0093, 00HC-0095 and 00HC-0097)
The storage tank is equipped with 2 float switches, which will turn the
reverse osmosis unit off when the water reaches the predetermined
cutoff point and turn the RO on when the tank is drained to the
appropriate level float. The distribution pump on the storage tank will
cycle whenever there is a pressure drop detected. (Applies to
models, 00HC-0090, 00HC-0092 and 00HC-0094)

The Healthcare storage tanks come in three different sizes – 55
Gallon, 100 Gallon and 185 Gallon. Shown in this manual is the 185
Gallon model.

2. PUMP PRESSURE GAUGE: Gauge that measures the pressure in pounds
per square inch (PSI) when the distribution pump is running.
3. DISTRIBUTION PUMP: Pump that is used to distribute water to the system
whenever the internal pressure drops or there is greater than 3.0 GPM
flow.
4. SYSTEM OUTLET HOSE: Hose that is provided to change the system
outlet from FPT to MPT. See chart below for models and sizes

6. BYPASS QUICK CONNECT: Used to allow untreated water to completely
bypass the system in the event of downtime.
7. RETURN FROM LOOP: Connection that can be utilized to allow the loop to
re-circulate back into the storage tank to minimize opportunities for
bacteria growth. The return flow control on this is 3 GPM.

8. HIGH LEVEL FLOAT: Sends a signal to the RO when the tank is full
to stop water purification.
9. MID LEVEL FLOAT: Sends a signal to the RO when the
predetermined mid level has been breached to have the RO begin
water purification.
10. PUMP PROTECTION FLOAT: Prevents the pump from operating
when this switch is open.

2.0 INSTALLATION AND STARTUP
1. Locate the storage tank on a firm, level foundation. For seismic
requirements, drill (4) 5/8” diameter holes into the concrete through
the mounting holes in the storage tank feet a minimum of 4” deep.
Install (4) 5/8” diameter, HILTI KB-TZ Expansion anchors through
the 4 holes on the pads to anchor into the ground. A minimum of 4
threads for each anchor must be below the concrete prior to
application of 60 ft-lbs of torque.
2. Connect the discharge from the pump to the distribution piping.
3. Run the floatswitch quick disconnect to the RO and lock in place.
4. Prime the pump by filling the tank with water and opening the valve into to
the pump’s inlet. Loosen the priming plug on the pump to allow the air to
escape. Once water starts to escape, re-tighten the priming plug
(Only applicable to pump 80-0002).
5. Wire or plug the storage tank power cord into a dedicated UL listed
NEMA 4X rated disconnect. See table below for models and pump
voltages.

6. If the pressure delivered by the pump is to be changed, a technician will
need to have access to a smartphone with the Grundfos GO application
along with a Grundfos communication dongle (AMW PN 97-0003). Refer
to IFU 98-9057 to setup parameters to change pressure delivered by the
pump.
7. Loop should be flushed prior to operating the distribution pump on the
storage tank.

3.0 TANK DISINFECTION
Storage Tank Disinfection Procedure:
1. The storage tank can be disinfected using household bleach or a
peracetic acid disinfectant (PAA).
WARNING: Never allow Chlorine (bleach) to come into contact with PAA.
Doing so will cause a severe chemical reaction!
a. For a 55 gallon tank, fill to the RO shut-off level mark and add 1
quart of household bleach or PAA.
b. For a 100 gallon tank, fill to the RO shut-off level mark and add 2
quarts of household bleach or PAA.
c. For the 185 gallon tank, fill to the RO shut-off level mark and
add 4 quarts of household bleach or PAA.
NOTE: The values above will provide a 250 PPM concentration of
disinfectant. If desired, the disinfectant can be doubled to provide
a stronger kill (500 PPM). However, when this is done, the rinse-
up time will be significantly longer.
2. If your system is installed with a recirculation loop back to the
storage tank, recirculate the system for 30 minutes.
3. If your system is a demand feed (where the pump only operates
when your equipment calls for water), connect the bypass hose to
the quick disconnect and place the other end of the bypass hose
into the storage tank, recirculate for 30 minutes.
4. After recirculation, drain the tank, fill with RO water, and recirculate
for 5 minutes.
5. Drain, then refill the tank, and recirculate for 5 minutes. Use a
chlorine test strip to verify the residual chlorine level or a PAA test
strip to verify the residual PAA level.
6. Repeat step 4 and 5 until the test strip indicates a residual level at
or below 1.0 ppm.
