PROCEDURE

Equipment Type:

WRO 300

Subject:

Updated Installation Procedure

From:

Richard Homol

A new installation procedure and checklist have been released for the WRO300.

Along with the procedure, the installation kit has also changed. The procedure and checklist are attached.

In the past, installation kits were shipped with a pressure regulator. The pressure regulator has been replaced with the Gambro flow regulator, WTW522001001

.

The flow regulator should be installed when the operating pressure is greater then 30 psi. It is not required at facilities where the operating pressure falls below

30 psi., but the device should be left with the customer for future use.

There have also been changes to the conductivity calibration, according to the new service manual, WTHCEN12073.

Other minor content changes have been made in anticipation of changes to the pretreatment components.

Please refer to Table 2, Tools List, to make sure you have all the necessary tools to perform the installation.

If you have any questions, please call Technical Support at 1-800-525-2623.

Procedure

1. Assemble Gambro Cart and Prefilter Kits

1.1. Assemble the cart and install the pretreatment kits according to the instructions provided.

NOTE: If an alternative non-Gambro pretreatment system is to be used, it is the

responsibility of the customer to make sure all local, state, and federal regulations are followed. Use the quick-connect fittings, provided in the Installation Kit to attach the pretreatment assembly to the WRO 300. Use the quick-connect, valve stem, on the hose coming from the pretreatment components. See figure 1

NOTE: If the SS Accessory Box is to be installed, perform all of the Pretreatment and

WRO 300 installation steps and mount the WRO 300 to the cart before attaching the SS

Box. It is difficult to remove the cover of the WRO 300 after the box is installed.

NOTE: The use of carbon tanks will necessitate the installation of particle filtration

between the tanks and the inlet of the WRO 300. A 10” 5 micron filter is recommended.

in the Installation Guide, HCEN12115, which is shipped with the WRO.

2.1. Carefully remove the WRO from the shipping container according to instructions found on the outside of the box and verify that all parts have shipped according to the chart found in section 1.1 of the Installation Guide.

2.2. Verify that all parts have shipped in the Installation Kit. See list above.

CAUTION! The WRO 300 contains a preservative which may cause irritation to eyes,

skin, etc. The internal sections of the machine may be under pressure due to altitude or atmospheric conditions. Use caution when removing the plugs to prevent contact with the preservative.

2.3. Remove the plugs from the back of the WRO using the tube removal tool

(K12215001) provided in the Installation Kit. See section 1.3 of the Installation

Guide.

Mounting the WRO 300

When mounting the WRO onto the Gambro cart make sure the WRO 300 is oriented in such a way that the back of the RO is on the same side of the cart as the cord handle. See

Figure 2.

WT300INST01 Rev. A Page 4 of 10

Figure 2

2.4. From underneath the cart base, use the four M6 bolts and lock washers to connect to the mounting holes in the bottom of the WRO 300.

2.5. Installation of Tubing and Product Loop

MAKE ALL TUBING CONNECTIONS USING THE HOSE CLAMPS

PROVIDED.

NOTE: Be certain to use the proper size clamps when attaching the tubing to the

WRO 300. The 6 ½ ft, ¼ in. ID tubing, 11mm hose clamps and smaller sized elbows are used for the product loop.

NOTE: Italized wording refer to specific steps found in the Installation Guide,

Section 1.3.2 Using the tubing provided, cut to appropriate length as described below.

2.5.1. Feed Water Inlet: Cut the feed line 3 ft long and attach a QC Body to one end of the hose, then connect it to the output connector of the pretreatment component.

WT300INST01 Rev. A Page 5 of 10

NOTE: Attach the QC Valve Stem to the outlet of the pretreatment line if

needed, then connect the hoses together.

2.5.2. Use an angled connector and clamp and attach the feed line to the back of the WRO 300 as shown in figure 1.5 of the Installation Guide

2.5.3. Product water outlet and return: Use the supplied 2 meter (6 1/2 ft) hose, cut it slightly off-center and attach the Y coupling.

2.5.4. Attach the 2 smaller angled connectors and attach to the WRO 300 as shown in figure 1.6 of the Installation Guide.

2.5.5. Drain Outlet: Cut the drain line in two parts. 1 part should be 1 ft long and attached to the WRO 300 using the angled connector.

Attach the QC Valve Stem to the opened end of the hose.

Cut the other part 8 ft. long.

Attach the QC Body to one end of the hose and connect the hoses together.

See figure 2 above.

2.5.6. Tank air vent: Use the 10 in. clear tubing supplied in the Installation Kit.

2.5.7. Incoming Water Line: Cut a section of hose 9 ft long and attach the hose adaptor. Connect the opened end of the hose to the input of the pretreatment system. Use the Quick Connect fittings if available. Connect the other end to a water source.

Note: The incoming water line may already be installed if the pretreatment was already assembled.

2.6. Install the power cord Be sure to run the cable underneath the handle.

2.7. Flush Carbon Pretreatment

2.7.1. Disconnect the QC connector from the drain line and attach it to the output of the first carbon component. Start with the Primary Carbon

Component, then do the Secondary Carbon Component if installed.

NOTE: If Gambro QC connectors have not been used on the pretreatment, it will

be necessary to flush the carbon components using what ever method that may be available.

NOTE: It is essential that the carbon be properly rinsed prior to starting the WRO

300. Carbon fines (carbon dust) present in new carbon filters and tanks can damage the RO membrane and pump if not properly rinsed out prior to use.

WT300INST01 Rev. A Page 6 of 10

2.7.2. Connect the water line to a water source and open the water valve partially to slowly purge the air from the pretreatment assembly.

2.7.3. Open the inlet water valve fully and allow the system to flush properly.

Black carbon fines will be observed at the drain. Allow carbon tanks to flush for 5 minutes after the drain line becomes clear. Carbon Filters should be flushed for an additional 2 minutes after the drain water is clear.

2.7.4. After flushing, turn off the water and proceed to the second carbon component or return the hoses to their original positions.

3. WRO 300 Rinse

3.1. Follow the instructions for rinsing the WRO 300 provided in section 1.5 of the

Installation Guide.

3.2. During Rinse observe the lowest pressure indicated on the pressure gauge located just before the RO. This is the Operating Pressure. Record this value on the checklist.

3.3. If the Operating Pressure is greater then 30 psi it is recommended to install the flow regulator. Operating pressures above 44 psi will require the installation of the flow regulator.

3.3.1. At the end of Rinse, close off the water supply and relieve the pressure in the pretreatment components.

3.3.2. Cut the tubing just below the back handle of the WRO and attach the flow regulator. See figure 2 above. (The arrow should point to the WRO 300.)
