allow the system to drain completely 2~3 times before the unit is left with the customer. This will help to ensure that any odorous tastes left in the system lines, etc. are removed.

underneath the label “DRaIN”, you will find a button that should be in the Off position. Turn this switch On and the entire system will drain out the open flush valve.

In order to properly install a unit at the customer site, the system will have to be flushed an additional two-three times to ensure customer satisfaction. This can take place either at the dealer location or on site with the customer.

Locate drain device (as shown below). Lift Cold lever up and immediately attach the device, latching the hook to ensure stability in draining. Repeat with the Hot lever for all units. ensure there is a proper place to drain the water into.

Check for Leaks /Hose Connections 2

Booster PumpMake sure to check the connections to and from the booster pump. They could have loosened duting transit.

Under sink connectionsTighten all connections with your hands and ensure proper stability. Then check for leaks by turning on the water. Continue to tighten as necessary to con-trol any leaking. To prevent leaks, tighten the filters before installation with a filter wrench.

When checking for leaks, please adhere to the following checklist:

1) Booster Pump 2) Under sink connections

3) All tubing running to unit 4) In line (Direct) connections

5) 3/8” drain 6) Filters

7) WLD Sensor

3/8” Watera leak can occur due to the 3/8” drain line water for a few different reasons:

1) Connection from the drip pan is not secured or isnot draining properly.2) Water from the melted Ice is not draining properly

BASIC POU INSTALLATION


Install product on a level surface. For uneven surfacees, level the product byadjusting the legs of the unit.Iguassu Ice: Use level found in trip tray for reference.

temporarily remove the connector part as provided from your given water source. Then, connect the main water line adaptor.If the sealing O-ring at the connection piece is removed or damaged, it can lead to leakage.

Connect tubing hose into water source adaptor and then attach the water inlet on the rear side of the product.

If drainage does not function properly due to improper installation, then water may flow back toward waterspout and cause an overflow.

Open the angle stop valve supplied into each household, and place the water source adaptor to the open position.

Check to see if water is leaking at each connection part.(Refer to previous section)

For stabilization of the cooling system and for safe use of this product, insert the power plug into an AC 110V/60Hz, 220/50z, 240V/50Hz, and 220V/60Hz power outlet 30 minutes after installing of the product.

Check whether water is supplied into the Ambient tank and whether there is any leakage in or around the tubing connections.(Refer to previous section)

Check whether water is coming out by pressing the water dispensing button 1 hour after

Ensure that the drip pan is draining properly.Pour water into the trip tray. (See Below).

Surrounding Temperatures

Water PressureWater pressure should read between 50-80 PSI. This is the ideal measurement for proper water

When installing systems, avoid locations with direct exposure to excessive heat, �ames, and/or locations a�ectedby humidity, direct sunlight, rain or snow.

when pressure reads greater than 80 PSI.

Total Dissolved SolidsWater quality is of utmost importance when dealing with a Reverse Osmosis system. In order to

greater than 500-600 TDS may cause a problem..

System TransportDo not tilt the system more than 45 degrees when moving. Excessive tilting may cause cooling malfunction.

System PlacementAllow 18 inches of space between system and wall for proper ventilation.

InstallationDo not bend tubing when connecting system to water source or place heavy objects on the tubing.This may restrict su�cient water �ow and reduce water puri�cation.

Installation IIMake sure that all tubing (inlet, brine and drainage) are securely connected to their �ttings on theback of the system to prevent water leaks. Water leaks may cause electric shock and/ or �re.

Before connecting a new Pre-Carbon �lter, you must �rst purge the �lter, e�ectively removing excess carbon from the inner casing. Before purging the �lter, make sure to tapup and down the �lter from all sides. This will allow carbon particles to loosen so that maybe expelled from the system via the purge process.

Temporarily remove the red clip and blue tubing (see below) to make way for purge tool’saddtional hose.

For this step, you will utilize the purge attachment as is mentioned in the necessary parts list.
