How to install Huadi water purifier RO-21C8

2.3 Installation

2.3.1 Screw down the faucet after confirming that the inlet water source is turned off.

2.3.2 Wrap the stop-drain tape around 10 turns on the thread of the inlet plating ball valve, and lock the inlet plating ball valve into the inlet tee that is the inlet tee set.

2.3.3 Wrap the drain tape around the water tee, lock it into the screwed down faucet connection, and then connect the faucet back. (Please note that the water tee is connected to the cold water pipe, not the hot water pipe)

2.3.4 Drilling - You must drill three holes on the countertop to allow for power and water to enter and exit the machine, and for the installation of the gooseneck (these holes are not required if you are not installing under the countertop).

Hole 1: Gooseneck faucet mounting holes - Please select the location where the gooseneck faucet is to be mounted, generally 0.5 centimeters from the left to right of the sink on the countertop, so that the gooseneck faucet can rotate left and right to take care of both the inside and the outside of the sink, for ease of use (see picture on the right). Before drilling, please make sure that there is no support column underneath the sink, if necessary, please let the support column to find another location, because there is a support column because the thread under the gooseneck faucet is not long enough to be installed. After drilling, please use sandpaper or file to grind.

. Confirmation of hole size - hole 1 ~ 11m / m or 1/2 inch

Hole 2: water inlet into the hole: below the faucet in the direction of the water inlet tee group to drill a small hole for water intake.

. Confirm hole size - hole 2 to 6.5m/m or 1/4 inch

Hole 3: Power entry hole - for power entry under the flow-through, if there is already power under the flow-through, then there is no need to drill this hole

. Confirm the hole diameter - hole 3 ~ 6.5m / m or 1/4 inch

2.3.5 Installation of the gooseneck - according to the diagram, the gooseneck faucet will be locked on the flow of the table on the position of the hole 1. (Please note that the order of the gooseneck kit); installation is complete, the gooseneck plate up and down the trigger, the faucet left and right to confirm that the installation of a solid, will not be loosened.

2.3.6 Wastewater discharge - choose the location of wastewater, wastewater can be recycled and used for flushing the toilet or other purposes can also be discharged directly into the drain, if installed under the sink it is recommended to discharge directly in order to avoid the trouble; please drill a 1/4 inch or 6.5m/m holes for wastewater discharge on the drain under your sink.

2.3.7 Pressure Tank - Lock the pressure tank on top of the pressure tank, align the outlet of the pressure tank with the notch of the pressure tank, and place the pressure tank underneath the counter or wherever you want to place it. Turn the pressure pail on/off valve to the OFF position. (See Figure . Parallel to the outlet is open, perpendicular is closed)

2.4 Connection

2.4.1 Basic PE water pipe connection method - PE water pipe must be put through the nut first, and then plug the pipe, make sure that the ring in the nut is kept in place and has not come off (see figure)

The basic principle of the length of the water pipe connection is "to be able to easily drag the machine to the outside of the flow bench for the replacement of the cartridges," if the water pipe connection is too short, it is not necessary to connect it to the water pipe, but it is necessary to connect the water pipe to the water pipe. If the water hose connection is too short, it will be very difficult to change the cartridge; it is recommended to drag the machine to the outside of the flow bench to measure in the field, so that the extra length needed to change the cartridge is already included.

2.4.2Cut a 1.8-2 meter long piece of PE water pipe from the water inlet tee through hole 2 and connect it to the NO1 position marked on the machine. (See diagram)

2.4.3 Cut a piece of PE water pipe about 60-80 centimeters long and connect one end to the marked point no.b (flow restrictor) and the other end to the waste water drain hole. Wrap layers of tape around the wastewater drain hole to prevent water seepage.

2.4.4 Cut a piece of water pipe about 80-100 centimeters long and connect one end to point no.c (high pressure water cutoff control switch) and the other end to the pressure drum ball valve on the pressure type pure storage drum.

2.4.5Cut a piece of water pipe about 100cm long, connect one end to the labeled point no.d (outlet of the post-filtered activated carbon cartridge), and the other end to the inlet under the gooseneck.

Confirm that the above connection is correct, then the PE water pipe will be organized, tied with tape to put the machine back to the flow table

2.3.5Installation of the gooseneck - according to the diagram, the gooseneck faucet will be locked on the flow table on the position of the holes 1. (Please pay attention to the order of the gooseneck kit); installation is complete, the gooseneck plate up and down the trigger, the faucet left and right to confirm that the installation of the installation of a solid, will not be loosened.

2.3.7 Pressure Tank - Lock the pressure tank on top of the pressure tank, align the spout of the pressure tank on/off valve with the notch of the pressure tank, and place the tank underneath the counter or wherever you want to place it. Turn the pressure pail on/off valve to the OFF position. (See Figure . Parallel to the outlet is open, perpendicular is closed)

2.4 Connection

2.4.2Cut a 1.8-2 meter long piece of PE water pipe from the water inlet tee through hole 2 and connect it to the NO1 position marked on the machine. (See diagram)

After confirming that the above connections are correct, the PE water pipe is organized, and the machine is put back into the flow bench with a tape.

2.5 Power supply

There are two ways of supplying power:

2.5.1 Extend a socket under the machine and plug in the power cord;

2.5.2 Estimate the length from the nearest socket on the machine to the machine's location, cut it off, and then connect it to the machine, or find a spare piece of wire if it is not long enough.

After taking over, please check the smoothness of each hole, if there is any unevenness, use a file or sandpaper to smooth it out. Then, put silicone rubber in each hole, and use gloves and plastic bag to smooth the silicone rubber to prevent water from seeping under the fluid table.

2.6 Startup

Please make sure that the receiver and the nut are locked before startup

2.6.1Open the ball valve of the inlet tee group to let the water enter into the reverse osmosis system (flow for 2 minutes)

2.6.2Plug the power cord into the power outlet and make sure that the motor starts to run (touch the motor with your hand to feel some vibration)

2.6.3Put the motor into the power outlet and make sure that the motor starts to run (feel some vibration with your hand)

2.6.4The motor starts to run (feel some vibration with your hand). p>2.6.3 Close the pressure storage tank on the pressure tank switch valve, the goose neck faucet upward trigger, after a few minutes of water can be seen slowly from the goose head faucet

2.6.4 Let the water flow for about 15 minutes, the reverse osmosis membrane on the original preservation of the liquid rinsed clean, will be the gooseneck faucet off. See if the machine stops making water (touch the motor with your hand to feel no vibration).

2.6.5 Open the pressure bucket switch valve, the motor will resume operation, at this time that is the beginning of the water into the pressure type storage bucket, about 40 minutes will be full of the first bucket of water, the gooseneck faucet switch will be opened to the first bucket of water to completely leak (wash out the original bucket of chemical preservation of pharmaceuticals and impurities).

The installation procedure is completed.

Three. Maintenance

Please change the filter cartridge regularly. Your reverse osmosis filtration system has been matched by precise calculations and is guaranteed to last for several years in a state of normal cartridge replacement maintenance.

3.1 Cartridge Replacement Time-

3.3.1 Under normal use conditions, the generally recommended cartridge replacement frequency is as follows:

Cartridge

Type

First

Sludge Cartridge

Second

Activated Carbon Cartridge

Third

Refined activated carbon

Fourth course

RO reverse osmosis membrane

Post-activated carbon

Refined cartridge

Exterior

Replacement

Time 1. 3 months Half a year Half a year Variable One year

Replacement

Time 2. Exterior is covered by sludge or contaminants

The adsorption capacity is exhausted and the cartridge does not produce water

The TDS of the produced water rises or does not produce water

The adsorption capacity is exhausted

Consequences of not replacing the cartridge Blockage of the water intake, the motor is working hard and the life expectancy of the cartridge decreases

The motor is working hard and the life expectancy of the cartridge decreases, and the water does not come out

The motor works hard and the life expectancy is decreased, and the water is not produced. The motor works hard to reduce the lifespan, making no water

Water quality continues to deteriorate, bacteria breeding, affecting the safety of drinking water

3.2 Filtration status description

In Taiwan or other areas installed on the roof of the water tower, because the water tower is often negligent in cleaning, resulting in a lot of sludge deposits, such a state of affairs must be paid more attention to the replacement of the first filter element.

Total Solids Index (TDS) rise: represents a decline in the quality of water, please check whether it is up to the post activated carbon refining cartridge life, the other may be RO reverse osmosis membrane has been perforated.

Post-activated carbon filter element was originally designed to improve the taste, if the water does not feel good or the use of life to the time to be replaced, otherwise bacteria are extremely easy to grow on the surface of the activated carbon, affecting the safety of drinking water.

3.3 Filter Replacement Steps - (See Figure)

3.3.2 Unplug the power, pull the machine out of the flow table.

3.3.3 Slip the filter bottle plate handles into the first filter bottle from the bottom upwards rising upwards until it catches the grooves of the filter bottle.

3.3.4 Turn the bottle clockwise, taking care not to spill any water.

3.3.5 Remove and discard the old filter cartridge and insert the new one. Note that the bottom of the filter cartridge does snap into the cartridge holder at the bottom of the filter bottle.

3.3.6Turn the bottle back by hand in a counterclockwise direction, and then put the bottle leather glove into the bottle to tighten it after it feels a little tight. At this time, it should be noted that the water stopping rubber ring of the filter bottle should be embedded in the seat.

3.3.7 Replace the other cartridges in order.

Note 1: Because of the pressure in the pipe, it will be difficult to loosen the filter bottle. You can try to loosen the filter bottle by hitting it with a heavy object, or open the valve of the goose neck faucet and the pressure tank to relieve the pressure, which can also help to loosen the filter bottle easily.

Note 2: When replacing the activated carbon cartridge, the activated carbon powder will be stuck and affect the reverse osmosis membrane and electronic control parts of the machine, so please put it under the faucet and rinse it for one minute before use.

3.4 Pressure type storage tank sterilization cleaning

In the use of a year to a year and a half of time, it is recommended to take the following steps on your House of reverse osmosis treatment equipment for sterilization work.

3.4.1Shut off the power and water inlet ball valve switch, the pressure drum in the water leakage or storage to other containers, will be screwed down the nut, the pressure drum switch is also screwed down.

3.4.2 Use one disinfectant tablet (chlorine tablet), slightly crushed, and place it in the outlet above the pressure drum.

3.4.3 Replace the pressure tank on/off valve, pipe and nut.

3.4.4 open the power supply and water ball valve to allow the machine to resume making water into the pressure tamping storage barrel, the first barrel and the second barrel of water leakage is not used, so that is the completion of the sterilization of the barrel.

Note 1: Of course, you can also directly replace a new storage bucket.

Note 2: It is recommended that the water pipes after the reverse osmosis membrane be replaced at the same time as the disinfection to ensure that the pipes are clean.
