kH Keeper Online Manual

1. Introduction

This online manual is just interactive shorter version of full manual, how to handle with KH Keeper device. Full manual you can find here.

The manual includes information about the device functions, which contains the software version number 0.5.3. The software version information is always in the lower right corner of the screen under the product serial number. If the software version is older, proceed with device software update to get access to the latest features.

2. Unboxing

The following items are included with your kH keeper device (see graphic below):

• 10ml high measuring cup for calibrating the reagent dosing pump,

•  two sachets with powder to calibrate the pH4 and pH7 probe,

• a glass beaker for kH measurements installed in the device,

• magnetic stirrer installed in the device,

• connection pipes installed on the pumps inside the device,

• spare connection tubes in a bag,

• a magnet used to reset the device,

• a set of two hoses with a diameter of 2 / 5mm for connecting a discharge pump aquarium water with a water filter and for connecting a pump that drains the water after measuring without a water filter,

• a 1 / 3 mm diameter hose with a plastic tube for taking a reagent,

• 100ml high measuring cup for calibrating the pump collecting water from the aquarium,

• 12 V / 2 A power adapter

3. The front correct opening and closing

For the correct operation of the equipment, it is important to handle the components properly. Please take a look how to properly open the front of the device. Before pulling, try to gently bend the front to the right and left with your fingers. When closing, be sure to slide in the front at the bottom of the device first, then click into place.

4. Assembly and disassembly of the measuring beaker

If you need to clean the device or disassemble the glass beaker, follow the steps below:

• Gently remove the pH probe from the plastic holder,

• Pull out the connector of the pump that pours water from the aquarium, which is located in the beaker on the right side, from the plastic holder. Pay attention to the installed tube to not damage it,

• Pull the connector of the emptying pump out of the plastic holder gently after the test, which is provided in the beaker to its left. Pay attention to the installed tube to not  damage it,

• Gently pull out the glass beaker, pay attention to the magnetic stirrer which is inside the glass beaker so do not lose it.

• Please remember to leave the  piece of plastic under the glass beaker. The purpose of this is to ensure the beaker does not move and positions the plastic tubes to the bottom of the beaker.

When assembling the kit, proceed in the reverse order. When attaching the probe, insert it into the slot in the holder, lower it as far as possible and press it from below with a rubber cap. Try to keep the probe mounted as close to the vertical position as possible.

5. Device installation

Make sure that the device is installed in a place that allows easy regular maintenance. The device is also suitable for wall mounting. There is a magnetic stirrer in the glass beaker, be careful not to lose it.

One of the most important elements for the proper operation of KH Keeper is the correct connection of the appropriate hoses. The first one, a plain hose that drains the water after measuring, connect by screwing the cap to the "out" input, the other side, place in the waste container. The thinnest hose with a plastic tube, that taking a reagent, connect to the “reagent” input. The hose with the water filter mounted in the middle, that connecting a discharge pump aquarium water, must be connected to the “aquarium” input.

After connecting correct hoses to the KH Keeper, please follow steps below:

• Try to place the reagent container as close to your kH keeper as possible, preferably at the same height or maximum 20 cm below.

• Connect the device to the power socket using a dedicated 12V / 2A power supply.

• On your computer, tablet, laptop or smartphone, display the list of Wi-Fi wireless networks available on the selected device, then search for and connect to the network which name corresponds to the serial number of the device, according to the formula:
  RFKHXXXXXXXXXXXX
  then put the password, which is reeffactory (the same for all our devices);
  open a browser and type www.khkeeper.io;
  choose your language;
  set the kH range suitable for your tank (by default from 7.00 to 8.00);
  connect the device to your home Wi-Fi wireless internet network. If the network is secured, enter the password that protects the home network against unauthorized access;
  create a free account on Smart Reef system by clicking the "Create a free account" button. Remember that you need to connect to the Internet through your home Wi-Fi router to do this.

6. Preparation of the reagent

Make sure that you have purchased a dedicated Reef Factory reagent for measurements with the device. It must be purchased separately because it is not included with the device. If you do not have a dedicated reagent, the measurement will not be possible (result will be incorrect). The reagent we offer is condensed and it is necessary to dilute it in RO water in a proportion of 1 to 9. This means that the preparation of 1 liter of the ready solution for measurements requires mixing 100 ml of the condensed reagent and 900 ml of RO water. Below is a table with calculations on how to properly prepare a reagent of a specific capacity.

7. Calibration procedure

After correct disassembly of the glass beaker, you can start calibrating the device. Start the calibration by opening the "CALIBRATE" menu in the Smart Reef application. Select "PH Probe". Press the "begin calibration" button. Immerse the probe in the PH4 solution. Before starting this process, remember to properly prepare the reagent. Click OK and wait 60 seconds. Then Click OK. Remove the probe from the PH4 solution. Dry thoroughly and immerse in the PH7 solution. Click okay and wait 60 second again.

Start calibrating the reagent pump with 10ml measuring cup. After pressing the button “reagent pump (A)” additional functions will be displayed. To properly calibrate the pump, fill the hose using the “fill the circuit” function. Pour out any contents of the measuring cup so as to be empty and then start the process of calibrating the pump using the "begin calibration" button. Wait until the information will display in application. When the pump finishes this operation, check the amount of water poured in, write it in the box and confirm with "OK".

Repeat the operation with the aquarium pump. Make sure that the entire hose is filled with water and that there are no air bubbles inside it, in addition, a small amount of water should be poured through the hose. Press the button to initiate the calibration and insert a 100ml measuring cup. Then press "START". After pouring in the right amount of liquid, measure the amount and write it in the window, confirming with "OK".
