Users must install the water purifier with the help of professionals by st-
rictly following the installation specification set out in the "Product Insta-
llation & Operation Manual" (hereinafter referred to as manual), and use
the water purifier according to the instructions in the manual. Otherwise
the company does not assume any economic or legal responsibility for
the water purifier damage or leakage and consequential property dam-
age due to improper installation and usage of water purifier.

ere is any leakage, and avoid property damage caused by leakage.
2. The water purifier is only intended for household use, and may not
be suitable for other purposes.
3. For the water purifier maintenance and filter cartridge replacement,
use the replacement parts authorized by Honeywell Environmental &
Combustion Controls (Tianjin) Co., Ltd..Quality problems, degradation
of operational performance or property damage caused by using una-
uthorized parts or accessories are not covered in the guarantee.

Important Notes

Safety Precautions
3
At the inlet of the water purifier, the water quality must be the municipal
tap water quality which meets local standard.
Do not install the water purifier in the water supply pipe, whose press-
ure exceeds 0.6MPa. If the water inlet pressure exceeds 0.6 MPa, the
pressure reduce valve (purchased separately) must be installed.
The water inlet temperature range of the water purifier is 5 ~ 38°C;wat-
er temperature exceeding 38°C may damage seals and cause leaka-
ge; water temperature below 5°C may cause water to freeze and lead
to the pipe rupture and leakage.
Install the filter cartridge in a correct order, otherwise the water purifier
cannot perform its intended function.
Do not install the water purifier reversely, and connect the water inlet
pipe to the outlet.
Do not install the water purifier in direct sunlight or at a places where it
is exposed to hazardous chemicals or may be damaged by falling or
collision.
Do not install the water purifier near any source of heat.
Do not install the water purifier upside down.

* The rated maximum capacity is the effective treatment capacity after adding the standard
solution in the whole process according to the inspection rules required by Ministry of Health.
The actual water treatment capacity may vary depending on local water quality and operating
environment.

Brief Introduction
Caution：
The water purifier is designed to work under the table near the sink in the kitchen.
The supply pipe connects to your existing water connection pipe with a tee joint.
This water purifier is designed to purify the drinking water.

Do not let the supply and drainage lines or purifier be frozen. If the water tem-
perature or the ambient temperature drops below 5°C, turn off the supplying
water pipe and discharge the water inside the purifier. The freeze of water su-
pply pipe or purifier may cause failure or damage of enclosure and water pipe
and possible injury.

The water purifier filter cartridges need to be changed regularly. Replacement cycle of
the PP dense filter cotton, the MS dense composite molecular sieve (sterilization) and UF
membrane will be indicated at the faucet (separate package) base. The green light
indicates it is within the safe range, the yellow light indicates it needs to be replaced
(close to safe range), and the red light indicates it exceeds the safety range, and must
be replaced.

Step 1：
Fix the filter adapter with screws, as
shown in Figure 3.
Step 2：

Install PP dense cotton filter cartridge to
the first stage of the filter adapter, and
MS composite molecular sieve filter
cartridge (sterilization) to the second
stage of the filter adapter, and UF
membrane cartridge to the third stage of
the filter adapter.
Align the two pipes of the cartridge to the
connection holes in the filter adapter, and
rotate counter-clockwise to the end.

Step 3：
Cut the 1/4”PE pipe into 2 sections. One section is used to connect tee joint ball valve
and filter adapter, and the other section is used to connect faucet and filter adapter, as
shown in Figure 5.
Step 4：Hang the whole set of the water purifier on the filter adapter screws.：

Installation Instructions
1. Turn on the water inlet valve and small ball valve.
2. Open the faucet to let the water flow into the water purifier. Due to the role of carbon
particles and bubbles, the water may seem a little muddy at the start, which is normal.
3. Continuously flush new water purifier for about 10 minutes, until the water becomes
clear and no bubbles, and it can provide the drinking water.

1. Check water purifier and components regularly to avoid leakage,
which may cause damage to property.
2. When you go out or do not use the water purifier for a long time, pl-
ease shut off the water inlet of the purifier (turn off the water inlet b-
all valve).
If the purifier has not been used for 24 hours, please flush it for 5-10
seconds. If the purifier has not been used for more than 5 days (mo-
re than 3 days in summer) ,please flush it for 10 minutes before use.
Do not keep the filter unused for long after the water flows through,
especially in summer, generally no more than 14 days.
3. In case of any following situations, shut off the input water of the pu-
rifier (turn off the water inlet ball valve) immediately, and contact the
service provider as soon as possible.
If the pipe or related parts of the water purifier are leaking.
If the related components of the water purifier malfunction.
If any other anomalies or failures occur.

The set of capacity and replacement time recommended for
filter cartridges at various stages
Replacing the filter components
Table 3
1. Align the filter cartridge with the filter adapter, and rotate clockwise until it stops. The
filter cartridge automatically comes off.
2. Select the corresponding replacement filter cartridge, align the 2 connection pipes
with the connections holes in the filter adapter, and rotate counter-clockwise until it stops.
3. When replacing the water purifier water cartridge, there is no need to turn off the water
inlet valve, because the filter adapter will automatically turn off the water outlet.
4. When removing the filter cartridge, there may be a little water coming out of the filter
cartridge. Wipe the water off.
Care & Maintenance

The set of capacity and replacement time may be adjusted based on the water quality
and usage.
Every filter cartridge of the product uses flow and time dual control. Whichever reaches
the set value, the faucet will give indication. See the faucet manual for details.
1. The recommended replacement cycles for various filter cartridges of the water purifi-
er are estimated by referencing the average indicator of water supply at various regions.
When the water quality at the user's site and the purifier usage are quite different from
the average indicator, filter cartridge usage and estimated cycle may be significantly di-
fferent,such as early clogging or failure of filter cartridge. The actual usage will be used
as the basis for replacing the filter cartridge, and contact the service provider for the
setting.
2. The estimation of filter cartridge usage cycle is based on the average household wa-
ter consumption. The usage cycle is only suitable for household use, and may not be
suitable in public places with large water consumption.
