Introduction 1
Introduction
Fan coil unit is a kind of compound device which assemble fan and surface-type coil heating-exchanger
together. Fan coil with fresh air supply system is a main type of center air-conditioner system, so it is an
important component of AC devices. Fan coil has horizontal type, vertical type, etc. A cooling (heating)
supply system usually consists of fan coil terminals and chilled water system (heated water system).
Midea
®
commercial AC fan coil is designed and manufactured on the base of advanced technology, and
utilize qualified galvanized iron as material. Due to its supper-thin design, it has such advantages: beautiful
outlook, space saving, easy installation, etc. And the most obvious advantage is that it can decrease the
outlet air Temp-difference as low as possible to make room more comfortable, as well as don’t decrease
cooling capacity output. For the large air flow volume design, it can increase room ventilation frequency,
supply more flesh air, and balance room temperature distribution. Benefiting from adoption of advanced
material and technology, it can effectively decrease the running noise and keep running smoothly. With the
advantages above, it can be widely applied in market, hospital, office building, hotel airport, etc.

Features MCAC-KTSM-2007-2
26 Compact Four Way Cassette Type
1. Features
(1) Low operation noise
---Streamline plate ensures quietness
---Creates natural and comfortable environment
(2) Efficient cooling
---Equal, fast and wide—range cooling
(3) The adoption of the most advanced 3- Dimensional Screw fan
---Reduces the air resistance passing through
---Smoothes the air flow
---Makes air speed distribution to the heat exchange uniform
(4) Fresh air makes life healthier and more comfortable.
(4) Improvement for easy installation and maintenance (only available for small four-way cassette)
---Little space is required for installation into a shallow ceiling
---Because of the compactness and weight reduction of the main unit and panel, all models can be
installed without a hoist

4. Connect the Drain Pipe
Install the drainpipe of the indoor unit
You can use a polyethylene tube as the drainpipe (out-dia. 37~39mm, in-dia. 32mm). It could be bought at
local market or from your dealer.
Set the mouth of the drainpipe onto the root of the body's pump-pipe, and clip the drainpipe and the out-let
pipe sheath (fittings) together firmly with the out-let pipe clasp (fitting).
Cautions: Use your strength carefully to prevent the pump-pipe from breaking. The body's pump pipe and
the drainpipe (especially the indoor part) should be covered evenly with the out-let pipe sheath (fittings) and
be bound tightly with the constrictor to prevent condensation caused by entered air.
To prevent water from flowing backwards into the air conditioner while the air conditioner stops, please lean
the drainpipe down toward outdoor (outlet-side) at a degree of over 1/50. And please avoid any bulge or
water deposit. (Refer to Chart 17.a)
Do not drag the drainpipe violently when connecting to prevent the body from being pulled. Meanwhile, one
support-point should be set every 1~1.5m to prevent the drainpipe from yielding (Refer to Chart 17.b). Or
you can tie the drainpipe with the connecting pipe to fix it. (Refer to Chart 17.c) In the case of prolonged
drainpipe, you had better tighten its indoor part with a protection tube to prevent it from loosing.
If the outlet of the drainpipe is higher than the body's pump joint, the pipe should be arranged as vertically as
possible. And the lift distance must be less than 200mm, otherwise the water will overflow when the air
conditioner stops. (Refer to Chart 18) The end of the drainpipe should be over 50mm higher than the ground
or the bottom of the drainage chute, and do not immerse it in water. If you discharge the water directly into
sewage is sure to make a U-form aqua seal by bending the pipe up to prevent the smelly gas entering the
house through the drain pipe.
Cautions: All the joints of the drain system must be sealed to prevent water leakage.
2. Drainage test
Check whether the drainpipe is unhindered
New built house should have this test done before paving the ceiling.
Remove the test cover, and stow water of about 2000ml to the water receiver through the stow tube. (Refer
to Chart 19)
Page 47

Turn on the power, and operate the air conditioner under the "COOLING" mode. Listen to the sound of
the drain pump. Check whether the water is discharged well (a lag of 1min is allowed before
discharging, according to the length of the drain pipe), and check whether water leaks from the joints.
Cautions:
1. If there is any malfunction, please resolve it immediately.
2. Stop the air conditioner for there minutes, check if everything is ok. If the drain hose is located
unreasonable, water overflow will cause the Alarm indicator lamp flashing (For both cooling and heating
type or cooling only type), even the water leak out from the water receiver.
3. Check the drain pump whether drain water immediately when alarm sound for the high water lever. If
the water lever can't come down below to the limited water lever, the air conditioner will stop. Restart it
until turn off the power and drain off all the water.

3. Install the drainage pipe
Check whether the height drop between the indoor unit and outdoor unit, the length of refrigerant pipe, and
the number of the bends meet the following requirements:
The max height drop ................................................................................................... 20m
(If the height drop is more than 10m, you had better put the outdoor unit over above the indoor unit.)
The length of refrigerant pipe ...................................................................... less than 30m
The number of bends ..................................................................................... less than 15
The standard length of connecting pipe is no more than 8m; choose appropriate position for both indoor and
outdoor unit to make the connecting pipe as short as possible.
Do not let air, dust, or other impurities fall in the pipe system during the time of installation.
The connecting pipe should not be installed until the indoor and outdoor units have been fixed already.
Keep the connecting pipe dry, and do not let moisture in during installation.
The procedure of connecting pipe
1. Locate the Pipe
a) Measure the necessary length of the connecting pipe.
b) Drill a hole in the wall (suitable just for the size of the wall conduit, 90mm in general), then set on the
fittings such as the wall conduit and its cover.
c) Bind the connecting pipe and the cables together tightly with binding tapes. Do not let air in, which will
cause water leakage by condensation.
d) Pass the bound connecting pipe through the wall conduit from outside. Be careful of the pipe allocation to
do no damage to the tubing.
2. Connect the pipes.
a) Connect the indoor unit at first, then the outdoor unit.
Bend the tubing in proper way. Do not harm them.
Cautions:
Daub the surfaces of the flare pipe and the joint nuts with frozen oil, and wrench it for 3~4 rounds with hands
before fasten the flare nuts. (Refer to chart 15).Be sure to use two wrenches simultaneously when you
connect or disconnect the pipes.
Use frozen oil Bend the pipe with thumb
Make the end straight
min-radius 100mm
Chart 15 Chart 16 Chart 17
b) The stop valve of the outdoor unit should be closed absolutely (as original state). Every time you connect
it, first loosen the nuts at the part of stop valve, and then connect the flare pipe immediately (in 5 minutes). If
the nuts have been loosened for a long time, dusts and other impurities may enter the pipe system and may
cause malfunction later. So please expel the air out of the pipe with refrigerant (R407C) before connection.
Expel the air (refer to the "Expel the Air") after connecting the refrigerant pipe with the indoor unit and the
outdoor unit. Then fasten the nuts at the repair-points.

Notices for bendable notices
The bending angle should not exceed 90°.
Bending position is preferably in the bendable pipe. The larger the better it is.
Do not bend the pipe more than three times.
Bend the connecting pipe of small wall thickness
Cut out a desired concave at the bending part of the insulating pipe. Then expose the pipe (cover it with
tapes after bending).
To prevent collapsing or deforming, please bend the pipe at its biggest radius.
Use bender to get a small radius pipes.
Use the market brass pipe
Be sure use the same insulating materials when you buy the brass pipe. (Thickness over 9mm in general)
3. Then, open the stem of stop valves of the outdoor unit to make the refrigerant pipe connecting the indoor
unit with the outdoor unit in fluent flow.
4. be sure of no leakage by checking it with leak detector or soap water.
5. Necessary refrigerant capacity:
When the piping is less than 8m, is no need to add refrigerant;
When the piping is longer than 8m, then add 0.03kg/m refrigerant.
Please record and reserve well the refrigerant stow capacity of your air conditioner for later maintenance.
6. Cover the joint of the connecting pipe to the indoor unit with the soundproof insulating sheath (fittings),
and bind it well with the tapes to prevent leakage.
Pipe connecting
Fasten the nut
Put the connecting tubing at the proper position, wrench the nuts with hands then fasten it with a
