Friedrich Mw07y3jm Owner's Manual
• Do not cool excessively indoors. This may be harmful for your health and may consume more
electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors or windows closed tightly while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool indoor air quickly.
• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air
conditioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the
air flow or weaken the cooling / dehumidifying functions.

Here are some tips that will help you minimize power consumption when you use your air conditioner.
TIPS FOR SAVING ENERGY
• Use caution when unpacking and installing.
- Sharp edges may cause injury.
• Thickness of copper pipes used are as shown “Flaring work” Table.
- Never use copper pipes thinner than that in the table even when it is available on the market
• Do not use copper pipes having a collapsed.
- Otherwise, the expansion valve or capillary tube may become blocked with contaminants.
• For R410A model, use piping, flare nut and tools which is specified for R410A refrigerant.
- Using of (R22) piping, flare nut and tools may cause abnormally high pressure in the refrigerant
cycle (piping), and possibly result in explosion and injury.
• It is desirable that the amount of residual oil less than 40 mg/10m.
• Do not turn on the breaker or power under condition that front panel, cabinet, top cover, and control
box cover are removed or opened.
- Otherwise, it may cause fire, electric shock, explosion or death.
• If the air conditioner is installed in a small room, measures must be taken to prevent the refrigerant
concentration from exceeding the safety limit when the refrigerant leaks.
- Consult the dealer regarding the appropriate measures to prevent the safety limit from being
exceeded. Should the refrigerant leak and cause the safety limit to be exceeded, hazards due to
lack of oxygen in the room could result.
• Use a vacuum pump or inert (nitrogen) gas when doing leakage test or air purge. Do not compress
air or oxygen and do not use flammable gases.
- Otherwise, it may cause fire or explosion. There is the risk of death, injury, fire or explosion.
Operation
• Do not share the outlet with other appliances.
- It will cause an electric shock or a fire due to heat generation.
• Do not use the damaged power cord.
- Otherwise, it may cause a fire or electrical shock.
• Do not modify or extend the power cable.
- Scratches or peeling insulation on the power cables may result in fire or electric shock, and should
be replaced.
• Take care so that the power cord may not be pulled during operation.
- Otherwise, it may cause a fire or electrical shock.
• Unplug the unit if strange sounds, smell, or smoke comes from it.
- Otherwise, it may cause electrical shock or a fire.
• Keep the flames away.
- Otherwise, it may cause a fire.
Select the best Location
- There should not be any heat or steam near
the unit.
- Select a place where there are no obstacles
around the unit.
- Make sure that condensation drainage can
be conveniently routed away.
- Do not install near a doorway.
- Ensure that the gap between a wall and the
left (or right) of the unit is more than 4in
(100mm). The unit should be installed as
high as possible on the wall, allowing a
minimum of "A" from ceiling.
- Use a metal detector to locate studs to
prevent unnecessary damage to the wall.
* Recommended height 6.5ft from the floor.
* Features may change according to the type
of model.
Fixing Installation Plate
The wall you select should be strong and solid
enough to prevent vibration.
1 Mount the installation plate on the wall
with type "A" screws. If mounting the unit
on a concrete wall, use anchor bolts.
- Mount the installation plate horizontally
by aligning the centerline using Horizontal
meter.
<7k>
2 Measure the wall and mark the centerline.
It is also important to use caution concerning the location of the installation plate.
Routing of the wiring to power outlets is
through the walls typically. Drilling the hole
through the wall for piping connections
must be done safely.

Drill a Hole in the Wall
- Drill the piping hole with a Ø2-9/16”(65mm)
hole core drill. Drill the piping hole at either
the right or the left with the hole slightly
slanted to the outdoor side.
Flaring Work
Main cause for gas leakage is due to defect of
flaring work. Carry out correct flaring work in
the following procedure.
1 Use the piping kit accessory or the pipes
purchased locally.
2 Measure the distance between the indoor
and the outdoor unit.
3 Cut the pipes a little longer than measured
distance.
4 Cut the cable 1.5m longer than the pipe
length.
1 Completely remove all burrs from the cut
cross section of pipe/tube.
2 While removing burrs put the end of the
copper tube/pipe in a downward direction
while removing burrs location is also
changed in order to avoid dropping burrs
into the tubing.
- Remove flare nuts attached to indoor and
outdoor units, then put them on the
pipe/tube which have completed its burr
removal.

3 Press the lower left and right sides of the
unit against the installation plate until the
hooks engage into their slots (clicking
sound).
4 Finish the assembly by screwing the unit
to the installation plate by using two pieces
of type "C" screws. And assemble a chassis cover.
Checking the Drainage
1 Pour a glass of water on the evaporator.
2 Ensure the water flows through the drain
hose of the indoor unit without any leakage
and goes out the drain exit.
1 The drain hose should point downward for
easy drain flow.
