1. System summary

• Connectable outdoor unit

Outdoor unit of SMMS-e series.

• Corresponding system

Corresponds to a system in which there are the outside air units and the indoor air
conditioners.

• Definition

The outside air unit means an air controller for taken-in outside air.
Intake of the outside air often influences on the system so that the normal control of the air conditioner
becomes difficult or gives a large load upon air controller and cooling performance.
Therefore it is frequently adopted to handle the outside air to a certain condition before the outside air
will enter in the main air conditioner.
This handling device is called an outside air unit.

NOTE:

The outside air unit is an air conditioner provided to handle the outside air load and is not to control
the room temperature. For correspondence to the load of the indoor air controller, set an air
conditioner separately.

Installation Notes

Unit:in(mm)

1. Provide access area to the right of the unit as shown.

2. Condensate piping should slope downwards in the direction of

condensate flow, with a minimum gradient of 1in per 100 inches.

Condensate pipe should be insulated to avoid condensation.

3. Check condensate system for proper drainage before stating the unit.

4. Avoid installation of unit in Hazardous locations.

5. Filter and filter box are field provide and field installed items which

would prevent deposition of duct and dirt in the unit.

6. Install flexible duct for easy disassembly of the unit during major

service or breakdown.

7. Insulating the suction duct is recommended to avoid any

condensation on the exterior from untreated outside air.

8. Outside air louver with screen is recommended at the outside air

operating on the exterior wall.

Air intake duct

 Connect the air intake duct (Locally procured) to the inlet flange.

Wrap aluminum tape around connecting part between the air intake port flange and duct, or provide sealer
so that air does not leak.

 For the outside air intake port, attach a hood so that outside air is sucked from lower side.

And attach wire netting, etc. to the air intake of the hood.

 Set the air intake duct at descending inclination so that water

can be dr

ained even if rainwater enters in.

 Wrap the outside of the intake duct with heat insulator because it intakes cold air while heating.

Selection of installation place

Avoid installing in the following places.

Select a location for the indoor unit where the cool or warm air will circulate evenly.
Avoid installation in the following kinds of locations.
 Locations where inside the ceiling is used as route for outside air.
 Saline area (coastal area)
 Locations with acidic or alkaline atmospheres (such as areas with hot springs, factories where chemicals or

pharmaceuticals are made and places where the exhaust air from combustion appliances will be sucked into the
unit).
Doing so may cause the heat exchanger (its aluminum fins and copper pipes) and other parts to become
corroded.

 Locations with atmospheres with mist of cutting oil or other types of machine oi

l.

Doing so

may cause the heat exchanger to become corroded, mists caused by the blockage of the heat
exchanger to be generated, the plastic parts to be damaged, the heat insulators to peel off, and other such
problems to result.

 Places where iron or other metal dust is present. If iron or other metal dust adheres to or collects on the interior

of the air conditioner, it may spontaneously combust and start a fire.

 Locations where vapors from food oils are formed (such as kitchens where food oils are used).

Blocked filters may cause the air conditioner’s performance to deteriorate, condensation to fo

rm, the plasti

c parts

to be damaged, and other such problems to result.

 Locations near obstructions such as ventilation openings or lighting fixtures where the flow of the blown air will

be disrupted (a disruption of the air flow may cause the air conditioner’s performance to deteriorate or the unit to
shut down).

 Locations where an in-house power generator is used for the power supply.

The power line frequency and voltage may fluctuate, and the air conditioner may not work properly as a result.

 On truck cranes, ships or other moving conveyances.
 The air conditioner must not be used for special applications (such as for storing food, plants, precision

instruments or art works).
(The

quality of the

items stored may be degraded.)

 Locations where high frequencies are generated (by inverter equipment, in-house power generators, medical

equipment or communication equipment).
(Malfunctioning or control trouble in the air conditioner or noise may adversely affect the equipment’s operation.)

 Locations where there is anything under the unit installed that would be compromised by wetness.

(If the drain has become blocked or when the humidity is over 80%, condensation from the indoor unit will drip,
possibly causing damage to anything underneath.)

Installation under atmosphere of the high humidity

Although it has been confirmed that no trouble occurs on the unit, there is a fear of drip of the water if operation
under high humidity condition continues.

In some cases including the rainy season, especially inside of the ceiling may become high-humidity atmosphere

 In the above cases, additionally attach the heat insulator (Glass wool, etc.) to all positions of the air

conditioner, which come to contact with the high-humidity atmosphere.
In this case, arrange the side plate (Service panel) so that it is easily removed.

Use conditions

 In “COOL” mode, if temperature of the outside air is under the setup temp. +5.4°F, FAN status is automatically made. When temperature of the outside air is under 66°F,

FAN status is also made regardless of the setup temperature.

 In “HEAT” mode, if temperature of the outside air is over the setup temp. -5.4°F, FAN status is automatically made. When temperature of the outside air is over 59°F,

FAN status is also made regardless of the setup temperature.

REQUIREMENT

 In “COOL” or “FAN” mode, if temperature of the outside air is under 41°F, the operation stop automatically in order to protect the equipment.

In this case, continue the operation by selecting “HEAT” mode.

 In “HEAT” mode, if temperature of the outside air is under 23°F, the operation stops automatically in order to protect the equipment.

When operating the air conditioner with the outside air temp. under 23°F (minimum -4°F),
set temp. of the outside air to be taken in to 32 (*1)°F or upper using

a duct heater (locally procured).

For details, consult the dealer which you

purchased the air conditioner.

(*1) When 096type system with 1 indoor unit, be taken in to 41°F or upper using a duct heater.

 In “HEAT” mode, if temperature is out of range in the Use condition, the fan of the Outside Air Unit intermittently operate. So take care not to overheat a duct heater,

when use a duct heater.

MMD-AP___1HF2ULE15-3S2

REQUIREMENT

When the air conditioner is used for the first time, it will take some moments after
the power has been turned on before the remote control becomes available for
operations: This is normal and is not indicative of trouble.

• Concerning the automatic addresses (The automatic addresses are set up by
performing operations on the outdoor interface circuit board.)
While the automatic addresses are being set up, no remote control operations
can be performed. Setup takes up to

10 minutes (usually about 5 minutes).

• When the power is turned on after automatic address setup
It takes up to 10 minutes (usually about 3 minutes) for the Outdoor unit to start
operating after the power has been turned on.

Before the air conditioner was shipped from the factory, all units are set to
[STANDARD] (factory default). If necessary, change the Indoor unit settings.
The settings are changed by operating the wired remote control.
* The settings cannot be changed using only a wireless remote control, simple

remote control or group control remote control by itself so install a wired remote
control separately as well.

Basic procedure for changing settings

Change the settings while the air conditioner is not working.
