2.5. About unit of the length

All Fujitsu General products are manufactured to metric units and tolerances. United
States customary units are provided for reference only.
In cases where exact dimensions and tolerances are required, always refer to metric
units.

3. PRODUCT SELECTION

• Select the RB unit to fi t the total capacity and number of the indoor units to be con-
nected downstream. (Refer to Tables 1 and 2)
O.U. RB
I.U.
Calculation example: If the connected indoor units model code is 07, 09, 12 and 18.
Q1= 7,500 Btu/h + 9,500 Btu/h + 12,000 Btu/h +
18,000 Btu/h=47,000 Btu/h
Table 1) Conditions in which connection is possible
Model Name Indoor unit capacity
UTP-RU01AH 7,500 ≤ Q1 ≤ 27,000 Btu/h
UTP-RU01BH 7,500 ≤ Q1 ≤ 60,000 Btu/h
UTP-RU01CH 7,500 ≤ Q1 ≤ 96,000 Btu/h
* Indoor units connected downstream of the RB unit can operate all in the same operat-
ing mode. Indoor units within the same RB group cannot simultaneously operate heat-
ing and cooling.

For details of piping specifi cations, refer to the outdoor unit installation manual.

5. INSTALLATION WORK

5.1. Selecting an installation location

Take into consideration whether the place you install the main unit can fully with-
stand its weight.
For hanger bolts, use embedded inserts or embedded foundation bolts in the case
of new installation, and use a hole-in-anchor if already installed, and attach in a
way so that the unit's weight can be supported.
Do not install this unit in the following areas:
• Area with high salt content, such as at the seaside. It will deteriorate metal parts,
causing the parts to fail or the unit to leak water.
• Area fi lled with mineral oil or containing a large amount of splashed oil or steam,
such as a kitchen. It will deteriorate plastic parts, causing the parts to fail or the unit
to leak water.
• Area that generates substances that adversely affect the equipment, such as sulfu-
ric gas, chlorine gas, acid, or alkali. It will cause the copper pipes and brazed joints
to corrode, which can cause refrigerant leakage.
• Area containing equipment that generates electromagnetic interference. It will cause
the control system to malfunction, preventing the unit from operating normally.
• Area that can cause combustible gas to leak, contains suspended carbon fi bers or
fl ammable dust, or volatile infl ammables such as paint thinner or gasoline. If gas
leaks and settles around the unit, it can cause a fi re.
• Area where small animals may live. It may cause failure, smoke or fi re if small
animals enter and touch internal electrical parts.
• Area where animals may urinate on the unit or ammonia may be generated.
Install this unit, power supply cable and transmission cable at least 40 in (1 m)
away from a television or radio receivers. The purpose of this is to prevent TV
reception interference or radio noise. (Even if they are installed more than 40 in (1 m)
apart, you could still receive noise under some signal conditions.)
If children under 10 years old may approach the unit, take preventive measures so
that they cannot reach the unit.
Select the place to install the product after taking into consideration the following condi-
tions, and after obtaining approval from the customer.
• Install this unit in a location that has strong support and no vibrations.
• Install in a location that has enough space for this unit installation.
• Install in a well-ventilated area.
• Install in a location that is not exposed to high temperatures or humidity over a long
periods.
• Do not install the unit near a bedroom. Refrigerant noise may be heard from the pip-
ing.
