2. Temperature range Standard type Cooling Heating Indoor temperature Wet-bulb temperature 10~25˚C [50~77˚F] (Note 1) Dry-bulb temperature 15~28˚C [59~82˚F] Outdoor temperature Dry-bulb temperature -5~43˚C [23~109˚F] Wet-bulb temperature -20~15.5˚C [-4~60˚F] Note 1. If units are operated for a long time at the dew point temperature of 23˚C [73˚F] or more, condensate may collect and drip from the indoor units.
3. Notes on selecting equipments (1) Notes on using the Fresh Air Intake type units 1Fresh air intake type indoor units supply pretreated outside air into the room. This type of units are not designed to handle internal thermal load. Use other types of air conditioning units (e.g., CITY MULTI system) that are capable of handling internal thermal load in combination with the Fresh Air Intake type units.
4Fan control The unit may be forced to operate in the heating mode to prevent cold draft when the return air temperature (outside air temperature sensor reading) reaches 5˚C[41˚F] or below. At the time of factory shipment, fan setting is made so that the fan will stop during the defrost cycle and when there is a problem with the entire refrigerant systems. See below for switch settings and unit operation.

How to choose the pulley (EXAMPLE) Indoor unit : PFAV-P750VM-E (50Hz) Required external static pressure : 600 Pa Required air flow rate : 250m3/min 50Hz ······Standard The fan characteristic curve shows the internal resistance is 100 Pa when the air flow rate is 250m3/min. Total static pressure = internal resistance + external static pressure =100 Pa + 600 Pa =700 Pa Read the intersection point of the total static pressure 700 Pa and the air flow rate 250m3/min in the fan characteristic curve.

(3) Piping direction 1 Lifting method ¥ When lifting the unit with ropes, run the ropes under the unit and use the lifting hole. ¥ Support the unit at four points with two ropes, and avoid giving mechanical shock. ¥ Suspension rope angle must be 40û or less, so as to avoid compressing fan guard. ¥ Use two ropes, each at least 8m [26 ft.] in length ¥ Use ropes strong enough to support the weight of the unit. ¥ Always suspend the unit from four corners.
2 IInstallation When the pipes and/or cables are routed at the bottom of the unit, make sure that the through hole at the base of the unit does not get blocked with the installation base. When the pipes are routed at the bottom of the unit, the base should be at least 100 mm [3-15/16 in.] in height.

6 Twinning on the outdoor unit side • The tilt angle of the twinning pipe The tilt angle of the twinning pipe must be within ±15 ° with the horizontal plane. Tilting the twinning pipe more than specified will cause damage to the unit. • The length of the straight part of the pipe before the branching For the twinning kit, always use the accessory piping parts. The length of the straight part of pipe connected in front of the twinning pipe must be 500 mm [19 in.] or longer.

If not, it may cause improper operation.
(4) Weather countermeasure In cold and/or snowy areas, sufficient countermeasures to wind and snow damages should be taken for operating unit in normal and good condition in winter time. Surround the units with snow nets or fences to protect them from snow. Even in the other areas, full consideration is required for installation of unit in order to prevent abnormal operations caused by wind or snow.
Countermeasure to wind Referring to the figure shown below, take appropriate measures which will suit the actual situation of the place for installation. A unit installed alone is vulnerable to strong winds. Select the installation site carefully to minimize the effect of winds. To install a unit in a place where the wind always blows from the same direction, install the unit so that the outlet faces away from the direction of the wind.

(3) Installing the Indoor Unit WARNING Install the unit on a level surface. • If the unit is installed on an incline, water leakage or malfunctions may result. Check for straightness with a level. WARNING Do not stand on the unit. • You may fall down or the item may fall, causing injury. CAUTION Properly dispose of packing materials. • Pallets and the nails on the pallets can pose the risk of injury. • Plastic bags can pose suffocation and choking hazards: keep out of the reach of children.
Notes on when an optional plenum chamber is installed The unit described in this manual is designed to be used with a duct. When an Optional plenum chamber is used, an adjustment of the pulley is required. • Refer to the manual that came with the plenum chamber for how to install it.
Important notes on pulleys and pulley belts • Adjusting the variable-width pulley Adjust the PC ø of variable-width pulley according to the procedures described below. 1) Loosen the setscrew holding the fixed and the sliding discs in place. 2) Turn the sliding disc counter-clockwise until no gap is left (0 mm) between the fixed and the sliding discs. 3) Select the PC ø in Table 1 that is closest to the one to be used.
• Horizontal pulley alignment and proper belt tension 1) The fan pulley and the motor pulley must be aligned to meet the criteria shown in Figure 1 and Table 1. 2) Set the tension for the V-belt so that the deflection force falls within the range as shown in the table in! !7. 3) After the belt has been broken in on the pulley (after 24 to 28 hours of operation), check the belt for looseness and adjust the belt tension as specified in step (2) above as necessary.
(4) Separating the indoor unit to allow for easy transportation Instructions for separating the P500, P600-F indoor unit into parts The indoor unit can be separated into the base block, fan block, and other parts. Place the unit on a level surface before separating the unit. Base block net weight The dimension of the base block after it is separated from the other parts is Net weight marked with ✻ in the figure below.
• Instructions for separating the P750, P900-F indoor unit into parts The heat exchanger block can be separated from the main body of indoor unit (Brazing is required). Place the unit on a level surface before separating the unit. indicates the surface to split up. The dimensions of the base block after being separated from the heat exchanger block are marked with ✻ in the figure below.
f. Remove supporting plates 13 on both sides of the drain pan B 12 . This is the separation process. Use caution not to damage or scratch the unit during transportation. Take extra precautions when transporting the heat exchanger to prevent damaging its fin or heat transfer tube from shock. 2) Reassemble in the reverse order as above. Replace all fixing screws and bolts back in, and tighten each of them to the proper tightening torque.
