Heating Mode

"HOT KEEP" function

"HOT KEEP"is operated in the following cases.

When heating is started:

In order to prevent blowing out of cool wind, the indoor unit fan stopped according to the room temperature which heating operation is started. Wait for approx. 2 to 3 minute, and the operation will be automatically changed to the ordinary heating mode.

Defrosting operation (in the heating mode):

When it is liable to frost, the heating operation is stopped automatically for 5 to 12 minutes once per approx. one hour, and defrosting is operated. After defrosting is completed, operation mode is automatically changed to ordinary heating operation.

When the room thermostat is actuated:

When room temperature increases and room temperature controller actuates, the fan speed is automatically changed to stop under low temperature condition of indoor heat exchanger. When room temperature decreases, air conditioner automatically changes over to ordinary heating operation.

Warming Operation

Heat pump type warming

With the heat pump type warming, the mechanism of heat pump that concentrate heat of outdoor air with the help of refrigerant to warm the indoor space, is utilized.

Defrosting operation

When a room is warmed with a heat pump type air conditioner, frost accumulates on the heat exchanger of outdoor unit along with the drop of indoor temperature. Since the accumulated frost reduces the effect of warming, it is necessery to automatically switch the operation to the defrosting mode. During the defrosting operation, heating operation is interrupted.

Atmospheric temperature and warming capacity

Warming capacity of heat pump type air conditioner decreases along with the drop of outdoor temperature. When the warming capacity is not sufficient, it is recommended to use another heating implement.

Period of warm-up

Since the heat pump type air conditioner employs a method to circulate warm winds to warm the entire space of a room, it takes time before the room temperature rises.

It is recommendable to start the operation a little earlier in a very cold morning.

Precaution For Installation

Please read these "Safety Precautions" first then accurately execute the installation work.

Though the precautionary points indicated herein are divided under two headings, WARNING and CAUTION, those points which are related to the strong possibility of an installation done in error resulting in death or serious injury are

listed in the WARNING section. However, there is also a possibility of serious consequences in relationship to the points listed in the CAUTION section as well. In either case, important safety related information is indicated, so by all

means, properly observe all that is mentioned.

After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please explain operating methods as well as maintenance methods to the user (customer) of this equipment, based on the owner's manual. Moreover, ask the customer to keep this sheet together with the owner's manual.

WARNING

This system should be applied to places as office, restaurant, residence and the like. Application to inferior environment such as engineering shop could cause equipment malfunction.

Please entrust installation to either the company which sold you the equipment or to a professional contractor. Defects from improper installations can be the cause of water leakage, electric shocks and fires.

Execute the installation accurately, based on following the installation manual. Again, improper installations can result in water leakage, electric shocks and fires.

When a large air-conditioning system is installed to a small room, it is necessary to have a prior planned countermeasure for the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration. In regards to preparing this countermeasure, consult with the company from which you perchased the equipment, and make the installation accordingly. In the rare event that a refrigerant leakage and exceeding of threshold concentration does occur, there is the danger of a resultant oxygen deficiency accident.

For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient, injury can result from a falling of the unit.

Execute the prescribed installation construction to prepare for earthquakes and the strong winds of typhoons and hurricanes, etc. Improper installations can result in accidents due to a violent falling over of the unit.

For electrical work, please see that a licensed electrician executes the work while following the safety standards related to electrical equipment, and local regulations as well as the installation instructions, and that only exclusive use circuits are used. Insufficient power source circuit capacity and defective installation execution can be the cause of electric shocks and fires.

Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted to the terminal connection part, through properly securing it. Improper connection or securing can result in heat generation or fire.

Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper installation can also result in heat generation or fire.

When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated refrigerant (R410A) within the refrigeration cycle. Rupture and injury caused by abnormal high pressure can result from such mixing.

Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this company can result in water leakage, electric shock, fire and refrigerant leakage.

CAUTION

Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightning rod or a telephone ground wire. Improper placement of ground wires can result in electric shock.

The installation of an earth leakage breaker is necessary depending on the established location of the unit. Not installing an earth leakage breaker may result in electric shock.

Do not install the unit where there is a concern about leakage of combustible gas. The rare event of leaked gas collecting around the unit could result in an outbreak of fire.

For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally insulate it to prevent condensation. Inadequate plumbing can result in water leakage and water damage to interior items.

19

Electric work

The electric work must be burden on the authorized engineer with qualification for electric work and grounding work, and the work must be conducted in accordance with electric equipment technical standard.

The power source for the unit is to be of exclusive use.

An earth leakage breaker should be installed.(This is necessary to prevent electric shock.) The unit must be grounded.

When you change your address or the installation place

Special technology is required for removal or reinstallation of air conditioner, consult the sales dealer. Besides, construction expense is charged for removal or reinstallation.

For inspection and maintenance

The capacity of air conditioner will decrease by contamination of inside of unit when it is used for about three years although depending upon the circumstances under which it is used, and so in addition to the usual maintenance service, special inspection/maintenance service is necessary. It is recommended to make a maintenance contract (charged) by consulting your sales dealer.

(b)When connecting the drain pipe to unit, pay suffcient attention not to apply excess force to the piping on the unit side. Also, fix the piping at a point as close as possible to the unit.

(c)For drain pipe, use hard PVC general purpose pipe VP-25(I.D.1") which can be purchased locally. When connecting, insert a PVC pipe end securely into the drain socket before tightening securely using the attached drain hose and clamp. Adhesive must not be used connection of the drain socket and drain hose (accessory).

(d)When constructing drain piping for several units, position the common pipe about 100 mm below the drain outlet of each unit as shown in the sketch. Use VP-30(11/4") or thicker pipe for this purpose.

(e)The stiff PVC pipe put indoor side should be heat insulated.

(f)Avoid putting the outlet of drain hose in the places with irritant gas generated. Do not insert the drain hose directly into drainage, where the gas with sulfur may be generated.

(g)Because the drain spout is at the position, which negative pressure may occur. So with the rise of water level in the drain pan, water leakage may occur. In order to prevent water leakage,

we designed a backwater bend. The structure of backwater H1

	bend should be able to be cleaned. As the right figure shown,				H1=100mm or the static pressure of

	use T type joint. The backwater bend is set near the air
					air sending motor
	conditioner.				H2=1/2H1 (or between 50~100mm)
	As figure shown, set a backwater bend in the middle of drain
	hose.

Drainage Test

(1)Conduct a drainage test after completion of the electrical work.

(2)During the trial, make sure that drain flows properly through the piping and that no water leaks from connections.

(3)In case of a new building, conduct the test before it is furnished with the ceiling.

(4) Be sure to conduct this test even when the unit is installed in the heating season.

Procedures

(a)Supply about 1000 cc of water to the unit through the air outlet using a feed water pump.

(b)Check the drain while cooling operation.

Installation Procedure

Air Duct

The attentive matters in installation of air suction and discharging duct

Recommend to use anti-frost and sound-absorbing duct. (locally bought)

The duct installation work should be finished before the fitment of ceiling.

The duct must be heat insulated.

The specific air-discharging outlet should be installed at the place where the airflow can be reasonably distributed.

The surface should leave a checking meatus for checking and maintenance.

The examples of improper installation

Do not use air inlet duct and take the ceiling inner side as duct instead. The result is because of the irregular outer air mass, strong wind and sunshine, the humidity is increased.

There may be water drop on the outside of duct. For cement and other new constructions, even if not taking ceiling inner side as duct, the humidity will also be so high. At this time, use glass fiber to perform heat preservation to the whole. (use iron net to bind the glass fiber)

Maybe exceeding the unit operation limit (for example: when indoor dry bulb temperature is 35 C, wet bulb temperature 24 C), it may lead to overload of compressor.

Affected by the capacity of air discharging fan, the strong wind in the outer duct and wind direction, when unit air sending volume exceeds the limit, the discharged water of heat exchanger will overflow, leading to water leakage.

Special air discharging outlet Use screw bolt to fix

Installation Procedure

Refrigerant Pipe

The gas side pipe, liquid side pipe must be faithfully heat insulated, if no heat insulation, it may cause water leakage.

The outdoor unit has been charged with refrigerant.

When connect the pipe to the unit or dismantling the pipe from the unit, please follow the figure shown, use spanner and torque spanner together.

When connect cone nut, the inner side and outside of cone nut should paste with refrigerant oil. Use hand to twist 3-4 rings, then fasten with spanner.

Referring to Table I to confirm the fasten torque. Too tight may damage nut leading to leakage.

Check if the connection pipe leaks, then do heat insulation treatment, as below figure shown. Only use seal cushion to bind the joint part of air pipe and heat insulation parts.
