SAFETY FOR USE Before conducting installation work, please read this “SAFETY FOR USE” carefully for correct installation. Since the caution items shown here contain important description relative to safety, please observe them without fail. Warning Erroneous handling gives a high possibility to induce serious results such as death or heavy injury. Caution Erroneous handling may induce serious injury depending on the situation.
PAGE 4
Caution Arrange the configuration of wiring not to bring up the panel and terminal cover, and fasten the panel and terminal cover securely. The poor mounting of the panel or terminal cover may cause the heat generation of the terminal connection, a fire or electrical shock. Never install on the place where a combustible gas might leak. The gas may ignite or explode when the gas leaks and collects in surround of the unit.

SELECTION PROCEDURE 1. Model Selection (With actual examples) First step, to select the approximate model: Based on the cooling load and the cooling capacity listed in the capacity table, select the applicable model.
PAGE 10
(Step-3) Calculation of net capacity Based on the indoor conditioned temperature (WB,DB), designed outdoor temperature (DB), and the actual air flow obtained in Step-2, obtain the gross capacity from the gross capacity tables (pages 9~16). Then, calculate the net capacity from the formula below by using the fan motor input obtained in Step-2. Net capacity (kW) = Gross capacity (kW) - Fan motor input (kW) Example: PRHG-10, 50Hz cooling Condition: Indoor conditioned temp.

INSTALLATION All series of air conditioners are designed for outdoor installations and are to be placed on a slab or rooftop, however if the air conditioner is to be installed in a plant room application, please contact your equipment supplier prior to installation. Access for both service and installation must be provided to the compressors, control wiring and fans as shown below. 1. Space required around units (1) Care must be taken to prevent recirculation air.
PAGE 40
3. Duct construction (1) Series PRHG side flow units are equipped with horizontal supply and return air openings. Duct connection to the unit should be made with duct flanges and secured directly to the air openings with flexible duct connectors to avoid normal noise transmission. (2) For vertical air supply, a field supply plenum should be used. The figure below shows the recommended method for duct connection. (3) Series PRHG down flow units are equipped with vertical supply and return air openings.
PAGE 41
7. Modification method of fan direction (From side flow to down flow) Series PRHG side flow units are able to modified to down flow at field. In case of needing down flow model, you can modify to down flow as below method. Preparation) Please confirm below accessory parts. 1.Side inlet cover 1 piece Attach on the top surface of PRHG side flow unit. 2.Casing leg 2 pieces 4 pieces Attach on the inside surface of service panel.( 8,10MYA ) Attach on the inside surface of service panel.

INSTRUCTIONS FOR USE 1. Check points for operation Check the following points before you operate your air conditioner. (1) Check that there is nothing blocking the flow of air from the air outlet into the air inlet. Indoor Side Outlet grille Inlet grille Ceiling Ceiling Obstacle blocking air inlet Obstacle blocking air inlet Outdoor Side (2) Make sure the air conditioner is properly grounded by checking the ground terminal .
PAGE 47
2. Caution for use Keep the following points in mind to safeguard against failures and break downs. • For safety, confirm that the earth terminal has been connected to the earth wire correctly. • Never block or cover the unit’s intakes or outlets. It will reduce the unit’s efficiency. • To start the unit again after once stopped, be sure to turn the start switch on after 3 minutes elapsed.

3.5 When the air conditioner is not to be used for long time If the air conditioner is not to be used for a long time due to a seasonal change, etc., Please do the following work. 1. The power supply switch is turned off. If the power supply is kept on, several watts or several tends of watts will be wasted. Also, the accumulation of dust, etc., can result in fire. 2. Filter, eliminator and drain pan are cleaned. Pay attention to throw dust in the drain. 3.

4.5 Disposing of the unit When you need to dispose of the unit, consult your dealer. If pipes are removed incorrectly, refrigerant (fluorocarbon gas) may blow out and come into contact with your skin, causing injury. Releasing refrigerant into the atmosphere also damages the environments. 4.6 Maintenance and inspection (1) If the air conditioner is used throughout several seasons, the insides can get dirty, reducing the performance.
