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.Clearances (1) Care must be taken to prevent recirculation of the condenser air.
PAGE 53
3.Duct Work (1) All series 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. PRH unit Vertical air plenum Plenum divider Insulation (2) For vertical air supply, a field supply plenum should be used. The figure below shows the recommended method for duct connection.
PAGE 54
5.Electrical Wiring Remove the panel on the right side (PR,PRH-5 10) or the rear side (PR,PRH-15,20) of the unit and connect the units power supply wiring to the proper terminals in the control box, as shown below.

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 Unit Outlet grille Inlet grille Ceiling Ceiling Obstacle blocking air inlet Obstacle blocking air inlet Outdoor Unit Obstacle blocking air inlet (2) Make sure the air conditioner is properly grounded by checking the ground terminal .
PAGE 56
2.CAUTION FOR USE Keep the following points in mind to safeguard against failures and breakdowns. (1) This air conditioner does not restart within 3min. after shut down. (These models have a crankcase heater in the compressor. If the air conditioner is shut down for a short time, please do not turn the power switch to OFF, but turn the operation switch to OFF.) (2) If the air conditioner is shut down by a power failure, set the operation switch to OFF.
PAGE 57
4. PREPARING FOR OPERATION AFTER PROLONGED SHUTDOWN When the usage season starts, proceed with the following before starting operation: (1)Clean the air filter. (2)Do not use the unit immediately. Turn the main power switch on for a period of 3 hours before restarting cooling / heating operation. This allows the compressors to come up to the correct operation temperatures. Failure to do this, could cause compressor failure. 5.
