5.1Drycooler Location

The drycooler should be located for maximum security and maintenance accessibility. Avoid ground- level sites with public access or areas which contribute to heavy snow or ice accumulations. To assure adequate air supply, it is recommended that drycoolers be located in a clean air area, away from loose dirt and foreign matter that may clog the coil. In addition, drycoolers should not be located in the vicinity of steam, hot air or fume exhausts. Also, drycoolers should not be located closer than 3 feet (1 meter) from a wall, obstruction or adjacent unit.

5.2Drycooler Installation

For roof installation, mount drycoolers on steel supports in accordance with local codes. To minimize sound and vibration transmission, mount steel supports across load bearing walls. For ground instal- lation, a concrete pad will provide adequate support. Drycooler legs have mounting holes for securing the drycooler to steel supports or concrete pad.

5.3Electrical Connections

Refer to equipment nameplate regarding wire size and circuit protection requirements. Refer to elec- trical schematic when making connections. Make all wiring and electrical connections in accordance with local and national codes.

! WARNING

Use voltmeter to make sure power is turned off before making any electrical connections.

5.3.1Line Voltage

Line voltage electrical service is required for all drycoolers at the location of the drycooler. This power supply does not have to be the same voltage as the indoor unit. This separate power source may be 208, 230, 460, or 575 V, 60 Hz; or 200, 230, or 380/415 V, 50 Hz. The disconnect switch is factory-sup- plied and mounted in the electric panel.

5.3.2Low Voltage

A control interlock between the drycooler and the indoor unit is required and is connected between 70 and 71 in the handy box of the indoor unit and the pump and drycooler control box of the drycooler. NEC Class 1 wiring is required.

5.3.3Pump and Drycooler

All wiring to the pump and drycooler from the control box should be done in accordance with the elec- trical schematic on the inside lid of the drycooler control box and with local and national codes.
