3-4. Pre-installation Test. Prior to installation, connect the unit to a suitable source of AC
power. Turn main switch on and check for quiet fan operation. Connect an ohmmeter or a
battery operated test lamp across the normally closed terminal pair on the interlock terminal
board and check for less than 1 ohm of indicated resistance.
3-5. Installation. 6600 Series Coaxial Loads must be installed in locations convenient for
servicing. Consideration should be given to adequate accessibility for maintenance and
unit replacement. No attempt is made in this handbook to present complete installation
instructions, since physical differences in plant will determine the installation procedure.
General guidelines are outlined in subsequent paragraphs.
3-6. Location. Locations selected for the 6600 Series Coaxial Loads should have an ambient
temperature below 104
°
F (40
°
C). The room should be well ventilated to prevent excessive
temperature rise and consequent derating of the unit. The maximum dissipation of the
6606, 6612, and the 6620 is 6,000, 12,000 and 20,000 watts of electrical energy. This is
equal to 20,491, 40,982, and 68,304 Btu/hr respectively. When ordered for exterior
installation, an isolated concrete pad is preferable to eliminate burn/fire hazards. The
location must allow sufficient area to prevent debris or foliage from restricting the intake or
exhaust air flow. Consideration should also be given to keeping combustible materials
away from the load.
3-7. Mounting. 6600 Series Coaxial Loads are designed to be floor mounted and should be
securely attached to the mounting surface. Adjustable legs are provided for leveling prior
to attaching to a secure surface. The enclosure rests on four fixed aluminum feet. These
are drilled for 3/8-16 machine screws.
3-8. Connections. There are two connections on conventional 6600 series convection cooled
loads: the RF connection and the thermal alarm connection. The RF connection is located
on the front panel of the unit. The thermal alarm connection is a four-pin Amphenol
cylindrical twist lock connection on the front of the load. The user must solder the alarm
leads to the terminals labeled A and B on the male component of this connector for the
circuit to be completed.
On 6600 Series Coaxial Loads supplied with fans, terminals C and D of the Amphenol
cylindrical twist lock connections are supplied for interlock leads. AC main power
connections are also supplied on the front panel of the load.
3-9. Adjustments. No field adjustments are necessary or possible.
3-10. Preparation for Reshipment. No special measures are required to prepare the Model
6600 Series Coaxial Load for reshipment. Care must be taken to protect the RF connector
and to immobilize the swivel flange. Packaging should provide protection against abrasion
and impact.
