6.2 Connections

In connecting the unit, several items must be addressed. They are:

6.2.1 Structural Support

The unit can be installed directly on the floor of on the raised floor without the need for any special
support. The floor should be level. Gasket material should be placed between the bottom perimeter
of the unit and the floor on the downflow unit to act as vibration isolator. The gasket should be
foam, ½" x 3/8". No gasket is needed on the upflow unit.

6.2.2 Electrical Support

A fused disconnect or a HVAC approved circuit breaker must be field provided and install per the
National Electric Code (NEC). There is access to the unit for electrical connection through the unit
bottom or the top panel on the unit. Be sure unit is properly grounded.
A fused disconnect must also be provided for the air cooled condenser/condensing unit for air
cooled units and dry fluid cooler of the glycol cooled units..

6.2.3 Condensate Drain Connection

This must be equipped with 3/4" O.D. drain line. The contractor must provide and install a P-trap in
this line at the lowest point in the unit or below the unit. A minimum slope of 1/4" per foot must be
provided on the horizontal run.
carry over into the air space. The p-trap must be calculated as per Figure 7 below. After
installation of the p-trap, verify trap operation by running the system blowers at full
speed and adding water to the drain pan, water should drain out of the condensate pan
and through the trap with supply fan running at full speed.
Condensate water will not drain thus possibly causing water
