2.6.3 Condensate Drain Line

2.6.3.1 Gravity Drain

A 7/8 inch OD copper (sweat type) line is provided to

drain the condensate drain pan. This line also drains

the humidifier, if applicable. The drain line must be

located so it will not be exposed to freezing tempera-

tures. The drain line should be the full size of the

connection. See the installation drawing provided with

your unit for the size and location of the condensate

drain line.

NOTE

During normal operation the optional humidifier

drains (hot) water into the condensate drain

line. As an option, a separate drain line may be

provided for the humidifier.

2.6.3.2 Condensate Pump (See Figure 4)

A condensate pump is used for automatic removal of

condensate from the air conditioner and flush water

from the humidifier (if applicable). A p-trap must be

installed for proper condensate drainage. The height of

the trap must be a minimum of 2 inches on most

standard systems to ensure proper water drainage of

the drain pan. The condensate pump discharge line

should be 1/2 inch OD maximum copper or vinyl tubing

to prevent excessive back flow to unit.

NOTE

Pour some water into the condensate drain(s)

prior to start-up. This fills the trap and prevents

air from being drawn up the drain lines.

2.6.4 Humidifier (Optional)

CeilAiR

systems utilize an electrode steam humidifier.

The humidifier empties into the condensate drain line

during the flush/drain cycle. A water supply line must

be connected to the copper tubing connection supplied

by the factory. Refer to the installation drawing pro-

vided with your unit for the size and location of the

connection. The humidifier requires normal tap water

as the water supply. If the supply water is high in

particulate, an external filter may be needed.

CAUTION

Do not use demineralized water.

Refer to the humidifier operator’s manual, supplied with

the equipment, for complete manufacturer’s informa-

tion on the humidifier and the supply water recommen-

dations.
