GENERAL

OPERATING

PROCEDURES.

The Model F9000H-3S air conditioner is designed for operation in a

wide range of climatic conditions either continuously or

intermittently.

The amount of operator attention required will

vary depending on specific local conditions for each installation.

Under usual conditions, the air conditioner will be set up for the

appropriate mode of operation at the beginning of a season and will

only need starting and stopping and minor adjustments for the rest

of the season. Table 2-2 provides the recommended initial control

settings to establish the desired mode of operation. Minor

adjustments may be required to obtain the desired mixture of

recirculated and fresh air and the airflow patterns of conditioned

air.

NOTE

Under some climatic conditional local practices may

be established to close the fresh air damper and/or

roll down and snap in place the fabric cover during

shutdown periods.

If such practices are in effect,

the operator must first unsnap, roll up, and secure

the fabric cover and appropriately adjust the fresh

air damper before turning the MODE SELECTOR switch to

the desired operating mode.
