VII. POWER EXHAUST OPERATION

The power exhaust packages are factory- or ®eld-installed with vertical units and optionally installed in the return air duct- work for horizontal applications. The standard and the modu- lating power exhaust are the two packages offered. The modulating power exhaust package is equipped with a ®eld- adjustable static pressure controller to stage up to 4 power exhausts stages which will maintain a building static pres- sure. The blue sequencer located in the control box below the control board can be adjusted, by removing the covers and adjusting the set point dial to the desired building pressure. The standard power exhaust package controls up to 2 stages of power exhaust to maintain building pressure. These power exhaust stages are staged according to a percentage of the economizer dampers position.

VIII. HEAD PRESSURE CONTROL

Each unit has a fan cycling, outdoor thermostat to shut off the outdoor-fan motor at 55 F. The head pressure control per- mits unit to operate with correct condensing temperatures down to 35 F outdoor-air temperature.

IX. LOW AMBIENT KIT

Low Ambient Kit is a fan speed control device actuated by a temperature sensor. The ®eld-installed accessory is speci®- cally designed for use on this equipment and controls the condenser-fan motor speed in response to the saturated condensing temperature. For outdoor temperatures down to −20 F, it maintains condensing temperature at 100 F.

CARE AND MAINTENANCE

To ensure continuing high performance, and to minimize the possibility of premature equipment failure, periodic mainte- nance must be performed on this equipment. This combina- tion heating/cooling unit should be inspected at least once each year by a quali®ed service person.

NOTE TO EQUIPMENT OWNER: Consult your local dealer about the availability of a maintenance contract.

WARNING: The ability to properly perform mainte- nance on this equipment requires certain expertise, mechanical skills, tools, and equipment. If you do not possess these, do not attempt to perform any mainte- nance on this equipment other than those procedures recommended in the User's Manual. FAILURE TO HEED THIS WARNING COULD RESULT IN SERIOUS PER- SONAL INJURY AND POSSIBLE DAMAGE TO THIS EQUIPMENT.

The minimum maintenance requirements for this equipment are as follows:

1.Inspect air ®lters each month. Clean or replace when necessary.

2.Inspect cooling coil, drain pan, and condensate drain each cooling season for cleanliness. Clean when necessary.

3.Inspect blower motor and wheel each heating and cooling season. Clean and lubricate (if required) when necessary.

4.Lubricate bearings every 6 months if fan runs continu- ously or annually if fan runs intermittently.

5.Check electrical connections for tightness and controls for proper operation each heating and cooling season. Service when necessary.

6.Check and inspect heating section before each heating season.

7.Check and clean vent screen if needed.

WARNING: Failure to follow these warnings could re- sult in serious personal injury:

1.Turn off electrical power to the unit before perform- ing any maintenance or service on the unit.

2.Use extreme caution when removing panels and parts. As with any mechanical equipment, personal injury can result from sharp edges, etc.

3.Never place anything combustible either on, or in con- tact with, the unit.

4.Should overheating occur, shut off the electrical supply.
