KWIKOOL KPO PORTABLE AIR CONDITIONERS
18
NOTE
For the heat function to work properly, supply and return air must
be in the space being heated. The system works by heating the air
that is recirculating to the system and will raise the overall tem-
perature of the space to the set point, if properly sized.
SECTION VII MAINTENANCE
A AIR FILTERS
The KwiKool comes from the factory with filters installed on the evaporator inlet to prevent dust and de-
bris from entering the system and circulating in the conditioned space. Factory installed filters are a
disposable type and must be periodically checked and replaced based on the air quality of the condi-
tioned space.
CAUTION
Failure to maintain the filters will cause restricted airflow and can
lower overall unit performance.
The air filter(s) are in the supply air return.
1. Remove the return air panel by turning the slotted lock fastener to the horizontal position and lift to
remove the panel.
2. Remove and replace the filters.
3. Return the air panel to its designated location and turn the slotted lock fastener to the vertical
(locked) position.
B CONDENSER DRIVE BELTS
For KPO12 and KPO25 systems only, the KwiKool moves air over the condenser coil to remove heat
from the conditioned space by way of a motor that drives a blower wheel. This wheel turns by way of a
pulley and belt system.
1. Inspect/adjust these belts every 60 days of operation, replace as needed.
2. Located in the condenser access compartment on the control end of the KPO, release the two slot-
ted fasteners to give the operator access to the condenser belts and motor.
3. Adjust the tension on the belts by adjusting the motor base.
CAUTION
Failure to maintain the drive belts will cause low performance,
high-pressure trip or, in extreme cases, damage to the blow-
er/motor in the event of a belt breaking. DO NOT ADJUST THE
DRIVE PULLEY.
