For Ceiling Kit Users - KwiKool KPHP Series Operation Manual

3. Be sure the area where you are ducting can absorb the Discharge Air and is open
enough to keep the system from returning its own Discharge Air. Your KwiKool System
must have fresh Make-up Air going to the condenser to operate.
a) Install the replacement ceiling panel(s) in the ceiling grid with the duct attached.
b) Connect the open end of the duct to the flanges on your KwiKool System.
c) Secure with supplied clamps.
G. FOR CEILING KIT USERS
The standard two-duct ceiling kit (CK-12) is recommended to be used with KwiKool Systems
for optimum performance. KwiKool's KPHP Systems may be used for primary, supplemental
or standby cooling or heating. Using KwiKool's exclusive ceiling kit ensures that you are able
to utilize 100% of the units rated capacity and without creating a negative pressure in your
conditioned space. KwiKool System's exclusive In and Out (IO) integral condenser system
isolates both the Condenser Discharge Air and the Condenser Make-up Air from the condi-
tioned space.
The space where the Make-up Air and Discharge
Air is directed (normally above a drop ceiling) must
be well ventilated and large enough for the Dis-
charge Air to be absorbed.
Discharge Air is prevented from entering the Make-up Air inlet by way of a factory installed
deflector on your Ceiling Kit. Make sure that the deflector is on the discharge (rear) duct from
the unit.
If the condenser discharge and return space is unventilated, closed off, or unable to han-
•
dle the Discharge Air, the Make-up Air will return the Discharge Air. This will lead to the
unit tripping its High Pressure Reset (HP Reset) safety switch while in COOL mode. If
this occurs, you will get an HP on the control panel.
When HP appears on the control panel, it indicates high pressure in the unit. To resolve,
•
fix the lack of Make-up Air and reset the HP Reset switch in accordance with the instruc-
tions in Section IX, Troubleshooting Guide.
If in HEAT mode and ducted into a confined space you will notice diminished perfor-
•
mance, rapid Supply Air cycling and/or coil freezing.
The ceiling kit replacement panel is not limited to
ceiling use and may be placed or fastened to any
vertical or horizontal surface, providing the Dis-
charge and Make-up Air is able to be directed to
the space where it is mounted. For areas with a
closed ceiling or no ceiling use the double flange
ceiling kit method or extended duct method.
Make sure that the deflector is on the discharge (rear) duct from the KwiKool System. If
•
the condenser discharge and return space is unventilated, closed off or unable to handle
the heat load, the Make-up Air will continue to get hotter until the system is not able to
handle the high heat buildup.
