Preparation for Storage
Supply Fans
1 .
Depending on local climate conditions, condensate
may collect on components inside the units. To prevent
surface rust and discoloration, spray all bare metal parts
with a rust preventive compound.
Cabinet Sections
Once a month, open a door on each section and verify that no
moisture or debris is accumulating in the unit.
Control Compartment
1 .
Daikin Applied recommends that the electronic control
equipment in the unit be stored in a 5% to 95% RH (non-
condensing) environment.
2 .
It may be necessary to put a heat source (light bulb) in
the main control panel to prevent the accumulation of
atmospheric condensate within the panel. The location
and wattage of the heat source is dependent on local
environmental conditions.
3 .
Check the control compartment every two weeks to
confirm that the heat source is functional and is adequate
for current conditions.
Filter Replacement
This unit is provided with filters are show in
. These
filters are disposable and should be replaced periodically.
Unit is equipped with a filter pull to assist in this process. See

Restart
After extended storage, perform a complete start up. Inevitable
accumulations of dirt, insect nests, etc. can contribute to
problems if not cleaned out thoroughly prior to start up. In
addition, thermal cycling tends to loosen mechanical and
electrical connections. Following the startup procedure helps
discover these and other issues that may have developed
during the storage interval.

Fans
The supply, condenser and exhaust fan motors are
permanently lubricated and require no periodic lubrication.
Vibration Levels
Each unit as shipped is trim balanced to operate smoothly. To
provide satisfactory operation after shipping and installation,
use accepted industry guidelines for field balancing fans.
NOTE:
Excessive vibration from any cause contributes to
premature fan and motor bearing failure. Monitor
overall vibration levels every six months of operation.
An increase in levels is an indication of potential
trouble .
Vibration Causes
1 .
Wheel imbalance.
a .
Dirt or debris on wheel blades.
b .
Wheel distorted from overspeed.
2 .
Bent shaft.
3 .
Motor imbalance.
4 .
Fan section not supported evenly on foundation.
Periodic Service and Maintenance
• Check all moving parts for wear every six months.
The Rebel exhaust fans are direct drive variable speed
fan/motor combination, which do not have belts or pulleys
to maintain. The bearings are permanetly sealed and do
not require periodic greasing. The Rebel 3-15 ton units
have similar supply fans. The Rebel 16-28 tons supply
fans have a direct drive motor. These larger motors are
not permanetly sealed and will require greasing every
9000 hours.
