DANGER
CAUTION

Unit Storage

Location
The Maverick II is an outdoor unit. However, the construction
schedule may dictate storage either on the ground or in its
final position at the site. If the unit is stored on the ground,
additional precautions should be taken as follows:
• Make sure that the unit is well supported along the length
of the base rail.
• Make sure that the unit is level (no twists or uneven
ground surface).
• Provide proper drainage around the unit to prevent
flooding of the equipment.
• Provide adequate protection from vandalism, mechanical
contact, etc.
• Make sure all doors are securely closed and all latches
closed.
• Units should be fitted with covers over the supply and
return air openings.
Preparation for Storage
Supply Fans
1 . Remove the drive belts, tag them with the fan name and
unit serial number, and store them in a conditioned space
out of direct sunlight.
2 . Once every two weeks, rotate the fan and motor shafts.
Mark the shaft positions first to make sure they stop in a
different position.
3 . 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. Pay close attention to
fan shafts, sheaves, bearings, and bearing supports.
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 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
adequatefor current conditions.
