Unit Storage - Daikin Rebel Applied DPSA Installation And Start-Up Manual

Unit Storage

Location
The Daikin Rooftop Packaged System Unit is an outdoor
unit. However, the 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. The condenser fins are particularly
vulnerable to damage by even light contact with objects.
• Make sure all doors are securely closed.
• If isolation dampers are provided, verify that they are
properly installed and fully closed to prevent the entry
of animals and debris through the supply and return air
openings.
• Units without isolation dampers should be fitted with
covers over the supply and return air openings.
Preparation
Supply (and Return) Fans
1. Turn the supply and return fan manual motor protectors
(MMP) to the OFF position.
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 climatic conditions, condensate
may collect on components inside the unit. To prevent
surface rust and discoloration, spray all bare metal parts
with a rust preventive compound, and consider adding
a desiccant inside of the cabinet and control panel.
Pay close attention to fan shafts, 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.

Cooling Circuits
The steps below are necessary only if the unit has been
started.
1. Turn the compressor manual motor protectors (MMP) to
the OFF position.
2. Close the discharge and liquid line refrigerant service
valves on each circuit.
3. Tag the valves as a warning for the technician who
restarts the units.
Gas Furnace
LOCKOUT/TAGOUT all power sources If the unit is equipped
with a gas furnace and close the gas shutoff valve.
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.
3. The location and wattage of the heat source is
dependent on local environmental conditions.
4. Check the control compartment every two weeks to
check that the heat source is functional and is adequate
for current conditions.
