ATTENTION:
FAILURE TO READ AND COMPLY WITH ALL WARNINGS, CAUTIONS AND INSTRUCTIONS PRIOR TO
STARTING INSTALLATION MAY CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE AND
VOID WARRANTY.
This device must be installed in accordance with Equipment Manufacturer’s instructions and in
accordance with all applicable local codes,including plumbing, drainage and electrical.
“Branch circuit protection shall be provided using a Listed branch circuit protection device rated minimum
250V AC/100V DC, maximum 1A as appropriate for the supply source”
(To ensure proper performance of product, instructions must be followed.)
1.
Disconnect (and lock-out, if required) all power to the M-Series, P-Series, S-Series or CITY MULTI
Indoor Unit at the Disconnect Switch (if installed) or at the main disconnect panel serving the indoor
and/or outdoor unit.
2.
Connect DPLS2 Splice Connector to the selected mating Wire Harness Connector – see wiring harness
selection
(Table 1). Connect the Control Box’s Splice Connector to the mating connector on the Wire Harness (Fig 1).

Fig 1 Fig 2: Typical indoor unit with cover removed
Typical Installation - example: Wall Mount Indoor Unit – MS/MSY/MSZ/PKA/PKFY:
1.
Remove front cover of indoor unit in order to expose the coil and the control circuit area of the unit (Fig 2).
The disassemblyof the front cover, air lters, and possibly electrical shields will vary according to style of
indoor unit installed. See the Mitsubishi Electric’s Technical Manual for detailed disassembly and details.
2.
Locate the corresponding connector (see Table 1) on the printed control circuit board and, remove the connector of the thermistor (Fig 4). Plug female connector of the Wire Harness into the printed circuit board,
and plug the male
connector on the opposite end into the thermistor connector (Fig 5).
Fig 3 Fig 4 Fig 5 Fig 6
3.
Connect black/red power input wire to indoor unit power supply terminal (S1, S2).
4.
Determine the best location for the DPLS2 Control Box (above the drain pan and outside of the main
airow):
Using the double-sided adhesive pad, mount the Control Box in a location inside the indoor unit that will
allow clearance for the cover to be reassembled (Fig 6).
5.
Reassemble all covers that were removed during the installation.
6.
Test the DPLS2:
Reconnect power to the indoor unit. Use extreme caution, beware of high voltage on the indoor unit
during testing. Turn unit on and set cooling thermostat to lowest temperature setting. Make sure to
restore power to the outdoor unit before performing the test in step 7.
Using a clip lead or other metallic object, carefully make a connection between the two pins on the
Micro Sensor (Fig 7). Indoor unit should shut down after a 5-10 second delay.
8.
Disconnect indoor unit power before proceeding to the next step.
9.
Determine the best location for the DPLS2 Micro Sensor. Make sure that power has been disconnected.
Find the drain pan below the coil in the indoor unit. It is located directly below the aluminum ns of the coil
and is slightly wider than the coil depending on the style of indoor unit.
10.
Wipe all water, dirt and dust from the drain pan with a damp cloth. Temporarily locate the Micro Sensor in the
drain pan.
11.
Slide pan clip with sensor onto the front edge of the drain pan (Fig 8). Push the sensor down into the pan
to a position where the two sensing tips remain above the condensate level in normal operation, ensure the
Micro Sensor touches the bottom of the trough and the panel clips are pushed all the way down on the front
edge of the trough (Fig 9).
(These installation instructions are typical for all wall mounted, oor standing, ceiling recessed, and ceiling
concealed, and ceiling suspended units. Location of the micro sensor should at the drain pan no less than
3/8” from the bottom.)
12.
If there is no place for pan clip attach the sensor to the coil clip (there are two optional coil clips: 7mm and
5mm).
Clip the coil clip onto the evaporator coil. Insert the coil clip between tins or at the coil U-bend. Position the
wires up and senor pins down. Adjust sensor height by moving the vertical member (with sensor attached)
up and down. Sensor pins should be coated above normal condensate level, while below the condensate
overow level. (Fig 10)
13.
Temporarily reassemble the front cover of the indoor unit to make sure that it reattaches properly. If there
is interference with the front cover, relocate the Micro Sensor on the drain pan and recheck clearances.
14.
Once the best location has been determined, remove the double-sided tape on the Micro Sensor and reinstall it
in the same manner as described above. Ensure the Micro Sensor does not touch the bottom of the drain pan
and the panel clips are pushed all the way down on the front edge of the trough (Fig 9).
15.
Bundle and tie wrap excess wire. Locate and anchor the excess wire bundles so that they do not
interfere with the reassembly of the cover of the Indoor Unit.
