sensor chip and mounting post, and note the sensor
mounting hole on the block for later reassembly.
Handle the sensor chip with care! It is not necessary to
disconnect the sensor cable from the controller board.
When you are finished cleaning the heat block, set the
block back in place. Once the block is back in place,
reposition the sensor assembly chip and mounting
post back in its original location on the heat block and
push down to snap the sensor post back into position.
The following tools are required for disassembling
the unit:
Philips screwdriver
Flat blade screwdriver
∕
⅜ in. and
15
in. sockets and driver
16
Cleaning cloths
To disassemble the unit
1. Unplug unit.
2. Unplug the power cord from the socket at the base of
the unit. Remove pump hose at quick-disconnect.
3. Remove HAF filter.
4. Remove the four cover bolts (Fig. D) from the Cover
then lift off.
5. Lift the heat exchange block straight up off the base.
Note orientation of block for reassembly.
Inspect the heat exchange block carefully. Use a
vacuum to gently clear the channels of the block. Take
care not to damage the block.
Vacuum or use compressed air on both sides of the
upright condenser coil until it is clean. We recommend
the use of a HEPA vacuum. Take care not to bend or
damage the fins.
NOTICE: Dri-Eaz Coil Cleaner (Dri-Eaz part no. S402)
may be used on the horizontal evaporator (cold) coil
only. Follow instructions on product label. Take care
ABOUT HAF FILTERS
Dri-Eaz dehumidifiers are designed to be used with High Airflow Filters from 3M. HAF filters allow for maximum airflow,
provide superior particle retention, and resist microbial growth on filter surfaces. To ensure maximum protection for
equipment, technicians, and the job site, follow these HAF filter guidelines:
Replace the HAF filter whenever it has been vacuumed clean and reused three times. HAF filters lose their effectiveness after
three uses.
Replace the HAF filter whenever it has been used on a mold remediation job or otherwise exposed to potentially dangerous
contaminants. Continued use of a contaminated filter risks the spread of contamination.
Do not wash or apply any liquids to the HAF filter. Exposure to liquids will reduce the effectiveness of the electrostatic material.
Do not operate without the HAF filter in place. Do not operate the unit with any other filter type. Incorrect filtration will reduce
unit efficiency and can cause damage to the unit.
Do not operate the unit when excessive dust or airborne particles are present. The high volumes of particulates present during
sanding, spray painting, or similar operations can clog the unit and cause damage.
not to spray or wipe Coil Cleaner on or near any
electrical components or sensors.
To reassemble the unit
1. Reinstall the heat exchange block. Make sure to
position it in the original orientation and be sure to reseat
the heat exchange block fully into the sheet metal baffle
over the evaporator coil (Fig. D). When properly
installed, the top of the block will be level with the top of
the condenser coil.
2. Now slide the top cover straight down into place.
3. Install and tighten the front two cover bolts. After they
are tight, install and tighten the two rear cover bolts.
NOTICE: Foam strips are attached to the front and
rear edges of the evaporator coil to provide an airtight
seal against the heat exchange block. When
reinstalling the block, make sure the seals are in place
and are not kinked or folded.
Foam gaskets are also attached to the inside top edges
of the cover. Before reinstalling the cover, make sure the
gaskets are in place and straight.
CLEANING AND SERVICING THE PUMP
To access the pump, remove the Cover. Then remove
the four Rear Panel Bolts and the five base plate bolts
(Fig. D). Now remove the Rear Panel. It is not necessary
to disconnect the wire harness from the rear panel or
from the electrical box. For easier access to the pump,
lay the panel its back.
Wipe out the pump basin with a clean, dry cloth.
To reassemble, follow the above steps in reverse. Be
sure all cables are properly routed and take care to
thread drain hose back into the sump liner. Take care
not to cross-thread or over-tighten the bolts.
