shock, do not use this unit with any
solid-state speed control device.

The remote control provided with this unit is not con-
sidered a solid-state device.

The Air Cleaner is equipped with a REMOTE CONTROL
(A) Fig.8A.

NOTE: The remote requires two (2) AAA batteries (not
supplied). The Battery housing is located underneath the
back cover.

Notice that the remote control has three control buttons
(Fig. 8A): TIME (B), ON/OFF (C), and SPEED (D). These
buttons correspond to the LED sensor panel on the rear
of the machine (K) Fig. 10B.

NOTE: When the machine is connected to the power
source, a green light (E) will be activated on the panel.

To activate the blower unit, press the “ON/OFF” button
(C) Fig. 8A. The machine will begin in the default speed
of Low or “L” on the sensor panel. Press the SPEED
button once, and the machine will run at the high (or “H”
level). Press the SPEED button again, and the machine
will run at the medium speed (or “M”). Press the SPEED
button a third time, and the machine will return to the

Pressing the “TIME” button again will set the machine to
run for one hour. Notice that the light on the sensor
panel has now moved to the 1H location (G) Fig. 8B.

light will show up under the two hour location (H). When
you press the “TIME” button the fourth time, the unit will
run for four hours. Notice that the indicator light (J)
glows at the four hour mark.

All of these functions can be manually controlled by
using the two buttons on the sensor panel (K) Fig. 8B.

OPERATION

CHANGING AND CLEANING FILTERS

The model 50-875 Air Cleaner has an “air flow” indicator (A) Fig. 9A located on the left side of the unit. To check the
filters, turn the unit “ON”. If the indicator points to “green” (B) Fig. 9A, the filters are clean. Clean (or change) the filters
when the indicator points to “red” (C) Fig. 9A as follows:
1.

Turn the unit “OFF”.

Remove the outer first stage filter (A) Fig. 9B by lifting and pulling out on the bottom of the filter. Clean or replace
the first stage filter depending on its condition. Clean this filter in one of two ways: Use a shop vac to remove the
dust, or use compressed air (30 psi maximum) to blow the dust out of the filter. If you replace the outer filter, check
to see if the filter has an air flow arrow (A) Fig 9D. If so, point the arrow inward. If the filter does not have an air
flow arrow, install the filter either way.
