USINg THE REMOTE CONTROL

To  reduce  the  risk  of  fire  or  electric 

shock,  do  not  use  this  unit  with  any 

solid-state speed control device.

The remote control provided with this unit is not 

considered 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. 8B. 

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 Low Speed mode.
To turn the machine off, press the “ON/OFF” button (C) 

Fig. 8A.

This unit has a timer that can be set by remote control.
When the “TIME” button (B) Fig. 8A is pressed on the 

remote control, the machine will run for 1/2 hour. (An 

LED light will show up on the sensor panel (F) Fig. 8B). 

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. 

When the “TIME” button is pressed a third time, the 

machine will run for two hours. At this point, the green 

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.

NOTE: The air cleaner may produce a slight odor for the first few hours of operation due to the protective coating 

which is applied to internal components. This odor will dissipate and should be disregarded.

IMPORTANT: Never operate the air cleaner without air filters in place.

MAINTENANCE

CHANgINg ANd CLEANINg FILTERS

The model 50-875 Type II 3 Speed Ambient Air Cleaner with Pleated Filter 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”.
2.  Remove the outer first stage filter (A) Fig. 9B by lifting and pulling out on the bottom of the filter. Replace the 

first stage filter depending on its condition. When 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.
