Installation

WARNINGS REGARDING PROPER LOCATION FOR INSTALLATION

WARNING: Do not use the unit in explosive environments or in areas where flammable gas leakage may occur.

WARNING: Do not use the unit in areas where it will be exposed to rain, water or in a corrosive atmosphere.

WARNING: Do not use the unit above 18°C (64.4°F) ~ 45°C (113°F)

WARNING: Do not install the unit on uneven or sloping surface. The unit may roll or topple over even if the casters are set to the locked position.

Moving the Unit

Unlock the casters and push the unit on a flat, level surface and set the caster brakes to the locked position.

Plugging in the Unit

Check the prongs and surface of the power cord plug for dust/dirt. If dust and/or dirt are present, wipe off with a clean, dry cloth.

Check the power cord, plug and prongs for damage or excess play. If any damage or excess play is found, contact a qualified repair technician or a qualified electrician to perform replacement or repair of the power cord, plug or prongs.

WARNING: If the power cord or plug is damaged, repair should only be performed by qualified electrical personnel.

WARNING: Do not connect/disconnect the power cord or attempt to operate buttons with wet hands. This could result in electrical shock.

NOTE: Make sure the AC outlet is free of dirt, dust, oil, water or any other foreign material.

The unit is equipped with an approved NEMA plug configuration (See Specification). The appropriate outlet must be used for each plug type.

Operation

CONTROL PANEL

	7		8	5	6
Figure 7	1	2	3		4

1.POWER BUTTON: Activates unit when POWER BUTTON is pressed. (Fan starts on low speed). If power button is pressed during operation, unit stops.

2.BLOWER BUTTON: Changes fan speed from (Low) to (High) when pressed.

3.SPOT/COOL BUTTON: Activates compressor and begins producing cool air 5 seconds after button is pressed. Regulates temperature based on outlet cool air temperature.

4.ROOM/COOL BUTTON: Activates compressor and produces cool air 5 seconds after button is pressed. Regulates temperature based on inlet ambient air temperature.

5.SET TEMP BUTTONS: Change target temperature/data value by +/- 1. Change data value by +/- 10 by pressing continually. Press the SET TEMP BUTTONS to set temperature. Upper button is to heighten temperature and Lower button is to lower temperature.

6.ALARM: Alarm indicator lights (blinks) and indicates abnormal system operation. If Alarm occurs, compressor stops. System operation stops when ALARM light is activated (blinks) longer than 3 minutes. See alarm code table.

7.CURRENT TEMP: Displays current room temperature in display in Fahrenheit. (In Room Cool Mode only). SPOT/COOL Mode – Displays outlet (cool air) temperature during normal operations. In order to change °F to °C, press SPOT/COOL and ROOM/COOL buttons together for 2 seconds. C will blink 2 times and Figure will change to °C. ALARM codes blink and are displayed when abnormal operation occurs.

8.TARGET TEMP: displays the unit set temperature for ROOM/COOL mode only

OFF-TIMER: Enter to Timer Setting Mode if you press BLOWER Button and SPOT/COOL Button together for 1 second. Press UP/DOWN Button to set the timer until it shows the figure you want to set. After 5 seconds,the figure will be

memorized and the compressor will stop after the time set.

AUTO RESTART: If the unit goes off due to an electrical interruption, the unit will automatically restart when the power resumes.

Maintenance

FILTER CLEANING (See Figures 8 and 9)

There are two filters in the unit. The evaporator filter is located at the front of the unit. The condenser filter is located at the side of the unit.

1.Loosen 2 bolts on the front filter guard.

2.Slide filter up and use a vacuum cleaner to remove the dust from the filter.

3.If the filter is heavily covered with dust and dirt, warm water and mild soap or neutral detergent may be used to wash the filter. Do not use any other chemicals to clean filter, as they will likely damage the filter.

4.Dry the filter in a shaded area before replacing it. Do not operate the unit without the filter installed and the filter guard in the closed position.

5.Replace the clean filter and close the filter guard.

6.To clean the condenser filter, lift up on the side filter from the middle bar slightly and then angle the filter outwards from the bottom and remove.

7.Use the same cleaning procedure as above (3 – 5).

8.To replace the condenser filter, place the top of the filter in the guide and slide the filter up until the bottom of the filter clears the frame. Then push the bottom of filter into the guide and let filter gently fall inside the guide.

NOTE: For effective cooling clean the filter at least every 2 weeks.

- Loosen 2 bolts on the front filter guard. - Slide filter up and use a vacuum cleaner

to remove the dust from the filter.

Removing Filters

Figure 9

Removal of Dust

-Remove dust from the filter using a vacuum cleaner hose attachment.

-If required, wash the filter in lukewarm water with a mild detergent. Leave to dry in shaded area before reinstalling.

SPRING REPLACEMENT (See Figure 10)

Industrial Portable AC

User's Manual

There are two springs on the rear or condensate water tank guide.

1.Release screw on spring hook.

2.Take off spring hook and pull out opposite spring hook from hole in the condensate water tank guide.

3.Replace with a new spring in reverse order.

4.Repeat this cycle for the other spring.

SELF-DIAGNOSTIC CODES (See Table 1)

The alarm light is activated if abnormal operation occurs and a code is displayed on the control panel. The compressor and condenser fan motor will stop operating. The evaporator fan will continue to run for 3 minutes. If the fault is rectified within 3 minutes, the unit will resume operation. If the fault persists for more than 3 minutes, the evaporator fan will stop. The fault must be rectified before the unit will resume normal operation.
