1.After power has been connected to unit, fans will start in either preset (high/low) speed selection.

2.Air velocity is controlled by selection of high or low speed indicator. This feature allows the setting of air velocity to individual desired performance and energy efficiency.

3.Air direction at outlet can be controlled by adjustable vanes at the nozzle which compensates for possible draft conditions.

Figure 6 - Desired Air Flow Adjustment for Temperature and Humidity Control.

Operation

NOTE: Air direction settings shown in Figures 6 & 7.

NOTE: Cold air will try to escape near floor level. Warm air will try to penetrate curtain near top of doorway. Air flow can be controlled by direction of nozzle louvers and by high/low settings.

4.For multiple unit applications (wide openings), mount units a minimum of 3” apart to allow for proper air intake and discharge.

Maintenance

WARNING: ALL ELECTRIC POWER MUST BE DISCONNECTED WHEN INSTALLING OR SERVICING THIS EQUIPMENT. MORE THAN ONE DISCONNECT SWITCH MAY BE REQUIRED TO REMOVE POWER FROM THE UNIT.

LUBRICATION

Ball bearings are permanently lubricated and require no further lubrication.

CLEANING

1.The air door cabinet may be wiped off with a damp cloth. Do not allow motor to get wet. Do not use sol- vents or harsh detergents.

NOTE: Keep air intake louvers clear of dirt and dust accumulation which could affect performance.

2.Check blower wheels for accumulated dirt twice a year and clean. If disassembly is required, see GENERAL SERVICING section.

GENERAL SERVICING

WARNING: IF SERVICING IS REQUIRED, IT SHOULD BE DONE BY QUALIFIED PERSONS ONLY.

WARNING: ALWAYS DISCONNECT POWER SUPPLY BEFORE SERVICING.

1.To remove motor/blower heater assembly, repeat Steps 4, 5 and 6 in Unpacking section.

2.Place motor/blower assembly on workbench.

3.To replace blower wheel, remove the three slotted hex head screws on outer blower ring assembly (See Figure 8, Replacement Parts Illustration.) The wheel is held onto shaft by two hex head screws.

NOTE: To re-assemble repeat steps 4 & 5 in installation section page 3.

IMPORTANT: NOTE POSITION OR WHEELS TO PREVENT RUBBING WHEN REPLACED.

4.To remove motor:

a.Remove blower wheels. (See Step 3 above.)

b.Remove blower scrolI (six hex head screws).

c.Unscrew and remove motor mounts.

5.Replace motor/blower assembly
