WARNING

Moving parts hazard

TURN OFF ELECTRIC POWER BEFORE SERVICING

THIS COMPONENT.

FAN CAN START AUTOMATICALLY.

FAILURE TO DO SO CAN RESULT IN PROPERTY

DAMAGE, PERSONAL INJURY AND/OR DEATH.

INDOOR AIR FLOW DATA

INDOOR AIR FLOW MAY BE DETERMINED BY MEASURING THE EXTER- NAL STATIC PRESSURE (ESP) OF THE DUCT SYSTEM USING AN INCLINED MANOMETER OR MAGNEHELIC GAUGE, THEN CONSULTING CHART “A” TO DETERMINE ACTUAL AIR FLOW. RATED AIR FLOW FOR EACH UNIT IS OBTAINED AT .10” W.C. WHEN OPERATING WITH A CLEAN FILTER AND A DRY COIL (I.E. HEATING) ON THE INDICATED SPEED AT 230 VOLTS. USE THE AIR FLOW CORRECTION MULTIPLIERS CONTAINED IN CHART “B” TO DETERMINE ACCURATE AIR FLOW UNDER THE LISTED CONDITIONS. UNDER NO CIRCUMSTANCES SHOULD THE VERT-I-PAK EQUIPMENT BE OPERATED AT AN EXTERNAL STATIC PRESSURE IN EXCESS OF .30” W.C. OPERATION OF THE VERT-I-PAK UNDER THESE CONDITIONS WILL RESULT IN INADEQUATE AIR FLOW LEADING TO POOR PERFORMANCE AND/OR PREMATURE COMPONENT FAILURE.

FOR LOW SPEED OPERATION, CONNECT THE FAN OUTPUT TERMINAL FROM THE THERMOSTAT TO THE GL TERMINAL OF THE ELECTRONIC CONTROL. FOR HIGH SPEED OPERATION, CONNECT THE FAN OUTPUT TERMINAL FROM THE THERMOSTAT TO THE GH TERMINAL OF THE ELECTRONIC CONTROL. FOR THERMOSTATS WITH TWO-SPEED FAN CAPABILITIES, CONNECT THE LOW SPEED OUTPUT TO THE GL TERMINAL, AND THE HIGH SPEED OUTPUT TO THE GH TERMINAL.

DETERMINING THE INDOOR CFM: CHART A – CFM

CAUTION

Excessive Weight Hazard

USE TWO OR MORE PEOPLE WHEN INSTALLING

YOUR AIR CONDITIONER.

FAILURE TO SO CAN RESUT IN BACK OR OTHER

INJURY.

CAUTION

Cut/Sever Hazard

SOME EDGES MAY BE SHARP, USE GLOVES

OR OTHER HAND PROTECTION WHEN HANDLING

UNIT.

FAILURE TO DO SO CAN RESULT IN MINOR TO

MODERATE PERSONAL INJURY.

CHASSIS INSTALLATION

INSTALL THE FOLLOWING COMPONENTS

A.ENSURE THAT THE WALL PLENUM IS INSTALLED IN ACCORDANCE WITH THE INSTRUCTIONS LISTED ON PAGES 6-10.

B.PLACE THE CHASSIS INTO THE CLOSET WITH THE OUTDOOR SIDE FACING THE WALL PLENUM OPENING.

C.SLIDE THE CHASSIS INTO THE WALL PLENUM UNTIL THE PLENUM DIVIDER SEAL IS ESTABLISHED. (SEE FIGURE 13)

FIGURE 13

CHASSIS INSTALLATION/

INSTALLED VIEW

THE VERT-I-PAK CHASSIS MUST BE INSERTED INTO THE WALL PLENUM SO THAT THE PLENUM DIVIDER GASKET MAKES CONTACT WITH THE PLASTIC CONDENSER BAFFLE ON THE UNIT. THE CHASSIS WILL FIT APPROXIMATELY 2 ⅜" INTO THE WALL PLENUM.
