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.

REPLACE AIR FILTER

A DIRTY AIR FILTER REDUCES THE EFFICIENCY OF YOUR VERT-I-PAK AND ALLOWS LINT AND DIRT TO ACCUMULATE ON THE INDOOR-AIR COIL. LINT AND DIRT ON THE INDOOR-AIR COIL CAN DAMAGE YOUR UNIT.

THE AIR FILTER SHOULD BE REPLACED AS IT BECOMES DIRTY. TO REPLACE THE FILTER (CHASSIS MOUNTED RETURN AIR FILTER):

1.SLIDE THE FILTER CLEAR OF THE FILTER RAILS.

2.REMOVE THE FILTER.

3.INSTALL NEW DISPOSABLE FILTER.

NOTE: DO NOT OPERATE YOUR SYSTEM WITHOUT A FILTER IN PLACE OR BLOCK THE FRONT OF THE UNIT RETURN AIR OPENING.

TO REMOVE THE CHASSIS FROM THE CLOSET:

A.SWITCH THE WALL THERMOSTAT OFF.

B.PULL THE POWER DISCONNECT LOCATED IN THE FRONT OF THE CHASSIS.

C.DISCONNECT THE POWER COMING INTO THE UNIT FROM THE MAIN BREAKER PANEL OR THE CLOSET MOUNTED DISCONNECT.

D.DISCONNECT THE ELECTRICAL CONNECTION.

E.DISCONNECT THE DUCT WORK.

F.SLIDE THE CHASSIS OUT OF THE WALL PLENUM.

G.LIFT THE CHASSIS OUT OF THE UTILITY CLOSET.

INSPECT AND CLEAN INDOOR-AIR COIL

EVENTUALLY, MINOR AMOUNTS OF LINT AND DIRT MAY PASS THROUGH THE FILTER AND COLLECT ON THE INDOOR-AIR. THESE MINOR ACCUMULATIONS CAN BE CAREFULLY VACUUMED AWAY WITH A BRUSH ATTACHMENT ON A VACUUM CLANER. CARE MUST BE TAKEN TO AVOID BENDING THE ALUMINUM FINNS ON THE COIL. BENT FINS SHOULD BE STRAIGHTENED USING A SPECIAL FIN TOOL AVALABLE FROM MOST HVAC SUPPLY DEPOTS.

INSPECT OUTDOOR-AIR (OA)INTAKE AND EXHAUST

THE UNIT’S OUTDOOR-AIR INTAKE AND OUTDOOR-AIR EXHAUST PATHS MUST REMAIN CLEAR. CHECK THE OA EXHAUST FREQUENTLY. KEEP IT FREE OF ALL DEBRIS, SNOW, OR ICE. THE OA INTAKE SHOULD ALSO BE KEPT FREE OF OBSTRUCTIONS. BLOCKING THE OA EXHAUST OR OA INTAKE OPENING WILL REDUCE THE EFFICIENCY OF YOUR UNIT AND COULD DAMAGE IT.

INSPECT AND CLEAN CONDENSATE DRAIN

THE CONDENSATE DRAIN MUST BE ROUTED TO A SUITABLE DRAINAGE AREA. CHECK THE UNIT CONDENSATE DRAIN PERIODICALLY. KEEP IT FREE OF ANYTHING THAT MAY BLOCK OR IMPEDE THE FLOW OF CONDENSATE WATER. IF THERE IS ANY ACCUMULATION OF FOREIGN MATTER IN THE DRAIN PIPE, IT SHOULD BE REMOVED AND CLEANED. THE ENTIRE DRAIN LINE MUST BE PROTECTED FROM FREEZING.
