901302 REV E 07/16/19, SLIMLINE COOL PG 6 OF 11
NOTE: THE DRIER IS USUALLY MOUNTED WHERE YOU HAVE ROOM FOR IT.
JUST REMEMBER TO MOUNT IT IN THE COOLEST SPOT POSSIBLE AND
VERTICALLY SO THE SIGHT GLASS IS DIRECTLY ON TOP. (NOT NEXT TO
THE EXHAUST MANIFOLD). IT CAN BE MOUNTED INSIDE THE VEHICLE
AS WELL.
PUSH THE 5/16" I.D. HOSE ONTO THE STRAIGHT #6 FITTING. (SEE HOSE ROUTING ILLUSTRATION ON PG. 7).
INSTALL THE FITTING ONTO THE EXPANSION VALVE (FINGER TIGHT). PUSH THE 1/2" I.D. HOSE ONTO THE
STRAIGHT #10 FITTING, AND INSTALL THE FITTING ONTO THE #10 LINE ON THE EVAPORATOR. (SEE HOSE
ROUTING ILLUSTRATION PG. 7).
AT THIS TIME, TRY TO DETERMINE WHERE YOU WANT YOUR LINES TO GO THRU THE FIREWALL. MOVE THE
HOSES TO THAT POINT. HOLD THE FITTINGS UP TO THEIR RESPECTIVE HOSES, AND DETERMINE IF THE HOSES
WILL CONFORM TO THE LOCATION FOR THE BULKHEAD FITTINGS OR OPTIONAL BULK-HEAD PLATE (VINTAGE
AIR PART# 34215-VUQ OR 34217-VUQ). THE 1/2" HOSE IS HARD TO BEND AT A SHARP ANGLE, AND THE
FITTINGS TAKE UP A CERTAIN AMOUNT OF SPACE.
BEFORE YOU DRILL HOLES IN YOUR FIREWALL MAKE SURE
THAT YOU CAN MAKE THE HOSES FIT WHERE YOU HAVE PLANNED.
THE ENGINE COMPARTMENT APPEARANCE
IS A CONSIDERATION WHEN CHOOSING THIS LOCATION.
WHEN YOU HAVE DECIDED WHERE YOU WANT TO PLACE YOUR BULKHEAD FITTINGS, MARK THESE POINTS
WITH A GREASE PENCIL, AND MAKE A TEMPLATE FROM THE INSIDE LOCATING WHERE THE HOLES WILL BE
CUT WITH THIS TEMPLATE, LOCATE THE SAME POINTS ON THE OUTSIDE OF THE FIREWALL. MARK THESE
POINTS WITH A GREASE PENCIL.
DETERMINE THE BEST LOCATION FOR THE DRIER THAT WILL ALLOW ADEQUATE ROOM FOR THE HOSE AND
FITTINGS THAT CONNECT THE DRIER TO THE BULKHEAD FITTING.
MOUNT THE DRIER. (KEEP THE DRIER CAPPED AS MUCH AS POSSIBLE, IF YOU MUST SCREW THE FITTING TO
THE DRIER, TAPE IT CLOSED).
AT THIS POINT, CUT HOLES FOR BULKHEAD FITTINGS, AND INSTALL THEM.
USING THE HOSE ROUTING ILLUSTRATION AS A GUIDE, ROUTE REMAINING A/C LINES, AND CUT TO
LENGTH.
AT THIS TIME, YOU SHOULD HAVE THE REFRIGERATION HOSES CUT TO THEIR PROPER LENGTH.
PAY CLOSE
ATTENTION TO THE ORIENTATION OF ANY HOSE WITH TWO ANGLED FITTINGS.
ANY HOSE WITH TWO
ANGLED FITTINGS MUST BE MARKED FROM THE HOSE TO THE FITTINGS TO ASSURE THEY WILL REMAIN IN
THIS POSITION AFTER CRIMPING. THE RUBBER HOSE IS ONLY CAPABLE OF A
MINIMAL
AMOUNT OF TWIST
TO AID ALIGNMENT.
REMOVE HOSES AND CRIMP ENDS. IF YOU DO NOT HAVE ACCESS TO THE PROPER EQUIPMENT, VINTAGE AIR
RECOMMENDS TAKING THEM TO A QUALIFIED A/C SERVICE CENTER FOR CRIMPING. (SEE CRIMPING
INSTRUCTIONS SUPPLIED WITH THE HOSE KIT).
WITH THE EVAPORATOR TRIAL FIT COMPLETE, REMOVE THE UNIT AND LOWER INTO THE VEHICLE.
AFTER CRIMPING HOSES, LOCATE THE #6 A/C HOSE WITH THE STRAIGHT FITTING. LUBRICATE A #6 O-RING
AND THE THREADS ON THE FITTING, AND INSTALL ON THE EXPANSION VALVE. TIGHTEN CAREFULLY. REFER
TO FIGURES 3 & 3A, PAGE 8.
LOCATE THE #10 A/C HOSE WITH THE STRAIGHT FITTING. LUBRICATE A #10 O-RING AND THE THREADS ON
THE FITTING, AND INSTALL ON THE #10 LINE OF THE EVAPORATOR. TIGHTEN CAREFULLY. REFER TO
FIGURES 3 & 3A, PAGE 8.
WRAP THE #10 FITTING WITH PRESS TAPE, AND COVER ALL EXPOSED METAL SURFACES. (DO NOT WRAP
THE #6 HOSE, FITTING, OR THE HEATER CORE TUBES). SEE FIGURE 3, PAGE 8.
