The source of he shock mus be quickly s opped, by ei her shu ing off he power or removing he vic im. If he power
canno be shu off, he wire should be cu wi h an non-conduc ive ool, such as a wood-handle axe or hickly insula ed
cable cu ers. Rescuers should wear insula ed gloves and safe y glasses, and avoid looking a wires being cu . The
ensuing flash can cause burns and blindness.
If he vic im mus be removed from a live circui , pull he vic im away wi h a non-conduc ive ma erial. Use wood, rope,
a bel or coa o pull or push he vic im away from he curren . DO NOT TOUCH he vic im. You will receive a shock from
curren flowing hrough he vic im’s body. Af er separa ing he vic im from power source, immedia ely check for signs
of a pulse and respira ion. If no pulse is presen , s ar CPR (cardio pulmonary resusci a ion). If a pulse is presen ,
respira ion migh be res ored by using mou h- o-mou h resusci a ion. Call for emergency medical assis ance.

Important Installation Notes
Safety Precautions
• See “Safe y Precau ions” beginning on page 5 prior o ins alling and servicing his produc .
Evaporator Location
NNoottee:: Refer to the illustrations on the following pages.
• Bes airflow is achieved when evapora or is ins alled an equal dis ance from each side wall.
• I is recommended ha moving bulkheads no be allowed closer han 1219 mm (48.00 in.) or 1 palle from
evapora or ou le ((DDee aaiill AA)).
• Minimum clearance from bo om of evapora or o op of cargo should be 101 mm (4.00 in.) ((DDee aaiill AA)).
NNoottee:: This minimum clearance is required under the fan intake area only and does not refer to the LL AADD LLIINNEE.
• Evapora or should be loca ed a minimum of 51 mm (2.00 in.) from ruck wall ((DDee aaiill BB)).
Defrost Drains
NNoottee:: Refer to the illustrations on the following pages.
• Evapora or mus be properly moun ed o provide a slope owards he drain. This is accomplished by adding one 3/8
in. and one 3/16 in. washers on he drain side and only one 3/8 in. washer on he o her side a each moun ing
surface.
• Defros drains mus exi he evapora or a a 45° angle. Drains should be 267 mm (10.50 in.) from he evapora or o
he ruck ceiling ((DDee aaiill CC)).
Wall Drain Tube
NNoottee:: Refer to the illustrations on the following pages.
• CPVC
• 1.00 in. ID (In ernal Diame er)
Refrigerant Tubing and Electrical Wiring
NNoottee:: Refer to the illustrations on the following pages.
• I is impor an o minimize he amoun of ime he refrigera ion ubes are uncapped and open o ambien condi ions.
Always keep ubes capped un il ready o connec and solder.
• Check ubes and copper fi ings for obs ruc ions prior o assembly.
• I is also required ha ni rogen or ano her iner gas be used o purge he ubes while soldering. This preven s
oxida ion and forma ion of scale inside ubes.
• Use 35% silver solder for joining all remo e refrigeran ubes.
• Insula e suc ion and ho gas lines.
• All refrigera ion ubes should be secured by clamps every 600 mm (24.00 in.).
• All elec rical harness should be secured by clamps or ie bands every 600 mm (24.00 in.).
• Only one rough (W = Wall and C = Ceiling) is required ((DDee aaiill DD && EE)).
• All dual evapora or ins alla ions require wo suc ion ubes.

Defrost Drain Tube onnectors
IImmppoorrttaanntt:: Follow the instructions below to prevent defrost drain tube water leaks.
All S-3 remo e evapora ors are equipped wi h a quick disconnec fi ing ha connec s he drain pan o he drain ubes
((DDee aaiill II)).
To properly ins all he ube make sure ha he ube is fully inser ed pas he O-ring and up o he s op inside he coupler
((DDee aaiill IIII)).
IImmppoorrttaanntt:: The fitting will grip the tube before it seals with the o-ring.
When he ube is in he correc posi ion he O-ring will seal and he Tee h will grip he ube keeping i in place. Check he
fi by pulling on he ube(s) o insure ha i will no pull ou of he fi ing ((DDee aaiill IIIIII)).
To disconnec he ube from he fi ing: press he colle in o he fi ing. Hold he collec in place and pull he ube ou .
The fi ing can be re-used. Clean any burrs off he ube before re-inser ing i in o he fi ing ((DDee aaiill IIVV)).
