These air conditioners were designed to operate from a '
I 15 VAC, 60H2, 1 Phase power supply. Anytime an air
conditioner is not operating properly, the power supply should
be examined by a qualified technician to verify that the air
conditioner is receiving the proper power supply.
The ability of the air conditioner to maintain the desired inside
temperature depends on the heat gain ofthe recreational
vehicle.
The size of the vehicle, amount of window area, amount of
insulation, direct exposure to the sun, outside temperature and
the number of people in the recreational vehicle may increase
the heat gain to such an extent that the capacity ofthe air
conditioner is exceeded.
As a general rule, air entering the air conditioner will be
cooled about 15 to 20 degrees, depending on the outside
temperature and humidity conditions.
For example, if the air entering the return air grilles in the air
conditioner is 80 degrees F., the air leaving the discharge
grilles in the air conditioner will be 60 to 65 degrees F.
As long as this temperature difference is being maintained
between the return air and discharge air, the air conditioner is
operating at its capacity. If the desired inside temperature
(normally 80 degrees F) cannot be maintained, then the heat
gain of the RV is too great for the capacity of the air
conditioner.
Parking the vehicle in a shaded area, keeping windows and
doors shut and avoiding the use ofheat producing appliances
in the vehicle will help to reduce the heat gain. When
possible, the addition ofinsulation and tinted glass (especially
in uninsulated vans) should be considered.
NOTE
The optional Elect-A-Heat heating assembly is intended to
take the chill out of the indoor air when the air is a fet
degrees too cool for comfort. The heating assembll. is an
effective "chill chaser". It is not a substitute for a furnace.
R410A Roof Top Air Conditioners
High Pressure Switch Lockout Circuit
Air conditioners and heat pumps using R410A refi:igerau
utilize a factory installed High Pressure Switch Safel.C:rcuit.
In the event of an abnormal condition (failure of fan mct.'r.
dirty condenser coil, dirty filters), the high pressure stit:h
will prevent the compressor from continuing to run. On.-e the
high pressure switch has tripped, this safety circuit *ill -Lock
Out" the compressor preventing it flom trying to restan or run
until the I 15 VAC supply power has been turned off and then
back on to reset the High Pressure Switch Safety Circuit. If
repeated trips ofthe high pressure switch lock out occur. then
you must have the unit serviced by a qualified technician.
II. CONTROL PANEL
Ifyour RV air conditioner is operated from the control panel
located in the ceiling assembly, then there are three controls
on the ceiling assembly that help you control the air
conditioner. They are as follows:
A. The Selector Switch * The selector switch determines
which mode of operation the air conditioner will be
in. By rotating the selector switch, the operator can
obtain any system function desired. System
functions vary depending upon options of both the
roof top unit and ceiling assembly. Figure I shows
selector switch location and lists all available
functions by model.
The "Operation" section explains the operational
characteristics of each mode of operation.
The Thermostat (temperature control) - In the
cooling mode, the thermostat regulates the "ON"
and "OFF" temperature setting at which the
compressor will operate.
For "Heat/Cool" models, the thermostat also controls
the "ON" and "OFF" temperature settings of the
heater assembly (See Figure 1).
Louvers - The louvers are located at both ends ofthe
ceiling assembly shroud and are used in directing the
discharge air from the unit.

I.
A
For Cooling (Refer to Figure 1, page 3).
Turn the selector switch to the "LOW COOL" or
"HIGH COOL" position.
Rotate the thermostat (temperature control) to the
position that is the most comfortable to you. The
thermostat will turn the compressor on when the
temperature of the air entering the air conditioner
rises a few degrees above the setting you have
selected. Then the temperature of the air entering
continues to cycle the compressor on and off in the
above mentioned fashion until the selector switch is
turned to another mode of operation.
Position the louvers to the desired direction the
discharge air is to flow.
Note: The fan operation is constant, only the
compressor cycles on the thermostat.
II. Operation During Cooler Nights (Cooling
Operation).
It is important, when the outdoor temperature drops in the
evening or during the night to below 75 degrees F., that the
thermostat (temperature control) be set at a midpoint between
"Warmer" and "Cooler". If the setting is at "Cooler", the
evaporator coil may become iced-up and stop cooling. During
the day when the temperatures have risen above 75 degrees F.,
reset the thermostat switch to the desired setting.
NOTE
Should icing-up occur, it is necessary to let the cooling
(evaporator) coil defrost before normal cooling operation is
resumed. During this time, operate the unit in the "HIGH
FAN" position with the system at maximum air flow. When
increased or full air flow is observed, the cooling coil should
be clear of ice.
B.

III. Short Cycling
When an air conditioner is in operation, its compressor
circulates refrigerant under high pressure. Once off, it will
take two to three minutes for this high pressure to equalize.
The air conditioning compressor is unable to start against high
pressure. Theiefore, once the air conditioner is turned off, it is
important to leave it off for two to three minutes before
restarting.
Short cyciing the compressor (or starting it before pressures
have equalized), will in some instances, kick the circuit
breaker or overload.
IV. For Heating ("Elect-A-Heat" Ceiling Assembly
Model Only) Refer to Figure I' page 3).
The optional Elect-A-Fleat heating assembly is intended to
take the chill out of the indoor air when the air is a few
degrees too cooi for comfort. The heating assembly is an
effective "chill chaser". trt is not a substitute for a furnace.
Do not expect the heating coil on your heater to glow.
Because the fan draws in cold air and f,orces it over the coil,
the coil will not turn red. A hint of red may occur where the
moving air does not directly touch the coil.
A. Turn the selector srvitch to the "LOW HEAT"
position. At "LOW HEAT", the fan operates on
low speed with heat output at maximum.
B. Rotate the thermostat (temperafure control) su'itch
to the position that is the most comfortable to you.
The thermostat will turn the heater on when the
temperature of the air entering the air conditioning
unit drops below this setting a few degrees and
automatically turns off when the temperature of the
air entering the air conditioner rises a few degrees
above this setting. The heater wiil continue to cycle
on and off in this fashion until the selector switch is
tumed to another mode of operation.
C. Position the louvers to the desired direction the
discharge air is to flow.
Discharge air temperature can be controiled to some
extent by opening or closing the louvers.
When the louvers are closed, the warmest localized
discharge air is achieved. Fully opened louvers rvil1
throw the warm discharge air to the back and front of
the vehicle for more efficient circulation and faster
warn-up. Although the air temperarure is lorl'er rvith
the louvers fully opened, the heating capacitf is still
the same.
V. For Air Circulation Only (Refer to Figure 1.
page 3).

IV. MAINTENANCE
I. Owner
One of the biggest advantages to your new Coleman-Mach air
conditioner is that the maintenance needed to keep the unit in
good care is minimal. In fact about the only thing you. the
owner, must take care of is the cleaning and replacement of
the filters.
Filters are made from long life non-atrlergenic natural fibers
which can be cleaned and reused, and which completely filter
the circulated air when the air conditioner is in operation' If
the filters are not cleaned at regular intervals, they may
become partially clogged with lint. dirt, grease, etc. A
clogged filter will produce a loss of air volume and may
eventually cause an icing-up ofthe cooling (evaporator) coil.
IMPORTA.\T
Do not operate your air conditioner for ertended periods
of time without the filter installed.
An even more serious condition occurs rvhen the air
conditioner is operated without a filter. When this
happens the lint, grease, etc. that are normalll-stopped b1'
the filter are now accumulating in the cooling coil. This
not only leads to a loss of air volume and a possible icing-
up ofthe cooling coil, but could also result in serious
damage to the operating components of the air
conditioner.
We retommend that the filters be cleaned and changed at
least every two weeks when the air conditioner is in
operation.
4

Cleaning and/or changing the filters:
1. Disengage the two ll4 -tum fasteners that secure the
ceiling assembly grille to the ceiling assembly (See
Figure 2).
2. Lower the grille and filters from the ceiling assembly.
3. Take filters out and either clean or exchange with
other filters (See Figure 2).
4. If the vehicle is equipped with a flush mount ceiling
assembly, remove the four return air grille screws.
Remove filter from grille and either clean or "
exchange with new filters.
NOTE
If replacement filters are necessary, the filters can be
purchased from most Airxcel, Inc. Authorized Service
Centers. It is recommended that spare filters be carried with
the RV at all times to replace worn, torn or deteriorated filters.

Service Person
Electrical - All electrical work and/or inspection
should be performed only by qualified service
personnel. Contact your nearest Airxcel, Inc.
Service Center if electrical problems should arise.
Check Points - Failure to start or to cool the air are
sometimes problems with air conditioning units.
The Coleman-Mach RV air conditioner is designed
to operate on 115 volt electrical power. If the
compressor on the air conditioner fails to start, check
with your Airxcel, Inc. Service Center to determine
C.
that the proper wire size is connected to the unit, the
proper circuit breakers are installed as protection
devices on the electrical circuit and the proper sized
extension cord is being used for the distance covered
from the utility outlet to the RV. The required
minimum wire size is #12 AWG for lengths up to
25 feet (larger wire size for greater distances). Each
air conditioning unit must be protected with a 20
amp time delay fuse or circuit breaker.
If the air conditioner continues to trip off the circuit
breakers, have an electrician check the starting
amperage and running amperage on the unit. If
the circuit breaker continues to trip off and the
electrical consumption is found to be normal, it will
require the replacement of the faulty circuit breaker.
If all electrical power to the air conditioner is normal
but neither the fan or the compressor will operate,
the connector piug located behind the ceiling
assembly control box should be checked to
determine whether it is faulty.
On the heating-cooling air conditioner models, if all
electrical power to the unit is normal and the fan
runs but you never get any heated air, then the
electrical plug to the heating unit should be checked
for a secure corinection. Ifthis does not ccrrect the
malfunction, the heating thermostat or limit switch
may be faulty.
Mechanical Integrity - The air condrtioner should be
inspected periodicaiiy to be sure that the bolts which
secure the unit to the roofare tight and in good
shape. Also, an examination of the plastic shroud
covering the air conciitioner on the top of the roof
should be made periodically" Be sure the four
mounting screws and washers are snug and holding
the shroud to the air conditioner. Also examine the
shroud to be sure it is not developing cracks or has
suffered damage from impact.
Lubrication
DANGER
DISCONNECT THE POWER SUPPLY TO THE TINIT
BEFORE SERVICING TO PREVENT A SHOCK
HAZARD OR POSSIBLE INJTIRY FROM MOVING
PARTS.
The blower drive motor on some units may include oiling
cups at the top of the motor. There is no requirement to
oil the journals under normal operating conditions.
However, if lubrication to the unit is desired, use only SAE
20 non-detergent fype oil. DO NOT OVER OIL - three to
four drops in each oil hole onee a year if sufficient.

I. RENSEIGNEMENTS GENERAUX
Ces climatiseurs de toit furent congus pour fonctiorurer d partir
d'une source d'alimentation de I 15 V.c.a., 60 Hz, I phase.
Lorsqu'un climatiseur ne fonctionne pas correctement,
I'alimentation dlectrique doit 6tre examin6e par un technicien
qualifi6 afin de v6rifier que le clirnatiseur regoit la bonne
alimentation de courant.
La capacitl du climatiseur de maintenir la temp6rature
int6rieure voulue d6pend du gain de chaleur du v6hicule
rdcreatif. La taille du v6hicule, le nombre de fen6tres, la
quantitd d'isolant, I'exposition directe au soleil, la temperature
ext6rieure ainsi que le nombre de personnes dans le v6hicule
peuvent tellement augmenter la chaleur que la capacit6 du
climatiseur est ddpass6e.
En regle gendrale, l'air qui entre dans le climatiseur sera
refroidi d'environ 15 a 20 degrds selon la temp€rature et
I'humiditd de I'exterieur.
Par exemple, si I'air qui entre dans les griiles d'entr6e d'air du
climatiseur est de 80 degrds F. (24 degrds C), l'air quittant les
grilles de sortie d'air du climatiseur sera de 60 d 65 degrds F.
(13 a 16 degr6s C).
Aussi longtemps que cette diff6rence de temperature est
maintenue entre l'entrde et la sortie d'air, le climatiseur
fonctionne 2r sa capacitd. Si l'on ne peut conserver la
temp6rature int6rieure voulue (normalement 80 degr6s F.
(24 degr6s C)), alors le gain de chaleur du VR est trop 6lev6
pour la capacit6 du climatiseur.
Le fait de stationer le vdhicule.d l'ombre, de garder les
fen6tres et les portes fermdes et d'dviter d'utiliser des
II. PANNEAU
Si votre climatiseur de VR fonctionne d partir d'un panneau de
contr6le au plafond, il y a alors trois commandes au plafond
pour aider ir contr6ler le climatiseur. Les voici :
A. Le selecteur - le sdlecteur determine le mode de
fonctionnement du climatiseur. En le tournant,
l'operateur peut obtenir toutes les fonctions du
systdme voulues. Celles-ci variant selon ies options
de I'unitd du toit et du plafond. Le figure I
illustrents l'emplacement du sdlecteur et 6numerents

appareils d6gageant de la chaleur aidera d r6duire le gain de
chaleur. On peut aussi considdrer ajouter de f isolant et des
verres teint6s (tout particulidrement dans les caravans non-
isol6es).
REMARQUE
Le montage de chauffage Elect-A-Heat optionnel est congu
pour enlever l'air froid ir l'int6rieur du v6hicule un peu
trop frais pour le confort. Le systime de chauffage est
efficace pour <enlever le froiil> mais non pas pour
remplacer l'appareil de chauffage.
Climatiseurs de toit R410A
Circuit de blocage du contacteur haute pression
Les climatiseurS et les thermopompes au frigorigdne R410A
comportent un circuit de s0ret6 du contacteur haute pression,
installd en usine. Dans I'dventualitd d'une anomalie (une
d6faillance du moteur du ventilateur, un serpentin de
condensation sale, des filters encrasses), le contacteur haute
pression empdche le compresseur de rester en marche. Quand
le contacteur haute pression est d6clench6, ce circuit de s0ret6
bloque le compresseur, ce qui emp6che ce dernier de
red6marrer ou de fonctionner jusqu'd ce que I'alirnentation de
1 15 V c.a. soit coup6e puis retablie de fagon d rdinitialiser le
circuit de sfiret6 du contacteur haute pression. Si le blocage
du contacteur haute pression se d6clenche ir maintes reprises,
vous devez faire rdparer l'appareil par un technician
comp6tent.
DE CONTNoTN
La section <fonctionnement> explique les
caract6ristiques de fonctionnement de chaque mode.
B. Le thermostat (contr6le de temperature - sous le
mode de refroidissement, le thermostat contr6le le
r6glage de temp6rature <ON> (marche) et <OFF>
(arr6t) du chauffage.
Pour les modeles <chaleur/refroidissement>. le
thermostat contr6le aussi les r6glages de temperafure
<ON> et (OFF) du radiateur. Voir figure 1 d la page
J.

C. A6rateurs - les a6rateurs se trouvent aux deux
extr6mites du couvercle du plafond et servent ddiriger la ddcharge d'air de I'appareil.
III. FONCTIONNEMENT
I. Pour le refroidissement (se reporter aux figure 1,
page 3).
A. Placer le s6lecteur d la position (LOW COOLD
(refroidissement faible) ou d <HIGH COOL)
(refroidissement fort).
B. Tournez le thermostat (r6gulateur de temp6rature) sur
la position qui vous convient le mieux. Le thermostat
enclenchera le compresseur aussitot que la
temp6rature de 1'air entrant dans le climatiseur
s'dldvera d un ou deux degr6s au-dessus du r6glage
s6lectionn6. Ensuite, le compresseur continuera de
s'enclencher et de s'arr6ter en fonction de la
temp6rature de l'air entrant dans le climatiseur
jusqu'ir ce que vous mettiez le sdlecteur sur un autre
mode de fonctionaement.
C. Placer les a6rateurs dans la direction voulue pour
l'dcoulement de 1'air ddchargd.
Remarque: Le ventilateur marche toujours de faEon
6gaie, seul le compresseur effectue des cycles en
fonction du thermostat.
il. Fonctionnement durant les nuits plus froides
(fonctionnement de refroidissement)
Lorsque, le soir ou la nuit, la temp6rature ext6rieure tombe en
dessous de 24 "C, il est important que le thermostat (le
r6gulateur de temp6rature) soit mis au milieu des positions
< Warmer > et < Cooler >. Si le thermostat est plac6 sur
< Cooler >, le serpentin 6vaporateur peut se recouwir de givre
et, par cons6quent, cesser de refroidir l'air. Lejour, lorsque la
temp6rature remonte au-dessus de 24 oC, remettez le
thermostat ir la position d6sir6e.
REMARQUE
S'ii y a de la glace qui s'accumule, il est alors ndcessaire de
laisser le serpentin du refroidisseur (6vaporateur) d6geler
avant de reprendre le fonctionnement de refroidissement
normal. Durant ce temps, faire fonctionner l'appareil en
position ( HIGH FAN ) (ventilateur fort) avec le systdme au
maximum de la circulation d'air. Lorsque cette circulation
augmente ou fonctionne au maximum, le serpentin du
refroidisseur ne devrait pas avoir de glace.
III. Fonctionnement en courts cycles
Lorsqu'un climatiseur fonctionne, son compresseur fait
circuler le r6frig6rant sous haute pression. Arret6, il faut deux
ir trois minutes pour que cette haute pression s'6ga1ise.
Le compresseur du climatiseur est incapable de d6marrer
contre une haute pression, donc, lorsque le climatiseur est
arr6te, il est important de la laisser arrCter pendant deux i trois
minutes avant de le faire red6marrer.
Les compresseurs fonctionnant en courts cycles (ou lanc6s
avant que les pressions ne soient 6galis6es) d6clencheront
parfois le disjoncteur ou une surcharge.
IV. Pour chauffer (modile de plafond <<Elect-A-Ileab>
seulement), se reporter aux figure 1, page 3.
Le montage de chauffage Elect-A-Heat optionnel est congu
pour enlever l'air ffais d l'intdrieur du v6hicule, un peu trop
froid pour le confort. Le systdme de chauffage est effrcace
pour <enlever le froid>, mais non pas pour remplacer
l'appareil de chauffage.
Ne pas s'attendre d ce que le serpentin de chauffage de votre
appareil de chauffage produise de l'incandesence. Puisque le
ventilateur aspire de l'air fioid et le fait passer sur le serpentin,
lorsque l'air passe directement sur le serpentin.
A. Placer le sdlecteur a (LOW HEAT)) (faible chaleur)
et le ventilateur fonctionne ir vitesse r6duite avec la
sortie de chaleur au maximum.
B. Faire tourner le thermostat (contr6le de temperature)
d la position la plus confortable. Le thermostat met
le compresseur en marche lorsque la temp6rature de
l'air qui entre dans le climatiseur diminue de
quelques degr6s sous le r6glage choisi. Lorsque la
temp6rature de l'air qui entre dans le climatiseur
augmente au-dessus de ce r6glage, il arrCtera le
compresseur. Le chauffage continuera ir passer de
marche d arr6t de la manidre indiqu6e pr6c6demment
jusqu'ir ce que le sdlecteur soit plac6 dans un autre
mode de fonctionnement.
C. Placer les a6rateurs dans la direction voulue pour
l'dcoulement de l'air ddchargd.
La temp6rature de d6charge d'air peut 6tre
contr6l6ejusqu'a un certain point en ouvrant ou
en fermant les a6rateurs.
Lorsque les adrateurs sont fermds, l'on peut atteindre
l'air de ddcharge le plus chaud. Les adrateurs
entidrement ouverts ddchargeront l'air chaud vers
l'arridre et l'avant du vdhicule pour une circulation
plus efficace et un r6chauffement plus rapide. Bien
que la temp6rafure de l'air soit moins 6levde lorsque
les a6rateurs sont entidrement ouverts, la capacit6 de
chauffage sera encore la m6me.

IV. ENTRETIEN
I. Propri6taire
Un des plus grands avantages de votre nouveau climatiseur de
Coleman-Mach est que 1'entretien n6cessaire pour conserver
votre appareil en bon 6tat est minime. En fait, tout ce que
vous avez d faire, corrme propri6taire, est de nettoyer et de
remplacer les filtres.
Les filtres sont fabriqu6s de fibres naturelles non-allergdnes de
longue durde que l'on peut nettoyer et rdutiliser, et ils filtrent
entidrement l'air circuld lorsque le climatiseur est en marche.
Si les filtres ne sont pas nettoy6s ir intervalles r6guliers, ils
peuvent se bloquer partiellement par de la poussidre, de la
graisse, de la peluche, etc. Un filter bloqu6 provoquera une
perte de volume d'air et peut dventuellement causer
l'accumulation de glace sur le serpentin du refroidisseur
(6vaporateur).
IMPORTANT
Ne pas faire fonctionner votre clirnatiseur pendant le
longues p6riodes sans filtre.
Lorsque le climatiseur fonctionne sans filtre, il peut y avoir
un problime plus grave car la poussiire, la graisse, la
peluche, etc. arr6t6es normalement par le filtre
s'accumulent maintenant dans le serpentin du
refroidisseurr. Ceci provoque une perte de volume d'air et
une accumulation possible de glace sur le serpentin du
refroidisseur, mais cela peut aussi provoquer de graves
dommages aux composants du climatiseur.
Nous recommandons de netfoyer ou de changer les filtres
au moins aux deux semaines lorsque le climatiseur
fonctionne.

II. Responsable de l'entretien
A. Electricit6 - Tous les travaux etlou inspections
electriques ne doivent 6tre effectu6s que par un
personnel d'entretien qualifie. Contactez votre cenffe
d'entretien Airxcel, Inc. s'il y a des problemes.
B. Points de contr6le - Les climatiseurs ont quelquefois
des probldmes de d6marrage ou de refroidissement.
Le climatiseur Coleman-Mach est congu pour
fonctiorurer sur un courant electrique de I 15 V. Au
cas oi le compresseur de climatiseur refuserait de
ddmarrer, contacter le centre d'entretien Airxcel, Inc.
pour d6terminer si le climatiseur est aliment6 par un
cdblage de calibre ad6quate, si 1a protection du circuit
6lectrique est assur6e par des disjoncteurs appropri6s
et si le calibre du cdble de rallonge, raccordant la
prise de secteur du v6hicule, est aussi ad6quat.
Jusqu'd 7,6 m, le calibre minimum de fil requis est
1,5 mm (#12 AWG). Un calibre plus fort est requis
pour une distance plus longue. Chaque climatiseur
doit 6tre prot6ge par un fusible d action differ6e ou
par un disjoncteur.
Si le climatiseur fait d6clencher continuellement le
disjoncteur, faire verifier par un 6lectricien
l'amp6rage de d6marrage et de marche . Si le
d6clenchement du disjoncteur se poursuit alors que la
consommation 6lectrique reste normale, il sera
necessaire de remplacer le disjoncteur ddfectueux.
Si, alors que l'alimentation dlectrique du climatiseur
est normale, ni le ventilateur ni le compresseur ne
fonctionne, v6rifier la connexion de la prise situ6e d
l'arridre de la boite de commande du module.

Pour les moddles de climatiseur d air chaud et ir air
froid, si tout le courant dlectrique d l'appareil est
normal et si le ventilateur fonctionne, mais sans air
chaud, alors, il faut vdrifier l'unitd de chauffage pour
s'assurer d'une bonne connexion. Si ceci ne corrige
pas la parure, il se peut que le probldme r6side avec le
thermostat de chauffage ou le disjoncteur.
Int6grit6 m6canique - Le climatiseur devrait Etre
inspecte rdgulidrement pour s'assurer que les
boulons qui retiennent l'appareil au toit sont serrds et
en bon 6tat. Il serait aussi utile de faire un examen du
couvercle de plastique couvrant le climatiseur sur le
toit. S'assurer que les quatre vis de montage"et les
rondelles sont bien en place et retiennent le couvercle
au climatiseur. Examiner aussi le couvercle s'assurer
qu'il n'y a aucune fissure ou de dommages suite i un
