The Manufacturer gives only general guidelines
for Generator reauirements. These Generator
requirements come from experience consumers
have with our equipment in field applications.
When sizing Generators, the total electrical
power consumption of the Caravan must be
considered.
Keep in mind that Generators lose
power because of altitude increases above sea
level, high outside temperatures, and lack of
maintenance.
NOTE:
Some authorities require that this appliance be
installed only by an authorized electrician.
2. PRECAUTIONS FOR

LOCATION
This air conditioner is designed for installation
and use on the roof of a Caravan. One or
more
units
may be used on the vehicle.
Consider the van’s size, roof structure, and
cooling
requirements
when determining your
needs.
A.
DESIGN RECOMMENDATIONS
For one unit
installation:
The
Air
Conditioner
should be mounted slightly
forward of center (front to back) and
centered from side to side on the van.
(FIG.
3.A.l)
For two unit installation$ Install one Air
Conditioner l/3 and one Air conditioner
2/3’s back from front of van and centered
from side to side. (FIG. 3.A.2)
L = Length
- s-

B.
Many air conditioners can be installed at
existing
roof vent openings.
These
openings may be larger or smaller than 355
X 355 mm and will need modification.

4.
Be sure your roof structure is capable
of supporting a weight of 65 Kg
when the
van is in
motion.
(Normally if the roof can support a
static load of approximately 100 Kg it
meets this requirement.) (FIG. 3.C.4)

the van. FAILURE TO FOLLOW THIS
INSTRUCTION MAY CREATE A
HAZARD. (FIG. 4)
2. Check on the roof to be sure no
obstructions are in the area where
the air conditioner will be installed.
3.
Check inside where the

by installing
2.
If the opening is smaller than 350 X
350 mm, it will be necessary to
enlarge the opening; see 4.B.
3.
Route a grounded power supply line
from circuit breaker or fuse box to
the roof opening. (FIG. 4.C.3)
a.
The power supply must be a
separate circuit, fused with a 20
amp Time Delay Fuse or 20 amp
Circuit Breaker.
b. The power supply
must be
grounded 2.5 mm2 COPPER sup-
ply for distances of 7.5m or
less.
C.
The power supply wiring MUST
comply with
all
applicable
regulations and wiring codes.
d.
Depending on entrance location,
up to l/2 meter of supply wire
must extend
into the roof
opening to insure
ease of
attachment to the air
conditioner.
e.
If vent fan was removed, the
existing wire may be utilized,
provided it is of proper size and
properlv fused.

Framing is required around the roof
opening to insure adequate support,
provide a smooth surface for sealing
and prevent hot or cold air from
being drawn into the opening.
This

framing should be wood strips 380 X
25 mm X thickness of roof to ceiling
distance. A hole for the power supply
must be provided, FIG. 4.C.4.
