Product Introduction
A. Purpose
HOUGHTON BELAIRE is designed to provide a comfortable environment inside a recreational vehicle or caravan.
B. How to provide an efficient operation
Many factors will affect the total heat load within the caravan and many factors can also affect the working efficiency
of the air-conditioner. Before purchasing HOUGHTON BELAIRE, the user shall consult with the caravan manufacturer to
understand the total heat load of the caravan and to choose the correct air-conditioner for the application.
The following measures are very useful to reduce the heat load within a caravan or RV and improve the performance
of the air-conditioner.
Close all the doors, skylights and windows, draw the curtains and open the sunshade.
Adjust the caravan’s position to make sure the sunshade is on the southern side in the northern hemisphere or on the
northern side in the southern hemisphere. This will reduce the exposure to direct sunshine.
Turn off the unnecessary electrical appliances within the caravan to reduce the heat-load.
Please cook outside of the caravan.
Park the caravan at a shade place.
In case of exceptional high temperature, turn on the air-conditioner in advance during the morning.
Adjust the set temperature of the remote control to prevent from frequent start or stop of the unit.
C. Condensation
For the areas where the air humidity is comparatively low, when the warm moist air within the caravan meets with the
cold wind from the outlet, condensate water may be caused, which is also called as “sweating”. In this case, make sure the
following measures are taken:
Close all the doors, skylights, windows and draw the curtains to reduce the warm moist air incoming.
In the operation of the air-conditioner, a large number of condensate water will be produced on the roof as the warm
moist air is exhausted by the operation of the air-conditioner. The size of the condensate water is decided by the air
humidity. In this case, do not adjust the wind FAN to low or auto mode but adjust it to high FAN mode to increase the
circulation of the air and reduce the condensation degree.
Please be noted that losses caused by the condensate water are not within warranty scope.
D. Choosing and using of generator
HOUGHTON BELAIRE requires an AC power source,and may require for generator driving in some remote areas.
Requirements for generator include: efficient power source, stable currency, output waveform: sine wave, that shall
meet the driving requirements of the compressor. The user shall consult with the generator supply and fully refer to
their suggestions.
Please be noted that losses caused to the product by the using of the generator are not within warranty scope.
