3 Season Model (Rated to 30F)
If your trailer is a 3 season model it will contain the following options:
1. Each waste tank will have a blanket heater in the bottom of the tank. This heater is
thermostatically controlled by a sensor located on the side of the tank. The sensing device
is set to turn on at 35F
and deactivate the heater at 45F. There is also a switch on the
electrical panel in the mechanical room that will also deactivate these heaters, if so desired.
2. Each restroom has a kickspace, electric heater installed at the bottom of the cabinet face.
There is a shut off switch in the mechanical room that will also deactivate these heaters, if
so desired.
3 Season Shower Model (Rated to 30F)
If you have a 3 Seasons shower model, in addition to the 3 Seasons components above,
there will be slight differences in the water heater system. The water heater is on the front
of the trailer and operates in temperatures as low as 30F. The drain options for the water
heater are manual and the unit must be drained before incurring any temperatures below
30F. Please refer to the water heater operating manual for instructions.
Arctic Model (Rated to -20F)
If you have an Arctic model, your unit is equipped with the following heat items to help
keep your unit warm in cold weather. In the mechanical room, there is an LP furnace that
is controlled by a thermostat on the wall. The LP bottles for the furnace are mounted on
the front of the unit and their levels will need to be monitored throughout the rental period.
The furnace is ducted to each restroom and into the mechanical room. The vent into the
mechanical room is adjustable and will need to be adjusted to meet your specific need. The
larger the opening, the warmer the mechanical room and colder the restrooms. The smaller
the opening, then the reverse will be the case. The waste tanks are heated by blanket
heaters on the bottom of the tank. These heaters are thermostatically controlled by a sensor
located on the side of the tank. The sensing device is set to turn on at 35F
and deactivate
the heater at 45F. There is also a switch on the electrical panel in the mechanical room that
will also deactivate these heaters, if so desired.
Arctic Shower Model (Rated to -20F)
If you have an Arctic shower model, in addition to the Arctic components above, there will
be slight differences in the water heater system. The water heater is in the mechanical room
rather than on the front of the trailer. This is to prevent freezing during cold weather and to
allow the addition of some freeze prevention items. These items include two solenoid
valves and a check valve. When the water heater is turned on and the trailer has electrical
current supplied to it...the water heater will monitor itself and circulate warm water if the
temperature is approaching freezing. However, if for some reason power to the trailer is
disrupted, the large brass solenoid will open and the smaller black solenoid will close. The
smaller solenoid will prevent water from entering the water heater and the large brass
solenoid will dump any water in the heater, preventing freeze up. When power is reapplied,
the valve will reopen/close and normal operation can resume. Please note that the solenoid
valves will be warm or even hot to the touch during normal operation. Also, if during start
up the brass valve is leaking water, simply tap the valve with the handle of a screwdriver or
a small plastic mallet, it should seat the valve and stop the water flow. Make certain that the
water heater is plugged into an active source and that the breaker and switch are in the on
position.
