INSTALLATION REQUIREMENTS
Prior to starting the installation, first read the
ENTIRE "Installation” section of this manual. Since
the cleaning unit (with empty waste tank and
accessories) weighs approximately 770 lbs.
(860 lbs. if mounted on water tank), consider the
following recommendations before installing this
unit.
1. The unit should NOT be mounted in any motor
vehicle of less than 1/2 ton capacity, or 3/4 ton
if equipped with one or more auxiliary fresh
water tanks.
The console with waste tank and accessories
must NOT exceed the vehicle's axle weight limit.
2. If mounting in a trailer, make certain that the
trailer is rated for the total weight of the UNIT
AND TRAILER. Electric or hydraulic brakes
should be provided, and a strict compliance with
any State and Federal vehicle laws must be
maintained.
3. The vehicle tires should have a load rating
above the combined vehicle and unit weight.
4. We do not recommend using flooring materials
that absorb water. This could result in rust and
corrosion of the vehicle floor.
5. Padding under rubber floor mats should be
removed before installing this unit.
6. We highly recommend using a galvanized drip
tray under the console (Part #86050370, PRV
NO. 56-501845, or Part #86050380, PRV NO.
56-501930 for units mounted on a water tank.)
7. If using a trailer, the console should be
positioned so that it balances properly with
respect to the axle. Ten percent (10%) of the
overall unit weight (without accessories or water)
should be on the tongue.
FUEL REQUIREMENTS
Use unleaded gasoline ONLY. DO NOT use any
gasoline additives. We recommend the use of clean,
fresh, unleaded gasoline intended for automotive
use. High octane gasoline should NOT be used with
the engine on this unit.
ENGINE OIL REQUIREMENTS
Use high quality detergent oil of at least API
(American Petroleum Institute) service class SF or
SG. Select the viscosity based on the air
temperature at the time of operation as shown in the
following table. NOTE: Using less than service
class SF or SG oil or extending oil change intervals
longer than recommended can cause engine
damage.
