Isotemp Slim water heater has been designed and produced to ensure that your water heater will
give long and trouble free operation for many years.
It is important, however, that your Isotemp water heater is correctly installed and maintained. During
the winter period when the unit is not being used, it is essential that it is drained to avoid risk of dam -
age due to freezing.
Every single Isotemp water heater is individually pressure tested prior to delivery and carries a 2
year factory warranty in respect of defects in material and/or manufacture and a limited 5 year war-
ranty on the inner tank.

Slim Square 16L water heater

Installation:
1. Placement:
The water heater may be positioned in a suitable place with the engine water connectors on
the water heater below the level of the engine header tank. The connection hoses between the engine and
the water heater should be kept as short as possible and placed with as little level differences as possible to
keep flow losses on a reasonable level. Long hoses also result in heat losses. The water heater is to be
placed in such a way, that the thermostat, heater element and safety valve are easily accessible for service.
These components and all water connections are placed on the water heater front gable.
2. Mounting:
The water heater can be mounted horizontal, vertical or leaning with the safety valve with its
drainage valve as the lowest point, safely fastened in its mounting brackets. (See fig. 1) The mounting brack-
ets can be turned to fit the bottom or a bulkhead on board. Bear in mind the extra weight of the unit, when full
of water.
