Waterco Portapac / Delta Hot
Mounting Instruction (Figure 3)
1. Mark the position for the sensor housing on the wall of the spa approximately 200mm below
the water surface level where there is free water flow.
2. Remove some of the thermal insulation on the rear side of the spa wall to enable access for
sensor housing installation and tightening nut.
3. Drill a 30mm diameter hole in the spa wall.
4. Place the gasket on the sensor housing and insert the housing through the hole in the spa
wall. Place the nut on the housing and tighten.
5. Insert the sensor probe into the housing ensuring it is pushed to the end of the probe well.
The result should look similar to that shown in Figure 3.
NOTE: It may be necessary to secure the sensor in the housing. Avoid placing anything on
the metal part of the temperature sensor as this will affect the accuracy of the readings.
