Waterco Portapac / Delta Hot
INSTALLATION REQUIREMENTS
• Ensure the Portapac has adequate ventilation to avoid overheating. Allow minimum 100mm
free space behind the motor fan cowl for free airflow to cool the motor. If the pump is
enclosed, ensure the enclosure has adequate ventilation ports to enable the hot air to
escape.
• Ensure Portapac is accessible for maintenance purposes and thermostat temperature
adjustment on top of the pump (where fitted).
• Ensure Portapac is located in a position which is NOT prone to flooding.
• The installation must comply to relevant electrical standards and local authority rules.
Contact your electricity supply company for further information on electrical requirements.
• The external temperature sensor MUST be installed to ensure accurate and reliable operation,
refer to “Installing the Temperature Sensor” on page 5 of this manual.
Hydraulic Layout
When connecting the Portapac to the spa hydraulic system the following instructions must be
followed:
1. Connect the pipe to the PVC half unions supplied with the pump.
2. Use minimum size 40mm pipe or larger for both suction and return hydraulic lines.
3. Portapac must be securely fixed to an adequate support to prevent vibration and stress on
hydraulic lines.
4. Pipe supports must be installed to reduce load on the equipment and excess stress on the
hydraulic lines.
5. Install Portapac below water level as it is NOT a self priming pump. Install suction hydraulic
line without high points to prevent trapped air.
6. Minimise the use of bends (elbows) and fittings where possible.
7. The Portapac must be connected to at least two (2) separate suction points in the spa
via a common line, no less than 600mm apart. Check local codes for correct installation
requirements.
8. The spa suction points (pump suction hydraulic line) should be located as far below the
water level as possible to prevent the pump from running dry. Spa jets (return hydraulic line)
should be located well below the water level.
9. If the pump is installed below water level, shut off valves (either Waterco diverter or ball
valves) should be installed on both the suction and discharge piping to prevent back flow of
pool water during routine servicing of the pump and other circulation equipment.
