Figure 2. Installation Clearances
• When installed in areas where freezing temperatures
can be encountered, drain the water circuit to
prevent possible freeze-up damage. Refer to "Freeze
Protection" on page 34 for proper procedures.
• When the heater is located below the water line of the
pool or spa, it may be necessary to adjust the Water
Pressure Switch (WPS) to compensate for the no-
flow static head (see Figure 4). If after adjusting the
WPS to its maximum setting without resolution, an
external Water Flow Switch (WFS) must be installed.
See "Water Flow Switch" section below for further
installation instructions.
• For high-wind installation requirements, refer to
Figure 5 – depending on the model size.
Figure 3. Base Design - Handling
NOTE: The base is designed with recessed areas to allow
the use of hand trucks or lifting without the possibility of
pinching ngers as shown in Figure 3.
Water Flow Switch
If the heater is located below the water line of the pool, an
external Water Flow Switch (WFS) must be installed. The
WFS is provided with the heater and must be installed as
per the following instructions to prevent nuisance heater
tripping (for example: high-pressure switch fault) and to
ensure proper operation.
1. Install the WFS onto the water inlet piping as shown
in Figure 65.
2. The WFS must be installed before any bypass or
check valve assembly.
3. The WFS must be installed within a straight,
horizontal piece of inlet piping of at least 5" in length.
The WFS sensor is sized for 1.5" pipe, but can be
converted to 2" if required.
4. The WFS must be installed in close proximity to the
heater, Raypak recommends to install no further
than 2 ft. per Figure 65.
5. Connect the WFS per the wiring instructions located
on page 85.
