Plumbing up the system:

This system will work if the pump draws or discharges water through the heater. Minimum water flow required is 25 GPM. Minimum
plumbing size required is 1.5 inch. This system is equipped with M7 Technology (no pressure switch). There are dual sensors installed
on the heater to measure the water temperature flowing through the heater. No need to mount any sensors or flow switches. The heater has
standard 2.0 inch plumbing fittings. If the spa plumbing is 1.5 inch, use reducers to connect to the heater 2.0 inch heater tailpieces. If re-
plumbing is necessary, use PVC Glue with primer to connect the plumbing. When installing an In-Line Filter System, either install it
before the heat pump and controller or after the heat pump and controller. Never install the filter system in between the heat pump and
controller. Make sure to create a water flow bypass plumbing around the filter for sufficient water flow. For systems installed near or
above the water level, and more than 5 feet from the tub, install the In-Line Filter System after the heat pump and controller with a water
flow bypass plumbing. A water flow bypass plumbing allows half the water to go through the filter and half the water to go around the
filter. This way water flow is not restricted. We recommend NSF rated flexible PVC for simpler connections. Go to this link for more
