INST 448 Jacuzzi® JVX Series Pool pump V10-17
Use with Jacuzzi® J-HN Series Gas Heaters
Gas heaters (and electric heat pumps) generally rely on a water pressure switch to activate the heater control
circuit. When the Jacuzzi® JVX Series Pool pump operates on low speed the water pressure produced in generally
insufficient to activate the pressure switch and control circuit within the heater.
If using a compatible Jacuzzi® J-HN Series Gas Heater you can automatically increase the speed of your Jacuzzi®
JVX160 or JVX300 Pool Pump to ensure the water pressure switch is activated and the heater obtains enough
water flow to operate correctly.
A RJ12 (6 wire flat cable) specifically wired and obtained from Jacuzzi® will connect your pump and heater.
Refer to Heater Instruction Manual for data cable connection details.

WARNING:
DO NOT open the strainer pot if the pump fails to prime, or if the pump has been operating without water in the
strainer pot. Pumps operated in these circumstances may experience a buildup of vapour pressure and may contain
scalding hot water. Opening the pump may cause serious personal injury. In order to avoid the possibility of personal
injury, make sure the suction and discharge valves are open and the strainer pot temperature is cool to touch, then open
with extreme caution.
THIS FILTER OPERATES UNDER HIGH PRESSURE
When any part of the circulating system (e.g, lock ring, pump, filter, valves, etc) are serviced, air can enter the system and
become pressurized. Pressurized air can cause the lid to blow off which can result in server injury, death or property
damage. To avoid this potential hazard, follow these instructions carefully.
CAUTION: To prevent damage to the pump and filter and for proper operation of the system, clean the pump
strainer and skimmer baskets regularly
THE PUMP STRAINER BASKET
The pump strainer basket, sometimes referred as the “hair and lint pot” is the unit in front of the volute. Inside the chamber
is the basket which must be kept clean of leaves and debris at all times. View the basket through the “see through lid” to
inspect for leaves.
Regardless of the length of time between filter cleaning, it is most important to visually inspect the hair and lint pot basket at
least once a week. A dirty basket will reduce the efficiency of the filter and heater and also put am abnormal stress on the
pump motor which could result in a costly repair bill.
