IMPORTANT NOTICE

These instructions are primarily intended for the use of qualified personnel specifically trained and experienced in the installation of this type of heating equipment and related system components. Installation and service personnel may be required by some states to be licensed. Persons not qualified shall not attempt to install this equipment nor attempt repairs according to these instructions.

MECHANICAL (FOR QUALIFIED SERVICE PERSONNEL ONLY)

PROBLEM	CAUSE		SOLUTION
Harmonics, or whining noise.		U.G.inoperative………………………………	Check movement by putting in hot water (110°F
			or higher). If no movement, replace.
	* Debris or restriction in system………………		Locate the restriction and remove. Flush system
			and clean.
	* Debris in gas line………………………………		Remove debris or blow out gas line.
		Low flow………………………………………	Scale forming in heat exchanger-clean heat
			exchanger and check pool pH and total alkalinity.
Heater going on and off continuously.		Dirty filter………………………………………	Backwash filter.
		Low water level in pool………………………	Raise water level.
		External bypass setting out of
		adjustment…………………………………….	Adjust bypass
	* Pressure switch out of
		adjustment……………………………………..	Adjust pressure switch
Liming or scale forming on heat		Pool water………………………………………	See Water Chemistry page 2.
exchanger.
Sooting		High flow rates…………………………………	Reduce by adding manual bypass valve and
			adjust by putting thermometer in header (1/4”
			NPT) drain opening. Set bypass so thermometer
			reads between 105° and 110°F.
		U.G.Inoperative………………………………	Check movement by putting in hot water (110°
			or higher). If no movement, replace.
	*	Airstarvation……………………………………	Refer to installation instructions.
	*	Improperventing………………………………	Follow recommended installation instructions.
	* Insects or debris clogging
		burner intake ports……………………………	Clean burners.
Pilot outage.		Low gas pressure………………………………	Adjust gas pressure.
		Restricted pilot………………………………..	Clean pilot.
		Weak pilot generator…………………………	Replace pilot.
Yellow lazy flame		Low gas pressure………………………………	Adjust gas pressure.
	* Insects or debris clogging
		burner intake ports……………………………	Clean burners.

Outer jacket very hot	* Broken refractory caused by
(paint blistered)	shipping damage or improper combustion……
	Excessive sooting of heat
	exchanger……………………………………...
Takes long time to heat pool or spa.	Calculate temperature in °/hr…………………

Filter not running long enough………………

Dirty filter………………………………………

Gas line or meter undersized…………………

Replace refractory panels.

Determine cause of sooting & correct. Heat rise (°/hr.) = Heater output Pool gallonage x 8.33

or refer to heater sizing chart.

This does not take into account heat loss due to weather.

Reset time clock. Clean filter.

Refer to installation instructions.

(*Usually occurs on initial start-up)
