AUTOMATICCHLORINATORSANDCHEMICALFEED- ERS

All chemicals must be introduced and completely diluted into the pool or spa water before being circulated through the heater. Do not place chlorine tablets or bromine sticks in the skimmer. High chemical concen- trations will result when the pump is not running (i.e. overnight).

Chlorinatorsmustfeeddownstreamoftheheaterand have an anti-siphoning device to prevent chemical back- up into the heater when the pump is shut off.

NOTE: High chemical concentrates from feeders and chlorinators that are out of adjustment will cause very rapid corrosion to the heat exchanger in the heaters. Such damage is not covered under the warranty.

UNITHERMGOVERNOROPERATION

The patented Unitherm Governor is a thermostatic mixing valve specifically designed to maintain constant heater internal temperature between 105°F to 115°F despite continually changing flow rated from the filter and changing pool temperatures. This narrow range is needed to prevent damaging condensation on the burn- ers which will occur if the heater runs for any length of time below 100°F. It is also needed to inhibit scale formation in the tubes by maintaining temperatures well below accelerated scaling temperatures.

EXTERNAL AUXILIARY BYPASS VALVE (Where Required)

An auxiliary bypass valve should be used when flow rates exceed 115 GPM (usually a high performance pump size larger than two HP will exceed this flow rate). This valve is required to complement the function of the automatic bypass valve, particularly when starting the heater in winter or early spring when the spa or pool temperature is down below 55°F. It also serves to eliminate needless pressure drop through the heat and accompanying reduction in the flow rate to the spa jets, etcetera.

To set bypass: with clean filter, adjustment is made by feeling the inlet and outlet pipes at the heater. Outlet pipesshouldbeslightlywarmerthaninletandcomfortable to the touch. If pipe is hot, close bypass; if cold open bypass.

The heater is also equipped with a manual bypass built into the header. This is in addition to the automatic bypass valve. This may be used with flow rates up to 120 GPM and adjusted as below.

NOTE: Sooting or liming caused by improper bypass adjustment voids the warranty
