PLUMBING FOR WATER CONNECTIONS LOCATION

The VERSA heater requires water flow and posi- tive pressure to fire and operate properly. It must therefore be installed downstream of the discharge side of the filter pump. A typical installation is plumbed as follows:

1.The inlet side of the filter is plumbed directly to the discharge side of the filter pump:

2.The outlet side of the filter is then plumbed to the inlet of the heater; and

3.The outlet of the heater is plumbed to the return line to the spa. The pump, filter and

heater are thus plumbed in series. Plumbing from the heater back to the spa must not

have any valves or restriction that could prevent flow when the pump is operating. To do so will void the warranty.

Heater must be located so that any water leaks will not damage the structure of adjacent area. High temperature plastic pipe (CPVC) may be connected directly into the heater if local codes permit.

FLOW RATES

PIPE SIZE: 1 1/4"-1 1/2" MIN.GPM: 20, MAX.GPM: 60*

*When flow rates exceed 60 GPM an external auxil- iary bypass valve is required. See External auxiliary bypass valve section for details.

COMPANION FLANGE CONNECTIONS

The inlet/outlet header flange accepts a 1 1/2" copper tube or 1 1/4" galvanized pipe as a slip connec- tion directly into the manifold. The flange is also threaded for 1 1/2" pipe thread. 1-1/2" CPVC adapters (when available) can also be used.

DO NOT use petroleum base assembly fluids (such as Petroleum Jelly or lubricating oil). If assembly lube is required, use a silicone base compound, such as Amoral, etc.

CAUTION: Never install PVC directly in header flanges. The initial connection must be made with a higher temperature material such as CPVC or Copper. PVC may be utilized immediately after the initial connection.

AUTOMATIC CHLORINATORS AND CHEMICAL FEEDERS

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).

Chlorinators must feed downstream of the heater and have an anti-siphoning device to prevent chemical back-up into the heater when the pump is shut off.

NOTE: High chemical concentration 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.

UNITHERM GOVERNOR OPERATION

The patented Unitherm Governor is a thermostatic mixing valve specifically designed to maintain constant heater internal temperature between 105° - 115°F de- spite continually changing flow rates 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.
