PLUMBING CONNECTIONS
The Turbotemp heater has the unique
capability of direct schedule 40
PVC plumbing connections. A set of
bulkhead fittings is included with the
Turbotemp to insure conformity with
Waterco’s recommended PVC plumbing
procedure. Other plumbing connections
can be used. See Figure 3 for plumbing
connections.
Before operating the heater on a new installation, turn on the circulation pump and
bleed all the air from the filter using the air relief valve on top of the filter. Water should
flow freely through the heater. Do not operate the heater unless water in the pool/spa
is at the proper level. If a manual by-pass is installed, temporarily close it to insure that
all air is purged from the heater.
!
CAUTION
VALVES
When any equipment is located below the surface of the pool or spa, valves should be placed
in the circulation piping system to isolate the equipment from the pool or spa. Check valves
are recommended to prevent back-siphoning. Backsiphoning is most likely to occur when
the pump stops, creating a pressure-suction differential. Do NOT sanitize the pool by putting
chlorine tablets or sticks into the skimmer(s). When the pump is off, this will cause a high
concentration of chlorine to enter the heater, which could cause corrosion damage to the heat
exchanger.
Exercise care when installing chemical feeders so as to not allow back siphoning
of chemical into the heater, filters or pump. When chemical feeders are installed in
the circulation of the piping system, make sure the feeder outlet line is down stream
of the heater, and is equipped with a positive seal noncorrosive “Check Valve”, (P/N
R172288), between the feeder and heater.
!
CAUTION
MANUAL BY-PASS
( WATER FLOW RATE)
Where the water flow rate exceeds the maximum 454 LPM, a manual
bypass should be installed and adjusted. After installing the valve,
adjust the valve to bring the flow rate within the acceptable range.
Then remove the valve handle or lock it in place to avoid tampering.
See Figure 4.
