SCH Collectors Installation & Operation Manual

Check/control water chemistry

Do not use petroleum-based cleaning 
or sealing compounds in the system. 

 

Damage to elastomer seals and gaskets 
in the system could occur, resulting in 
substantial property damage.

 CAUTION

Test/replace freeze protection fluid

1.  For systems using freeze protection fluids, follow fluid 

manufacturer’s instructions.

2.  Freeze protection fluid must be replaced periodically due 

to degradation of inhibitors over time.  Follow all fluid 
manufacturer’s instructions

.

Freeze protection 

1.  Determine freeze protection fluid quantity using 

system water content, following fluid manufacturer’s 
instructions.  Remember to include expansion tank 
water content.

2.   When using freeze protection fluid with automatic fill, 

install a water meter to monitor water makeup.  Freeze 
protection fluid may leak before the water begins to 
leak, causing concentration to drop, reducing the freeze 
protection level.

3.  The freeze protection set points may be lowered when 

freeze protection fluid is used (see the Lochinvar Solar  
Differential Control Manual).

Glycol

Aqueous solutions of Dowfrost HD fluid are designed to 
provide freeze/burst and corrosion protection, as well as 
efficient heat transfer, in water-based, closed-loop heating 
and air-conditioning systems.

Dowfrost HD fluid has an operating temperature range of 
-50°F to 325°F; with fluid freeze protection to below -60°F 
and system burst protection to below -100°F.  The fluid 
contains corrosion inhibitors that are specially formulated 
for HVAC systems to keep pipes free of corrosion without 
fouling.

Thermal protection

In heated water systems, a warning instruction must be 
provided by the operator near the expansion tank, if persons 
are endangered by excessive surface temperatures.

 WARNING

The expansion tank may be hot, ensure 
scalding does not occur.

 WARNING

Failure to heed these instructions, especially 
the safety instructions, can result in the 
destruction of and defects on the expansion 
tank, endanger persons, and impair the 
operation.

Final checks before starting the system

 

Read the Lochinvar/TiSun Differential Control Installation 
and Operation  Manual to familiarize yourself with 
differential control operation.  Read this manual and follow 
the proper steps to start system.

 

Verify the collector and system are full of water and all 
system components are correctly set for operation.

 

Verify electrical connections are correct and securely 
attached.

 WARNING

A properly sized expansion tank must 
be used to avoid damage to the Solar 
Thermal System.

 WARNING

All piping should be properly insulated to 
avoid freezing and burn potential.

Filling, flushing and bleeding

■ 

There is one fill valve with hose connection for filling, 

 

flushing and draining the solar system on both the safety 

   group and sensor measurement section.

■ 

Connect the pressure hose (forward flow) to the safety 

 

group’s filling connection under the pressure gauge and 

   open fill/flush valve. 

■ 

Connect the flushing hose (return) to the flushing 

   connection on the sensor measuring section and open 
      fill/flush valve. 

■ 

Refer to “Operation, multi-function ball valve and check 

 

valve” on page 38.

■ 

Open the supply ball valve (by turning the red 

 

thermometer handle counter-clockwise until it stops).

■ 

Close return ball valve (by turning the blue thermometer 

 

handle clockwise, until it stops).

■ 

If necessary, the supply and return check valve can be 

  opened by moving the thermometer handles to the 45° 
   position.

■ 

Put sufficient solar liquid in the tank of a filling and 

 

flushing pump (not supplied). The mixing ratio  should be 

 

adapted to local conditions in terms of freeze protection.

■ 

Fill the solar system via the filling and flushing pump and 

   then flush the solar circuit for at least 15 min. to purge all 
 

of the air out of the circuit.

■ 

Close the fill/flush valve (return) with the filling and 

 

flushing pump running and increase the system pressure 

 

to 60 psi. The system pressure can be read at the pressure 

 gauge.

 WARNING

Thermal expansion tanks should be sized 
to account for 1.5 times the solar system 
circuit volume.
