change. When deciding on the location for this
component, the continuous fluctuations in volume/
weight needs to be taken into consideration, as the
volume/weight of the tank will change throughout
the day.
CauTiOn: To ensure the maximum life of the
Solar Loop Expansion Tank do not use a solu-
tion with a higher concentration than 50% v/v
polypropylene glycol. If a higher concentration
is required due to the area in which you live, an
alternative Expansion Tank is suggested with a
diaphragm with a higher concentration rating.
1. Determine the general location for mounting the
Solar Loop Expansion Tank, ensuring that it is a
close as possible to the Solar pumping Station.
!
nOTE: The location, relative to the Solar pump-
ing station, will be dependant on the type of piping
used to connect the tank to the pumping station.
CauTiOn: When installing ensure that no addi-
tional loads are applied to pipelines or equipment.
2. Mark the location of the mounting holes.
3. Drill mounting holes and install wall anchors, if
necessary.
4. Included with the tank is a mounting bracket
(Figure 13) to mount the tank to the wall off of
the floor. Secure the bracket with screws to the
mounting surface.
5. Mount the tank in the bracket, ensuring that the
mounting bracket is located between the two
protruding lines on the tank.
!
nOTE: The tank should be mounted so that the
outlet is at the top for proper operation.
6. Secure the bracket by tightening the gear
clamp on the screw.
7. Connect with piping the Solar Loop Expansion
Tank connection on the Solar Loop pumping
Station (Figure 11J)

Warning: The liquid being collected is high
pressure and high temperature polypropylene
glycol, all associated safety precautions should
be exercised.

Warning: This system is designed to be
used with Polypropylene glycol as a heat
transfer liquid. Substitution of any other
heat-transfer fluid can cause irreparable
damage and create a health and safety haz-
ard.
Warning: The transfer liquid can reach
or exceed temperatures of 60°C/140°F and
poses the risk of scalding.
To ensure maximum heat absorption into the Solar
Water Heat Transfer system it is suggested that a
polypropylene Glycol solution of 50% by volume
with water with liquid inhibitors is used for areas
where the average freezing temperature does not
exceed 30°F (-34°C). Any solution that is used in
the system is recommended to be GRAS compli-
ant. Dimplex offers a polypropylene Solution that is
50% v/v which will be appropriate for most installa-
tions, the MSDS sheet is attached in Appendix 1,
for reference.
!
nOTE: Document the manufacturer and type of
the Solar Heat Transfer solution, because under
certain circumstances, the solar fluid should not be
mixed with agents from other manufacturers.
CauTiOn: To ensure the maximum life of the
Solar Loop Expansion Tank do not use a solu-
tion with a higher concentration than 50% v/v
polypropylene glycol. If a higher concentration
is required due to the area in which you live, an
alternative Expansion Tank is suggested with a
diaphragm with a higher concentration rating.
CauTiOn: Ensure the liquid has an adequate
antifreeze content.
CauTiOn: Freeze tolerance limits are based
