(5) Antifreezing tracing belt installation
If the water tank shall inevitably be installed in places with temperature below
0°C, to avoid the pipeline getting frozen due to bad insulation of water system
pipeline, antifreezing tracing belt for pipeline shall be installed in water inlet pipe of
water tank, our pipeline antifreezing tracing belt and its accessories is
recommended, detailed list is as follows:

(6) Stabilizing valve installation
Before connecting water pipe, measure water supply pressure of running water
first, if water pressure is over 0.7MPa, add stabilizing valve in waterway, otherwise,
pressure relief on safety valve might occur when the unit is not heated. Stabilizing
valve (“→” direction shall accord with the water tank direction) shall be installed
between safety valve and filter.
NOTICE!
①
To ensure water safety, the PPR pipe length at the water inlet and outlet is
determined as per the formula: L
≥
70×R
2
, wherein L indicate the pipe length,
and R indicates the inner diameter of the pipe (unit: cm). The pipe should be
insulated properly. No metal pipe is allowed.
②
To ensure safety and reliability, special accessory equipped with this unit
must be adopted (PPR water pipe joint, safety valve and filter etc.). Don't
use the accessory of any third party and replace the accessory by yourself,
any losses thereof for normal operation and usage of heat pump water
heater result from personal injury and improper installation, Gree shall not
