SINCLAIR
(5) Installing antifreezing tracing belt
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:
Self - limiting temperature tracing belt
Pipeline antifreezing tracing belt installation statement sheet
Caution：
To ensure water safety, the PPR pipe length at the water inlet and outlet is determined as per the
①
formula: L≥70×R
pipe (unit: cm). The pipe should be insulated properly. No metal pipe is allowed.
To ensure safety and reliability, special accessory equipped with this unit must be adopted (PPR
②
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,Sinclair shall not be liable.
5.3 Thermal Insulation Measures
5.3.1 Thermal Insulation for the Refrigerant Pipes
5.3.1.1 Thermal Insulation Materials
Use closed-cell foam thermal insulation materials with flame retardant grade of B1.
The heat conductivity is not greater than 0.035 W/(m·k) when the average temperature is 0°C.
5.3.1.2 Thickness of the Thermal Insulation Layer
Outside Diameter of the Pipe (mm)
Thickness of the Thermal Insulation Layer (mm)
Use sunblock, anti-weathering, and non-cracking thermal insulation materials for outdoor pipes.
5.3.1.3 Procedure of Insulation
(1) Select thermal insulation materials based on design requirements.
(2) Wear the thermal insulation sleeve before connecting refrigerant pipes. Users cannot cut the
thermal insulation material apart and then wrap up with ties after connecting the pipes by
welding.
(3) Specifications of the thermal insulation sleeve must match with that of the refrigerant pipes.
(4) Reserve a distance of about 200 mm near the welding point to protect the thermal insulation
sleeve during welding. After performing the air-tightness test, perform thermal insulation to the
welding point separately to ensure continuity of the thermal insulation sleeve.
(5) The thermal insulation layer cannot crack during construction. Bond the thermal insulation
material joints with special glue and then wrap them with electrical adhesive tape. The width of
the adhesive tape must be 50 mm or greater to ensure secure connection.
(6) Use glue to bond the thermal insulation material at the water outlet to the unit to prevent
dewing.
