Installation
Water supply pipe
Evaporator piping:
• Clean out all cold water piping.
• Connect the evaporator piping.
• Exhaust the air in the cold water system at the highest point of this system piping.
• Install pressure meters, temperature meters and valves at the inlet piping and outlet piping.
• Install strainer at the inlet piping of evaporator, mesh number of the strainer screen shall be
equal to or more than 40 meshes.
• Install balance valve and flow switch at the outlet.
For installation positions of each typical accessory on water supply piping of the water chiller, please
refer to Figure 4. Piping assembly may be changed depending on positions of joint and water supply. For
installation diagram of typical system piping, please refer to Figure 5.
CAUTION
• Water the pressure of the evaporator shall not be more than 0.5MPa (i.e. maximum operation
pressure) to avoid damage of the parts at the cold water side of the water chiller.
• The return water temperature of heating shall not be set more than 40
℃
; otherwise, the
compressor will not be exchanged as per the Three Guarantees.
• Before the final piping connection of the water chiller, all external water supply piping
systems shall be washed thoroughly. Any impurity mixed in the piping system is strictly
forbidden; otherwise, we will assume no liability for any consequence so incurred.
NOTICE:
If commercial acidic cleaning agent is used, a temporary bypass tube shall be set at the side
of the water chiller for prevention of damage to evaporator. Please do not use untreated or
improperly treated system water supply to avoid damage to machine.
CAUTION
• To avoid damaging the water chiller, the piping for system water shall not be fitted reversely.
The water inlet tube must be connected to the inlet connector indicated by "water inlet". The
water outlet tube must be connected to the outlet connector indicated by "water outlet".
• Exhaust valve shall be set at the highest point of the piping, in order to exhaust the air in the
cold water system.
