Dry oprehyɛn

Bere a ɔhyew a atwa yɛn ho ahyia no kɔ so<0℃, completely drain the spray system, turn off the spray pump, and use only fan air cooling (full dry mode) to completely eliminate the risk of spray water freezing.

Fa dry mode di kan wɔ ɔhyew a ɛba fam mu na ama ahoɔden a wɔde petepete so a wɔde di dwuma ne asiane a ɛwɔ hɔ sɛ awɔw bɛba no so atew. Fa fan ne pump frequency ne adesoa hyia na ama ahoɔden a wɔde di dwuma no so atew.

 

Yɛ nhyehyɛe a ɛfa asorɔkye a ɛyɛ nwini a egye ntɛmpɛ ho. Gyae aduru a wode petepete so wɔ ɔhyew a ɛba fam koraa mu, hyɛ nneɛma a wɔde siw mframa ano ne ɔhyew a ɛwɔ mu no mu den, na sɛ ɛho hia a, fa anyinam ahoɔden a wɔde yɛ hyew di dwuma bere tiaa bi.

 

 

Sɛ wɔde abantenten a ɛma onwini a wɔatoto mu di dwuma wɔ awɔw bere mu a, egye anti-freeze sɛ ase line, flow sɛ core, ne automatic control sɛ ɔkwan. Ɛnam insulation, ɔhyew a wɔhwehwɛ, dry/wet switching, parameter control ne mpɛn pii nhwehwɛmu so no, wobetumi akwati nnwinnade a wɔsɛe no esiane freezing mu no yiye, na wɔanya adwumayɛ a ahobammɔ wom, etu mpɔn na ɛmma ahoɔden-kora so.
